Features and Enhancements in Release 5.0.20

This section contains the following new features and enhancements in Release 5.0.20:

Multilink Frame Relay on MPSM-T3E3-155

Port Oversubscription on MPSM-T3/E3-155

Channel Loopback on MPSM-T3E3-155

Enhancement to Statistics Counters on MPSM-T3E3-155

Multilink Frame Relay on MPSM-T3E3-155

Multilink Frame Relay (MFR) combines multiple individual links into one logical interface, called an MFR bundle. Multilink bundles help bridge the gap between DS1 and DS3 bandwidths, and can increase resiliency because the failure of a link usually does not bring down the whole bundle. In the MPSM-T3E3-155, each link is a T1 path on a channelized DS3 line or path.

The bundle interface serves as the Frame Relay data link, and performs the same functions as a physical Frame Relay interface. The bundle interface is visible to peers, so you configure Frame Relay functionality on the bundle interface. This section describes how to provision Mulitlink Frame Relay (MFR) services on the MPSM-T3E3-155 card.


Note Before you perform the procedures in this section, you must first configure the MPSM-T3E3-155 card and lines.


Features

The MPSM-T3E3-155 provides the following features:

MFR supported on the 3-port channelized T3 back card and the 2-port channelized OC-3 back cards.

Maximum of 42 bundles with up to 12 links per bundle.

Support for Class A, Class B, and Class C bandwidth classes.

Bundling of links that belong to different channelized T3 (up to 3 T3s) or STS-1s (up to 3 STS-1s).

Aggregation of only full T1/E1 links. MFR bundles with NxDS0 links are not supported.

12 bit sequence number format.

Two-byte Frame Relay header supported.

Support only for Extended Super Frame (ESF).

Both UNI and NNI mode as per FRF.16.1 are supported.

MPSM is transparent to end-to-end MFR and cannot be the initiating or terminating end for end-to-end MFR.

FRF.2.1 Annex 1 is supported on NNI-type bundle interfaces.

Restrictions

The MPSM-T3E3-155 has the following restrictions:

Aggregation of full T1 links only; MFR bundles with n x DS0 links are not supported

Blending T1 and E1 is not supported

Two-byte Frame Relay header (for example, 10 bit DLCI) is supported

Four-byte Frame Relay header for extended addressing is not supported. Frame Relay extended addressing uses a 23-bit DLCI field that enables support for thousands of DLCIs in NNI networks.

Frame Relay fragmentation is not supported.

Super Frame (SF) mode is not supported. Only ESF (Extended Super Frame) mode is supported for MFR services.

A maximum of 200 DLCIs per bundle is supported.

Multilink Frame Relay Quick Start Provisioning Procedures

This section provides quick start procedures for provisioning MFR on the MPSM-T3E3-155.

Multilink Frame Relay General Provisioning Procedures

This section contains procedures for provisioning MFR on the MPSM-T3E3-155. You create SPVCs for MFR the same way that you create Frame Relay SPVCs.


Note To support MFR, both ends of a physical link must be MFR capable, and the MFR configuration must match on both ends.


Creating an MFR Bundle

The MPSM-T3E3-155 implements MFR service using MFR bundles, which contain one or more serial links. When you add a bundle, the MPSM-T3E3-155 creates the corresponding Frame Relay data link layer interface for the service. After adding a bundle, you can then add MFR links to the bundle.

When you add a bundle using the addmfrbundle command, you specify the bundle number and activation class only; all other bundle parameters assume default values. You subsequently configure other bundle parameters using the cnfmfrbundle command. For example, after adding a Class C bundle you also need to configure the minimum number of links that must be operational before the bundle is operational.

To create an MFR bundle, perform the following steps:


Step 1 Establish a configuration session with the MPSM-T3E3-155 using a user name with GROUP1 privileges or higher.

Step 2 Create an MFR bundle using the addmfrbundle command.

M8850_SF.10.MPSM155[FR].a > addmfrbundle <bundleNum> <activationClass>

Table 2 describes the parameters for the addmfrbundle command.

Table 2 addmfrbundle Command Parameters

bundleNum

Bundle Number, range 1-42

activationClass

Bundle activation class:

1=Class A—At least one bundle links must be operational for the MFR Bundle to be operational

2=Class B—All the bundle links must be operational for the MFR Bundle to be operational

3=Class C—Configured number of bundle links must be operational for the MFR Bundle to be operational.


This command creates a MFR bundle with the default configuration shown in Table 3.

Table 3 MFR Bundle Default Configuration 

Parameter
Description

minimumLinks

Specifies the minimum number of active links required for a Class-C MFR bundle to be operational. The default value is 1 link

helloTimer

Specifies the interval in seconds at which to send hello messages. The default is 10 seconds.

ackTimer

Specifies the maximum time period to wait for an acknowledgement message from the far end. The default is 4 seconds.

maxRetry

Specifies maximum number of times to re-try sending a hello message to the far end if an acknowledgement message is not returned. The default is 2 retries.

bundleName

Identifies the near-end bundle. The default bundle name is of the form node.slot.bundle, for example M8850_SF.Slot10.Bundle03


The following example creates MFR bundle 3 with Class A service type using default bundle parameters:

M8850_SF.10.MPSM155[FR].a > addmfrbundle 4 3

Step 3 To verify that the MFR bundle has been created, enter the dspmfrbundle <bundleNum> command, specifying the number of the bundle.

M8850_SF.10.MPSM155[FR].a > dspmfrbundle 4
    Bundle Number                   : 4

    Near End Bundle Name            : M8850_SF.Slot10.Bundle04
    Far End Bundle Name             : <not defined>


Configuring an MFR Bundle

When you add an MFR bundle, most of the configuration options are defaults (See Table 3). For example, if you want to add a bundle with a minimum number of links that is greater than one, you have to configure the minimum number of links is this procedure.

To configure an MFR bundle, perform the following steps:


Step 1 Establish a configuration session with the MPSM-T3E3-155 using a user name with GROUP1 privileges or higher.

Step 2 If the MFR bundle is administratively up, bring it down by entering the dnmfrbundle <bundleNum> command.

Step 3 Configure MFR bundle parameters using the cnfmfrbundle command.

M8850_SF.9.MPSM155[FR].a > cnfmfrbundle -bundle <bundleNum>  
[-class <activationclass>] [-minlinks <minimumlinks>] 
[-hellotimer <hellotimer>] [-acktimer <acktime>] 
[-maxretry <maxretry>] [-bname <bundleName>]

Table 4 describes the parameters for the cnfmfrbundle command.

In the following example, the user increases the minimum number of links for a Class C MFR bundle to 4 and sets the maximum number of retries to 4.

M8850_SF.9.MPSM155[FR].a > dnmfrbundle 4 
M8850_SF.9.MPSM155[FR].a > cnfmfrbundle -bundle 4 -minlinks 4 -maxretry 4

Step 4 Restore the bundle to the administrative up state by entering the upmfrbundle <bundleNum> command.

Step 5 To verify MFR bundle configuration, enter the dspmfrbundle <bundleNum> command, specifying the number of the bundle you want to display.

M8850_SF.10.MPSM155[FR].a > dspmfrbundle 4
    Bundle Number                   : 4
    Activation Class                : C

    Far End Bundle Name             : <not defined>


Adding Links to an MFR Bundle

After you have established and configured an MFR bundle, you can add links to the bundle. Adding a link sends an Add-Link request message to the far-end of the bundle. A link is actively operating in a bundle only after the following conditions are met:

An Add-Link acknowledgement is received from the Far end for the transmitted Add-Link message.

An Add-Link request is received from the Far-end.

After both messages are received from the far-end, the MFR link is ready to transmit and receive data. Depending on the Activation Class of the bundle, the Bundle Up Indication is sent by the MFR Bundle layer to the Frame Relay Data Link layer under the following conditions.

Class A bundles—After receiving link activation confirmation for one link.

Class B bundles—After receiving link activation confirmation for all links in the bundle.

Class C bundles—After a predefined number of links in the bundle confirm activation.

To add a link to an MFR bundle, perform the following steps:


Step 1 Establish a configuration session with the MPSM-T3E3-155 using a user name with GROUP1 privileges or higher.

Step 2 Bring up the links (paths) that you want to add to the MFR bundle by entering the uppath [-path_filter] <path_num> command. To display all available paths, enter the dsppaths -all command.

Step 3 Add links to the MFR bundle by entering the addmfrlnk command. The new link has a default name with the format node.card.link.

M8850_SF.10.MPSM155[FR].a > addmfrlnk <link> <bundleNum> 

Table 5 describes the parameters for the addmfrlnk command.

Table 5 addmfrlnk Command Parameters

Parameter
Description

link

Specifies a DS1 or E1 path:

DS3 payload: bay.line.sts:ds1

VT payload: bay.line.sts:vtg.vt

where: bay=1, line=1-3, sts=0-3, ds1=1-28,
tug3=1-3, vtg=1-7, vt=1-4 (VT15) or 1-3 (VT2)

Note Enter the dsppaths -all command to display all available paths on the card.

bundleNum

Bundle number, in the range 1-42

Note Enter the dspmfrbundles command to display all bundles on the card.


The following example adds link 1.1:11 (bay 1, DS3 1, DS1 11) to bundle 4.

M8850_SF.10.MPSM155[FR].a > addmfrlnk 1.1:11 4

Step 4 To verify that the link was added to the MFR bundle, enter the dspmfrlnk <linkNum> command, specifying the number of the bundle.

M8850_SF.10.MPSM155[FR].a > dspmfrlnk 1.1:11
  Link Number                      : 1.1:11

  Link Far End Name                : <not defined>
  Link Far End Bundle Name         : <not defined>
  Link PHY Operational Status      : Down


Configuring MFR Links

Optionally, reconfigure the near-end name of the MFR link. Links have a default near-end name in the format node.slot.link, for example M8850_SF.Slot10.Link11.

To rename a link, perform the following steps.


Step 1 Establish a configuration session with the MPSM-T3E3-155 using a user name with GROUP1 privileges or higher.

Step 2 Reconfigure the link by entering the cnfmfrlnk command.

M8850_SF.10.MPSM155[FR].a > cnfmfrlnk -link <lnkNum> -lname <linkname> 

Table 6 describes the parameters for the cnfmfrlnk command.

Table 6 cnfmfrlnk Command Parameters

  Link Far End Bundle Name         : <not defined>
  Link PHY Operational Status      : Down


Adding a Port to the MFR Bundle

You need to add a port to an MFR bundle to connect it to other endpoints.

To add a port to an MFR bundle, perform the following steps:


Step 1 Establish a configuration session with the MPSM-T3E3-155 using a user name with GROUP1 privileges or higher.

Step 2 Prepare to add a port to the MFR bundle:

a. Determine the bundle number on which you will add the port. To display a list of the MFR bundle numbers, enter the dspmfrbundles command.

b. Verify that the bundle and port number you want to use are not already configured. To display a list of the Frame Relay ports already configured on the MPSM-T3E3-155 card, enter the dspports command in the Frame Relay service context.

When you add a port, you must specify a port number that is unique on the MPSM-T3E3-155 card. For example, if port number (If Num) 5 is assigned, you cannot use port 5 on any other line or bundle on that MPSM-T3E3-155 card.

Step 3 Add and configure an MFR port for the MFR bundle by entering the addmfrport command:

M8850_SF.10.MPSM155[FR].a >addmfrport <ifNum> <bundle> <portType> <sct> 
[-rat <rat>] [-oversub <oversub>] 
[-lmiSig <lmiSigType> ] [-asynUpdt <updateType>] 
[-elmi <elmiState>][-segLmi <segLmiStatus>] 
[-t391 <t391Value>] [-t392 <t392Value>] 
[-n391 <n391Value>] [-n392 <n392Value>][-n393 <n393Value>] 

Table 7 lists the parameter descriptions for adding MFR ports.

Table 7 addmfrport Command Parameters 

ifNum

A number for the port, in the range 1-1003.

bundleNum

The MFR bundle number, in the range 1-42.

Note Enter the dspmfrbundles command to display all MFR bundles on the card.

portType

Type of logical interface (port):

1 = Frame Relay Service

3 = Frame Forward (Not applicable for MFR bundles)

sct

The Service class template (SCT) for the port, range 0-255.

Default: 0

Note The port SCT file must exist and be registered on the PXM disk before it is available for use. Enter the PXM dspscts command to view all registered SCT files on the PXM card.

-rat

The egress service ratio of the high priority and the low priority queues, range 0-15.

Enter 0 to indicate that no service ratio is configured. In this case, bandwidth is allocated to both the high priority and the low priority queues on demand, which means that traffic is dynamically allocated on a first-come, first-serve basis.

The default setting is 1. In this case, the traffic of the CBR and rt-VBR service categories is allocated to the high priority queue, while the traffic of the nrt-VBR, ABR, and UBR service categories is allocated to the low priority queue.

-oversub

Oversubscription control:

1 = enable

2 = disable (default)

-lmiSig

LMI signaling protocol type:

2 = No Signaling (default)

3 = StrataLMI

4 = AnnexAUNI

5= AnnexDUNI

6 = AnnexANNI

7 = AnnexDNNI

Note When LMI is configured, the maximum number of connections per port for Strata LMI port is 560 and for Annex A/D UNI/NNI port is 898.

-asynUpdt

Enables or disables asynchronous updates. Asynchronous updates are an extension to the LMI protocol that notify the user immediately of changes in PVC and Multicast status. Before enabling this feature, make sure that any DTE equipment you are connected to supports asynchronous updates from the network.

Asynchronous update control:

1 = Disable both Asynchronous Status Updates and Unsolicited Full Status (default)

2 = Enable Asynchronous Status Updates

3 = Enable Unsolicited Full Status

4 = Enable Asynchronous Status Updates and Unsolicited Full Status

-elmi

Enable or disable enhanced LMI. Enhanced LMI enables the automatic exchange of Frame Relay QoS parameter information between the DTE and DCE. When enabled on both the DTE and the MPSM port, this allows the DTE device to learn QoS parameters from the frame relay port and use them for traffic shaping, configuration, or management purposes.

1 = enable

2 = disable (default)

-segLmi

Segmented LMI control:

1 = enable

2 = disable (default)

-t391

T391 timer. This is the Link Integrity Verification polling timer. The user (DTE) sends Status Enquiry messages to the network (DCE) every T391 seconds. An error is recorded if a Status message is not received within T391 seconds. The T391 counter always applies to the user equipment. It applies to the user and network if NNI bi-directional polling is present. Range 5-30. Default: 10

-t392

T392 timer. This is the Polling Verification timer. The network (DCE) expects Status Enquiry messages from the user (DTE) every T392 seconds. If the network does not receive a Status Enquiry message from the user within T392 seconds and the timer expires, then the network records a missing Status Enquiry message by incrementing the N392 counter. This timer value must be set greater than the T391 timer. The T392 timer always applies to the network. It applies to the network and user if NNI bi-directional polling is present. Range 5-30. Default: 15

-n391

N391 counter. This setting establishes the Full Status (status of all PVCs) polling cycle. The user (DTE) sends a Full Report Status Enquiry to the network (DCE) every N391 polls. The N391 counter always applies to the user equipment. It applies to the user and network if NNI bi-directional polling is present. Range 1-255. Default: 6

-n392

N392 counter. This setting specifies the UNI/NNI error threshold. This is the number of errors during N393 events that will cause an error condition. This counter should be less than or equal to the N393 counter. This counter can apply to both the user (DTE) and the network (DCE). Range 1-10. Default: 3

-n393

N393 counter. This setting is the monitored UNI/NNI events count, which must be greater than the N392 counter. N392 errors during N393 events will cause an error condition. If the N393 counter is set to a value much less than the N391 counter, the port could go in and out of an error condition without notification to either the user equipment or the network. This counter can apply to both the user (DTE) and the network (DCE). The value of this parameter should be greater than that for the -n392 parameter. Range: 1-10. Default: 4


Step 4 To display a list of all Frame Relay ports configured on the MPSM-T3E3-155 card, enter the dspports command in the Frame Relay service context. Port numbers are listed in the ifNum (interface number) column. If you want to view information on a particular port, note the number of that port.

In the following example, the user adds MFR port 4 to bundle number 4 with service class template 0.

M8850_SF.10.MPSM155[FR].a > addmfrport 4 4 1 0

Step 5 To verify the port, enter the dspports command:

Deleting an MFR Bundle, Link, or Port

Use the following procedure to delete an MFR bundle, link, or port.


Step 1 Establish a configuration session with the MPSM-T3E3-155 using a user name with GROUP1 privileges or higher.

Step 2 To delete an MFR port, enter the delport <ifNum> command. You must delete connections to the port before deleting the port.

Step 3 To delete an MFR link, enter the delmfrlnk <link> command. You must delete the port before deleting the last link.

Deleting a link sends a Remove-Link request message to the far-end of the link. The bundle stops transmitting data on the link after the Remove-Link request has been sent. However, data received on the link is processed until the acknowledgement for the Remove-Link request is received.

Step 4 To delete an MFR bundle, enter the delmfrbundle <bundleNum> command. You must delete all links from the bundle before deleting the bundle.

Step 5 To verify the deletion of ports, links, or bundles, enter the dspports, dspmfrlnks, or dspmfrbundles commands respectively.


Port Oversubscription on MPSM-T3/E3-155

This release adds Frame Relay port oversubscription to the MPSM-T3/E3-155 card. When enabled, the total committed information rate of all connections on the port can exceed the physical port rate. However, traffic is always limited to the physical port rate.

This feature affects the following commands:

addport—new -oversub option to enable or disable oversubscription for a new port

cnfport—new -oversub option to enable or disable oversubscription for an existing port

dspport— also displays activation and oversubscription status for a port

The following table describes the oversubscription option.

-oversub <value>

Oversubscription control. Enter a number to enable or disable the oversubscription indicator, as follows:

1 = enable

2 = disable


Channel Loopback on MPSM-T3E3-155

Channel loopback is a feature that loops all channel traffic (data and OAM) back to the source. There are two types of loopback:

Ingress—loops incoming line (CPE) traffic back to the line

Egress—loops outgoing (network) traffic back to the switch

You specify the type of loopback when you activate a channel loopback. You activate, deactivate, and display channel loopbacks using the commands shown in Table 8. Channel loopback configurations are persistent, so they survive a card reset.

Table 8 MPSM-T3E3-155 Channel Loop Commands 

Command
Description

addchanloop

Activates a channel loopback

delchanloop

Features and Enhancements in Previous Release 5.0.10

This section contains the following new features and enhancements in Release 5.0.10:

CES Line Conditioning

MPSM Service Modules

PXM45 RAS

Standard Available Bit Rate (ABR) Mapping Changes (PER 4148)

License Management

AXSM-16-155-XG Feeder Support

Unique Device Identifier (UDI)

CES Line Conditioning

Previously, on a CESM card with structured ports, the line is not conditioned when an OAM AIS is received on a VC. For unstructured ports, the line is conditioned (AIS is sent on the line). Non line conditioning is a problem for applications that convert T1 to E1. For this application, a structured port of 24 time slots is created on both ends. Therefore, when the T1 line goes into alarm, the far end E1 line stays up.

This feature enables CESM-8-T1E1 and MPSM-8-T1E1 cards in CES mode to send AIS on the line if OAM AIS is received on any channel irrespective of other channels on the line. When line conditioning (lineCondition) is enabled on a connection and OAM AIS is received on the connection from the network, AIS is generated on the line. AIS generation is irrespective of other active connections on the line. Similarly, when the VC stops receiving OAM AIS from the network, AIS generation on the line is stopped. This parameter is only applicable to connections on a structured port.

The following limitations apply to CES conditioning:

1. This channel parameter is not available for configuration upload.

2. Two ends of the CES channels have enabled the line condition, and two ends of the lines have physical loop back. After removing one loop back and inserting back, two ends of the lines are stuck in alarm. The channel is also stuck in alarm.

3. Two ends of the CES channels have enabled the line condition, and two ends of the lines are connected to CPE. Two CPEs that keep having alarms and alarm recovering might cause the line to be stuck in alarm. However, this occurrence is of a very low probability.

Workaround for limitations 2 and 3 is to add a soft loop back (addnloop) to one line, or, disable the line condition from one end of the channel.

Platforms

The feature is supported on the following MGX switches:

MGX 8850 (PXM45)

MGX 8850 (PXM1E)

Platforms

The feature is supported on:

MGX 8850 (PXM45)

MGX 8830 (PXM45)

MGX 8950 (PXM45)

Standard Available Bit Rate (ABR) Mapping Changes (PER 4148)

According to ATM forum's TM4.0, ABR connections should have zero in CLP and EFCI bits in the ATM cell. To follow this recommendation, all Frame Relay cards reset CLP and EFCI bits of all outgoing ATM cells irrespective of the value of DE and FECN bits of the incoming frames.

In releases prior to 5.0.10, RM cell generation and DE --> CLP, FECN --> EFCI mapping control are available as a FRSM-8T1E1 card level features for StdABR connections. You can enable or disable RM cell generation and mapping through the command cnfstdabrctrl. Once enabled, all of the StdABR connections on the card behave in the same way.

In this release, you can enable or disable StdABR options at the port level, instead of the card level, by using the CLI command: cnfportstdabrctrl or xcnfport. The CLI command cnfstdabrctrl will be obsolete with the new firmware release.

The RM cell generation options remain the same for the port level as the card level. These options are

1. No RM cell generation, no mapping

2. No RM cell generation, mapping

3. RM cell generation, no mapping

4. RM cell generation, mapping

Platforms

The feature is supported on:

MGX 8850 (PXM45/B, PXM45/C, FRSM-8T1E1, MPSM-8-T1E1, PXM1E)

MGX 8830 (PXM1E)

License Management

Some new cards can provide optional services and features in addition to standard features. These optional features can be enabled by installing specific licenses on the node. The following licenses can be installed:

1. MPSM-8-T1E1 cards might require Rate Control (only for FR) licenses.

2. MPSM-T3E3-155 cards might require the following licenses: Multilink (which covers both IMA and MFR), Channelization, Rate Control (only for FR), and Multiservice.


Note CBSM licenses will not transfer to MPSM-8-T1E1 cards. Contact Cisco to obtain MPSM replacement licenses.



Note See Appendix F of the Cisco MGX 8850 (PXM1E/PXM45), Cisco MGX 8950, Cisco MGX 8830, and Cisco MGX 8880 Configuration Guide, Release 5 for more information about MPSM license procedures.

AXSM-16-155-XG Feeder Support

Previously supported on AXSM and AXSM-E cards, the feeder upstream capability is now supported using the AXSM-16-155-XG card. This feature enables PXM1 feeder nodes to be directly connected to PXM45 8850 and 8950 platforms.

Limitation

IGX feeder nodes are not currently supported.

Platforms

The feature is supported on:

MGX 8850 (PXM45)

MGX 8950 (PXM45)

Unique Device Identifier (UDI)

Cisco is adopting the Unique Device Identifier (UDI) product identification standard. UDI is an asset management feature that helps Cisco customers better track their Cisco products. Using UDIs, customers can further automate electronic inventory systems and better calculate uptime, thus reducing operating expenses.

The UDI is a combination of identifiers that create a unique value. The UDI includes the orderable Product Identifier (PID), the hardware version identifier (VID), and the product serial number (SN).

MGX releases 5.0.10 and higher support the Cisco-wide UDI initiative. To be compliant with this initiative, the following enhancements have been made for various physical entities, which include non-legacy service modules, switch chassis, and backplanes:

Five MIB objects of the entityPhysicalTable (in Entity MIB) are populated to provide information about the physical entity in accordance with UDI specifications. Of these five fields, the following combination is called the UDI:

PID (18 Characters) + VID (3 Characters) + SN (11 Characters).

Though the entityPhysical MIB table can be retrieved to view the above mentioned objects, a new CLI command, show inventory, is required by the UDI initiative. The new command's syntax and output fully conform to UDI standards.

For questions about UDI, contact udi-info@cisco.com.

Limitations

For older service modules, the VID field is not available because VID was not programmed into older service modules' NVRAM. Thus, this object is likely to be missing from older service modules, making older modules non-compliant.

Platforms

UDI is supported on platforms with MGX release 5.0.10 or higher. The feature is supported on:

MGX 8850 (PXM45

MGX 8850 (PXM1E)

MGX 8830

MGX 8950

This new AXSM-XG Service Module supports 124K connections and provides a full 2.4 Gbps of usable bandwidth per card.

Platforms

This feature is supported on:

MGX 8850 (PXM45)

MGX 8950

AIS Delay, Deroute Delay, Absolute Grooming

AIS Delay: Sending AIS/Abit during grooming might cause customers to revert to backup facilities. The AIS Delay feature provides a mechanism to delay AIS/Abit up to a configurable time. This feature was supported in Release 4.0. The SNMP support for this feature is provided in Release 5.0.

Deroute Delay: This feature allows some time for a failed NNI interface to recover at the physical layer, before the switch declares it as failed (due to say, LOS, LOF, AIS-P, and so forth). This feature was supported in Release 4.0. The SNMP support for this feature is provided in Release 5.0

Absolute Grooming: This feature allows grooming to use an absolute cost threshold in addition to a percentage of threshold change. The feature was supported in 4.0. In Release 5.0 grooming thresholds have been enhanced to support AW, CTD, and CDV metrics on a per service category basis for both Percentage and Absolute Grooming Thresholds. The SNMP support for this feature is provided in Release 5.0.

Platforms

This feature is supported on:

MGX 8850 (PXM45/PXM1E))

MGX 8950

MGX 8830 (PXM1E)

Soft Reroute

Currently during grooming process, the connection is derouted and rerouted when the connection is on a PNNI routed path. Even when the desired route is unavailable, the connection is derouted and rerouted using PNNI.

The soft reroute feature allows the user to move a routed SPVC/P from an incumbent working path to a new path with minimal loss of traffic. The existing connection along the path is not derouted until the connection has been established along a new path. Thus, soft route brings higher connection availability. Enhanced grooming process use soft reroute to route a connection on a desired PNNI path.

QoS is preserved and improved by soft reroute for the rerouting connection.

Platforms

This feature is supported on:

MGX 8850 (PXM45/PXM1E)

MGX 8950

MGX 8830 (PXM1E)

Point to Multipoint Support on PXM1E

MGX 8830 (PXM1E) and MGX 8850 (PXM1E) can be used in conjunction with an MGX (PXM45) in a network to support point-to-multipoint connections. The PXM45 hardware performs cell replication to multiple destination endpoints. The MGX with PXM1E functions as the originating node or as a via node of a point-to-multipoint connection. If necessary, MGX with PXM1E can be enabled to perform limited branching or cell replication to support multiple parties or leaves of a point-to-multipoint connection.

Point-to-multipoint connection is for applications such as data and video broadcasts and LAN emulation. This feature supports new real-time and non-real-time applications, for example: distance-learning, live broadcasts, conferencing applications, financial data delivery (stock market feeds), white board collaboration, video conferencing, data and file replication, and video on demand.

Network efficiency is enhanced since multiple streams of data can be replaced with a single transmission up to the multicast distribution point, typically a MGX with PXM45. Point-to-multipoint differs from broadcast in the sense that it will attempt to replicate packets only to specific destination endpoints in the multicast distribution tree versus sending packets to each endpoint as in straight broadcast.

Limitation

Enabling cell replication or branching of more than two leaves per root in the PXM1E node is not recommended for mission-critical point-to-multiple connections due to potential ATM cell drops. Cisco plans to enhance the PXM1E embedded hardware in the future to support cell replication for higher root/leaves ratio with minimal cell drops.

Platforms

This feature is supported on:

MGX 8850 (PXM1E)

MGX 8830 (PXM1E)

Enhancements to Route Optimization

The feature enables the CWM to support scheduled/on-demand route optimization. The existing commands are also enhanced to support "Orderly Grooming" and allow users to schedule the route optimization based on "day(s) of the week". Trunk utilization factor is introduced to prevent connections from grooming to heavily loaded trunks.

The enhancements to route optimization enable customers to administer route optimization of connections from the Management station. The route optimization enhancements also include orderly grooming and trunk utilization factors for effectively managing the network.

Platforms

This feature is supported on:

MGX 8850 (PXM45/PXM1E)

MGX 8950

MGX 8830 (PXM1E)

Priority Bumping

Priority Bumping involves derouting of other lower priority calls (lower than the incoming call priority) in order to free up resources so that the incoming higher priority call can be routed. Calls might have to be derouted on ingress and egress interfaces to free up resources. Bumping can happen at source, via, or destination nodes. This feature works for SVCs as well as SPVCs. SVCs, which do not have priority signals from CPE/SAPI (in case of voice calls) use the priority of the ingress interface.

Platforms

This feature is supported on:

MGX 8850 (PXM45/PXM1E)

MGX 8950

The product enhancement requests (PERs) in Table 14 were introduced in Release 5.0.00.

Table 14 Product Enhancement Requests in Release 5.0.00 

Enhancement Number or Description
Purpose

Deroute Delay (5048)

See feature description.

Support in PNNI/SMs (AXSM-E, PXM1E) for the CLI commands: tstpndelay and cnfconseq (5494)

For connection fault isolation, MGX provides CLI commands tstpndelay, cnfconsegep, dspconsegep, and delconsegep in earlier releases to debug the connection problem. This project adds the corresponding SNMP interface support and extends the tool to work on PXM1E uplink, AXSM-E, AXSM-XG, AXSM cards, and also broadband SPVC supports.

AIS Delay, Absolute Grooming (6600)

See feature description.

Secure Remote Terminal Interface (6670)

This feature introduces Secure Shell (SSH) functionality on the MGX. SSH provides a secure way to transfer TCP/IP traffic to/from an MGX node, by encrypting all traffic.

TACACS+ for centralized user/password database (7056)

Prior to Release 5.0, each MGX switch maintained its own authentication database and performed its own authentication. In Release 5.0, TACACS+ functionality allows setup of one or more centralized authentication servers.

MGX switches are able to perform authentication against the centralized database, making management easier. Also, prior to Release 5.0, MGX software provided five command privilege levels that could be assigned to a user to authorize execution of all commands allowed by the privilege level. Prior releases do not support authorizing specific command executions on a per user basis. TACACS+ allows customers to configure authorization for a user to execute specific commands.

SNMP support for Memory and CPU utilization statistics (6802)

This feature allows access to historical and real-time data about memory usage and CPU utilization statistics via an SNMP interface. Three MIBS support the above: CISCO-PROCESS_MIB, CISCO-ENHANCED-MEMPOOL-MIB, and CISCO-ATM-CONN-INFO-MIB.

POST, Online Diag, and HMM

POST, Online Diag, and HMM have been enhanced to ease usability and reliability. Commands have been modified and added. Starting in Release 5.0.0, test failures result in recovery actions being taken.


Service Class Template (SCT) File Information

This section contains SCT file information for Release 5.0.20.

MPSM-155

The following are MPSM-155 SCT Files:

MPSM155_SCT.PORT.1.V1: policing enabled; for ATM/FR ports > 4 T1 in bandwidth

MPSM155_SCT.PORT.2.V1: policing disabled; for ATM/FR ports > 4 T1 in bandwidth

MPSM155_SCT.PORT.3.V1:policing enabled; for ATM/FR ports <= 4 T1 in bandwidth

MPSM155_SCT.PORT.4.V1: policing disabled; for ATM/FR ports <= 4 T1 in bandwidth

MPSM155_SCT.CARD.1.V1: controls queue settings in the ingress

In addition, the card is equipped with default port and card SCTs built into the code. In case a problem occurs with loading any of the SCT files from the disk, the default SCT is used. The default port SCT is typically the same as MPSM155_SCT.PORT.4.V1. The default card SCT is the same as MPSM155_SCT.CARD.1.V1.

The following are the checksums for the SCT files:

MPSM155_SCT.PORT.1.V1: Checksum is = 0x88569bf5= 2287377397

MPSM155_SCT.PORT.2.V1: Checksum is = 0x21e18676= 568428150

MPSM155_SCT.PORT.3.V1: Checksum is = 0x3cb04789= 1018185609

MPSM155_SCT.PORT.4.V1: Checksum is = 0xd63b320a= 3594203658

MPSM155_SCT.CARD.1.V1: Checksum is = 0x808b3c54= 2156608596

PXM1E

The SCT bundle in Release 5.0.20 includes the following updates:

PXM1E_SCT.PORT.5

PXM1E_SCT.PORT.6

The default SCTs provided with Release 5.0.20 are as follows:

SCT 5 - policing enabled. In general, this is for use on UNI ports.

SCT 6 - policing disabled. In general, this is for use on NNI ports.

The checksums for the SCT files are as follows:

PXM1E_SCT.PORT.5.V1: Checksum is = 0xa287c4ee= 2726806766

PXM1E_SCT.PORT.6.V1: Checksum is = 0x79f6c93d= 2046216509

PXM1E_SCT.PORT.52.V1: Checksum is = 0x199550ec= 429215980

PXM1E_SCT.PORT.53.V1: Checksum is = 0xf6d53485= 4141167749

PXM1E_SCT.PORT.54.V1: Checksum is = 0xa39611dc= 2744521180

PXM1E_SCT.PORT.55.V1: Checksum is = 0x11a518f1= 296032497

See the following notes:

PXM1E does not support CARD SCT.

ABR VSVD parameters are not supported due to hardware limitation.

The above PXM1E SCT files apply to MGX 8850 (PXM1E) and MGX 8830.

Use SCTs with larger VC thresholds configured for the VSI signaling service type. The maximum VC threshold value must be at least 50000 microseconds for the VSI signaling service type. New SCTs 5,6 and 54, 55 (Cisco provided SCTs for the T3/E3, Combo cards and IMA group links respectively) have been released with minor version = 1.

Custom SCTs need to be upgraded to a new minor version if needed with the new recommended VC threshold values. You can gracefully upgrade an SCT with minor version change without any traffic impact. Refer to the SCT config chapter of the configuration guide for more details on how to upgrade a SCT file to a new minor version.

AXSM and AXSM/B

The following are the AXSM and AXSM/B files:

SCT 2: Policing enabled, PNNI

SCT 3: Policing disabled, PNNI

SCT 4: Policing enabled, MPLS and PNNI

SCT 5: Policing disabled, MPLS and PNNI

The checksums for the SCT files are as follows:

AXSM_SCT.PORT.2.V1: Checksum is = 0x78ccfb22= 2026699554

AXSM_SCT.PORT.3.V1: Checksum is = 0x987919a7= 2558073255

AXSM_SCT.PORT.4.V1: Checksum is = 0x775bfaa2= 2002516642

AXSM_SCT.PORT.5.V1: Checksum is = 0xe84c696a= 3897321834

AXSM_SCT.CARD.2.V1: Checksum is = 0x78ccfb22= 2026699554

The following new hardware is introduced in Release 5.0.10:

MPSM-T3E3-155

SFP-2-155

SMB-2-155-EL

MPSM-8-T1E1

MGX-XF-UI/B

AXSM-8-155-XG

Product IDs, Card Types, and APS Connectors

MGX 8850 (PXM45/PXM1E), MGX 8950, and MGX 8830 Product IDs and Card Types

Table 17 lists part number and revision compatibility for front and back cards in the MGX chassis. The table also lists whether an APS connector is required.

Table 18 presents a guide on which APS connector to use with which MGX chassis and front card.

In these tables:

R- means that this is a redundant card, for AX-R-RJ48-8E1, AX-R-RJ48-8T1, and AX-R-SMB-8E1 cards.

Either of these connectors work for the AXSM cards in the MGX 8850 (PXM45) switch: MGX-8850-APS-CON or MGX-APS-CON.

The PXM45 card is not supported in Release 5.0.00 and higher. The PXM45/B and PXM45/C cards are supported.

The SCSI2-2HSSI/B card has two different 800 part numbers, and both part numbers are valid.

The PXM1E-COMBO card is also known as PXM1E-T3E3-155 card.

MGX 8950 does not support the AXSM/A or the AXSM-E cards. If these cards are present, they will show up as "Failed" when the dspcds command is issued.

Service Context—Frame Relay

Modules—MPSM-T3E3-155

Enter the addmfrport command to add and configure a port for an MFR bundle.

Syntax

addmfrport <ifNum> <bundle> <portType> <sct>
[-rat <rat>] [-oversub <oversub>]
[-lmiSig <lmiSigType> ] [-asynUpdt <updateType>]
[-elmi <elmiState>][-segLmi <segLmiStatus>]
[-t391 <t391Value>] [-t392 <t392Value>]
[-n391 <n391Value>] [-n392 <n392Value>][-n393 <n393Value>]

Syntax Description

ifNum

A number for the port, in the range 1-1003.

bundleNum

The MFR bundle number, in the range 1-42.

Note Enter the dspmfrbundles command to display all MFR bundles on the card.

portType

Type of logical interface (port):

1 = Frame Relay Service

3 = Frame Forward (Not applicable for MFR bundles)

sct

The Service class template (SCT) for the port, range 0-255.

Default: 0

Note The SCT file must exist on the PXM disk. Enter the cnfcdsct command to verify that the appropriate SCT exists on the PXM.

-rat

The egress service ratio of the high priority and the low priority queues, range 0-15.

Enter 0 to indicate that no service ratio is configured. In this case, bandwidth is allocated to both the high priority and the low priority queues on demand, which means that traffic is dynamically allocated on a first-come, first-serve basis.

The default setting is 1. In this case, the traffic of the CBR and rt-VBR service categories is allocated to the high priority queue, while the traffic of the nrt-VBR, ABR, and UBR service categories is allocated to the low priority queue.

-oversub

Oversubscription control:

1 = enable

2 = disable (default)

-lmiSig

LMI signaling protocol type:

2 = No Signaling (default)

3 = StrataLMI

4 = AnnexAUNI

5 = AnnexDUNI

6 = AnnexANNI

7 = AnnexDNNI

Note When LMI is configured, the maximum number of connections per port for Strata LMI port is 560 and for Annex A/D UNI/NNI port is 898.

-asynUpdt

Enables or disables asynchronous updates. Asynchronous updates are an extension to the LMI protocol that notify the user immediately of changes in PVC and Multicast status. Before enabling this feature, make sure that any DTE equipment you are connected to supports asynchronous updates from the network.

Asynchronous update control:

1 = Disable both Asynchronous Status Updates and Unsolicited Full Status (default)

2 = Enable Asynchronous Status Updates

3 = Enable Unsolicited Full Status

4 = Enable Asynchronous Status Updates and Unsolicited Full Status

-elmi

Enable or disable enhanced LMI. Enhanced LMI enables the automatic exchange of Frame Relay QoS parameter information between the DTE and DCE. When enabled on both the DTE and the MPSM port, this allows the DTE device to learn QoS parameters from the frame relay port and use them for traffic shaping, configuration, or management purposes.

1 = enable

2 = disable (default)

-segLmi

Segmented LMI control:

1 = enable

2 = disable (default)

-t391

T391 timer. This is the Link Integrity Verification polling timer. The user (DTE) sends Status Enquiry messages to the network (DCE) every T391 seconds. An error is recorded if a Status message is not received within T391 seconds. The T391 counter always applies to the user equipment. It applies to the user and network if NNI bi-directional polling is present. Range 5-30. Default: 10

-t392

T392 timer. This is the Polling Verification timer. The network (DCE) expects Status Enquiry messages from the user (DTE) every T392 seconds. If the network does not receive a Status Enquiry message from the user within T392 seconds and the timer expires, then the network records a missing Status Enquiry message by incrementing the N392 counter. This timer value must be set greater than the T391 timer. The T392 timer always applies to the network. It applies to the network and user if NNI bi-directional polling is present. Range 5-30. Default: 15

-n391

N391 counter. This setting establishes the Full Status (status of all PVCs) polling cycle. The user (DTE) sends a Full Report Status Enquiry to the network (DCE) every N391 polls. The N391 counter always applies to the user equipment. It applies to the user and network if NNI bi-directional polling is present. Range 1- 255. Default: 6

-n392

N392 counter. This setting specifies the UNI/NNI error threshold. This is the number of errors during N393 events that will cause an error condition. This counter should be less than or equal to the N393 counter. This counter can apply to both the user (DTE) and the network (DCE). Range 1-10. Default: 3

-n393

N393 counter. This setting is the monitored UNI/NNI events count, which must be greater than the N392 counter. N392 errors during N393 events will cause an error condition. If the N393 counter is set to a value much less than the N391 counter, the port could go in and out of an error condition without notification to either the user equipment or the network. This counter can apply to both the user (DTE) and the network (DCE). The value of this parameter should be greater than that for the -n392 parameter. Range: 1-10. Default: 4

AXSM and AXSM-E Commands

There were no new or changed commands for AXSM and AXSM-E cards in MGX Release 5.0.10.

Limitations, Restrictions, and Notes for 5.0.20

This section includes information about limitations, restrictions, and notes pertaining to MGX Release 5.0.20.

Due to granularity limitations in the AXSME hardware, cell traffic does not reach the configured PCR rate when WFQ is enabled. You must configure connections that have WFQ enabled with a PCR of 101% of the actual required rate. ABR has the same Qbin priority as UBR in the SCT tables. In this case ABR and UBR share excess bandwidth if WFQ is enabled.

Upgrade to Release 5.0 and higher is only from 3.0.25 and higher.

The VXSM cards, when installed for the first time or after clearing the slot configuration, create default configuration. This creation of default configuration involves writing large amount of data to the hard disk in the node. When multiple VXSM cards are installed simultaneously or the configuration of multiple VXSM slots are cleared simultaneously, one or more VXSM cards could fail to be installed. This potential failure results in following recommendations (refer to CSCed12646):

Install VXSM cards, using setrev command, one at a time. Install another VXSM after the earlier one is installed completely and is Active.

Clear the VXSM slot configuration using clrsmcnf command (with no option where the slot primary software version is preserved) one at a time. Wait until the VXSM rebuilds after clearing its slot configuration (without clearing the slot primary software version) before clearing the slot configuration of another VXSM slot.

The percentage trunk utilization with overbooking is calculated using the following formula:

overbooked MaxCR - overbooked ACR) / overbooked MaxCR. This will occur when inter-operating with SES from Release 3.0.x and higher.

ACR = MaxCR - (trunk utilization / overbooking factor) and
overbooked ACR = ACR / overbooking factor
overbooked MaxCR = MaxCR / overbooking factor.

The overbooked ACR is calculated differently between MGX and SES.

On MGX, the bandwidth for all current connections on the port are considered overbooked when calculating the trunk utilization.

On the SES, the bandwidth for all current connections on the port are NOT considered overbooked when calculating the trunk utilization.

Therefore, the trunk utilization calculation is lower on the MGX than on the SES when there are existing connections on the port with an overbooking factor configured. This in turn yields a lower percentage trunk utilization on the MGX compared to the SES.

PXM45(A) card is not supported in Release 5.0.00 and onwards.

It is not recommended to turn on complex node for physical nodes (the lowest level node) since this increases memory usage but does not provide any benefits. Complex node should only be turned on for logical nodes.

AXSM-16-155-XG with MCC Back Cards

You might see the following scenario when the card to card APS is configured on one side but not the other side:

The Protection Line Status in dspapslns or dspapsln shows "OK" if the other side has added the card redundancy and upped the line but not the APS. If the backcards are SFP backcards, the Protection Line Status is in "SF" in the same setup.

From CLI screen on the side of APS added, the only way to find out if the remote APS has been added is through the Receive chanfield and modefield in dspapsln. See the following display based on the APS protocol configured:

For GR253:

Receive k2 chanfield - Null Channel

Receive k2 modefield - Undefined

After adding remote APS (with MCC):

Receive k2 chanfield - Null Channel

Receive k2 modefield - UNI1+1 or Bi depending on mode

For ITU (or AnnexA)

Receive k2 chanfield - Null Channel

Receive k2 modefield - Undefined

After adding remote APS:

Receive k2 chanfield - Null Channel

Receive k2 modefield - Undefined

For AnnexB:

Receive k2 chanfield - Null Channel

Receive k2 modefield - Undefined

After adding remote APS:

Receive k2 chanfield - Working Section 1 or 2

Receive k2 modefield - Undefined

Upgrading AXSM-XG Cards

The following notes apply to AXSM-XG card upgrades:

When installing AXMS-XG cards into a node that has a release earlier than Release 4.0.15, all of the other cards in the node must be upgraded first to Release 5.0.

When configuring virtual interfaces (for example, VUNI, VNNI, EVUNI, or EVNNI), the physical interface must be of all one ATM header type, either UNI or NNI. The signaling that is applied to a virtual port is independent of the actual virtual port ATM header. The only limit is that the VPI value must be within the UNI ATM header limitations.

Upgrading the VISM-PR Image

If you are upgrading the VISM-PR image to Release 3.2.1x or later and the PXM1E or PXM45 image from Release 4.x or earlier to Release 5.x, first upgrade the VISM-PR cards. Then, upgrade the PXM1E or PXM45 cards in the same node.

Do not configure the new VISM features until you have fully upgraded the network. After you upgrade your network to PXM1E or PXM45 Release 5.x or later and VISM-PR to Release 3.2.1x or later, apply the standard upgrade process.

MPSM Notes

See the following MPSM notes:

Neither the MPSM-8-T1E1 card nor the MPSM-T3E3-155 card support the LMI Autosense feature that is supported for FRSM cards since Release 1.2.21.

If a combination of RPM-PR and MPSM-T3E3-155 cards are being installed in slots covered by the same cell bus, then enable Option 10 of cnfndparms (auto clock rate setting) before installing the MPSM-T3E3-155 and RPM-PR cards. This note applies when two RPM-PR cards or two MPSM-T3E3-155 cards (or one RPM-PR and one MPSM-T3E3-155 card) are inserted into slots under the same cell bus master, for example, slots 5 and 6 or 3 and 4.

The MPSM cards are cell bus based cards, and they have some limitations that make it seem that only a few of these cards could be used in a chassis when running at full port rate.

In reality, the full port rate available is rarely used. Statistical multiplexing of traffic across many ports can allow overbooking of the cell bus capacity just as it allows overbooking of trunk capacity. Estimates on how much overbooking is practical without dropping cells relies on the network's characteristics such as the mix of service types, port speeds, and offered traffic loads as a percentage of port speed or as generated cell rates. Work with your Cisco Customer Engineering representative to help you characterize the quantity of MSPM cards suitable for your network.

If you order MPSM cards with systems, the MPSM license(s) will be shipped on the PXM card. For more information, refer to Appendix F of the Cisco MGX 8850 (PXM1E/PXM45), Cisco MGX 8950, Cisco MGX 8830, and Cisco MGX 8880 Configuration Guide, Release 5.

PXM1E Parity Errors

The following parity errors are

If CBC CBH RAM has parity error on active PXM1E card, and if no traffic is passing on any connections, then PXM1E does not detect this parity error and does not switch over to the standby card. Also, all Service Module cards reset. In a future release of MGX Release 5, the Online Diagnostics module will have a Cell Bus Parity test that will detect this condition and cause a switchover.

The PXM1E standby card still comes up when there is a QE TS RAM parity error. In future release of MGX Release 5, online diagnostics module will detect this condition on the Standby and cause the card to reset

Upgrading to 5.0

The following notes apply to upgrading to Release 5.0:

Any invocation of 'reboot 0' from shellconn to reset a PXM card results in an unconditional core dump on the card with reason "Reset From Shell". As a side effect, customers using the CLI command burnboot to upgrade the PXM boot revision to Release 4.0.10 release from any older release returns a "Reset From Shell" core dump while upgrading. This core dump should be ignored. No future upgrades will be affected by this.

PNNI trunk goes down temporarily after upgrade from Release 4.0.12 to 5.0. This upgrade problem is only seen in ILMI enabled E-VNNI/E-VUNI ports. As part of CSCec79854, ILMI behavior for E-VNNI and E-VUNI was changed. ILMI goes down as max_vpi and max_vpi_bits are exchanged differently between a virtual interface and non-virtual interface. Workaround has been documented in DDTS (see to anomaly CSCed44174).

Higher Level Logical Link Limits

The numbers of logical links in the higher levels of the PNNI hierarchy is limited to 30 per level when the complex node configuration is turned on. The limit is essential to reduce the processing time involved in finding the bypasses between the logical links. Whenever a significant change occurs in bandwidth in one of the links within the peer group, the bypass calculation is triggered and the bypasses are usually found from one logical link to another.

If there are n logical links, the calculation involves the finding n*n bypasses. If the number of logical links n is large, a lot of processing time is used for calculating the bypasses. The number of logical links per level must be limited to 30. The number can be controlled by configuring the appropriate number of aggregation tokens for the outside links for that peer group.

CLI Upgrade

During an upgrade when the standby card has a 3.0.23 release or later runtime firmware and the active card has a pre-4.0 runtime firmware version, no display output occurs from standby when cc command is issued. The error message "Err: cliSipcPsrRead(): received oversized message" appears from the active card. The workaround for this is

1. If PXM, connect to the console port of the standby if need to access it.

2. Complete the upgrade so that both service modules are running the same version.

The number of input characters for the CLI has increased from 256 to 512 bytes to accommodate more than 32 input parameters in 4.0 release firmware. When standby has 4.0 release firmware and active has pre 4.0 release firmware, the active is receiving 512 bytes, thus receiving the error message above.

Preferred Route

Preferred routes are not supported for connections with endpoints on RPM card types in Releases 4.0 and above.

Upgrading a preferred routing configured connection from any Release 3.0.x is non-graceful. During the upgrade, the preferred route identifier information for each connection is lost, and the preferred route identifier needs to be reprovisioned on the Service Module cards.

Also, the preferred route table at the PXM controller is lost. Connections that have already been routed with preferred routing remain, and no alarms for these connections occur. If a node in the PNNI network is removed via physical decommissioning and if any nodes in the network had some preferred routes that contained the removed node as one of the hops, the preferred route(s) must be deleted and modified manually.

When a connection is routed on a route other than its preferred route and if the preferred route becomes available, the connection is not automatically derouted to route back to its preferred route. You must deroute and reroute by using configuration commands (optrte, rrtcon, dncon/upcon, and so forth). QoS precedence over Preferred Route does not apply to MPG network (CSCdz40310).

A preferred route configured with a higher node ID cannot be blocked (CSCdz41145, CSCdz49001). Due to differences in physical port numbering, non-MGX nodes can only be the terminating nodes in a preferred route.

Preferred route status is supported, starting with MGX Release 5.0.00. This feature requires you to issue commands, such as cnfcon on each connection after an upgrade. This step is only needed once after the upgrade, and does not need to be repeated on subsequent upgrades.

AXSM-32-T1E1-E and PXM1E-16-T1E1

The following notes apply:

IMA version fall back is part of IMA group operation. If a group is configured with version 1.1 and it is connected to a far end group which is configured with version 1.0, this group falls back to version 1.0.

The IMA link Loss of IMA Frame (LIF) and Link Out of Delay Synchronization (LODS) defect integration times are configurable.

ATM layer configuration for line and IMA ports takes an additional parameter, AIS enable. It is enabled by default.

In T1 mode, payload scrambling is disabled by default and in E1 mode it is enabled by default on all lines and IMA groups.

Only 10 SVC calls per second is guaranteed.

FDL support for Loopback code detection is not supported.

Far End Line Performance counters are supported only for E1. They are not supported for the T1 interface.

HMM support is not available for the IMA and the Framer devices. When a switchover occurs, it can take up to 3.5 seconds for the IMA groups to recover. Data is lost until the groups recover.

IMA Auto-restart(persistent RX IMA ID) feature is supported.

IMA group cannot have links from upper and lower bays together.

ITC clocking mode on IMA is not supported.

One way transmission delay of more than 500 msec on the T1/E1 IMA links is not supported.

There is 5 ms fluctuation on IMA delay tolerance.

While the IMA group accumulated delay is being removed with clrimadelay, the following applies:

Any changes to this IMA group configuration are temporarily blocked.

Any changes in the FE IMA links in this group can cause the NE IMA group to restart.

The VC and COSB thresholds are updated when the links are added/deleted from the IMA groups.

The thresholds for the connections added when there are N links in the group can differ from connections added when there are (N+1) links in the IMA group.

BERT is only supported on the T1 interfaces. BERT is not supported on E1 interfaces.

The port number in the pnport (shelf.slot:subslot.port:subport) could be a random number. Do not interpret this number as line or IMA group number. Refer to DDTS CSCdy08500.

PNNI requires SCR = 453 cells per second and PCR = 969 cells per second for the control connection.

SSCOP requires of SCR = 126 cells per second and PCR = 2000 cells per second.

Cell Bus Service Modules (Formerly Known as Narrow Band Service Modules) and RPM-PR

When switchredcd is done and a PXM switchover (either through switchcc/resetcd on the PXM or due to a failure) happens at the same time (refer to anomaly CSCea36485), see the following:

Conditions: switchredcd is run from PXM command line to perform CBSM Switchover. PXM switches over (manual or automatic) before the Service Module (SM) switchover is completed.

Symptom: SM did not switchover after switchredcd.

If the PXM switches over before the CBSM switchover completes, the following issues can be seen:

The SM Switchover might not be complete and the standby card is in an indeterminate state. The dspcd command from PXM still shows it as 'standby' and later switchver (due to active SM removal or reset) fails, causing loss of traffic. The switchredcd command also fails.

The switchredcd from PXM again causes the failure since the standby SM is not able to allocate memory.

Work round: Reset the standby Service Module card.

CBSM feature is not available for PXM45/A.

CBSM (max dax con) has 13,500 connections.

CBSM (max non-dax) has 27,000 connections.

IGX Feeder

When an IGX is added as a feeder to a SES/BPX or MGX node, it will have a default node number. This node number might not be unique within the network. If the number is not unique, it needs to be modified to a unique node number by issuing cli command rnmnd <x> where x must be unique with respect to all other AutoRoute nodes. To find the other node numbers, use cli command dspnds +n. Failing to do so, could cause the CWM Databroker to have incorrectly formed hybrid connection database. The CWM GUI might show the connection as incomplete. IGX feeder is not support on AXSM-XG-16-155.

Policing Accuracy for PXM1E

A limitation exists with the policing accuracy for the PXM1E. The policing rate is defined as 50000000/PCR. If the PCR is comparable to the OC-12 line rate (1412830), the policing rate parameter is a relative small number (50000000/1412830 = ~35.38996).

Since integer division is performed, the decimal values are truncated. As a result, the policing parameter cannot be calculated accurately. Moreover, the policing rate parameter is stored in an exponent (5-bits) and mantissa (9-bits) format. This format cannot represent a small number accurately. Combining the above two factors, a 100% accurate policing parameter cannot be configured.

To ensure that you get the rate that you have specified, the software configures policing at the next larger rate which the hardware can support. For example, if you program a connection with PCR = 1400000, the software programs the actual policing rate to be 1428571. For a worse case scenario, if you configure a VBR2 connection with a PCR of 1400010 and the ingress user traffic is 1428570, there is not any policing because the ATM policing device would police at rate 1428571 only.

Maximum Threshold Accuracy for PXM45 and PXM1E

A limitation exists with the maximum threshold accuracy for the PXM45 and PXM1E. The Qbin threshold and VI rate are stored in the form of exponent and mantissa, and some accuracy is lost in expressing the real rate. In testing the thresholds, the lack of accuracy is compounded with both of the Qbin and VI rate (draining rate). Therefore, you cannot calculate an exact 100% correct discard rate.

To ensure that you get the rate that you have specified, the software configures Qbin depth at the next larger rate which the hardware can support. As a result, Int. Cell Gap (ICG) and Relative Service Delay (RSD) are truncated.

PXM1E-Based Switches

The following notes apply to PXM1E based switches—MGX 8850 (PXM1E) and MGX 8830:

Y-red is not supported on the MCC Electrical back card.

For inter-card APS to work on the PXM1E-8-155, and one front card is missing or not available, both backcards must be present. A front card cannot drive the alternate trunk back card when its own local trunk back card is absent.

MPLS controller is not supported on PXM1E.

PXM1E clock source is supported by VISM-PR, CESM, and AUSM cell bus service module cards. CESM and AUSM can provide one clock source, either primary or secondary.

Only SPVCs and SPVPs are supported on cell bus service modules. SVCs are not supported on CBSMs.

No bandwidth CACing support exists on the cell bus service modules, except for the RPM card, which is checked against the OC-3 card rate. For example, for a given RPM, the bandwidth allocated to all connections might not exceed the OC-3 rate. Bandwidth CACing is supported on the PXM1E uplink port.

The maximum bandwidth to be distributed among cell bus service modules is approximately an OC-10 rate while traffic on the network interfaces on PXM1E can achieve true OC-12 line rate.

Traffic must be balanced between the cell bus controllers to achieve the OC-10 rate. The traffic must be distributed equally at a rate of about OC-5 on the two cell bus controllers.

The cell bus controllers cannot load share to achieve OC-10 with one cell bus set at an OC-6 rate, and another cell bus set at an OC-4 rate.

Anything above OC-6 is dropped. However, if only one cell bus controller is used and the other cell bus controller is not used, then it can achieve an OC-10 rate. On an MGX 8850, the CBCs are split between the left and right side of the chassis: CBC0 supports slots 1-6 and 17-22 and CBC1 supports slots 9-14 and 25-30. On an MGX 8830, CBC0 supports slots 3,5,10, and 12 and CBC1 supports slots 4,6,11, and 13. Balance is achieved by planning the distribution of your cell base card by evenly distributing from the left side of the chassis and the right side of the chassis.

PXM1E Hardware Limitations

PXM1E hardware limitations are as follows:

For inter-card APS to work on the PXM1E-8-155 with one front card missing or unavailable, both back cards must be present. A front card cannot drive the alternate trunk back card when its own local trunk back card is absent.

During hardware upgrade from PXM1E-4-155 to PXM1E-8-155, at the time when the inserted card types are different (one PXM1E-4-155 card set and one PXM1E- 8-155 card set), the standby trunk back card functionality is not available. Therefore, LED functionality is not available, and APS lines do not work on that backcard.No modular optical transceiver (SFP-8-155) mismatches are reported for that backcard. No SFP-8-155 mismatches are reported during hardware upgrades.

Since the PXM1E-4-155 and PXM1E-8-155 backcards support LC and SC interfaces respectively, the following limitation/restriction applies:

For a hardware upgrade from PXM1E-4-155 to PXM1E-8-155, it is required that, after the first PXM1E-4-155 card set is replaced by the PXM1E-8-155 card set, any cabling for the PXM1E-8-155 interfaces is updated with a LC-SC converter.

Similarly, after the second card set is replaced, the same needs to be done for the interfaces on the new card set. If this is not done, the upgrade is not graceful and becomes service affecting, until appropriate cables are setup.

When MGX-8850-APS-CON is used, and one trunk-backcard is removed, screw the remaining backcard in completely to ensure that the contacts are complete.

MGX-8850-APS-CON limitation is

The Combo card does not require a mini-backplane. The PXM1E-8-155 REQUIRES a mini-backplane. The PXM1E-4-155 card does not require a mini-backplane. It is recommended that one be inserted to support graceful upgrade to PXM1E-8-155 cards in the future. Since the PXM1E-8-155 card requires a mini-backplane, if one is not already present when upgrading from PXM1E-4-155 to PXM1E-8-155, the upgrade cannot be graceful.

Reserved VCIs

You cannot provision the following reserved VCIs:

On a feeder trunk, VPI.VCI 3.8 is reserved for inband communication with the feeder shelf, and 3.31 is used for the feeder trunk Annex.G ILMI.

VPI = 0 and VCI = 5 are used for SSCOP for UNI signaling ports.If the port is configured for non signaling (univer = none), no VPI/VCI is reserved.

VUNI uses configured VPI and VCI = 5 for SSCOP.

EVUNI uses minimum VPI and VCI = 5 for SSCOP.

NNI uses VPI = 0, VCI = 18 for PNNI RCC.

VNNI uses configured VPI for the port and the VCI = 18 for PNNI RCC.

EVNNI uses minimum VPI and the VCI = 18 for PNNI RCC.

VPI = 0 and VCI = 16 are used for ILMI if ILMI is enabled. VUNI and VNNI uses configured VPI for the port and VCI = 16 for ILMI. Similarly, ILMI for EVNNI or EVUNI uses a minimum VPI and VCI = 16.

If MPLS is configured, VCI = 33 in the similar fashion as above.

If NCDP is configured, minimum VPI and VCI = 34 for NCDP clocking.

VPI = 0 and VCI = 31 are used for online diagnostics.

AXSM-E OAM

The following notes apply to AXSM-E OAM cells:

Any connection can receive E2E/OAM loopback cells up to the line rate (as long as the policing policy permits).

If the connection is not in the loopback mode and is operating in the normal mode, then the AXSM-E card can receive up to 1,500 segment OAM loopback cells per second. Any excessive segment OAM loopback cells are dropped. This limitation applies for all the connections on a card.

For example, if only one connection exists, that connection can receive 1,500 segment OAM loopback cells per second. If 2,000 connections exist on an AXSM-E card, and one segment OAM loopback cell per second is being pumped through on each connection, then there can only be up to 1,500 connections to receive loopback cells at any given second. The additional 500 connections are not received for that second.

The limitation is 1,500 segment OAM loopback cells per card and not per connection. The 1,500 cps assumes an even flow rate.

CLI Configurable Access

The following notes pertain to how command access levels can be configured:

Not all CLI commands are allowed to be changed and a command cannot be changed to CISCO_GP group access level.

Only the switch software is allowed to generate the binary file. This file has an authentication signature which has to be validated before the file can be used. Any manual changes to the file would make the file void.

If the binary file becomes corrupted, then the command access levels revert back to the default values during the card bring-up. To recover, repeat the installation process or retain a copy of the binary file and do cnfcli accesslevel install on that service module.

Currently, command names are verified, but an invalid command name might be parsed and be added to the binary file. However, this invalid name is ignored later.

If replication to standby failed, the installation process failed.

The cnfcli accesslevel default command restores all command access levels to default for the service module that this command is executed on. This command does not remove the binary file, and this change is not persistent. If the command is executed on the active card of a redundancy pair, the standby card is not affected. When the card is reset and the binary file exists, it will configure from the binary file when it is brought up.

Controller Card Mastership Sanity Verification

Because the solution provided in this release can only detect and log invalid mastership state transitions, an outage may still occur.

Serial Bus Path Fault Isolation

The Serial Bus Fault Isolation feature only addresses isolating errors on the local cards. However, when a common error occurs on the switching fabric card, this solution does not address the error. As a result, if there is a problem on the PXM card or the XM60, the fault is going to be reported against all cards that detected the symptoms of this problem.

Cell Bus Path Fault Isolation and Recovery

The following notes pertain to cell bus path faults:

The isolation procedures can isolate the cell bus path involving the QE SAR that is used for polling the serial bus based service modules (for example, AXSM, AXSM/B, AXSM-E,) and all communication with the standby controller card and the Cell Bus Based Service Modules (for example, FRSM, CESM). These procedures cannot isolate the cell bus path failures involving ATMizer SAR that is used for the inter-card communication except polling, between the active controller card and the serial bus based service modules.

The isolation procedures isolates the cell bus path failures to the active controller card only. This means it is determined whether the active controller card has the fault for the inter-card communication over the cell bus from the active controller card to the service modules and the standby controller card or not. It does not isolate the fault if the active controller card fails to communicate with some cards and successfully communicates with the rest on the cell bus.

At least two cards (two service modules or one service module and one standby PXM) must exist for the isolation procedures to be able to isolate the cell bus path failures to the active controller card.

Only the failures detected by periodic polling triggers the isolation procedures. Failures reported from other sources in the system against a service module or the standby controller card, due to the cell bus path failures, do not initiate the isolation procedures. This results in resetting that card against which the failure is reported, even while the active controller card is in the process of isolating the cell bus path failures triggered by the polling failures.

No separate trap or alarm is generated against the active controller card cell bus path when the fault is isolated to the active controller card. Only the event logs that are available can be used during the manual investigation triggered by the card reset and/or switchover traps.

If no controller card redundancy is available, isolating the cell bus path failure to active controller card results in outage. The active controller card is reset.

Disk Space Maintenance

Because the firmware does not audit the disk space usage and remove unused files, the disk space in C: and E: drives must be manually monitored.

Manually delete any unused saved configuration files, core files and firmware files and the configuration files of the MGX-RPM-PR-256/512 and MGX-RPM-XF-512 cards to avoid a shortage of disk space required to store event logs: configuration upload files in the C: drive and the configuration of MGX-RPM-PR-256/512 and MGX-RPM-XF-512 cards in the E: drive.

The following steps are recommended to remove files on the system from the active controller card:


Step 1 Change to the directory that needs grooming.

CLI cc <directory_name> 

Step 2 List the directory to identify old files that can be removed and available disk space.

CLI ll 

Step 3 Remove any old files (you may also use wild cards in the filename).

CLI rm <complete_filename> 

Step 4 List the directory to see if the file has been removed and disk space is available.

CLI ll 

Non-native Controller Front Card and PXM-HD Card

The following notes pertain to non-native front card controllers and the PXM-HD card:

When the front controller cards or the PXM-HD back cards are swapped within the same system, the system performs a non-native card check. As a result, the controller card that attempts to come up as Active/Active might get reset twice.

When a non-native PXM1E front card or a PXM-HD card is inserted into the standby controller slot, after the standby controller front card becomes Active/Standby, the active controller front card copies its hard disk content over to the standby controller card. The active controller front card does not perform any automatic hard disk content removal from the active or standby controller card.

The system keeps only the two most recent copy of the saved system configuration under the C:/CNF directory. You can use ftp protocol to ftp all the saved configuration under C:/CNF to their local server for future reference. All files under C:/CNF are not replicated over to the standby controller card under any circumstances.

clrsmcnf Command

These notes pertain to the clrsmcnf command:

Cisco does not recommend executing clrsmcnf on more than one card at a time

For the clear service module configuration feature, if there is a controller card switchover before the clear service module configuration operation is complete, the clrsmcnf command needs to be re-issued to ensure that the configuration is completely cleared to avoid any incomplete cleanup.

For the clear service module configuration feature, using the clrsmcnf command might result in discrepancy in the PNNI configuration. For example, some connections might be in the mis-match state.

If the clrsmcnf command is given with the <all> option to clear the software version for the slot as well, then the card goes into the boot/empty state after the operation is complete.

If the clrsmcnf command is given with the <all> option, for cell bus service module, the card goes into boot/empty state. For a broadband service module (for example, AXSM or MPSM-155-T3E3), the card goes into fail/active state.

While using the clrsmcnf command, the card in the specified slot is not usable until the operation has successfully completed.

APS

These notes pertain to the APS feature:

For AXSM APS, the backcard of the active card must be present for APS to function.

AXSM cards need the backcard of the active front card for the APS to work. This implies that AXSM cards do not support the cross backcard removal—the upper backcard of one AXSM and lower backcard of another AXSM.

If you remove the upper backcard of the active front AXSM, it triggers switching active card. At this point the APS is OK. However, if the lower backcard of the current active AXSM is removed at this time, it will not trigger switching active card since the standby card is missing one of the backcard. At this point the lower backcard APS does not work since the backcard of the active front card is missing.

Port LED lights on AXSM-E, AXSM-XG and PXM1E front cards indicate the receive status of physical line connected to it only when the card is in active state. For a standby AXSM-E, AXSM-XG, and PXM1E cards, the LEDs always remain green whether the lines are in LOS irrespective of which lines are Active (refer to anomaly CSCdv68576).

Path and Connection Trace

These notes pertain to the path and connection trace features:

Path trace is not supported on the control port.

Path trace does not have the accurate information when there is a crankback on the connect path.

Path and connection trace since Release 3.0.00 is not compatible with the path and connection trace available with previous releases.

Path and connection trace support point to point connections.

Path and connection trace support MPG (multi-peer group) and SPG (single-peer group).

Simple Network Timing Protocol (SNTP)

The CWM MIB is not supported in the release.

Priority Routing

These notes pertain to the priority routing feature:

Prioritized reroute of SPVCs is not guaranteed if the SPVCs originate on a signaling port. SPVCs might get routed out of order. In-order routing of SPVCs is guaranteed on non-signaling ports.

RPM does not support configuration of routing priority. All RPM mastered SPVCs are assigned a routing priority of 8 by the PXM.

The addcon command on SES does not have support for specifying the routing priority. All the added SPVCs are assigned a routing priority of 8. The cnfcon command can be used to change the routing priority of the SPVCs.

Changing the routing priority for dax connections does not change the priority of the associated SVCs. The SPVCs are not derouted and rerouted if just the endpoint parameters are changed, and routing priority is an end-point parameter. Also, since dax connections are never derouted even when the UNI port goes down and the rrtcon command is not supported for dax connections, the routing priority change never gets reflected. The only way for this to get reflected is to do a dncon and upcon. Since dax connections are never derouted, the effect of this limitation is voided.

Priority routing operates in a best effort manner for the following reasons:

Two in-order releases can still arrive out of order at the master node if they take two different paths.

Under congestion scenarios releases can be expected to be transmitted out-of-order. This is because releases of other calls must not be held up if you are not able to send releases on one of the interfaces because it is congested. The calls that were not released could be higher priority calls.

Lower priority SPVCs can be routed ahead of higher priority SPVCs. This can happen if you have attempted several times to route higher priority SPVCs, but failed. To prevent starvation of lower priority SPVCs, software will start to route lower priority SPVCs and software will get to the higher priority SPVCs at a later point in time.

SPVC Interop

These notes pertain to SPVC interoperability:

NNI SPVC Addendum Version 1.0 is not supported.

PNNI 1.0 Addendum (Soft PVC MIB) is not supported.

Terminating single-ended SPVCs on MGX switch with legacy service modules is not supported.

Origination of single-ended SPVCs (with -slavepersflag) from legacy service modules (FRSM, CESM and RPM) is not supported.

CC (Continuity Check) shall not be available at the slave end of a single-ended SPVC.

Reporting AIS detection to CWM is not available at the slave end of a single-ended SPVC.

tstdelay is not available at the slave end of a single-ended SPVC for MGX 8850. In case of SES-PNNI, the command is available from the PXM even for the slave endpoint.

The slave end of a single-ended SPVC is not visible to CWM.

If single-ended SPVCs originated from MGX switches, they can only be configured via CLI and not from CWM in the current release.

Single-end provisioning is not supported for DAX connections as no value addition is seen for interoperability.

SPVC statistics are not available for the slave endpoint of a single-ended SPVC because this endpoint is non-persistent.

When the persistent slave endpoint of an existing SPVC connection is deleted and the master endpoint is allowed to remain, the connection might get established as a single-ended SPVC connection. In this case, CWM shows the connection as "Incomplete."

Override of SVC connections on a VPI due to an incoming SPVP request for that VPI is not supported The following override options alone are supported:

spvcoverridesvc

spvcoverridesvp

spvpoverridesvp

Persistent Topology

These notes pertain to the persistent topology feature:

In a mixed network of pre-Release 4.0.00 and 4.0.00 or later nodes, only the node name and the node ID are shown for a pre-Release 4.0.00 node in the Topo DB. This is because the feature is not present in pre-Release 4.0.00 nodes.

If a peer group is made up of physical nodes with pre-Release 4.0.00 logical nodes, the information for the logical node is stored in the Topo DB. This is because there is no way to distinguish between physical nodes and pre-Release 4.0.00 logical nodes. Logical nodes with Release 4.0.00 or later software release are not stored in the Topo DB.

To delete a node information entry from the Topo DB, first remove the node from the network, either by disconnecting the cables or by downing all the links between that node and the network. Wait for an hour. Then, delete that node from the Topo DB. This is done because, even if a node is removed from the Topo DB of all nodes in the peer group, its PTSEs are still stored in the other nodes until they are flushed from those nodes. This would happen within an hour's time, but it is configurable as a PNNI timer value. If the node is deleted from the Topo DB within that hour's time, and the node does switchcc/reboot, then it's possible that the node info for that deleted node will be added back into the topo db.

When the node ID of a node is changed, the old node ID is added back into the Topo DB as a new node entry. In addition, the old node ID still is stored in the Topo DB of all the other nodes in the peer group. To delete this entry, wait for an hour so that the PTSEs with the old node ID is flushed from the DB of all the nodes in the peer group. Then, delete the information of the old node ID from the Topo DB.

It is possible that the gateway nodes are not in sync in a peer group, and this could happen in many situations. For example, a gateway node is added in a peer group, then a node is deleted from the PG, and another gateway node is configured, then the info for the deleted node would not be in the second gateway node. Another example is that a node is deleted from one gateway node, but not in another gateway node.

When deleting a node from the peer group, the node info must be deleted from all the nodes in that PG, even the non-gateway-node nodes. Otherwise, the node info for that deleted node will still be in the non-gateway-node nodes. This could cause inconsistencies later if this node is configured to be a gateway node.

Manual Clocking

These notes pertain to manual clocking:

AUSM can support only one clock. If a second clock is configured on the same AUSM card, AUSM provides negative acknowledgement. Attempts to configure the second clock will fail silently.

No clock sources are supported on FRSM. If a clock source is configured on FRSM, it will not be reflected in the database.

When resetcd is invoked, the primary and secondary (if configured) clock sources are recommitted. However, the clock to which the node is latched is not requalified. Only the backup clock is qualified if present. Recommitted means that the primary and secondary get requalified, and the node temporarily latches onto the internal oscillator. After the clock is requalified, the node locks onto the primary clock source once again.

AXSM Cards

If ER stamping is used, the rate interval does not provide sufficient accuracy to be completely effective. As a result, when an AXSM card is supporting a PNNI link which is congested with mixed CBR/ABR traffic, cells are dropped. This condition only occurs when ER stamping is enabled and CI is disabled on an AXSM PNNI link with CBR/ABR traffic running to cause congestion on the link.

It is recommended that the CI/EFCI mechanism be used for rate feedback rather than the ER stamping mechanism, especially if CBR/ABR traffic is expected. (Refer to anomaly CSCdw63829.)

AXSM-XG Hardware Limitation

The IR/LR/XLR SFP modules need a 10 db attenuator when connected with short cables. Otherwise the specification for receiver sensitivity on the receiver is exceeded.

ATM Multicast

The recommended configuration for MGX 8950 with ATM multicast application is as follows:

MGX 8950 system loaded with AXSM/Bs without any AXSM-XG cards in the system

MGX 8950 system loaded with all AXSM-XG based cards without AXSM/Bs in the system.

The MGX 8950 system having a mix of AXSM-XG based card and AXSM/Bs is not a recommended configuration for ATM Multicast application. The limitation is due to the behavior of backplane serial buses in the system. The suggested workaround:

For the MGX 8950 system with AXSM-XG based card and AXSM/B card to be present in the network supporting ATM multicast the PNNI node configuration can be made as branching restricted. cnfpnni-node 1 -branchingRestricted on

Priority Bumping

When you enable priority bumping on the node, you cannot change the booking factor for AXSM signaling ports. You can change the booking factor for non-signaling ports.

Other Limitations and Restrictions

Other limitations and restrictions are as follows:

When configuring virtual interfaces (for example, VUNI, VNNI, EVUNI, EVNNI), the physical interface must be of all one ATM header type, either UNI or NNI. The signaling that is applied to a virtual port is independent of the actual virtual port ATM header. The only limit will be that the VPI value must be within the UNI ATM header limitations.

If command clrchancnt is executed while a dspchancnt command is currently active, the data displayed is incorrect. Restarting the dspchancnt after the previous one has completed displays correct data.

The clrsmcnf command does not work for redundant service modules.

The clrsmcnf does not work if an upgrade is in progress.

If RPM-PR or RPM-XF is configured as a Label Switch Controller (LSC), execution of clrsmcnf command on those LSC slots is rejected as designed.

Configuration information is not synchronized between PXMs during upgrades. If any changes are made to the configuration during upgrades, the standby PXM must be rebooted. The standby PXM must be rebooted when it is in a stable state.

The maximum number of connections supported in Release 3.0.00 or later with PXM45/B is 250,000 connections.

NCDP is not supported on BPX.

CSCdz33652: When you clear the chancnt while you are monitoring the chancnt, the counters return invalid values on the dspchancnt display (AXSM-XG).

Clearing the Configuration on Redundant PXM45 and PXM1E Cards

These notes apply to redundant cards.

Due to checks to prevent an inserted card from affecting the system, an additional step might be required when inserting two non native PXM45 (or PXM1E) cards in a shelf. Insert the first PXM45, use the clrallcnf command, and allow this to become active before inserting the second PXM45 (or PXM1E).

After a clrallcnf, explicitly clean up stale SCT files (see anomaly CSCdw80282).

Troubleshooting APS Lines

Port light behavior changed in Release 3.0.00.

Port lights on AXSM/B front cards indicate the receive status of APS lines. The active front card always displays the status of the active line. The standby card always displays the status of the inactive line. If only one APS line fails, the line failure LED is always displayed on the standby front card.

Port lights on AXSM/B front cards indicate the receive status of the physical line connected to it. For example, when APS is configured for working line as 5.1.3 and protection line as 6.1.3, regardless of which card is active, port LED on card 5 shows the receive status of 5.1.3. Card 6 shows the receive status of 6.1.3.


Caution When the active front card and the active line are in different slots and the inactive line has failed, it is easy to incorrectly identify the failed line as the line in the standby slot. To avoid disrupting traffic through the active line, verify which physical line is at fault before disconnecting the suspect line.

If the active line fails and the standby line is not available, the switch reports a critical alarm.

If the active line fails and the standby line takes over, the former standby line becomes the new active line, and the switch reports a major alarm.

If an AXSM/A front card fails, APS communication between the redundant front cards fails. This can result in one of the following situations:

If both APS lines were working before the failure, an APS line failure causes a switchover to the protection line

If either APS line failed prior to a front card failure, a failure on the active line does not cause a switchover to the other line. Because the standby front card failed, it cannot monitor the standby line and report when the line has recovered. This means that the active card cannot use the standby line until the standby front card is replaced and the line problem corrected.

Use the following procedure to troubleshoot APS lines.


Step 1 Enter the dsplns command to determine if the line in alarm is an APS line. The dsplns  command shows which lines are enabled for APS.

M8xx0_.1.node.a > dsplns
                                           Medium Medium 
  Sonet  Line     Line     Line    Frame   Line   Line     Alarm   APS 
  Line  State     Type     Lpbk   Scramble Coding Type     State   Enabled
  ----- ----- ------------ ------ -------- ------ -------  -----   -------- 
   1.1     Up sonetSts12c NoLoop   Enable  Other ShortSMF    Clear Enable
   1.2     Up sonetSts12c NoLoop   Enable  Other ShortSMF    Clear Disable
   2.1     Up sonetSts12c NoLoop   Enable  Other ShortSMF    Clear Disable
   2.2     Up sonetSts12c NoLoop   Enable  Other ShortSMF    Clear Disable

If the line in alarm is an APS line, and has always functioned properly as an APS line, proceed to Step 2.

If the line in alarm has never functioned properly as an APS line, verify that the following are true:

Redundant front and back cards are in the appropriate bays and are installed at both ends of the line.

The cable is properly connected to both ends of the line.

APS connector is installed properly at both ends of the line (dspapsbkplane).

Step 2 Enter the dspapslns command at both ends of the communication line to determine whether one or both lines in an APS pair are bad.

Use Table 21 to help you determine which APS line is not functioning properly.


Note Table 21 is updated for Release 3.0.00.

If one or both lines appear to be bad, determine whether the working or protection line is in alarm. Troubleshoot and correct the standby line first. Replace the components along the signal path until the problem is resolved.

If the dspapslns command at either end of the line indicates a front or back card problem, resolve that problem first (see Table 22 to troubleshoot card problems).

If the dspapslns command shows a signal failure on the standby line, replace that line.

If the standby line is still down, replace the cards along the signal path.

CSCeg40352

Headline: Link Persistency OIDs return incorrect values

Symptom: There are three MIB variables on the MGX 8850 PXM45 switch platform that are populated improperly under a loopback condition on a PNNI link port. This therefore leads to the Link Persistency feature to not work properly for the scenario where a PNNI link port is put into loopback.

Conditions: PXM45-based MGX running 3.0(20) or 5.0(10.200) configured with PNNI links to another PXM45-based MGX running 3.0(20) or 5.0(10.200) and a soft loopback added (local or remote) to the PN port of a PNNI link (AXSM line cards). CWM 15.0 Patch 2.

Workaround: None.

The caviIngRcvClp0Cells counter are not counting ingress received Clp0 Cells. The value is always 0. The caviEgrXmtClp0Cells counter is incrementing, but the value is always the same as caviIngXmtClp0Cells although the counters are different on the cli.

Conditions: Only the caviIngRcvClp0Cells and caviEgrXmtClp0Cells counters are incorrect. The caviEgrRcvClp0Cells and caviIngXmtClp0Cells are the same as on the cli.

Workaround: Collect the counters from a dspportcnt on the cli.

Hardware: pxm1e

CSCeg43495

Submitting a Service Request

Using the online TAC Service Request Tool is the fastest way to open S3 and S4 service requests. (S3 and S4 service requests are those in which your network is minimally impaired or for which you require product information.) After you describe your situation, the TAC Service Request Tool provides recommended solutions. If your issue is not resolved using the recommended resources, your service request is assigned to a Cisco TAC engineer. The TAC Service Request Tool is located at this URL:

http://www.cisco.com/techsupport/servicerequest

For S1 or S2 service requests or if you do not have Internet access, contact the Cisco TAC by telephone. (S1 or S2 service requests are those in which your production network is down or severely degraded.) Cisco TAC engineers are assigned immediately to S1 and S2 service requests to help keep your business operations running smoothly.

To open a service request by telephone, use one of the following numbers:

Asia-Pacific: +61 2 8446 7411 (Australia: 1 800 805 227)

Definitions of Service Request Severity

To ensure that all service requests are reported in a standard format, Cisco has established severity definitions.

Severity 1 (S1)—Your network is "down," or there is a critical impact to your business operations. You and Cisco will commit all necessary resources around the clock to resolve the situation.

Severity 2 (S2)—Operation of an existing network is severely degraded, or significant aspects of your business operation are negatively affected by inadequate performance of Cisco products. You and Cisco will commit full-time resources during normal business hours to resolve the situation.

Severity 3 (S3)—Operational performance of your network is impaired, but most business operations remain functional. You and Cisco will commit resources during normal business hours to restore service to satisfactory levels.

Severity 4 (S4)—You require information or assistance with Cisco product capabilities, installation, or configuration. There is little or no effect on your business operations.
