cnfabr
Configure ABR—PXM1E
In general, the cnfabr command configures the VS/VD-specific parameters for an existing ABR connection. The connection must be of service type ABR (in the addcon command, service type=10).
Note
The only ABR parameters that the PXM1E supports are MCR and PCR.

cnfabrtparmdft
Configure ABR Traffic Parameter Defaults—PXM45, PXM1E
The cnfabrtparmdft command lets you configure default, ABR-specific parameters for all ABR SPVCs on a PNNI port. These parameters apply to SPVCs only.
Note
When you add an ABR connection, the controller provides the default ABR traffic parameters before the connection is committed. The default ABR traffic parameters are used in the SETUP message at the source when an SPVC with ABR service is set up. (Note also that you can change VS/VD-specific parameters for an individual ABR connection by using the cnfabr command on the AXSM-E.)

cnfaddrcug
Configure Address CUG—PXM45, PXM1E
The cnfaddrcug command lets you configure the following attributes for an existing CUG member (a CUG member is an ATM address):
•
•
•
After you add the first CUG member with the addcug command, its ATM address becomes a CUG member (or user), and only after that addition can you modify these CUG's attributes with the cnfaddrcug command. This command applies to an individual CUG member, whereas the addcug and cnfcug commands apply to a CUG. The paragraphs that follow describe the member attributes.
Preferential CUG
A preferential CUG serves as a default CUG. It applies when a calling party does not signal a specific CUG. For example, if CPE does not support CUGs, so that no CUG index is signalled by the calling party, the called party uses the preferential CUG to validate the call. You can designate one of the CUG's associated with a calling address to be the preferential CUG. To indicate which CUG is the preferential CUG, you must provide that CUG's index. Note that a CUG cannot be preferential if outgoing calls for that CUG are barred (see the addcug description for the calls-barred information).
Controlling Access for CUG Members
The incoming and outgoing access parameters let you specify access between CUGs for an individual CUG member.
CUG validation takes place at the source and destination of a call. The switch performs CUG validation on CUG calls (calls that contain CUG signaling) and non-CUG (or "normal") calls. This feature complies with source and destination validation as described in Table 3 and Table 4 (respectively) of the ITU-T Q.2955.1 specification. The outgoing and incoming access parameters of this command let you set up a CUG member for source and destination validation.
Outgoing Access
The outgoing access option regulates calls that a CUG member might initiate to members that are outside the CUG. The choices for outgoing access are as follows:
•
•
•
The following example illustrates the role of outgoing access control for CUGs:
1.
2.

Incoming Access
The incoming access option regulates calls that a CUG member might receive from outside the CUG. The choices for incoming access are as follows:

Configure AIS Delay Timer—PXM45, PXM1E
The cnfaisdelaytimer command lets you configure the number of seconds that the node waits to send AIS/Abit toward CPE during user-scheduled SPVC/SPVP grooming. (Re-routing sends AIS/Abit from both ends of a connection when the connection is derouted.) This feature provides a configurable, node-level timer that regulates the time from the moment a connection is intentionally (not accidentally) de-routed to the point when the connection is declared to have failed. If PNNI has not routed the connection when the timer expires, the port sends AIS/Abit.
Route optimization (also called connection grooming) briefly de-routes a connection. On the CLI, the planned route optimization results from either optrte or cnfrteopt operation. To prevent CPE from reverting to back-up facilities, you can delay the transmission of AIS/Abit.

cnfcbclk
Configure Cellbus Clock—PXM45, PXM1E
The cnfcbclk command lets you specify whether a Cellbus runs at the default of 21 MHz or the double-speed rate of 42 MHz. Not every Cellbus (and the card slots it supports) can receive the double-speed clock, so use the dspcbclk to see whether a particular Cellbus can run at 42 MHz. The application of dspcbclk and cnfcbclk is the clocking for the Route Processor Module (RPM). The RPM runs much more efficiently at 42 Mhz.
The backplane has 8 Cellbuses: 6 Cellbuses support 2 card slots and can support 21 MHz or 42 MHz clocking. Two of the Cellbuses (CB4 and CB8) support 6 cards slots and can receive only the 21 MHz clock. See the dspcbclk output in the Example section.

Configure Card Statistics—PXM1E
The cnfcdstat command lets you configure the TFTP bucket statistics for the entire UNI/NNI back card. Parts of the configuration control the bucket interval and the collection interval. These parameters affect the generation of the files that contain statistics and that are transferred to the Cisco WAN Manager (CWM) via FTP.
The card statistics level (stats level) cannot be set if a configuration exists on the lines, such as logical ports. You must set the stats level before you can add any logical ports. However, you can set the bucket interval and the collection interval after you have added logical ports.
Enabling statistics effects performance. Statistical counters use up bandwidth, which reduces the amount of bandwidth available for connections. The PXM1E provides statistical alarms to help control the amount of bandwidth used for statistics.
Statistical alarms are different than integrated alarms. An integrated alarm indicates a persistent traffic loss at either the local end, such as the LOS and LOF alarms, or at the remote end, such as the RDI alarm.
A statistical alarm indicates that a statistical counter has exceeded the threshold for alarm indication. For instance, the Severely Errored Seconds (SES) counter might exceed the corresponding 15-minute threshold. For this condition, a statistical alarm is raised, which indicates a degraded performance that is not due to persistent traffic loss.
Statistical alarms are based on fixed statistics collection intervals. There are two types of fixed statistics collection intervals:
•
•
The start of an interval is aligned to the time of day. For instance, 11:15, 11:30, 11:45, etc. At the end of the interval, the corresponding statistical alarms are cleared. An alarm is raised again if a counter exceeds the threshold during the new interval.

cnfcli
Configure CLI—PXM45. PXM1E
The cnfcli command is the CLI portion of a feature that lets you modify the user privilege (or access) level of one or more commands. The other portions of the feature involve text file creation on a workstation and transferring that file to the switch. For a significant number of commands, you cannot modify the privilege. A list of these commands appears in the section, "Restrictions."
The cnfcli command converts an ASCII text file containing privilege changes to a binary file and applies it to the commands whose privilege you have changed. The ASCII file is created on a workstation by using "vi" or any other text editor. Subsequently, you FTP the file to a TEMP directory on the node.

Configure Clock Source—PXM45, PXM1E
The cnfclksrc command lets you configure a primary or secondary clock source for the node. This command supports the manual clock distribution mode—where the primary and secondary clock sources must be configured at each switch. To enable the automatic clock distribution provided by the Network Clock Distribution Protocol (NCDP), use the cnfncdp command.
Note
A clock source can be:
•
•
•
Clock Operation
When a switch first powers up, the internal oscillator on the PXM provides the clock to the node. Thereafter, you can configure the clock sources at each node according to a well-designed plan for network synchronization.
A typical configuration for a network starts with a Building Integrated Timing System (BITS) clock source of stratum 3 or higher on one of the switches. Therefore, the node with the BITS clock becomes the master clock source for the network. The active clock drives the clock line on the backplane, and each service module takes its clock from this line. Thereafter, the clock goes out through every line to other switches in the network. At the other switches, you can configure one of the lines to be the primary or secondary clock source for that switch.
(For a description of line-level looped timing, refer to the cnfln description. With looped timing, a clock arrives on a line and is redirected to become the transmit clock for only that line.)
Prerequisites to Clock Configuration
Whether it uses BITS or an NNI line for a clock source, the node first must have a network controller. See the addcontroller description. For an NNI-sourced clock, the additional prerequisites are:
•
•
•
Database Updates and Clock Configuration
If the node has a redundant PXM, it automatically receives changes you make to the clock configuration as well as automated clock changes that occur under node management. For example, if you delete a clock source (delclksrc), the standby card automatically implements this configuration change. Also, any switch from primary to secondary source is recorded by the standby PXM.
Syntax
The syntax for cnfclksrc depends on the clock source.
For the external BITS clock:
cnfclksrc <priority> <portid>
portid has the format [shelf.]slot.port -bits e1 | t1 [-revertive <enable | disable>]
For AXSM-sourced clock (note the positions of the periods and colons):
cnfclksrc <priority> <portid>
portid has the format [shelf.]slot:subslot.port:subport or slot.port on a PXM1E
Syntax Description

Changing the Priority of a Clock Source
To change the priority of a clock source, the command sequence depends on the priority of the sources:
•
•
Responses to Clock Failures
If the current clock is the primary or secondary source and that source fails, the clock circuitry goes into holdover mode. Holdover is a standards-based response to a failed clock. In holdover, the UI-S3 card maintains the clock based on the clock signal's parameters as recorded in hardware. Even for a stratum 1 source, the UI-S3 card maintains the frequency and stability of the failed clock source for up to 24 hours. If the source does not return to use in 24 hours, the node switches to the internal oscillator.
Configuring a BITS Clock
You can configure a node to obtain its primary and secondary clocks from a BITS device connected to the PXM-UI S3. The PXM-UI S3 can support stratum levels 1-3 and has two connectors to receive these highly stable clocks from an external device. If the primary and secondary clocks are externally-sourced, they must be the same rate. For example, you cannot specify a T1 for primary and an E1 for secondary.
Note
You can enable a revertive mode for the primary BITS clock. The revertive function on the PXM applies when the primary clock source fails. A failure is a loss of the primary clock source after the node has locked to that clock source. If a primary clock recovers from a failure and revertive mode is enabled, the node automatically reverts to the primary source. The restored primary clock must be available for 12 seconds before it again becomes the active clock source.
If the primary clock source fails and revertive mode is disabled, you must re-configure the primary source after the failure has been corrected.
To change the mode from revertive to non-revertive, use cnfclksrc. Follow the portID and priority with "-revertive disable."

Configure Connection—PXM1E
The cnfcon command lets you modify the bandwidth, policing, and routing parameters of an existing endpoint. On the PXM1E, this command applies to only an SPVC or an SPVP with an endpoint that exists on the network interface (UNI/NNI) back card.The command parameters consist of:
•
•
•
After you specify the mandatory connection identifier, all other parameters are optional.
Usage Guidelines for the cnfcon Command
The following sections discuss the application of certain cnfcon parameters.
Note
Traffic Parameters
Traffic parameters such as PCR, SCR, MBS are entered at both the master and slave endpoints for both the forward and reverse directions when you add the connection. For PCR in the cnfcon command, however, specify lpcr and rpcr at the master endpoint only (the connection manager ignores PCR entries at the slave end for the cnfcon command). Be sure that the value entered as "local" on one end is equal to the value entered as "remote" on the other end. For example, the lpcr on the slave endpoint should be same as the rpcr on the master endpoint and vice versa when you provision the connection at the other end. If you modify traffic parameters after creating an SPVC, you just modify them at either the master endpoint or the slave endpoint.
Traffic parameters such as CDV, CTD are entered at both the master and slave endpoints for both the forward and reverse directions. However, the values of these parameters entered at the slave end are ignored during call setup. Therefore, you can specify the lcdv, rcdv, lctd and rctd options at the master end only.
Routing Parameters
Routing parameter, such as maximum route cost (-mc maxcost) or the routing priority (-rtngprio routingPriority) need to be entered at the master endpoint only. The values of the parameters entered at the slave end are ignored during call setup.
You can assign a priority at the master end of an SPVC or SPVP. The PNNI controller routes higher priority connections before lower priority connections. The user-configurable range for a connection is, in descending order of priority, 1-15. The default is 8. See cnfpri-routing for a detailed description of the Priority Routing feature. Also, the cnfpri-routing command lets you configure groups of bandwidth so that the order of routing also reflects the bandwidth requirements of the connection.
If you use the cnfcon command to modify only the routing priority of a connection, PNNI does not immediately re-route the connection. Nevertheless, if you run dspcon for such a changed connection at the master endpoint, it immediately shows the changed priority even before PNNI re-routes the connection. You can also use the dsppncon command to see the priority of the SVC portion that is associated with master and slave endpoints. Note that the dsppncon command shows the new priority only after PNNI re-routes the connection.
Frame Discard
The current release supports two types of frame discard for VCCs carrying AAL5 cells. These frame discard mechanisms are policing-based and congestion-based. Policing-based frame discard depends on the -frame option in the addcon or cnfcon command. (Congestion-based policing for all cell streams is governed by settings in the current port SCT.) This -frame parameter is specified only at the master end.
When policing-based frame discard is enabled, the policer discards all cells of an AAL5 frame that follow a non-compliant cell. Specific actions for PCR and SCR non-compliance are detailed in the section, "Policer Settings and Consequences."
When congestion based frame discard is enabled in the current port-level SCT, if the arriving cells exceed an EPD threshold, the whole frame is discarded.
The table below shows the action applied to a connection according to the frame discard setting. The following information clarifies the table contents:
•
–
–
•
–
–
Restrictions
Frame discard applies to connections that use ATM AAL5 adaptation (ITU-T I.363.5). Although enabling frame discard on an AAL5 cell stream is not mandatory, it helps improve the useful throughput on a VC by discarding complete frames during times of congestion on the switch. Without frame discard enabled on an AA5 cell stream, corrupted AAL5 frames (containing dropped cells) can reach upper layers and trigger numerous re-sends. Conversely, enabling frame discard on other (non-AAL5) types of cell streams can bring uncertain results. In a worst case, total discard of end-to-end traffic of a non-AAL5 stream can occur in either direction.
The hardware does not support frame-based discard on VPCs. Only VCCs support frame-based discard.
Note
Policer Settings and Consequences
This section describes two types of conformance tests that occur when you enable frame discard through this frame discard parameter. The tests are PCR and SCR conformance tests.
The PCR conformance test is performed using GCRA1 in exactly the same manner as normal cell policing. For this test, the Action should be set to discard. If the PCR conformance test is deemed to be non-compliant, the action will be to discard of the cells in the current frame. In other words, a "partial packet action" can be taken when cells in the current frame fail this conformance test. The PCR conformance test implements a partial packet discard (PPD). The policer does a complete frame discard if the first cell of the packet was discarded as a result of PCR failure
The SCR conformance test is performed using GCRA2, although it differs slightly from the normal cell policing.The SCR conformance test is performed only at the start of a frame. If the first cell of a frame is a conforming CLP=0 cell, then all remaining cells will be as if they are conforming to the SCR conformance test. The SCR conformance test can be programmed to tag non-conforming CLP=0 cells. If the first cell of a frame is a non-conforming CLP=0, then that cell and all other cells in that frame (including the EOM) will be tagged. In other words, the tagged action taken by this conformance test is determined at frame boundaries only. If the SCR conformance test is programmed to discard, the policer can discard at any point in the frame and is not restricted by frame boundaries.
Local-Only Parameters
The parameters CDVT, stats enable, cc enable (specified using -cdvt, -stat, -cc) are significant only at the endpoint where you enter them. Therefore, they can be different at each end of the connection.

•
-lpcr
Local peak cell rate (PCR). Specifies the PCR from a local endpoint to a remote endpoint (3-5651328 cells per second). PCR is the maximum cell rate for the connection at any time.
Note
-rpcr
Remote peak cell rate (PCR). Specifies the PCR from a remote endpoint to a local endpoint (3-5651328 cells per second). PCR is the maximum cell rate for the connection at any time.
Note
-lscr
Local sustained cell rate (SCR). Specifies the SCR from a local endpoint to a remote endpoint (3-5651328 cells per second). SCR is the maximum cell rate that a connection can sustain for long periods.
-rscr
Remote sustained cell rate (SCR). Specifies the SCR from a remote endpoint to a local endpoint (3-5651328 cells per second). SCR is the maximum cell rate that a connection can sustain for long periods.
-lmbs
Local maximum burst size (MBS). Specifies the MBS from a local endpoint to a remote endpoint (1-5000000 cells). MBS is the maximum number of cells that can burst at the PCR and still be compliant.
-rmbs
Remote maximum burst size (MBS). Specifies the MBS from a remote endpoint to a local endpoint (1-5000000 cells). MBS is the maximum number of cells that can burst at the PCR and still be compliant.
-cdvt
Local cell delay variation tolerance (CDVT). Specifies the CDVT from a local endpoint to a remote endpoint (1-5000000 microseconds). Cell Delay Variation Tolerance controls the time scale over which the PCR is policed.
Note that no remote CDVT is necessary.
-lcdv
The local cell delay variation (CDV) parameter specifies the peak to peak CDV from the local endpoint to the remote endpoint. The range is 1-16777215 microseconds.
To revert to the default value for this parameter, type "-1."
-rcdv
The remote cell delay variation (CDV) parameter specifies the peak to peak CDV from the remote endpoint to the local endpoint. The range is 1-16777215 microseconds.
To revert to the default value for this parameter, type "-1."
-lctd
Local cell transfer delay (CTD). This parameter specifies the CTD from a local endpoint to a remote endpoint. The range is 0-65535 milliseconds.
To revert to the default value for this parameter, type "-1."
-rctd
Remote cell transfer delay (CTD). This parameter specifies the CTD from the remote endpoint to the local endpoint. The range is 0-65535 milliseconds.
To revert to the default value for this parameter, type "-1."
-cc
Operations, administration, and maintenance continuity check (OAM CC):
•
•
Continuity checking involves a round trip of an OAM cell simply to confirm that both directions of the connection are intact.
To provision continuity checking, enable this function at both ends of the connection, otherwise a connection alarm results. When you add a connection and include this parameter, the connection goes into alarm until both ends of the connection are added.
Note that a non-zero AIS delay timer affects CC functionality (if enabled) during the intentional re-routing of a connection following the optrte or cnfrteopt command. (See the cnfaisdelaytimer description for details of this AIS-delay feature.) If the delay timer is configured and the connection is groomed, the switch turns of CC until the connection is re-routed.
Default: 0
-stat
Statistics collection: enter 1 to enable or 0 to disable. The default is 0.
The Cisco WAN Manager tool collects statistics for a connection if you enable it here. Statistics collection is disabled for all connections by default. Statistics collection has an impact (which may not be significant) on the real-time response, especially for SVCs (which can be affected even though you do not add SVCs). Therefore, you should enable statistics collection for only the subset of connections that really warrants such a feature.
-frame
This option lets you enable or disable frame-based policing and discard for the VCC (no VPCs). See the section, "Frame Discard," for more details on frame discard.
Note
Possible values:
•
•
Default: 0 (disabled)
-mc
Maximum cost (maxcost): a value that creates a priority for the connection route. The switch can select a route if the cost does not exceed maxcost. The range for maxcost is 0-4294967295. If you do not specify maxcost, the connection has the highest routing priority by default. Therefore, the maxcost parameter lets you lower the routing priority of a connection. Note the following effects of values in the maxcost range:
•
•
•
Although maxcost applies to an individual connection, routing costs substantially depend on a cost-per-link that you specify at every PNNI logical port in the network. The applicable PNNI command is cnfpnni-intf.
The cost of a route is as follows:
routing cost=sum of all costs-per-link
where:
•
•
The cost-per-link applies to all connections of a particular service type on a port. For example, the cost-per-link is the same for all VBR.1 connections that PNNI controls on a port, and this cost can differ from all UBR.1 connections on the same port. Alternatively, you can use cnfpnni-intf to make the cost-per-link the same for all service types.
To illustrate by examining a four-link route:
1.
2.
3.
The route is usable because the cost of 50240 is less than the maxcost of 100000.
Default: 4294967295 The default makes maxcost meaningless for the connection, so PNNI does not use it as a routing metric.
Note
-lputil
Local Percentage Utilization: Range 1-100. The default is 100.
-rputil
Remote Percentage Utilization: Range 1-100. The default is 100.
-rtngprio
You can modify the priority of this connection. The descending range of priorities is 1-15. The default is 8. See the cnfpri-routing description for details on this feature.
-prefrte
This option modifies the preferred route association to the connection. Use this optional parameter at the master endpoint only. See the addpref description for details about the preferred route feature.
To disassociate a connection from a route, type a 0 for this parameter.
Note
Range: 0-65535
Default: 0
-directrte
This parameter specifies whether the connection can take only the preferred route associated through the -prefrte parameter. Use this optional parameter at the master endpoint only. To remove the directed route requirement from the connection, specify a 0 for this parameter. The possible values are as follows:
•
•
Default: no (0)

Configure Connection Segment Endpoint—PXM45, PXM1E
The cnfconsegep command lets you configure a segment endpoint for an SVC or SVP on a via node. Its purpose is to support a particular troubleshooting scheme. After you create an endpoint, you can use the tstdelay command and specify the endpoint created with the cnfconsegep command. The Example section shows how to use tstdelay and conntrace in conjunction with the cnfconsegep command.
You can specify more than one endpoint as long as each one complies with the requirements of the cnfconsegep command, as follows:
•
•
•
In Figure 2-5, an SPVC has endpoints at UNI1 and UNI12. You can use cnfconsegep to configure segment endpoints at NNI2, NNI3, NNI4, and NNI5. You cannot configure segment endpoints at UNI1, UNI12, NNI1, and NNI6. After you configure any of these endpoints, you could verify the electrical integrity by using the tstdelay command from UNI1 or UNI12 to each of NNI2, NNI3, NNI4, or NNI5. After you finish troubleshooting, remove all segment endpoints by using delconsegep for each endpoint.

From the PNNI physical port ID 9:1.8:8, you know to cc to slot 9 and specify ifNum 8. (Note that Cisco does not recommend using the tstdelay command for acquiring an accurate measurement of the round trip delay. Its function is better suited to confirming the existence of the connection path.)

Note that the round trip delay is significantly longer (194 microseconds compared to 128 microseconds in the first instance). If the OAM cells did not return to the near end, the segment where traffic was being lost would have been identified.
Also note that the configuration of segment endpoints can occur on many via nodes.

Configure Diagnostics—PXM45, PXM1E
The cnfdiag command enables either the on-line or off-line diagnostics. It also lets you configure the settings for the start time and coverage for running the off-line diagnostics. This system blocks any attempt to apply this command to an empty slot or an unsupported card.
The cnfdiagall command is the same as cnfdiag except that it configures all slots on the card at once.
Note
The Purpose of the Diagnostics
The diagnostics configured by the cnfdiag command test and validate the communication paths or devices on the PXM and the service modules during periods of operation or non-operation (on-line or off-line, respectively). The diagnostics are always scheduled from the PXM controller card whether they run on the PXM or a service module.
The PXM45 has a backward-compatibility requirement to support service modules that transport ATM cells over the Cellbus. (The PXM1E supports only Cellbus-based cards and so does not have this backward compatibility issue.) The PXM45 transport ATM cells over the following two buses:
•
•
Because of the difference between bus speeds on the backplane, the Reliability Availability Serviceability (RAS) requirements demand that diagnostics periodically run on the communications paths. Therefore, diagnostics should periodically run on both active and standby cards—especially on standby cards. Frequent testing of standby cards through diagnostics helps to ensure that when an active card fails, the standby card is ready to take the active card role immediately.
On-line Diagnostics
On-line diagnostics are nondestructive tests (that do not interfere with live traffic) and run on either an active card or a standby card. The MGX 8950, MGX 8850, and MGX 8830 switches support various on-line diagnostics tests. The sections that follow describe the tests that run on a PXM45 or PXM1E.
Off-line Diagnostics
Off-line diagnostics are destructive (interfere with traffic) and therefore run only on standby cards. These diagnostics are scheduled by using the off-line start (offStart) and off-line day-of-week (offDow) parameters. The coverage (offCover) parameter specifies the length of time that the diagnostics run.
Note
The off-line diagnostics that can be enabled and scheduled depend on the circuitry. The sections that follow list the off-line diagnostic by card.

If the cards are out of the backplane and power is off, just install the front cards. An SRM with no back card appears in card displays as "SRM_NO-BC.)Generic Syntax
This section introduces general information about the syntax. The syntax varies according to the line type, so each line type has its own description.
Your entries for line type and slot number determine the option list for cnfln on a PXM. The options for line type depend on whether the line is SONET, SDH, T3, E3, E1, or T1. The slot indicates to the controller whether the card is an SRM or the PXM1E network interface card. The generic syntax follows:
cnfln -<lineType> slot.line <optionList>
If you enter only the line type, slot number, and line number, the Help feature displays appropriate syntax with option list. In the sections that follow, the Syntax and Syntax Description heading shows the line type.
To help you enter the correct line type and to locate the SRMs, use some of the high-level commands. To see all cards in the switch, use the dspcds command. The display shows where and what type of SRMs are present. To see the type of PXM1E back card, use the dspcd command on the PXM1E CLI. To see the types for all lines, use the dsplns command.

Configure Maximum Burst Size Default—PXM45, PXM1E
Configures the default maximum burst size (MBS) for SPVCs on a port. The applicable service types are real-time and non real-time variable bit rate (rt-VBR and nrt-VBR).
The most likely connection type for which you would use cnfmbsdft is SVC. You can also rely on the value set with this command as a default for SPVCs if you do not specify an MBS through addcon for each SPVC of service type VBR.
The new configuration applies to new incoming calls, not existing calls. You can use cnfmbsdft whether the port is active or in the provisioning state.

Configure NCDP—PXM45, PXM1E
The cnfncdp command lets you change the clock distribution mode at the switch level. The choices are manual mode and Network Clock Distribution Protocol (NCDP). At every switch that you plan to use NCDP, you must enable it through the cnfncdp command. (See Syntax and Syntax Description for the optional parameters.) A switch can use only one distribution mode, and the default mode is manual. The unused mode is disabled. Normally, if you enter a command that applies to the mode that is disabled, the controller rejects the command. Although the two modes are mutually exclusive, the configuration for each mode is saved. If you return a switch to its previous distribution mode, the previous configuration is operational.
Note
For manual clock distribution, use cnfclksrc and related commands to modify, view, or delete clock sources. If you upgrade from Release 2.1 to Release 3 or later software, the switch comes up in manual clock distribution mode and has the previous configuration for manual distribution.
Note
The manual and NCDP modes require some configuration at each switch. Regardless of the mode, a switch can synchronize to any of the following:
•
•
•
If you select NCDP, the optional cnfncdp parameters let you configure as needed the following values:
•
•
•
•
Note
NCDP synchronizes each switch to a single root (or master) clock reference. When you first enable NCDP on more than one switch, it automatically selects the oscillator on one of the switches to be the root of a network clock spanning tree. (On the other hand, if you have pre-configured an external source, NCDP becomes enabled with that source.) When you further configure clock source priorities and a possible BITS device, NCDP again identifies the best source according to your parameter entries.
With each change in NCDP clock state—such as node reset or introduction of a BITS device—it uses the values in the following hierarchy to select a root.
1.
2.
3.
4.
After NCDP determines the default root clock source, it identifies that root to every node in the network.
NCDP ensures that all nodes have a record of the entire spanning clock tree. Thus, each node has a record of the node with the root (or "best") clock source and gets its root source from that node. The maximum number of hops to that master clock node is configurable.
The default clock source under NCDP—a free-running, internal oscillator—is sufficient for a small network. However, the concept of the "best" clock source actually becomes meaningful when you connect a BITS clock or define clocking domains.
Note
To create clocking domains or to configure a BITS clock, NCDP provides the following commands:
•
•
•
–
–
–
Syntax
cnfncdp [ -distributionMode {ncdp | manual] [-maxNetworkDiameter hopcount]
[-hello milliseconds] [-holdtime milliseconds] [-topoChangeTimer milliseconds]Syntax Description
If the distribution mode is manual, only the -distributionMode parameter is meaningful. If you enable NCDP, all other parameters become meaningful.

Configure NCDP Clock Source—PXM45, PXM1E
The cnfncdpclksrc command lets you configure clock sources so that NCDP selects the clock source you want to serve as the best (or root or master) source. The primary use of this command is for specifying external clock sources. To do so, you indicate a high priority and stratum level for the external source. NCDP uses these values to determine the best clock source in the network and build the spanning clock tree. An external source can be a Building Integrated Timing Source (BITS) device connected to a PXM or—much less commonly—a UNI port somewhere on the switch.
Note
External Clock Sources
Even with external sources, you do not need to use the cnfncdpclksrc command at each node (although you must enable NCDP at each node by using the cnfncdp command). You can specify a small number of external sources and, if desired, one or two internal sources as backup for unlikely failure scenarios and leave it to NCDP to utilize the priorities as needed. If every configured source were to fail—leaving all internal oscillators in the network with the same priority—NCDP would use the ATM address of each node as a tie-breaker to select and propagate a root clock.
Internal Clock Sources
You can direct NCDP to select the internal oscillator of a particular node as the root for the following reasons:
•
•
NCDP chooses a node as the best source whether or not you assign a priority to an internal clock. NCDP uses its usual hierarchy of values in the following list to pick a node as the root. In the case of an internal source, the pertinent values are priority and nodal ATM address, as the annotations in the list state:

Operational Details of the cnfncdpclksrc Command
The cnfncdpclksrc parameters let you specify the following values:
•
•
•
•
•
The only ports you can specify with the cnfncdpclksrc command are those of an external device or a UNI (see the syntax description for port details). You do not specify an NNI as a source, yet NCDP on each node may determine that its root clock comes through an NNI. If a node receives its root clock source through an NNI based on the protocol's calculations, the dspncdpclksrcs output reveals this fact. With NCDP enabled at the node level by the cnfncdp command, all NNI ports are enabled to support NCDP. (On a per-port basis, you can disable NCDP by using the cnfncdpport command.)
Displaying NCDP Clock Sources
The dspncdpclksrcs command identifies where the current node receives its clock. This command applies to only the node where you run it. If the local node is not the source of the best clock according to NCDP, the dspncdpclksrcs output shows the NNI port that is the node's timing source. No command searches the whole network and shows where the master clock originates. To find the source if it was not recorded, you would have to telnet to each node and run dspncdpclksrcs. Therefore, record the sources you configure with the cnfncdpclksrc command. For more details, see the section, "Usage Guidelines for the cnfncdpclksrc Command."
How NCDP Chooses the Root Clock Source
The root clock source is the root of the spanning tree for the clocking domain. Under NCDP control, clock source data in configuration PDUs from each node spread throughout the network. Using the information propagated by the configuration PDUs, NCDP builds a spanning network clock tree. Note that NCDP determines the root clock source based on information you provide. A derivative of the spanning tree algorithm and protocols specified in ANSI/IEEE Standard 802.1d are used to construct the network clock spanning tree. If you provide no information, NCDP selects a root based on a sequence of possible tie-breakers.
NCDP can rely on the clock priority alone to determine the root clock source. As needed, NCDP uses the following hierarchy of criteria for finding the root clock source. For example, if 1, 2, and 3 in the following list are the same throughout the clocking domain, the ATM address (4) serves as tie-breaker:
1.
2.
3.
4.
Convergence is reached when all switches using NCDP have received PDUs with the clock configuration values from the total number of switches equal to the maximum-length clocking path. (The maximum clocking path is the largest number of hops between any two switches in the clocking domain. This value is configurable through the cnfncdp command.) Upon convergence, NCDP determines the root clock source and builds the spanning tree.
How NCDP Propagates the Root Clock
This sections introduces how NCDP uses NNI ports for propagating the best clock.
In Figure 2-6, Node 1 has a BITS device that has an assigned clock priority of 1, so it has the highest priority of all NCDP sources in the network and is therefore the root. Node 1 transmits its clock through two NNI ports (1a and 1b) to Node 2. Node 2 chooses port 2a as its root clock source because port 2a has a lower numerical significance then port 2b. (Node 2 also has a BITS device, but its priority is 10, making it the back-up clock source in case the root clock source becomes unavailable.) In the same way, Node 3 and Node 4 receive and pass on the best clock.

Configure Node Parameters—PXM45
The cnfndparms command lets you configure a diverse set of node-level parameters.
Note
The parameters consist of an option number and a value or a yes/no choice. The configuration resides in non-volatile RAM and thus survives a system reset or power cycle. Due to the wide range of options and the possible values assigned to these options, the sections that follow describe each option and later describe the values you can assign (a hexadecimal number, a yes or no entry, and so on).
To see the current configuration for these parameters, use the dspndparms command. For information on the alarms that may relate to the parameters, see dspndalms and dspenvalms.
Maximum Card Resets
The first two options are a window (in seconds) for counting resets and a number of resets. The combined purpose of these parameters is to prevent an endless loop of card resets.

Shutting Off Alarms for Absent Core Cards
This option lets you specify whether a redundant core card that is removed from the backplane causes an alarm. (The core cards are the PXMs and SRMs.) The purpose of this option is to let you turn off alarms when the node configuration shows core card redundancy but one card stays out of the backplane for an extended period of time. The purpose is to let you turn off alarms until you re-install the card.
Enable Expanded Memory for 250K Connections
This option lets you enable expanded memory on the PXM45 to support 250K connections. To enable expanded memory, a pair of PXM45/Bs or PXM45/Cs must reside in the system.
Caution
Required Power Supply Module Bitmap
This option lets you specify the locations of required power supplies in an AC-powered system. If any one of the required supplies is removed, an alarm results. (See also the descriptions of dspndalms and dspenvalms regarding alarms.) Additional supplies can also exist in the power supply tray, but removing one of the additional supplies does not cause an alarm.
An AC power supply tray holds six power supply units (PSUs). (Refer to the hardware installation guide for details.) A supply belongs to one of two groups: A1-A3 or B1-B3. An 8-bit hexadecimal number identifies an individual supply. The value is the sum of any combination of hexadecimal numbers. For example, the value for requiring A1 and B1 is:
0x01 + 0x10 = 0x11
Required Fan Trays
This option lets you specify required fan trays for the purpose of alarm generation. You can specify either or both fan trays as required. The value is an 8-bit hexadecimal number.
Note
•
•
•
To require top and bottom fan trays, for example, enter a hexadecimal 3 for the option value:
0x01+0x02=0x03
Trap Manager Aging Timeout
This option lets you specify the number of hours that a trap manager can age before the switch deletes that trap manager's registration. This node-level setting applies to all registered trap managers. The default of 0 means that the registration of trap managers on the switch do not age. The only applicable trap managers for this parameter are Cisco WAN Manager (CWM) workstations.
The application of a non-zero aging parameter is an environment where the IP address of the network management stations are likely to change or where the workstations themselves are likely to be moved. Non-CWM users or managers of a stable network manager environment should leave the setting at zero.
Primary IP Interface for Network Management
This option lets you specify a primary interface type for discovery by CWM. The main purpose is to let you change from the default ATM interface to a LAN interface for use by CWM. The context of the LAN choice is where you want to build an IP connectivity infrastructure for CWM by using LAN interfaces. After specifying a LAN interface, CWM discovers this type while doing an ILMI MIB-walk.
Secondary IP Interface for Network Management
This option automatically enables CWM to learn the secondary IP interface by doing a MIB-walk and reading the PNNI topology state element table. If you do not enable this feature, the PTSEs do not flood the secondary IP address.
Automatic Setting of Cellbus Clock Speed for RPM
This option lets you enable the automatic setting of Cellbus clock speeds for the Route Processor Module-Premium (RPM-PR). If you enable this feature, the switch automatically adjusts the Cellbus clock as needed when you insert or remove an RPM-PR at a particular Cellbus. If this feature is enabled, for example, and two RPM-PRs are plugged into a Cellbus, the clock speed is 42 MHz. If you remove one RPM-PR, the clock drops to 21 MHz.
The Cellbus clock rates must be correct for the RPM-PR to do traffic shaping. If clock-setting is not automatic, you would have to adjust clock speeds by using the cnfcbclk command. To see whether automatic or manual clock setting is enabled, use the dspcbclk command.
If you turn on this feature and one or more AXSMs is running at 42 MHz, the clock for all such AXSMs immediately becomes 21 MHz regardless of how many AXSMs reside in the switch.
Inband Node-to-Node IP Connectivity
This option lets you enable or disable inband, node-to-node IP connectivity so you can telnet from the CLI of one switch to the CLI of another switch.
After you telnet, an SVC is set up between the local node and the remote node. (The SVC is the transmission medium for all IP traffic between two nodes, yet the SVC and telnet are independent of each other: the telnet is just one kind of traffic.) If you disable this feature after the SVC is created then proceed to transfer more IP data between nodes, the transfer of IP data is successful. In fact, it works without disruption until the SVC is torn down. Note that the SVC is torn down when no IP traffic traverses the SVC for 15 minutes.
To exit the CLI of the remote switch—to break the connection and terminate the telnet session—enter the exit or bye command. See Examples section for this feature.
This parameter is enabled by default after you run the clrallcnf command. On the other hand, if you upgrade from a software release that does not have this parameter, the default state is disabled.
PXM Switchover on Back Card Mismatch
When enabled, this option causes a switchover of redundant PXMs if the incorrect, field-replaceable back card (FRU) is inserted. The existence of various models of the PXM45, variations in the PXM1Es, and two models of the user interface (UI) back card have led to the creation of an option that lets you specify that if the incorrect combination is detected, the redundant pair switches over. See for the supported and disallowed combinations. The "yes" indicates a supported combination, and the "no" indicates a mismatched combination.
Disabling the High Priority LCN for Inter-Process Communication
The switch reserves two logical connection numbers (LCNs) for inter-process communication (IPC)—in this instance, the communication between applications on different cards. One LCN carries low-priority messages, and the other LCN carries high-priority (urgent) messages. By default, both priorities of LCN are available, and the cards select the priority for messages as needed.
This option lets you disable the high-priority LCN so that the applications exchanges all messages on the low priority LCN.
Option Values
This command requires various number formats to support its parameters, as follows:
•
•
•
•

Each option description states the type of number involved and the actual range for that option. Alternatively, the description states if the choice is "yes" to enable of "no" to disable.

A number that selects the option. Refer to the description of each option at the beginning of this description for important details and warnings.
Range: 1-14
Option 1
Option 1 is the number of seconds to count the resets of the shelf management cards. The range is 0-65355 (a 16-bit decimal number). The default is 3600 seconds (1 hour). A 0 means an infinite time period. The impact of an infinite time period is that only a specified count of resets can stop the resets.
Option 2
This option lets you set the maximum number of resets of the shelf management card group per time period. (The time period is specified through Option 1.) The number is an 8-bit decimal number and therefore has the range 0-255. The meaning of a 0 for this parameter is an infinite number of resets—the resets can continue without end.
Default: 3 resets per period.
Option 3
This option lets you enable or disable core card redundancy. Enter "yes" to enable or "no" to disable alarms on a missing, redundant core card. The default is enable, which means an alarm appears in the absence of a redundant core card.
Option 4
This option lets you enable or disable expanded memory on the PXM45/B or PXM45/C to support 250K connections. Enter "yes" to enable or "no" to disable The default is no. Once enabled, this option cannot be disabled—even by the clrallcnf command.
Option 5
This option you specify the locations of required power supplies in an AC-powered system. The number is 8-bit hexadecimal:

Default: yes
Option 11
This option lets you enable inband, node-to-node IP connectivity so you can telnet between this CLI and other switches where this feature is enabled. Type "yes" to enable or "no" to disable.
Default: enabled
Option 12
This option is reserved for future use. 0 No Gang, 1 Left, 2 Right, 3 Both Gang Present
Option 13
This option enables automatic switch-over when a FRU back card mismatch occurs. Type a 1 to enable or a 0 to disable this feature. This choice relates to the combinations of controller card models and the user interface (UI) back card. Refer to the section, "PXM Switchover on Back Card Mismatch," for information on the combinations.
Default: 0 (disabled).

Configure Node Parameters—PXM1E
The cnfndparms command lets you configure a diverse set of node-level parameters.
Note
A Syntax Description for each chassis type due to a difference in available parameters.The parameters consist of an option number and a value or a yes/no choice. The configuration resides in non-volatile RAM and thus survives a system reset or power cycle. Due to the wide range of options and the possible values assigned to these options, the sections that follow describe each option and later describe the values you can assign.
To see the current configuration for these parameters, use the dspndparms command. For information on the alarms that may relate to the parameters, see dspndalms and dspenvalms.
Maximum Card Resets
The first two options are a window (in seconds) for counting resets and a number of resets. The combined purpose of these parameters is to prevent an endless loop of card resets.

Shutting Off Alarms for Absent Core Cards
This option lets you specify whether a redundant core card that is removed from the backplane causes an alarm. (The core cards are the PXMs and SRMs.) The purpose of this option is to let you turn off alarms when the node configuration shows core card redundancy but one card stays out of the backplane for an extended period of time. The purpose is to let you turn off alarms until you re-install the card.
Required Power Supply Module Bitmap
This option lets you specify the locations of required power supplies in an AC-powered system. If any one of the required supplies is removed, an alarm results. (See also the descriptions of dspndalms and dspenvalms regarding alarms.) If you remove a power supply not identified as a required supply, no alarm is triggered.
An AC power supply tray holds six power supply units (PSUs). (Refer to the hardware installation guide for details.) A supply belongs to one of two groups: A1-A3 or B1-B3. An 8-bit hexadecimal number identifies an individual supply. The value for this option can be the sum of any combination of hexadecimal numbers. For example, the value for requiring A1 and B1 is:
0x01 + 0x10 = 0x11
Required Fan Trays
This option lets you specify required fan trays for the purpose of alarm generation. You can specify either or both fan trays as required. The value is an 8-bit hexadecimal number.
Note
An MGX 8830 chassis has only one fan tray, so this option is not available on the MGX 8830 chassis.•
•
•
To require top and bottom fan trays, for example, enter a hexadecimal 3 for the option value:
0x01 + 0x02 = 0x03
Trap Manager Aging Timeout
This option lets you specify the number of hours that a trap manager can age before the switch deletes that trap manager's registration. This node-level setting applies to all registered trap managers. The default of 0 means that the registration of trap managers on the switch do not age. The only applicable trap managers for this parameter are Cisco WAN Manager workstations.
The application of a non-zero aging parameter is an environment where the IP address of the network management stations are likely to change or where the workstations themselves are likely to be moved. Non-CWM users or managers of a stable network manager environment should leave the setting at zero.
Primary IP Interface for Network Management
This option lets you specify a primary interface type for discovery by Cisco WAN Manager. The main purpose is to let you change from the default ATM interface to a LAN interface for use by CWM. The context of the LAN choice is where you want to build an IP connectivity infrastructure for CWM by using LAN interfaces. After specifying a LAN interface, CWM discovers this type while doing an ILMI MIB-walk.
Secondary IP Interface for Network Management
This option automatically enables Cisco WAN Manager (CWM) to learn the secondary IP interface by doing a MIB-walk and reading the PNNI topology state element table. If you do not enable this feature, the PTSEs do not flood the secondary IP address.
Automatic Setting of Cellbus Clock Speed for RPM
This option lets you enable the automatic setting of Cellbus clock speeds for the Route Processor Module-Premium (RPM-PR). If you enable this feature, the switch automatically adjusts the Cellbus clock as needed when you insert or remove an RPM-PR at a particular Cellbus. If this feature is enabled, for example, and two RPM-PRs are plugged into a Cellbus, the clock speed is 42 MHz. If you remove one RPM-PR, the clock drops to 21 MHz.
The Cellbus clock rates must be correct for the RPM-PR to do traffic shaping. If clock-setting is not automatic, you would have to adjust clock speeds by using the cnfcbclk command. To see whether automatic or manual clock setting is enabled, use the dspcbclk command.
Inband Node-to-Node IP Connectivity
This option lets you enable or disable inband, node-to-node IP connectivity so you can telnet from the CLI of one switch to the CLI of another switch.
After you telnet, an SVC is set up between the local node and the remote node. (The SVC is the transmission medium for all IP traffic between two nodes, yet the SVC and telnet are independent of each other: the telnet is just one kind of traffic.) If you disable this feature after the SVC is created then proceed to transfer more IP data between nodes, the transfer of IP data is successful. In fact, it works without disruption until the SVC is torn down. Note that the SVC is torn down when no IP traffic traverses the SVC for 15 minutes.
To exit the CLI of the remote switch—to break the connection and terminate the telnet session—enter the exit or bye command. See Examples section for this feature.
This parameter is enabled by default after you run the clrallcnf command. On the other hand, if you upgrade from a software release that does not have this parameter, the default state is disabled.
PXM Switchover on Back Card Mismatch
When enabled, this option causes a switchover of redundant PXMs if the incorrect, field-replaceable back card (FRU) is inserted. The existence of various models of the PXM45, variations in the PXM1Es, and two models of the user interface (UI) back card have led to the creation of an option that lets you specify that if the incorrect combination is detected, the redundant pair switches over. See for the supported and disallowed combinations. The "yes" indicates a supported combination, and the "no" indicates a mismatched combination.
Disabling the High Priority LCN for Inter-Process Communication
The switch reserves two logical connection numbers (LCNs) for inter-process communication (IPC)—in this instance, the communication between applications on different cards. One LCN carries low-priority messages, and the other LCN carries high-priority (urgent) messages. By default, both priorities of LCN are available, and the cards select the priority for messages as needed.
This option lets you disable the high-priority LCN so that the applications exchanges all messages on the low priority LCN.

Configure Resource Partition—PXM1E
The cnfpart command lets you modify the bandwidth and other resource partitioning on a logical port. The entity that makes use of the resources in a partition is a network controller. For many partition parameters, you can dynamically make modifications—without administratively downing the port—by using the cnfpart or cnfrscprtn command. However, before you can modify the minimum or maximum VPI or VCI, the port must be down.
The existing controllers are the Private Network to Network Interface (PNNI) and the Label Switch Controller (LSC). In the current release of the PXM1E, only PNNI is supported. Before you add a resource partition, have a plan for future changes, such as the support of a new controller.
A resource partition consists of:

Note
Ports, Partitions, Controllers, and Interface Types
This section contains details regarding ports, partitions, and controllers that you should note before adding a partition.
On each port—regardless of the interface type—a controller can have one partition. Therefore, on a port, you can add one partition for PNNI and one for LSC (but keep in mind that the PXM1E currently uses only PNNI). This requirement applies regardless of whether an interface (specified through addport) is UNI, NNI, VUNI, or VNNI.
The pairing of partition ID and controller ID must be the same across all interfaces. In this situation, the interface number uniquely identifies the partition. For example, on a PXM1E-4-OC3 with two UNIs and two NNIs, you could specify:
•
•
•

The VPIs and VCIs you modify with the cnfpart command must be within the range specified when the port was created through the addport command,
