Introduction

CTM is an advanced management system that provides functionality at the element and network management levels for Cisco network elements (NEs), routers, and switches. CTM supports fault, configuration, performance, and security management functional areas. CTM also serves as a foundation for integration into a larger overall operations support system (OSS) environment by providing northbound gateway interfaces to higher-layer management systems.

CTM supports data service provisioning over ML-series cards. Data service provisioning consists of provisioning the Layer 2 topology using optical circuits, and then provisioning the Layer 2 service on top of the Layer 2 topology.

Alarm notification and performance monitoring features on data cards (ML-series cards) are SNMP-based. To allow CTM to support alarm and event notification and performance monitoring on data cards, the SNMP trap forwarding mechanism must be set up on each node of the data card.

This document provides the set of Cisco IOS commands issued by CTM during Layer 2 topology and Layer 2 service provisioning. The syntax used for the commands must be respected for services provisioned directly using Cisco IOS so that the provisioned services are recognized by CTM.

SNMP Trap Destination Setup

For the cards to have full CTM support, the SNMP trap destination must be set up for each node where there is a data card inserted:

•The NE containing the ML-series card must have a valid SNMP community string. If the SNMP community string is not valid, a resynchronization failure occurs and is logged in the Audit Log.

•The Cisco IOS startup-config file must contain the snmp-server enable traps command to receive traps from ML-series cards. See Overview for more information.

•You must force resynchronization on the NE by marking it as Out of Service (OOS), and then back In Service (IS) when you change the trap destination in either Cisco Transport Controller (CTC) or CTM. This operation forces the registration of ML-series cards for traps.

•You must set up the trap destination based on the SNMP version (SNMPv1 or SNMPv2) and the gateway NE/end NE (GNE/ENE) configuration of the node. Set the trap destination in the NE Explorer window (see Figure 1).

Figure 1 NE Explorer Window—SNMP Trap Destination Setup

The following table lists the possible SNMP configurations.

Table 1 SNMP Configurations 

Node Setup	Allow SNMP Set	Use Generic MIB	Allow SNMP Proxy	IP Address	Community Name	UDP Port	Trap Version	Relay A IP Address
SNMPv1—NE R7.0 and later
GNE	Enable	Enable	Enable	CTM server IP address	Public	162	SNMPv1	—
ENE (with relay)	Enable	Enable	Enable	CTM server IP address	Public	162	SNMPv1	Active GNE's IP address
ENE (without relay)	Enable	Enable	Enable	GNE IP address	Public	391	SNMPv1	—
SNMPv2—NE R7.0 and later
GNE	Enable	Enable	Enable	CTM server IP address	Public	162	SNMPv2	—
ENE (with relay)	Enable	Enable	Enable	CTM server IP address	Public	162	SNMPv2	Active GNE's IP address
ENE (without relay)	Enable	Enable	Enable	GNE IP address	Public	391	SNMPv2	—
SNMPv1—NE releases earlier than R7.0
GNE	Enable	Enable	Enable	CTM server IP address	Public	162	SNMPv1	—
ENE (with relay)	Enable	Enable	Enable	CTM server IP address	Public	162	SNMPv1	Active GNE's IP address
ENE (without relay)	Enable	Enable	Enable	GNE IP address	Public	391	SNMPv1	—
SNMPv2—NE releases earlier than R7.0
GNE	Enable	Enable	Enable	CTM server IP address	Public	162	SNMPv2	—
ENE (with relay)	Enable	Enable	Enable	CTM server IP address	Public	162	SNMPv2	Active GNE's IP address
ENE (without relay)	Not supported.

When setting up an SNMP trap destination:

1. Delete the GNE and ENE's SNMP trap destinations before performing GNE-ENE role changes. After a GNE-ENE role switch is complete, add the new SNMP trap destinations according to the new GNE-ENE roles.

2. If the ENE does not contain the GNE's SNMP community string, mark the ENE as Out of Service and then In Service.

3. Do not use an ONS 15600 as the GNE and an ONS 15454 as the ENE.

4. The GNE-ENE SNMP community string must be Public.

Overview

A Layer 2 topology can be a point-to-point optical circuit; Resilient Packet Ring (RPR) or an IEEE802.17 RPR consisting of a chain of optical circuits; or hub and spoke, consisting of multiple optical circuits connected in a hub-and-spoke fashion. Hub-and-spoke topologies are supported as multiple point-to-point topologies.

For a point-to-point topology, the following card combinations are supported:

•ML-1000-2/ML-100T-12/ ML-100T-8/ML-100-FX to ML-1000-2/ML-100T-12/ML-100T-8/ML-100-FX card

•ML-1000-2/ML-100T-12/ ML-100T-8/ML-100-FX to CE-100T-8/CE-1000-4/CE-MR-10 card

•ML-1000-2/ ML-100T-12/ML-100T-8/ML-100-FX to OC-N/STM-N/MRC/CTX card

•ML-1000-2/ML-100T-12/ML-100T-8/ML-100-FX to G-series card

•ML-1000-2/ML-100T-12/ML-100T-8/ML-100-FX to E-series card with LEX encapsulation (ONS 15327 NEs only)

When deployed as hub and spoke, the ML-series card can be placed at the spoke locations, with the G-series card providing an extension of the traffic to a Cisco 7600, which forms the hub of the architecture. This arrangement provides a cost-effective way to interface to the Cisco 7600. Alternatively, the ML-series card can be deployed at both the hub and the spoke sites.

When deployed as an RPR or DOT17RPR, all sites contain ML-series cards (ML-1000-2, ML-100T-12, or ML-100T-8). A minimum of two ML-series cards is required to configure an RPR.

You use CTM to provision ML-series cards by opening a Telnet session to each card. Before doing this, provision each ML-series card and create a password configuration that allows you to use CTM to log in. For this purpose, a barebone file is provided on the CTM server disk (Disk 1).

---

Note See the Cisco Transport Manager Release 8.5 User Guide for more information.

---

A different file is provided for the following cards:

•ONS 15310 ML (bareboneCLI_Generic.txt)

•ONS 15454 ML base microcode (barebone15454CLI_Security.txt)

•ONS 15454 ML enhanced microcode (barebone15454CLI_Enhanced_Security.txt)

---

Caution Do not remove any of the information from the barebone file provided by CTM. You can customize the username and password but must not remove them (the username must not be blank). You must not add the enable password <password> command, because CTM cannot interactively enable a password.

---

Reset the ML-series card after loading the barebone file and wait for 5 minutes before provisioning topologies and services. The login and password are reported in the Control Panel window. You can create other profiles on ML-series cards by using the IOS Users table (available under Administration > CTC-Based NEs > IOS Users Table).

After entering command-line interface (CLI) commands through the Telnet session, CTM issues a write or copy run start command to write the Cisco IOS configuration file to the Timing, Communications and Control (TCC) flash. When the Cisco IOS configuration file is written to the TCC flash (by CTM or by another user), CTM is notified. To verify that CTM has been notified, enter the write command after any CLI change.

CTM provides a GUI wizard to facilitate provisioning of L2 topologies and related L1 circuits. Refer to the "Provisioning Data Services" section of Chapter 7, "Provisioning Services and Connections" in the Cisco Transport Manager Release 8.5 User Guide. Create an RPR or point-to-point topology involving some of the ML-series cards in the network. Based on the L2 topology circuit type and size that you specify, CTM creates related L1 circuits and installs a base card configuration on each ML-series card in the RPR ring.

The Create Layer 2 Service wizard guides you through the VLAN creation. There is no CLI to create a circuit VLAN. An RPR supports from 1 to 4095 VLANs, and these VLANs are enabled at all times. All that is required is to configure the endpoint to connect a ring VLAN to an Ethernet port (or port VLAN). Only ML devices are supported on an RPR.

Point-to-point topologies are supported for ML-ML, ML-G1000, ML-OC, and ML-CE cards. Point-to-point topology creation is similar to RPR creation in that based on the L2 topology circuit type and size that you specify, CTM creates related L1 circuits and installs a base card configuration on each ML-series card in the point-to-point topology.

CLI Configuration Details

Note the following CLI conventions:

•Notes are reported within brackets ( [ ] ). For example:

[notes]

•Optional commands or parameters are reported within brackets ( [ ] ). For example:

[match any]

•Configurable parameters are reported within left and right angle brackets (< >). For example:

<parameter>

•Multiple parameters or commands are enclosed within braces ( { } ) and separated by a vertical bar ( | ). For example:

{parameter_1 | parameter_2 | parameter_3}

Base Card Configuration

The base card configuration is a set of commands entered during the L2 topology creation. The parameters are defined in the Create Layer 2 Topology wizard > Layer 2 Topology Bandwidth pane (see Figure 2).

---

Note CTM supports the setting of a single match cos command for each class-map command. If another match cos command is present on the card, CTM recognizes this additional match cos command incorrectly and displays a null string in the GUI. This additional match cos command must be removed during a modify bandwidth operation.

---

Figure 2 Create Layer 2 Topology Wizard

RPR Base Card Configuration

To create an RPR topology, you must apply the base card configuration to all ML-series cards in the RPR. The ring is not functional and is reported as L2 Not Ready until the base card configuration is applied to all cards. You can select an L2 Not Ready RPR in the L2 Topology table and enable the L2 service provisioning by choosing Configuration > Enable L2 Service.

---

Caution If the state is reported as L2 Not Ready, the base card configuration is missing. Choose Configuration > Enable L2 Service to apply the base configuration to the card. This operation affects traffic if the service has already been provisioned on the card.

---

CTM defines the unique card number within the ring. The actual range is from 1 to 251 in any order. Refer to the NE hardware documentation for the number of ML-series cards allowed per RPR.

Note Cisco IOS software supports multiple match cos commands for each class-map command, but CTM supports only one for each.

---

---

Note The multicast/broadcast feature applies only to RPR topologies and requires the ONS 15310 R5.0 or ONS 15454 R5.0 or later.

---

Point-to-Point Base Card Configuration

For a point-to-point topology involved in at least one ML-series card, the other card can be ML, OC, or G1000. The point-to-point base card configuration must be applied only on the ML-series card(s) involved in the topology.

---

Note CTM does not enable spanning tree. Therefore, verify that there are no Layer 2 loops formed by bridged connections outside the ML network. Layer 2 loops in a network without spanning tree enabled might cause network instability.

---

---

Note If a G1000 card is one endpoint in the point-to-point topology, a Network-to-Network Interface (NNI) connection is assumed. That is, the class of service (CoS) coming into the G1000 is trusted (not overwritten).

Ethernet port provisioning involves configuring the following parameters (see Figure 3):

•Enable/Disable Ethernet Ports (Administrative State/Link Control)—The ability to enable or disable an Ethernet port at any time is independent of other port provisioning. CTM automatically disables a port when the last connection is removed.

•MTU Size—Maximum transmission unit (MTU) is the maximum packet size, in bytes, that a particular interface can handle.

•Speed—Select the speed from the drop-down list, which displays three values: 10, 100, and Auto. For an ML1000 card, Auto is the only supported option.

•Flow Control (Send)—Select the Flow Control (send) value from the drop-down list, which displays three values: Off, On, and Desired. These values are supported by both Fast Ethernet and Gigabit Ethernet ports.

PoS port provisioning involves configuring the following parameters (see Figure 3):

•Enable (No Shutdown)/Disable (Shutdown)—The ability to enable or disable a PoS port at any time is independent of other port provisioning. When the PoS port that is shut down is related to the L2 topology, the topology goes into wrap state. CTM automatically sends an alarm indicating that the L2 topology has entered wrap state.

•MTU Size—Maximum packet size, in bytes, that a particular interface can handle.

IEEE 802.17 RPR Base Card Configuration

The base card configuration is a set of commands you enter when creating the Layer 2 topology. Use the Create Layer 2 Topology wizard > Layer 2 Topology Bandwidth pane to define parameters for IEEE 802.17 RPR provisioning (see Figure 4).

Figure 4 Create Layer 2 Topology Wizard—IEEE 802.17 RPR Topology Creation

To create an RPR topology, apply the base card configuration to all ML-series cards in the RPR. The topology is reported as L2 Not Ready until the base card configuration is applied to all cards. Select an L2 Not Ready RPR in the L2 Topology table and choose Configuration > Enable L2 Service to enable the L2 service provisioning.

The IEEE 802.17 policy map configuration differs from the policy map configuration in the Cisco RPR. ML-series cards in 802.17 RPR mode support the following traffic classes:

•Class A (A0/A1)

–Class A0/A1 traffic is guaranteed low-latency traffic.

–Class A0 conforms to the reserved rate on the ring.

–Class A1 does not use the reserved bandwidth.

•Class B (B-CIR/B-EIR)

–Traffic that conforms to the B committed information rate (CIR) is not fairness-eligible.

–Class B EIR traffic is fairness-eligible; it is distinguished from class C traffic at the add node only.

•Class C traffic is best effort; it is always fairness-eligible.

You can modify the CoS value; the range is from 0 to 7.

Use the following commands to create the IEEE 802.17 RPR:

[Class-map configuration]

class-map match-any AVVID_VOICE_VIDEO

match cos <Low Latency Queue Class of Service> 

class-map match-any SP_MANAGEMENT

service-policy output POLICY_QOS_OUT

---

Note The Protection Frame field is always Jumbo; no other configurable options are supported. The Fairness Mode field is always Aggressive.

---

In the commands listed above, the upper limit of the range value depends on the circuit size. For example, if x is the maximum range value in Mbps:

•FOR_STS1 circuit, x = 48

•FOR_STS3c_VC4 circuit, x = 149

•FOR_STS6c_VC4_2c circuit, x = 299

•FOR_STS9c_VC4_3c circuit, x = 488

•FOR_STS12c_VC4_4c circuit, x = 598

•FOR_STS24c_VC4_8c circuit, x = 1196

•FOR_STS9c_VC4_3c circuit, COMMITTED bandwidth, x = 499

•FOR_STS12c_VC4_4c circuit, COMMITTED bandwidth, x= 599

•BW_FOR_STS24c_VC4_8c circuit, COMMITTED bandwidth, x = 1198

Protection Support on ML-Series Cards

You can select IEEE RPR 802.17 ML1000 cards for protection in the Create Layer 2 Topology wizard > Card Selection pane (see Figure 5).

To choose a working card, select any card in the Available Cards list and click Add Working.

To choose a protection card for a working card:

1. Select the working card.

2. Select the protection card from the Available Cards list.

3. Click Add Protect.

---

Note Protection is supported only on ML1000 cards; a working ML1000 card can be protected only by another ML1000 card.

---

Figure 5 Card Selection—Create Layer 2 Topology Wizard (IEEE RPR 802.17)

After you select the protection, commands are issued on the active and protection ML1000 cards, as follows:

•MAC addresses are configured on both the active and protection cards for the IEEE RPR interface:

–Active card protection configuration

interface RPR-IEEE0

mac-address <MAC address of the interface> [Possible MAC address range is 
0000.1111.1111 to 0000.9999.9999]

–Protection card protection configuration

interface RPR-IEEE0

mac-address <MAC address of the interface> [Possible MAC address range is 
0000.1111.1111 to 0000.9999.9999]

•After the MAC address is configured, the following commands are present on the active and protection cards:

–Active card protection configuration

interface RPR-IEEE0

rpr-ieee ri mode primary peer <MAC address of the active card> [Possible MAC 
address range is 0000.1111.1111 to 0000.9999.9999]

–Protection card protection configuration

interface RPR-IEEE0

rpr-ieee ri mode secondary peer <MAC address of the protection card> [Possible MAC 
address range is 0000.1111.1111 to 0000.9999.9999]

---

Note Any MAC address with the first four digits beginning with 11 (11xx.xxxx.xxxx) is a malformed address and is denied; for example, 1100.2222.3333.

---

Wrap Status

When a PoS port participating in a Layer 2 topology is shut down, CTM raises an alarm to indicate that the L2 topology has entered wrap state. The status of the Layer 2 topology changes from the original state (Complete or Incomplete) to Complete-Wrapped or Incomplete-Wrapped (see Figure 6).

Figure 6 Layer 2 Topology Table—Complete-Wrapped State

The Alarm Browser (see Figure 7) displays a wrapped-state alarm.

Figure 7 Alarm Browser—Complete-Wrapped State

---

Note For alarms and circuits on ML cards that are configured with card mode RPR 802.17, the ML card ports are referred to as port 0 for RPR-WEST and port 1 for RPR-EAST. This is also true when CTM communicates through the GateWay/CORBA interface.

---

Creating Service Connections

CTM contains an L2 service provisioning wizard to facilitate provisioning of VLANs over a defined L2 topology. You can define each Ethernet port as user network interface (UNI) or network node interface (NNI). VLANs on an Ethernet port are referred to as port VLANs. VLANs on PoS and SPR ports (and their connected circuits) are referred to as service provider VLANs (or circuit VLANs).

You cannot mix NNI and UNI connections on the same port. CTM supports the following types of service configurations:

•UNI QinQ Access (user VLAN and protocol transparency)—Cannot be combined with other connection types on the same port.

•UNI dot1q Access—Select an unused port VLAN from 1 to 4095. It can be combined with untagged connections on the same port. Each port VLAN can be used for only one connection.

•UNI Untagged Access—Configure as Dot1q Access with port VLAN 1.

•NNI dot1q Access—Select an unused port VLAN from 1 to 4095. It can be combined with untagged connections on the same port. Each port VLAN can be used for only one connection.

The circuit VLAN range is from 1 to 4095. On an RPR, all valid circuit VLANs can be used; however, due to limited bridge group resources, each ML-series card can access only 255 circuit VLANs. Due to limited card-level bridge group resources, only 255 circuit VLANs can be used on a point-to-point circuit.

---

Note VLAN ID 1 is reserved for untagged VLANs.

---

Using the Quality of Service Policy Template

You must configure the following information in the L2 service provisioning and quality of service (QoS) profile wizards:

•Port (FastEthernetM [FEM] or GigabitEthernetN [GIGEN] with M=0 to 11 and N=0,1)

•Service connection type (UNI QinQ, UNI dot1Q, UNI untagged, or NNI dot1Q)

•QoS parameters (selection of the QoS profile name defined in the QoS profile)

CTM assigns an unused bridge group (BG) to the card. The range is from 1 to 255.

The following table lists the configuration information for a best-effort QoS profile. You can select the predefined profile and customize it, or create a new customized profile by using the Advanced option.

Table 3 Configuration Settings for the Best-Effort QoS Profile

The following table lists the configuration information for the committed information rate/peak information rate (CIR/PIR) QoS profile. You can select the predefined profile and customize it, or create a new customized profile by using the Advanced option.

---

Note If you select the CIR/PIR profile and want to modify it, you must configure your own advanced service before you can set the CIR type to Rate_Limited, CIR=PIR, and CIR Burst=PIR Burst.

CTM allows you to define a QoS policy template, starting with the preceding predefined policies and customizing them within the following predefined ranges:

•CIR_PIR

–CIR—96,000 to 800,000,000 bits per second.

–Max CIR Burst—8000 to 64000 bytes.

–PIR—96,000 to 800,000,000 bits per second. Cannot be less than CIR.

–Max PIR Burst—8000 to 64000 bytes. Cannot be less than Max CIR Burst.

–Traffic matching criteria is match-all.

–Only one policy is allowed.

•Best_Effort

–Line Rate—CIR is 96000 bits per second and CIR Burst is 8000 bytes.

–Rate Limited—You configure the CIR and CIR Burst.

–Traffic matching criteria is match-all.

–Only one policy is allowed.

You can create your own advanced QoS policy by entering the customized QoS configuration based on the following parameters:

•Traffic matching criteria.

•CoS—The range is from 0 to 7.

•DSCP—The range is from 0 to 63.

•IP Precedence—The range is from 0 to 7.

•CoS transmit values for CIR/PIR.

•Exceed action and violate action and their CoS transmit values.

•Up to eight QoS classes can be configured.

You must configure the following information in the L2 service provisioning and QoS profile wizards:

•Port (FastEthernetM [FEM] or GigabitEthernetN [GIGEN] with M=0 to 11 and N=0,1).

•Service connection type (UNI QinQ, UNI dot1Q, UNI untagged, or NNI dot1Q).

•QoS parameters (selection of the QoS profile name defined in the QoS profile).

CTM assigns an unused BG to the card. The range is from 1 to 255.

---

Note The CLI commands in this section are written for services defined on the RPR topology. For services defined on point-to-point circuits, replace int spr 1 with int pos 0 or int pos 1, depending on which PoS will carry the service. The bridge x protocol command is never issued. Spanning tree is not enabled for RPR or point-to-point circuits. The L2protocol-tunnel all command is expanded to three separate lines when saved by the Cisco IOS router.

---

For each selected service drop, the configuration is done in three steps:

1. Class map configuration (not required for NNI-configured ports).

2. Policy map configuration (through QoS profiles; not required for NNI-configured ports).

3. Interface configuration (through the Create Layer 2 Service wizard).

The following sections describe the commands for each step.

1. Class Map Configuration

Configuring CIR/PIR Class Map

[Class map configuration for CIRPIR]

Class-map match-all CLASS_BG<BG>_CIRPIR

match bridge-group <BG>

Configuring Best-Effort Class Map

Configuring Advanced Class Map

Figure 8 and Figure 9 show how to use the Create QoS Profile wizard to configure an advanced QoS profile.

Figure 8 Create QoS Profile Wizard—Advanced Class Map Configuration (1 of 2)

Figure 9 Create QoS Profile Wizard—Advanced Class Map Configuration (2 of 2)

Enter the following commands to create a QoS profile with advanced OR selection:

[Class map configuration for ADVANCED OR selection]

be configured on the <Service Drop Port>=0,1 for GigaEthernet and <Service Drop Port>=0 to 
11 for FastEthernet]

[match ip dscp <Match DSCP>]

[if Match DSCP has been selected, the valid range is 0-63]

[match ip precedence <Match IP Precedence>]

[if Match IP Precedence has been selected, the valid range is 0-7]

[match cos <Match CoS>]

[if Match CoS has been selected, the valid range is 0-7]

---

Note A profile with OR conditions can be applied only to a port with a single bridge group configured. CTM excludes the match bridge group statement from the OR class maps and applies class match-any.

---

2. QoS Profile Configuration

[[<Peak Rate> pir <Peak Burst>] is applied only if Excess Traffic is Allowed.] 
[exceed-action drop is applied only if Excess Traffic is Discarded.]

[Trust option is never selectable for Excess Traffic or Violation tab. Mark CoS option 
is always used when the Excess or Violations is Allowed.]

[violation-action drop is applied only if Excess Traffic is Allowed and Violate 
Traffic is Discarded.]

Bandwidth Data Service Provisioning

In the Control Panel > ONS NE Service pane for CTC-based NEs, select the Enable Bandwidth DSP check box to enable the bandwidth data service provisioning check during L2 service provisioning. The bandwidth utilization report shows available and used bandwidth for each L2 topology. Use this report during L2 service provisioning to verify whether the requested CIR is available on the topology. An error is returned if there is not enough bandwidth available for a drop port.

3. Interface Configuration

Adding UNI QinQ Access

Any port with mode dot1q-tunnel is a UNI QinQ access connection. Figure 13 and Figure 14 show how to add UNI QinQ access using the Create Layer 2 Service wizard.

Figure 13 Create Layer 2 Service Wizard—Adding UNI QinQ Access

Figure 14 Create Layer 2 Service Wizard—Configuring Service Drops

Adding UNI dot1Q Access

Figure 15 is an example of the Create Layer 2 Service wizard for adding UNI dot1Q access.

Figure 15 Create Layer 2 Service Wizard—Adding UNI dot1Q Access

The port is recognized as UNI if you enter the service-policy input command on the port interface; otherwise, the port is recognized as NNI. Every subinterface is a dot1q connection. The classification of UNI versus NNI is based on the port-level parsing. A connection is untagged if you enter the encap dot1q 1 command. The multiple class map and QoS policy configurations for advanced QoS are similar to the QinQ Access example shown in Figure 15.

Enter the following commands to create a UNI Dot1q:

IP Service-Level Agreement on ML-Series Cards

IP SLA is an application embedded in Cisco IOS, which enables you to monitor service-level agreements (SLAs) on IP networks. Service levels are measured by downtime, bandwidth, latency, jitter, packet loss, and so on. Using the IP SLA application, you can verify service guarantees, increase network reliability by validating network performance, proactively identify network issues, and increase return on investment (ROI) by easing the deployment of new IP services.

IP SLA can be configured only on ML-series cards participating in point-to-point and RPR L2 topologies.

---

Note IP SLA is not supported on 802.17 RPR.

---

Three steps are required to enable IP SLA features:

1. Create a Managed VLAN.

2. Create an IP SLA Session.

3. Manage the IP SLA Session.

1. Create a Managed VLAN

Create a managed VLAN by selecting IP SLA Managed VLAN in the Layer 2 Service wizard (see Figure 16) to create a managed VLAN. You can create managed VLANs only on already existing point-to-point and RPR L2 topologies.

Figure 16 Layer 2 Service Wizard—Managed VLAN-Enable

In the Service Drops Configuration pane > IP SLA tab (see Figure 17), IP addresses are automatically generated and assigned to all of the service drop points that CTM manages.

Figure 17 Create Layer 2 Service Wizard—IP SLA

For information about commands that are issued based on the provisioning in the Service Drops and Port Attributes tabs, see Creating Service Connections.

The following commands are issued when you assign an IP address to the service drop and specify the routing protocol.

IP Address Assignment

ip address <IP Address> <Subnet> [<IP Address> possible values are 192.168.0.1 to 
192.168.255.255. <Subnet> possible value is 255.255.0.0.] 

Routing Protocol Assignment

bridge <bridgegroupno> route ip [Unique bridgegroupno is created by CTM. Possible values 
are 1 to 255.]

2. Create an IP SLA Session

Create an IP SLA session between a pair of ML-series cards, or between an ML-series card and non-ML IP addresses. Select either Cisco-supported service points or external-destination IP addresses.

You can use the VLAN table (when a managed VLAN is selected) and with the Create IP SLA wizard (see Figure 18) to provision the IP SLA session.

Figure 18 Create IP SLA Wizard

---

Note CTM does not validate nonsupported external destination addresses. Ensure that the external destination is valid and that it responds to a ping command.

---

CTM automatically generates the IP SLA ID. The service drop points are displayed in the source and destination points, and you can pick up any drop point. You can specify a non-CTM supported destination. IP SLA can be enabled during or after creation of the IP SLA session.

---

Note The source and destination port cannot be the same.

---

Two types of probes are supported: jitter and echo. Based on the probe type you select in the Create IP SLA wizard, you must enter additional information.

•If you select the jitter probe, enter a value for the following attributes (see Figure 19):

–Destination Port—1 through 65535

–NoOfPackets—1 through 60000

–Interval—1 through 60000 (in milliseconds)

–TOS (Type of Service)—0 through 255

–Operation Frequency—1 through 604800 (seconds)

Figure 19 Create IP SLA Wizard—Jitter Probe

CTM issues the following commands on the source:

rtr <IPSLA ID> [IPSLA ID number range is from 1 to 2147483647.]

type jitter dest-ipaddr <Destination IP Address> dest-port <Destination Port> 
num-packets <Number of Packets> interval <Interval>

tos <TOS> frequency <Operation Frequency>

The RTR responder is then configured on the destination for jitter operation. For a CTM-supported destination (any ML-series cards), CTM issues the following command on the destination:

rtr (responder)

---

Note For the IP SLA session to work correctly on a destination that CTM does not support, you must enter the rtr (responder) command on the destination.

---

•If you select the echo probe, no additional information is required and CTM issues the following commands on the source:

rtr <IPSLA ID> [IP SLA number range is from 1 to 2147483647.]

type echo protocol ipIcmpEcho <Destination IP Address> source-ipaddr <Source IP 
Address> [Destination IP Address could be a CTM-managed ML card or an external device. 
Source IP Address is always a CTM-managed ML card.]

---

Note Performance monitoring is disabled for the IP SLA echo operation. If you select an echo row in the IP SLA PM table, the Performance menu is disabled.

---

3. Manage the IP SLA Session

To begin collecting, enable the IP SLA session. The operation ends after 3600 seconds, but you can restart it from the Restart IP SLA menu.

Use the IP SLA table (see Figure 20) to enable, restart, and delete IP SLA.

Figure 20 IP SLA Table

Use the following commands to enable, restart, and delete IP SLA:

Enable IP SLA

rtr schedule <IPSLA ID> start-time now [IP SLA Number range is from 1 to 2147483647]

Restart IP SLA

rtr restart <IPSLA ID> [IP SLA Number range is from 1 to 2147483647]

Delete IP SLA

No rtr <IPSLA ID> [IP SLA Number range is from 1 to 2147483647]

---

Note The MIB uses SNMP to retrieve the performance monitoring (PM) statistics on IP SLA.

---

The following table lists the PM data retrieved on IP SLA for jitter. To view the statistics, choose IP SLA Table > Performance (see Figure 20).

Enabling or Disabling Rapid Spanning Tree Protocol

You can enable Rapid Spanning Tree Protocol (RSTP) on UNI dot1Q, UNI Untagged, and NNI dot1Q ports by selecting the RSTP for the selected drop port and then checking the RSTP Enable check box (see Figure 21). To disable RSTP, select the RSTP for the selected drop port and uncheck the RSTP Enable check box.

---

Note RSTP can be enabled only on a drop where UNI/NNI dot1Q is selected and only on a subinterface (that is, UNI dot1Q drop) where no other QinQ drops were created for the same interface.

---

Figure 21 Create Layer 2 Service Wizard—RSTP Enable

Click Next to configure QoS parameters as required (see Figure 22).

Figure 22 Create Layer 2 Service Wizard—QoS Parameters

If the RSTP Enable check box is checked, CTM issues the following command specified for adding a drop:

[Configure RSTP; this command is issued once for VLANs]

bridge <BG> protocol rstp

[Enable RSTP on the selected drop]

Interface {FastEthernet<port>|GigabitEthernet<port>}.<Port VLAN>

Bridge-group <BG>

The following command is issued when you disable RSTP from a drop:

[Disable RSTP on the selected drop]

no cdp enable

ML Management Troubleshooting

If a problem arises during the initial synchronization, you can resynchronize the Layer 2 topology by choosing Configuration > Resync L2 Topology in the Layer 2 Topology table (see Figure 27).

---

Note This feature only restarts the L2 topology resynchronization state. It does not forcefully apply any configuration on the ML-series card to complete the synchronization of the L2 topology.

---

Alternative methods of resynchronization are:

•Mark the NEs participating in the L2 topology as Out of Service, and then In Service.

•Restart the NE service.

Although effective, these methods cause a time lag that affects other functions, such as inventory collection and circuit discovery.

ML Version Up

When you upgrade a node, you can choose to upgrade the software running on the ML-series cards at a later time. The Version Up feature allows you to delay upgrading the ML-series card, and to choose which ML-series card to upgrade to the new version. By using this feature, you can also view the state of the node with respect to the upgrade, which can be:

•Complete upgrade—All the non-ML and ML-series cards have been upgraded to the new software release.

•Partial upgrade—The ML-series cards have not all been upgraded to the new software release.

To enable the Version Up feature, complete the following steps:

1. Set the value for the parameter NODE.Software.AllowDelayedUpgrade in the Value column under the NE Defaults tab to TRUE (see Figure 28).

Figure 28 NE Explorer—NE Defaults Tab

2. Activate the NE software. Use the Bulk Software Activation wizard to activate the NE software (see Figure 29). For specific instructions, see the section "Scheduling Bulk Software Activation" in Chapter 4, "Maintaining an Efficient Network" in the Cisco Transport Manager Release 8.5 User Guide.

Figure 29 Bulk Software Activation Wizard

During NE software activation, you are asked if you want to delay the software upgrade on the ML-series cards (see Figure 30). For specific instructions, see the section "Delaying Software Activation on the ML-Series Cards" in Chapter 4, "Maintaining an Efficient Network" in the Cisco Transport Manager Release 8.5 User Guide.

Figure 30 Software Activation

---

Note•While ML-series cards on the NE are waiting to be upgraded, all provisioning operations and software downloads on the NE are disallowed.

•You can upgrade the NE fully to the latest version by resetting all the ML-series cards to this version.

---

After a successful partial software activation on the NE, the NE Software table (see Figure 31) displays True in the Partial Upgrade column, which indicates that the activation is pending for ML-series cards.

3. Upgrade the ML-series cards to the current version by resetting them on the NE in either of the following ways:

–Select multiple ML-series cards and choose Edit > Reset ML Cards in the NE Software table. For specific instructions, see the section "Activating a New NE Software Version on One or More ML-Series Card(s)" in Chapter 4, "Maintaining an Efficient Network" in the Cisco Transport Manager Release 8.5 User Guide.

–For individual ML-series cards, use the NE Explorer.

The Partial Upgrade column in the NE Software table displays FALSE when all ML-series cards are upgraded to the current version.

Figure 31 NE Software Table—Reset ML Cards

Enable L2 Service Command Enhancement

The enable L2 service command has been enhanced. (See the "Enabling a Layer 2 Service" section of Chapter 7 in the Cisco Transport Manager Release 8.5 User Guide.)

The enable L2 service command is used only when the resynchronization status of the topology is L2 Service Not Ready, and its main purpose is to change the Layer 2 topology into a resynchronization status of Complete so that a VLAN can be created.

Instead of commanding the default base card configuration on all ML-series cards in the topology to be downloaded, this command downloads a customized base card configuration on only the selected Layer 2 topology ML-series cards that do not have the customized configuration and are in a synchronized configuration state (barebone file downloaded).

This command applies to point-to-point, Cisco RPR, and 802.17 RPR Layer 2 topologies.
