Cisco Cisco Transport Manager 9.1 Technical References

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, including provisioning of interface ports for ML data cards. The syntax 
used for the commands must be respected for services provisioned directly using Cisco IOS so that CTM 
recognizes the provisioned services.

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 

 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 

).
