cwtNodeId
Module: CISCO-WAN-TOPOLOGY-MIB
OID (symbolic): CISCO-WAN-TOPOLOGY-MIB::cwtNodeId
OID (numeric): 1.3.6.1.4.1.9.9.234.1.2.1.1.3
Node type: OBJECT-TYPE
Type: PnniNodeId
Access: read-write
Description: The unique Id which identifies the node in the entry. This value is different from cwtIndex because it is a unique number which identifies a node in the ATM network, while cwtIndex is an index for an entry in the topology database. The same physical node can have different cwtIndex in different topology databases.
What is cwtNodeId?
This read-write object, typed as PnniNodeId, holds the unique identifier for a node in the ATM network, which is different from the table's own cwtIndex because the same physical node can have different cwtIndex values across different topology databases. An admin relies on cwtNodeId rather than cwtIndex when trying to correlate the same physical switch as it appears in multiple topology database views. For example, if a switch shows up with cwtIndex 5 on one gateway and cwtIndex 12 on another, matching cwtNodeId across both confirms it's the same physical node.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.9.9.234.1.2.1.1.3 snmpwalk -v2c -c public <target> CISCO-WAN-TOPOLOGY-MIB::cwtNodeId
Get a specific instance (index 1):
