cpwVcIdMappingVcIndex
Module: CISCO-IETF-PW-MIB
OID (symbolic): CISCO-IETF-PW-MIB::cpwVcIdMappingVcIndex
OID (numeric): 1.3.6.1.4.1.9.10.106.1.7.1.5
Node type: OBJECT-TYPE
Type: CpwVcIndexType
Access: read-only
Description: The value that represent the VC in the cpwVcTable.
What is cpwVcIdMappingVcIndex?
This object exists purely to cross-reference an alternate lookup table (indexed by VC ID) back to the actual row for this pseudowire in the primary cpwVcTable, returning that primary table's index value. Many pseudowire signaling and label protocols reference VCs by a numeric VC ID rather than the SNMP table index, so this mapping is what lets a management station translate 'VC ID from the wire protocol' into 'the specific row I need to poll for status and counters.' Without this mapping object, correlating an alarm reported by VC ID 4500 back to the correct cpwVcTable entry would require guesswork.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.9.10.106.1.7.1.5 snmpwalk -v2c -c public <target> CISCO-IETF-PW-MIB::cpwVcIdMappingVcIndex
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.9.10.106.1.7.1.5.1 snmpget -v2c -c public <target> CISCO-IETF-PW-MIB::cpwVcIdMappingVcIndex.1
