Description: The last-received CCM that triggered a DefXconCCM fault.

What is dot1agCfmMepXconCcmLastFailure?

Holds the raw content of the last received CCM that triggered a cross-connect (Xcon) fault on this MEP. Use this to identify exactly which unexpected CCM caused the cross-connection alarm, useful evidence when tracking down a misconfigured MA elsewhere in the network.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.0.8802.1.1.3.1.6.1.1.22
snmpwalk -v2c -c public <target> IEEE802171-CFM-MIB::dot1agCfmMepXconCcmLastFailure

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.0.8802.1.1.3.1.6.1.1.22.1
snmpget -v2c -c public <target> IEEE802171-CFM-MIB::dot1agCfmMepXconCcmLastFailure.1
