Module: CISCO-WAN-ATM-CONN-STAT-MIB

OID (symbolic): CISCO-WAN-ATM-CONN-STAT-MIB::cwacsEgrAal2CpsInvalidCidPkts

OID (numeric): 1.3.6.1.4.1.351.150.2.1.1.4.1.6

Node type: OBJECT-TYPE

Type: Counter32

Access: read-only

Description: The number of AAL2 CPS packets dropped in the egress direction due to invalid CID. The CID may be considered as invalid if - a) It is out of range. b) It is not configured

CID is Channel ID of a voice channel which set-up within PVC/SVC(only AAL2) and the CID is unique within the context of PVC/SVC.

What is cwacsEgrAal2CpsInvalidCidPkts?

This Counter32 counts AAL2 CPS packets dropped in the egress direction because their CID (Channel ID) was invalid -- either out of range or not configured -- where the CID identifies a specific voice channel multiplexed within this PVC/SVC. Growth here typically means a voice channel is being referenced that hasn't been provisioned on this connection, or a configuration mismatch between endpoints. An admin seeing a specific voice call fail to connect over an AAL2 trunk would check this counter and then verify the CID is properly configured on both ends.
