What is vismChanAal2CpsInvCidPkts?

This Counter32 tracks AAL2 CPS packets dropped in the egress direction due to an invalid CID, where invalid means the CID is out of range or not configured. A rising count here on a specific channel usually points to a mismatch between the CIDs being sent by the far end and what's actually configured locally on this channel. An engineer troubleshooting a multiplexed AAL2 PVC where some voice channels aren't coming through would check this counter to see if invalid CID values are causing packets for that channel to be dropped.
