Module: CISCO-WAN-ATM-CONN-STAT-MIB
OID (symbolic): CISCO-WAN-ATM-CONN-STAT-MIB::cwacsEgrAal2InvalidParCells
OID (numeric): 1.3.6.1.4.1.351.150.2.1.1.4.1.3
Node type: OBJECT-TYPE
Type: Counter32
Access: read-only
Description: The Number of AAL2 cells dropped due to invalid Parity bit field in the egress direction.
What is cwacsEgrAal2InvalidParCells?
This Counter32 counts the number of AAL2 cells dropped in the egress direction due to an invalid Parity bit field, used to detect bit errors in the cell. Growth here indicates cells are failing this parity check before egress transmission, pointing to signal or processing errors on the AAL2 path. An admin diagnosing a noisy AAL2 trunk would monitor this counter alongside the OSF and HEC error counters to isolate which validation stage is catching the corruption.
