Module: CISCO-VISM-CONN-STAT-MIB
OID (symbolic): CISCO-VISM-CONN-STAT-MIB::vismChanAal2InvParCells
OID (numeric): 1.3.6.1.4.1.351.110.5.5.3.3.1.1.15
Node type: OBJECT-TYPE
Type: Counter32
Access: read-only
Description: This object keeps track of the number of AAL2 cells dropped due to invalid Parity bit field in the egress direction.
What is vismChanAal2InvParCells?
This Counter32 tracks the number of AAL2 cells dropped due to an invalid Parity bit field in the egress direction. A failing parity check on egress AAL2 cells indicates bit-level corruption is affecting cells as they're transmitted, which can be an early sign of a hardware or transmission-line problem. An engineer troubleshooting a channel with occasional audio glitches would check this counter alongside the HEC and CRC error counters to build a fuller picture of where cell-level corruption is occurring.
