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

OID (symbolic): CISCO-WAN-ATM-CONN-STAT-MIB::cwacsEgrAal2HecErrors

OID (numeric): 1.3.6.1.4.1.351.150.2.1.1.4.1.1

Node type: OBJECT-TYPE

Type: Counter32

Access: read-only

Description: The number of egress AAL2 CPS(Common Part Sub-layer) PDUs dropped due to HEC (Header Error Control) error.

What is cwacsEgrAal2HecErrors?

This Counter32 counts, in PDUs, the number of egress AAL2 Common Part Sub-layer (CPS) packets dropped due to a Header Error Control (HEC) error. HEC errors indicate the CPS packet header failed its error-check, meaning the packet's header was corrupted before it could be processed for transmission. An admin troubleshooting dropped voice calls on an AAL2 trunking connection would check this counter to see if header corruption, rather than congestion, is causing the packet loss.
