cbsDbhaLinkDown
Module: CBS-HARDWARE-MIB
OID (symbolic): CBS-HARDWARE-MIB::cbsDbhaLinkDown
OID (numeric): 1.3.6.1.4.1.6848.4.1.20
Node type: NOTIFICATION-TYPE
Description:
The DBHA link on this CPM has failed.
What is cbsDbhaLinkDown?
This SNMP notification (trap) is generated when the Distributed Billing and High-Availability (DBHA) redundancy link between CPM modules fails. The DBHA link carries replication traffic to keep redundant CPM cards synchronized; failure triggers an alarm to alert operators to a critical redundancy issue. Network administrators monitor for this trap to initiate failover procedures or manual recovery.
Examples
Send this trap to an SNMP manager — replace <manager> with the IP or hostname of your monitoring server (SNMPv2c):
snmptrap -v2c -c public <manager> '' CBS-HARDWARE-MIB::cbsDbhaLinkDown snmptrap -v2c -c public <manager> '' 1.3.6.1.4.1.6848.4.1.20
Listen for incoming traps on the manager host (-f keeps it in the foreground, -Lo prints to stdout — useful for testing):
snmptrapd -f -Lo -c /dev/null authCommunity log public
