What is apSysMgmtSingleUnitRedundancyTrap?
This notification fires when a chassis slot's operational status changes, such as when a redundant module transitions to active or a standby module fails. The trap includes the slot ID, module type, and the new redundancy state so operators can quickly identify which component changed. System administrators use this event to monitor hardware redundancy status, detect failover events, and maintain awareness of chassis module health.
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> '' APSYSMGMT-MIB::apSysMgmtSingleUnitRedundancyTrap snmptrap -v2c -c public <manager> '' 1.3.6.1.4.1.9148.3.2.3.0.3
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
