Description: This notification indicates that a particular switch, identified by t11FamLocalSwitchWwn, has become the new Principal Switch on the Fabric identified by t11FamNotifyFabricIndex.

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> '' T11-FC-FABRIC-ADDR-MGR-MIB::t11FamNewPrincipalSwitchNotify
snmptrap -v2c -c public <manager> '' 1.3.6.1.2.1.137.0.2

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

Example snmptrapd log entry:
