Module: CISCO-DM-MIB

OID (symbolic): CISCO-DM-MIB::dmNewPrincipalSwitchNotify

OID (numeric): 1.3.6.1.4.1.9.9.302.1.3.0.2

Node type: NOTIFICATION-TYPE

Description: This notification indicates that the sending switch has become the new Principal Switch on a VSAN. This notification is sent soon after its election as the new Principal Switch, i.e., upon expiration of a Principal Switch selection timer which is equal to twice Fabric Stability Timeout value (F_S_TOV).

This notification contains the vsanIndex of the VSAN on which the switch became the Principal Switch and the WWN of the switch which became the Principal Switch.

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> '' CISCO-DM-MIB::dmNewPrincipalSwitchNotify
snmptrap -v2c -c public <manager> '' 1.3.6.1.4.1.9.9.302.1.3.0.2

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:

zoo11-linux.zoo [UDP: [192.168.30.111]:60333->[192.168.30.10]:162]:
