What is h3cVsanDmNewPrincipalSwitchNotify?

This notification is sent when a switch is elected as the new Principal Switch in a Virtual SAN (Storage Area Network), indicating a change in the VSAN's leadership. Network operators track this event to monitor VSAN stability and understand topology changes. It includes the new Principal Switch's World Wide Name and the affected VSAN index.

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> '' H3C-VSAN-MIB::h3cVsanDmNewPrincipalSwitchNotify
snmptrap -v2c -c public <manager> '' 1.3.6.1.4.1.2011.10.2.127.1.1.3.0.2

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
