Description: An mplsLspChange trap signifies that the the specified LSP has switched traffic to the new active path 'toLspPath'. The LSP maintains up state before and after the switch over

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> '' FOUNDRY-MPLS-MIB::snMplsLspChange
snmptrap -v2c -c public <manager> '' 1.3.6.1.4.1.1991.0.1012

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]:61591->[192.168.30.10]:162]:
