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> '' AT-GS950-24-MIB::dot1wTopologyChgTrap snmptrap -v2c -c public <manager> '' 1.3.6.1.4.1.207.1.4.167.119.3.0.4
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:
