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> '' MELLANOX-XSTP-MIB::mellanoxXstpRootBridgeChange snmptrap -v2c -c public <manager> '' 1.3.6.1.4.1.33049.13.1.1.1
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]:52838->[192.168.30.10]:162]: DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (344717414) 39 days, 21:32:54.14 SNMPv2-MIB::snmpTrapOID.0 = OID: MELLANOX-XSTP-MIB::mellanoxXstpRootBridgeChange
