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> '' NORTEL-NETWORKS-MULTIPLE-SPANNING-TREE-MIB::nnMstErrorEvent
snmptrap -v2c -c public <manager> '' 1.3.6.1.4.1.45.5.5.0.2

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]:60267->[192.168.30.10]:162]:
  DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (422567275) 48 days, 21:47:52.75
  SNMPv2-MIB::snmpTrapOID.0 = OID: NORTEL-NETWORKS-MULTIPLE-SPANNING-TREE-MIB::nnMstErrorEvent
