unresolvedMAC

Module: MSCR-MIB

OID (symbolic): MSCR-MIB::unresolvedMAC

OID (numeric): 1.3.6.1.4.1.629.1.50.1.0.1

Node type: NOTIFICATION-TYPE

Description: The SNMP trap that is generated when the Port receives frame with source address not included in this port's MAC security table.

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> '' MSCR-MIB::unresolvedMAC
snmptrap -v2c -c public <manager> '' 1.3.6.1.4.1.629.1.50.1.0.1

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]:57844->[192.168.30.10]:162]:
  DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (284670452) 32 days, 22:45:04.52
  SNMPv2-MIB::snmpTrapOID.0 = OID: MSCR-MIB::unresolvedMAC
