Which port is SNMPTRAP?

Explanation:
SNMP traps are unsolicited notifications sent by managed devices to an SNMP manager to report events, and they are received on port 162 by default. This is the port designated for SNMPTRAP, typically used over UDP (and sometimes TCP in some implementations). In contrast, standard SNMP queries use port 161, not traps. The other ports correspond to different services: 137 is NetBIOS name service, 179 is BGP, and 500 is ISAKMP for IKE in VPNs. So the SNMPTRAP port is 162.
