What is port 162?

SNMP Trap on UDP port 162 is used by network devices (routers, switches, UPS units) to send unsolicited alert notifications to a monitoring server when significant events occur — such as a link going down, high CPU utilization, or an authentication failure. This is the reverse of port 161: instead of the manager polling the device, the device proactively notifies the manager.
