Which port is used for SNMP polling?

Explanation:
SNMP polling relies on asking the device for information, and the device’s agent listens for those requests on UDP port 161. When the manager sends a GET/GETNEXT/GETBULK request to port 161, the agent processes it and replies back to the manager on the same conversation. The trap mechanism is separate: agents push asynchronous alerts to the manager on port 162, not used for regular polling. Ports like 514 (syslog) and 80 (HTTP) are unrelated to SNMP polling. So the port used for SNMP polling is 161.
