Explanation

SNMP (Simple Network Management Protocol) uses UDP port 161 by default for receiving queries from network management systems (NMS), and UDP port 162 for sending SNMP traps (unsolicited alerts) to the NMS. Port 53 is DNS. Port 67 is DHCP (server-side). Port 61 is not a standard well-known port. Knowing SNMP's default ports is fundamental for firewall configuration and network monitoring setups - port 161 for polling managed devices and port 162 for receiving trap notifications.
