If the configuration is changed to move from SNMP v2c to SNMP v3, the system generates new Engine ID which is used for both SNMP queries and traps. The same port number may be unofficialy used by various services or applications. There are two modes of operation with SNMP - get requests (or polling) where one device requests information from an SNMP enabled device on a regular basis (normally using UDP port 161), and traps where the SNMP enabled device sends a message to another device when an event occurs (normally using UDP port 162). UDP 161 – Disclaimer. Alarm-reporting options for the system. SNMP is a network protocol that allows managing many network devices from one location. SNMP manager sends this message to request data from SNMP agent. It will work anyway even if you block this port in iptables, assuming that you're allowing responses to established traffic as usual - your outbound mobilization requests to your chosen servers will be enough to allow the responses, and the same with further traffic sent for the lifetime of ntpd. When you set up a Windows computer to print to a network print device via a standard IP printer port, Windows turns on a setting on the IP printer port in its print server settings that queries the printer via SNMP to determine whether it is online or offline.
