Explanation:
Detailed explanation-1: -161 or 162? SNMP uses both port 161 and port 162 for sending commands and messages. The “SNMP manager” at the head of your system sends commands down to a network device, or “SNMP agent, ‘’ using destination port 161.
Detailed explanation-2: -SNMP ports are utilized via UDP 161 for SNMP Managers communicating with SNMP Agents (i.e. polling) and UDP 162 when agents send unsolicited Traps to the SNMP Manager.
Detailed explanation-3: -Get-NMS retrieves the value of an object node in an agent MIB. Set-NMS modifies the value of an object node in an agent MIB. Notification-SNMP notifications include traps and informs. The SNMP agent sends traps or informs to report events to the NMS.
