What ports does SNMP use?

There are three main network ports (and one named socket), which are typically used by SNMP. These are:

    UDP port 161       - SNMP requests (GET* and SET)
    UDP port 162       - SNMP notifications  (Traps/Informs)
    TCP port 705       - AgentX
    /var/agentx/master - AgentX

However, these are simply the default "well-known" ports for these purposes, and it is perfectly possible to accept requests on other ports.
