3.7.9 SNMP
SNMP (Simple Network Management Protocol) is a troubleshooting and management protocol,
which uses the UDP protocol on port 161 to communicate between clients and servers. SNMP
uses a manager MIB (management information base) agent solution to fulfill the network
management needs. The agent is a separate station that can request data from an SNMP agent in
each of the different managed system in the network. The agent uses the MIBs as dictionaries of
manageable objects. Each SNMP-managed device has at least one agent that can respond to the
queries from the NMS. The SNMP agent supports GETS, SETS, and TRAPS for 4 groups with
MIB-II: System, Interface, IP, and ICMP. The SNMP agent supports three-community names
authentication. See
