2 McDATA SNMP Support Overview SNMP is a protocol that uses the User Data Protocol (UDP) to exchange messages between an SNMP agent (in a managed device) and a management station residing on a network. Although SNMP can be made available over other protocols, McDATA only supports UDP. To be monitored and managed remotely by a network management station, each switch or director is equipped with an SNMP agent. This agent is a software process within the switch that receives management requests and generates corresponding responses by accessing the data specified for the MIB-II, Fabric Element MIB, Fibre Alliance MIB, and FCEOS enterprise specific MIB. In addition, the agent gives each switch the ability to notify a management station when an important event occurs by sending a trap to the management station. Seven MIBs are supported: • A subset of the Standard MIB-II for TCP/IP -based Internet as specified in RFC1213. • Fabric Element MIB containing support for FL ports as specified in Fibre Channel standards. • Fibre Alliance MIB (also referred to as the FC Management MIB). • Fibre Alliance MIB, version 3.0 McDATA SNMP Support 2-1
