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.

Five 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).

• FCEOS MIB, the McDATA enterprise specific MIB supporting the

McDATA switch and director firmware.
