22 SNMP Reference for Directors and Edge Switches
SNMP Management
SNMP is a transmission control protocol/internet protocol (TCP/IP) that uses the
user datagram protocol (UDP) or other protocols such as UDP/IP to exchange
messages between an SNMP agent (in a managed device) and a management
station residing on a network. Because SNMP does not rely on the underlying
communication protocols, it can be made available over other protocols.
Overview
To be monitored and managed remotely by a network management station, each
Edge 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
RFC 1213.
■ Fabric Element MIB containing support for FL_Ports as specified in Fibre
Channel standards.
■ Fibre Alliance MIB (also referred to as the FCMGMT MIB).
■ FCEOS MIB, which is the HP enterprise-specific MIB supporting HP Edge
Switch and Director firmware.
■ SNMP Framework MIB
