22 SNMP Reference for Directors and Edge Switches
SNMP Management
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, HP StorageWorks Directors, Edge Switches, and the HA-Fabric
Manager (HAFM) application only support UDP.
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, or 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.
Six 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 FC Management MIB), v3.0.
■ Fibre Alliance MIB (also referred to as the FC Management MIB), v3.1.
■ FCEOS MIB, which is the HP enterprise-specific MIB supporting HP Edge
Switch and Director firmware.
■ SNMP Framework MIB.
EOS Trap Overview
All EOS traps are SNMPv1 format, regardless of MIB definition syntax.)
SNMP traps are specific types of SNMP messages enclosed in user datagram
protocol (UDP) packets as shown:
[ IP Packet [ UDP Packet [ SNMP Message ] ] ]
The SNMP message format is:
