Managing with SNMP
The resident SNMP agent allows remote Switch management via IP over
Ethernet and Fibre Channel interfaces and provides access to most of the
functions described in the front panel Menu section.
This section provides an overview of key concepts about Switch management
based on Simple Network Management Protocol (SNMP). Additionally, refer
to other references and text books on SNMP for more detailed discussions of
the protocol and usage.
Within the SNMP model, a manageable network consists of one or more
manager systems (or network management stations), and a collection of agent
systems (or network elements):
■
A manager system runs a management application (such as
StorageWorks Command Console GUI) that monitors and controls the
network elements
■
An agent system is a network device such as a Fibre Channel Switch, a
managed hub, or a bridge, that has an agent responsible for carrying out
operations requested by the manager. Therefore, an agent is the interface
to a managed device.
The manager communicates with an agent using the Simple Network
Management Protocol (SNMP). The Switch agent supports both SNMP
version 1 (SNMPv1) and Community-based SNMP version 2 (SNMPv2C).
A manager can retrieve management information, such as its identification,
from an agent. There are three operations for this activity:
■ SNMP-GET
■ SNMP-NEXT
