82 SNMP Management VH-2402S

There are three main operations defined in SNMP:

•GET operations read information from the managed device, such as

those used to obtain status or statistical data.

•SET operations change a functional parameter on the device, such

as those used to configure Port Speed or to initiate a software

download. GET and SET operations are initiated only by the

manager software, and result in a response by the agent.

•TRAP operations allow the agent to send an unsolicited message to

the manager. This operation is typically used as an alert of a potential

problem or a change of status with the device. The Trap Destination

parameter in the SNMP Configuration Menu is used to configure the

IP addresses of the SNMP Manager to which VH-2402S trap

messages are sent.

MIB Objects

A number of standard MIB specifications have been defined for managing

network equipment. SNMP compliant devices typically support one or

more standard MIBs defined by the Internet Engineering Task Force

(IETF), in the form of Request for Comments (RFC) documents.

These MIBs provide a common method of managing devices, such as

hubs and switches, and network interfaces, such as Ethernet and token

ring. The primary standard MIB, referred to as MIB-II, provides an overall

view of the managed agent and must be supported, at least in part, by all

SNMP agents. In addition, proprietary MIB extensions are defined by

commercial vendors for managing device-specific functions of their

products.

The VH-2402S switch supports six standard MIBs:

•RFC 1213 - Management Information Base for Network

Management of TCP/IP based Internets (MIB-II)

•RFC 1573 - Evolution of the Interfaces Group of MIB-II

•RFC 1643 - Definitions of Managed Objects for the Ethernet-like

Interface Types (Ethernet-Like MIB)

•RFC 1493 - Definitions of Managed Objects for Bridges

•RFC 1757 - Remote Network Monitoring Management Information

Base

•IEEE 802.1Q - VLAN Bridge Management (Q-MIB)

The VH-2402S switch also supports Enterasys proprietary MIB

extensions.
