Enterasys Networks VH-8G manual MIB Objects, RFC 1213 MIB-II

Page 88

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-8G 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-8G 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-8G switch also supports Enterasys proprietary MIB extensions.

RFC 1213 (MIB-II)

RFC 1213 provides management of system-level parameters, including TCP/IP protocol-related statistics, IP addressing, and interface statistics for each switch port. MIB-II is the standard MIB defined by RFC 1213. All agent devices operating SNMP are required to support at least part of MIB-II.
