9032785 SNMP Management 69

This MIB reports information about the protocols and network interfaces

supported on the agent itself, as well as other general inf ormation. The

MIB is divided into a number of groups, each of which co rresponds to a

specific protocol or set of information. Some groups are defined in other

RFC documents.

The groups specifically defined in RFC 1213 and supported by the

ELS100-24TXM switch system software are as follows:

•System – General information about the agent system

•Interfaces – Information about the network interfaces of the system

•Address Translation – Interface address information, both MAC level

and network (IP) level

•IP – Statistics and information related to the IP protocol

•ICMP – Statistics and information related to the ICMP protocol

•TCP – Statistics and information related to the TCP pro tocol

•UDP – Statistics and information related to the UDP protocol

•Transmission – Statistics and information related to the physical

network medium to which the system interfaces (e.g. Ethernet, token

ring, etc.).

•SNMP – Statistics and information related to the SNMP pr otocol

RFC 1398 (Ethernet MIB)

RFC 1398 provides management and monitoring for the Ethernet- specific

aspects of each port on the switch. This is the Ethernet-specific statistics

subgroup of the MIB-II Transmission group. This group provides a set of

statistics related to Ethernet’s physical level operation. Specifically, error

and collision-related statistics are presented.

RFC 1493 (Bridge MIB)

RFC 1493 is a group defined under MIB-II. This MIB deals with the

operation of the system as an 802.1D-compliant bridge. Areas of

functionality supported by this group include Spanning Tree and

forwarding table information and configuration.

RFC 1757 (RMON MIB)

RFC 1757 is a group defined under MIB-II. This MIB provides

management for the RMON aspects of the switch. The ELS100-24TXM

switch supports four of the nine groups of RMON defined for Ethernet

networks on a per port basis. For further information, see the subsection

“RMON” in Chapter 1.
