9032579-03 SNMP Management 65

This MIB reports information about the protocols and network interfaces

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

MIB is divided into a number of groups, each of which corresponds 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

ELS100-24TX 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 addr ess inform ation, both M AC 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 protocol

•UDP – Statistics and information related to the UDP protocol

•Transmission – Stat istics and informa tion related to the phy sical

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

ring, etc.).

•SNMP – Statistics and information related to the SNMP protocol

RFC 1398 (Ethernet MIB)

RFC 1398 provides management and monito ring for the Ethe rnet-spec ific

aspects of each po rt on the switch. This is the Ethe rnet-specific st atistics

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 ELS100-24TX

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.
