9032947 SNMP Management 67
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
ELS100-24TXG 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 ELS100-24TXG
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.
