ThisMIB reports information about the protocols and network interfaces
supportedon the agent itself, as well as other general information. The
MIBis divided into a number of groups, each of which corresponds to a
specificprotocol or set of information. Some groups are defined in other
RFCdocuments.
Thegroups specifically defined in RFC 1213 and supported by the
ELH100-12/24TXhub system software are as follows:
•System– General information about the agent system
•Interfaces– Information about the network interfaces of the system
•AddressTranslation – Interface address information,both MAC level
andnetwork (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 – Statistics and information rela ted to the physical
networkmedium to which the system interfaces (e.g. Ethernet,token
ring,etc.).
•SNMP– Statistics and information related to the SNMP protocol
RFC2108 (Multi-segment Repeater)
RFC2108 provides management and monitoring for multi-segment
repeaters.This group provides a set of managed objects for devices
(repeaters,MAUs, interfaces) that conformto the IEEE 802.3 standard for
Ethernet.
RFC 1643(Ethernet-like)
RFC1643 provides management and monitoring for the Ethernet-specific
aspectsof each segment on the hub. Instances of these object types
representattributes of an interface to an Ethernet-like communications
medium.
RFC 1757 (RMON MIB)
RFC1757 is a group defined under MIB-II. This MIB provides
managementfor the RMON aspects of the hub. The ELH100-12/24TX
hubsupports four of the nine groups of RMON defined for Ethernet
networkson a per segment basis. For further information, see the
subsection“RMON” in Chapter 1 or “RMON Browser” in Chapter 5.
Cabletron Proprietary MIB Extensions
Areasof ELH100-12/24TX hub functionality not covered by the standard
RFCMIBs are specified in the Cabletron private MIB. This MIB definition
isspecified separately from MIB-II. Areas covered in this MIB include
varioussystem, hub, and port level information.
