9033060 SNMP Management 89This MIB reports information about the protocols and network interfacessupported on the agent itself, as well as other general information. TheMIB is divided into a number of groups, each of which corresponds to aspecific protocol or set of information. Some groups are defined in otherRFC documents.The groups specifically defined in RFC 1213 and supported by theELH100-12/24TX hub 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 leveland 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 – Statistics and information related to the physicalnetwork medium to which the system interfaces (e.g. Ethernet, tokenring, etc.).• SNMP – Statistics and information related to the SNMP protocolRFC 2108 (Multi-segment Repeater)RFC 2108 provides management and monitoring for multi-segmentrepeaters. This group provides a set of managed objects for devices(repeaters, MAUs, interfaces) that conform to the IEEE 802.3 standard forEthernet.RFC 1643 (Ethernet-like)RFC 1643 provides management and monitoring for the Ethernet-specificaspects of each segment on the hub. Instances of these object typesrepresent attributes of an interface to an Ethernet-like communicationsmedium.RFC 1757 (RMON MIB)RFC 1757 is a group defined under MIB-II. This MIB providesmanagement for the RMON aspects of the hub. The ELH100-12/24TXhub supports four of the nine groups of RMON defined for Ethernetnetworks on a per segment basis. For further information, see thesubsection “RMON” in Chapter 1 or “RMON Browser” in Chapter 5.Cabletron Proprietary MIB ExtensionsAreas of ELH100-12/24TX hub functionality not covered by the standardRFC MIBs are specified in the Cabletron private MIB. This MIB definitionis specified separately from MIB-II. Areas covered in this MIB includevarious system, hub, and port level information.
