9033060 SNMP Management 89
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
ELH100-12/24TX 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 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 – 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 protocol
RFC 2108 (Multi-segment Repeater)
RFC 2108 provides management and monitoring for multi-segment
repeaters. This group provides a set of managed objects for devices
(repeaters, MAUs, interfaces) that conform to the IEEE 802.3 standard for
Ethernet.
RFC 1643 (Ethernet-like)
RFC 1643 provides management and monitoring for the Ethernet-specific
aspects of each segment on the hub. Instances of these object types
represent attributes of an interface to an Ethernet-like communications
medium.
RFC 1757 (RMON MIB)
RFC 1757 is a group defined under MIB-II. This MIB provides
management for the RMON aspects of the hub. The ELH100-12/24TX
hub supports four of the nine groups of RMON defined for Ethernet
networks on a per segment basis. For further information, see the
subsection “RMON” in Chapter 1 or “RMON Browser” in Chapter 5.
Cabletron Proprietary MIB Extensions
Areas of ELH100-12/24TX hub functionality not covered by the standard
RFC MIBs are specified in the Cabletron private MIB. This MIB definition
is specified separately from MIB-II. Areas covered in this MIB include
various system, hub, and port level information.
