Enterasys Networks VH-2402S manual RFC 1213 MIB-II, RFC 1573 Interfaces Evolution MIB

RFC 1213 (MIB-II)

RFC 1213 provides management of system-level parameters, including TCP/IP protocol-related statistics, IP addressing, and interface statistics for each switch port. MIB-II is the standard MIB defined by RFC 1213. All agent devices operating SNMP are required to support at least part of MIB-II.

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 VH-2402S 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 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 1573 (Interfaces Evolution MIB)

RFC 1573 clarifies and extends the managed objects of the “Interfaces” group of MIB-II. This MIB takes account of the evolution in interface types and speeds employed in today’s networks.

RFC 1643 (Ethernet-Like MIB)

RFC 1643 provides management and monitoring for the Ethernet-specific aspects of each port on the switch. This is the Ethernet-specific statistics 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.
