Enterasys Networks 5G1XX, 5H1XX manual RFC 1493 Bridge MIB, RFC 1573 Interfaces Evolution MIB

MIB Objects

The groups specifically defined in RFC 1213 and supported by the 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

11.2.2 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.

11.2.3 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.

11.2.4 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.

11.2.5 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 switch supports four of the nine groups of RMON defined for Ethernet networks on a per port basis.
