MIB-II defines a set of manageable objects in various layers of the TCP/IP protocol suites. MIB-II covers all manageable objects from Layer 1 to Layer 4, and, as a result, is the major SNMP MIB supported by all vendors in the networking industry. The Hardened Ethernet Extender Switch supports a complete implementation of SNMP Agent and MIB-II.

5.1.3 RMON MIB (RFC 2819) and Bridge MIB (RFC 1493)

The Hardened Ethernet Extender Switch provides hardware-based RMON counters in the Hardened Ethernet Extender Switch chipset. The Hardened Ethernet Extender Switch manager CPU polls these counters periodically to collect the statistics in a format that complies with the RMON MIB definition.

RMON Groups Supported

The Hardened Ethernet Extender Switch supports the following RMON MIB groups defined in RFC 2819:

•RMON Statistics Group— maintains use and error statistics for the Hardened

Ethernet Extender Switch port being monitored.

•RMON History Group—gathers and stores periodic statistical samples from the previous Statistics Group.
