8.2 SNMP Agent and MIB-2 (RFC1213)

The SNMP Agent running on the Switch manager CPU is responsible for:

 Retrieving MIB counters from various layers of software modules according to the SNMP

GET/GET NEXT frame messages.

 Setting MIB variables according to the SNMP SET frame message.

 Generating an SNMP TRAP frame message to the Network Management Station if the threshold

of a certain MIB counter is reached or if other trap conditions (such as the following) are met:

- Warm start - Authentication failure

- Cold start - Rising alarm

- Link up - Falling alarm

- Link down - Topology change

MIB-2 defines a set of manageable objects in various layers of the TCP/IP protocol suites. MIB-2

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 Switch supports a complete implementation of

SNMP Agent and MIB-2.

8.3 RMON MIB (RFC 1757) and Bridge MIB (RFC 1493)

RMON is an abbreviation for the Remote Monitoring MIB (Management Information Base). RMON is a

system defined by the Internet Engineering Task Force (IETF) document RFC 1757, which defines how

networks can be monitored remotely.

RMONs typically consist of two components: an RMON probe and a management workstation:

 The RMON probe is an intelligent device or software agent that continually collects statistics about

a LAN segment or VLAN. The RMON probe transfers the collected data to a management

workstation on request or when a pre-defined threshold is reached.

 The management workstation collects the statistics that the RMON probe gathers The workstation

can reside on the same network as the probe, or it can have an in-band or out-of-band connection

to the probe.
