SNMP and RMON

This chapter describes the FS3-1600 Switch’s Simple Network

Management Protocol (SNMP) and Remote Monitoring (RMON) capabilities. Topics include:


Overview

RMON is an abbreviation for the Remote Monitoring MIB (Management Information Base). RMON is a system defined by the Internet Engineering Task Force (IETF) documents RFC 1271 and RFC 1757, which define how networks can be monitored remotely. RMONs typically consist of two components: an RMON probe and a management workstation:

The FS3-1600 Switch provides RMON capabilities that allow network administrators to set parameters and view statistical counters defined in MIB-II, Bridge MIB, and RMON MIB. RMON activities are performed at a Network Management Station running an SNMP network management application with graphical user interface.


SNMP Agent and MIB-2 (RFC1213)

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

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 FS3-1600 Switch supports a complete implementation of SNMP Agent and MIB-2.


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

When frame status messages are generated on the switching bus, a software driver running on the Switch Manager CPU automatically updates the FS3-1600 Switch’s RMON and other hardware-related MIB-counters. A local SNMP Agent and a remote SNMP Network Management Station using the SNMP protocol can then manipulated these counters.


RMON Groups Supported

The FS3-1600 Switch supports the following RMON MIB groups de-fined in RFC1757:


Bridge Groups Supported

The FS3-1600 Switch supports the following four groups of Bridge MIB (RFC1493):
