SNMP and RMON
This chapter describes the FS3-1600 Switchs Simple Network
Management Protocol (SNMP) and Remote Monitoring (RMON) capabilities. Topics include:
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 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 predefined 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.
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.
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.
When frame status messages are generated on the switching bus, a software driver running on the Switch Manager CPU automatically updates the FS3-1600 Switchs 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.
The FS3-1600 Switch supports the following RMON MIB groups de-fined in RFC1757:
The FS3-1600 Switch supports the following four groups of Bridge MIB (RFC1493):
