RMON
A typical RMON setup consists of the following two components:
•RMON probe — An intelligent, remotely controlled device or software agent that continually collects statistics about a LAN segment or VLAN. The probe transfers the information to a management workstation on request, or when a predefined threshold is crossed.
•Management workstation — Communicates with the RMON probe and collects the statistics from it. The workstation does not have to be on the same network as the probe, and can manage the probe by
RMON FEATURES OF THE SWITCH
The IETF defines nine groups of Ethernet RMON statistics. The Summit supports the following four of these groups:
•Statistics
•History
•Alarms
•Events
This section describes these groups, and discusses how they can be used.
STATISTICS
The RMON Ethernet Statistics group provides traffic and error statistics showing packets, bytes, broadcasts, multicasts, and errors on a LAN segment or VLAN.
Information from the Statistics group is used to detect changes in traffic and error patterns in critical areas of the network.
HISTORY
The History group provides historical views of network performance by taking periodic samples of the counters supplied by the Statistics group. The group features
The group is useful for analysis of traffic patterns and trends on a LAN segment or VLAN, and to establish baseline information indicating normal operating parameters.
