SmartStack STS16-20RM/STS16-20FRM Token Ring Switches, P/N: 9032957-01 Switch Overview
RMON Support
RMON is an industry-standard method for providing network statistics monitoring
using SNMP. It also collects fault, performance, and configuration statistics. It can
monitor continuously, even when communication with the management station is
not possible or efficient. RMON can then notify the management station when an
exceptional condition occurs.
In typical SNMP management, the SNMP client has to continuously poll the switch
for fault, performance, and configuration information, waiting for the value to
change. This causes increased traffic through the network. With RMON, you can
have the switch monitor a particular statistic internally, and when the statistics
reaches a threshold, the switch will send a trap to the client. This monitoring
method reduces traffic between the SNMP client and the switch.
The switch implements a mini RMON probe for the physical ports by supporting
some of the RMON groups RFC 1757 and RFC 1513.
For full RMON an external probe must be used.
