7.3.3 Remote Monitoring (RMON)
The IBM switches provide a Remote Monitoring (RMON) interface that allows network
devices to exchange network monitoring data. RMON allows the switch to perform the
following functions:
򐂰 Track events and trigger alarms when a threshold is reached.
򐂰 Notify administrators by issuing a syslog message or SNMP trap.
The RMON MIB provides an interface between the RMON agent on the switch and an RMON
management application. The RMON MIB is described in RFC 1757
(http://www.ietf.org/rfc/rfc1757.txt). The RMON standard defines objects that are
suitable for the management of Ethernet networks. The RMON agent continuously collects
statistics and proactively monitors switch performance. You can use RMON to monitor traffic
that flows through the switch.
The switch supports the following RMON Groups, as described in RFC 1757:
򐂰 Group 1: Statistics
򐂰 Group 2: History
򐂰 Group 3: Alarms
򐂰 Group 9: Events
RMON Group 1: Statistics
The switch supports collection of Ethernet statistics as outlined in the RMON statistics MIB,
referring to etherStatsTable. You can configure RMON statistics on a per-port basis. RMON
statistics are sampled every second, and new data overwrites any old data on a port.
Example configuration
Here is an example configuration:
1. Enable RMON on a port. To enable RMON on a port, run interface and rmon:
– RS8264(config)# interface port 1
– RS8264(config-if)# rmon
2. To view the RMON statistics, run interface, run rmon, and run show to show the inteface,
as shown in Example 7-18.
Example 7-18 View of the RMON statistics
RS8264(config)# interface port 1
RS8264(config-if)# rmon
RS8264(config-if)# show interface port 1 rmon-counters
------------------------------------------------------------------
RMON statistics for port 3:
etherStatsDropEvents: NA
etherStatsOctets: 7305626
etherStatsPkts: 48686
Important: RMON port statistics must be enabled for the port before you can view
RMON statistics.
