EX2500 Ethernet Switch Configuration Guide

66  RMON Group 1—Statistics

RMON Group 1—Statistics

The switch supports collection of Ethernet statistics as outlined in the RMON

statistics MIB, in reference 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 given port.

Use the following procedure to configure RMON statistics:

1. Enable RMON on a port.

ex2500(config)# interface port 1

ex2500(config-if)# rmon enable

2. Configure the RMON statistics on a port.

ex2500(config)# interface port 1

ex2500(config-if)# rmon collection-stats 1

ex2500(config-if)# rmon collection-stats owner “port 1 rmon”

This configuration enables RMON statistics on port 1.

3. View RMON statistics for the port.

ex2500

(config)#

show rmon statistics
