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
