 Note:
z The rmon alarm and rmon prialarm commands take effect on existing nodes only.
z For each port, only one RMON statistics entry can be created. That is, if an RMON statistics
entry is already created for a given port, you will fail to create another statistics entry with a
different index for the same port.

2.4 RMON Configuration Example
1. Network requirements
z The switch to be tested is connected to a remote NMS through the Internet. Ensure that the
SNMP agents are correctly configured before performing RMON configuration.
z Create an entry in the extended alarm table to monitor the information of statistics on the
Ethernet port, if the change rate of which exceeds the set threshold, the alarm events will be
triggered.
