■

The rmon alarm and rmon prialarm commands take effect on existing nodes 
only.

■

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.

After the above configuration, you can execute the display command in any view 
to display the RMON running status, and to verify the configuration.

■

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.

■

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.
