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