RMON

When using the RMON features of the switch, you should note the
following:
After the default sessions are created, they have no special status. You
can delete or change them as required.
The greater the number of RMON sessions, the greater the burden on
the management resources of the switch. However, the forwarding
performance of the switch is not affected.

the following command:
