When using the RMON features of the Switch, 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. If you have many RMON
sessions, the forwarding performance of the Switch is not affected but
you may experience slow response times from the web interface.
You can define up to 200 alarms for the Switch. The events that you can
define for each alarm and their resulting actions are listed in
