58 CHAPTER 7: STATUS MONITORING AND STATISTICS
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.
