RMON 5-27
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 Switch 1000 can forward a very large volume
of packets per second. The Statistics RMON
group is able to monitor every packet, but the
other groups sample a maximum of 6000 packets
a second.
■ The greater the number of RMON sessions, the
greater the burden on the management resources
of the Switch; however, the forwarding perfor-
mance of the Switch is not affected.
