ANAGEMENT
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 3000 TX 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.
