RMON Features of
the Stack
Table 7-1 details the RMON support provided by the stack.
When using the RMON features of the stack, 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 stack 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 200,000 packets a second.

Statistics
A new or initialized stack has one Statistics session per port.
History
A new or initialized stack has two History sessions per port.
These sessions provide the data for the unit and port graphs of
the web interface:
■
30 second intervals, 10 historical samples stored
■
30 minute intervals, 10 historical samples stored
Alarms
Although up to 200 alarms can be defined for the stack, a new
or initialized stack has two alarms defined for each port:
■
Broadcast bandwidth used
■
Percentage of errors over one minute
You can modify these alarms using an RMON management
application, but you cannot create or delete them.
For more information about the alarms setup on the stack, see

sessions defined on a new or initialized stack.
Hosts Top N
