The SmartSwitch 2000 Chassis View
2-60 Managing the Hub
The value displayed as peak switch utilization will be reset to the current
value. The time and date will be reset to the current time and date. These
values will change only if a peak is experienced after this reset, or if you reset
this value again.
CPU Management Reservation:
Displays the desired amount of CPU bandwidth reserved for management
purposes: none, limited, or full. Bandwidth that is not reserved for management
will be devoted to switching.
Reserving CPU Bandwidth
Depending on your needs and the main function of your SmartSwitch 2000 you
may wish to change the amount of CPU bandwidth that is currently reserved for
management purposes. The three possible allocations of CPU bandwidth on your
SmartSwitch 2000 are:
¥ none Ñ the SmartSwitch 2000 will reserve all bandwidth for switching;
therefore, if all the bandwidth is needed for switching, management frames
may be dropped.
¥ limited Ñ the management of the SmartSwitch 2000 may appear slow while
the SmartSwitch 2000 is at maximum switching load.
¥ full Ñ management of the SmartSwitch 2000 is always possible and
management frames will have priority over switched data if full CPU
bandwidth is required (switched frames may be dropped).
To conÞgure the CPU Management Reservation:
1. Next to the CPU Management Reservation field click on and select none,
full, or limited from the drop down list that will appear.
2. Click on the Apply button to set the new CPU management reservation. A
window will appear stating the set was successful.

NOTE
The default setting for this Þeld is No. While No is selected the peak switch utilization
value will not be reset when you click on the Apply button. You must choose Yes for a
