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.

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. 

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:

¥

the SmartSwitch 2000 will reserve all bandwidth for switching; 

therefore, if all the bandwidth is needed for switching, management frames 
may be dropped.

¥

the management of the SmartSwitch 2000 may appear slow while 

the SmartSwitch 2000 is at maximum switching load.

¥

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.
