Complete these steps in order to configure bandwidth settings for a role:

Choose Device Management > CCA Servers > Manage [CAS_IP] > Filter > Roles > Bandwidth
in order to enable bandwidth management on the CAS.

1. 

Select Enable Bandwidth Management and click Update.

2. 

Choose User Management > User Roles > Bandwidth and click the Edit button next to the role for
which you want to set bandwidth limitations. The Bandwidth form appears as this example shows:

Note: Alternatively, you can go to User Management > User Roles > List of Roles and click the
BW button next to the role.

3. 

Set the maximum bandwidth in kilobits per second for upstream and downstream traffic in Upstream
Bandwidth and Downstream Bandwidth. Upstream traffic moves from the untrusted to the trusted
network, and downstream traffic moves from the trusted to the untrusted network.

4. 

Enter a Burstable Traffic level from 2 to 10 in order to allow brief (one second) deviations from the
bandwidth limitation. A Burstable Traffic level of 1 has the effect of disabling bursting.

The Burstable Traffic field is a traffic burst factor used to determine the capacity of the bucket. For
example, if the bandwidth is 100 Kbps and the Burstable Traffic field is 2, then the capacity of the
bucket is 100 Kb*2=200 Kb. If a user does not send any packets for awhile, the user has at most 200
