For example, if clients are connected to the controller through a DSL line, you may want to restrict the upstream
bandwidth rate allowed for
each
user to 128 Kbps. Or, you can limit the
total
downstream bandwidth used by all
users in the ‘guest’ role to 128 Mbps. The following example configures a bandwidth rate of 128 Kbps and applies it
to upstream traffic for the previously-configured ‘web-guest’ user role on a per-user basis.
Configuring a Bandwidth Contract in the WebUI
In the WebUI, you can first configure a bandwidth contract and then assign it to a user role:
1. Navigate to the Configuration > Advanced Services > Stateful Firewall > BW Contracts page.
2. Click Add to create a new contract.
3. In the Contract Name field, enter BC512_up.
4. The Bandwidth field allows you to define a bandwidth rate in either kbps or Mbps. For this example, enter 512
in the Bandwidth field, then click the drop-down list and select kbps.
5. Click Done.
Assigning a Bandwidth Contract to a User Role in the WebUI
Now that you have a defined bandwidth contract, you can assign that contract to a user role.
1. Navigate to the Configuration > Security > Access Control > User Roles page.
2. Select Edit for the web-guest user role.
3. Under Bandwidth Contract, select BC512_up from the drop-down menu for Upstream.
4. Select Per User.
5. Scroll to the bottom of the page, and click Apply.
You can also can configure the user role and create the bandwidth contract from the User Roles page:
1. Navigate to the Configuration > Security > Access Control > User Roles page.
2. Select Edit for the web-guest user role.
3. In the Bandwidth Contract section, click the Upstream drop-down list and select Add New. The New Bandwidth
Contract fields appear.
a. In the Name field, enter BC512_up.
b. In the Bandwidth field, enter 512.
c. Click the Bandwidth drop-down list and select kbps.
d. Click Done to add the new contract and assign it to the role. The New Bandwidth Contract section closes.
4. In the Bandwidth Contract section, select the Per User checkbox.
5. Scroll to the bottom of the page, and click Apply.

Bandwidth Contract Exceptions
Bandwidth contracts on a VLAN can limit broadcast and multicast traffic. ArubaOS includes an internal exception
list to allow broadcast and multicast traffic using the VRRP, LACP, OSPF, PVST and STP protocols. To remove
per-vlan bandwidth contract limits on an additional broadcast or multicast protocol, add the MAC address for that
broadcast/multicast protocol to the Vlan Bandwidth Contracts MAC Exception List.
