Assigning Bandwidth Contracts to User Roles
The administrators can manage bandwidth utilization by assigning either maximum bandwidth rates, or
bandwidth contracts to user roles. The administrator can assign a bandwidth contract configured in Kbps to
upstream (client to the W-IAP) or downstream (W-IAP to clients) traffic for a user role. The bandwidth contract
will not be applicable to the user traffic on the bridged out (same subnet) destinations. For example, if clients
are connected to an SSID, you can restrict the upstream bandwidth rate allowed for each user to 512 Kbps.
By default, all users that belong to the same role share a configured bandwidth rate for upstream or
downstream traffic. The assigned bandwidth will be served and shared among all the users. You can also assign
bandwidth rate per user to provide every user a specific bandwidth within a range of 1–65,535 Kbps. If there is
no bandwidth contract specified for a traffic direction, unlimited bandwidth is allowed.
In the earlier releases, bandwidth contract could be assigned per SSID. In the current release, the bandwidth
contract can also be assigned for each SSID user. If the bandwidth contract is assigned for an SSID in the
Instant 6.2.1.0-3.4.0.0 version, and when the W-IAP is upgraded to Instant 6.5.1.0-4.3.1.0 release version,
the bandwidth configuration per SSID will be treated as a per-user downstream bandwidth contract for that
SSID.
In the Instant UI
1. Click the Security link located directly above the Search bar in the Instant main window. The Security
window is displayed.
2. Click the Roles tab. The Roles tab contents are displayed.
3. Create a new role (see Creating a User Role on page 195) or select an existing role.
4. Under Access Rules, click New. The New Rule window is displayed.
5. Select Bandwidth Contract from the Rule Type drop-down list.
6. Specify the downstream and upstream rates in Kbps. If the assignment is specific for each user, select the
Peruser check box.
7. Click OK.
8. Associate the user role to a WLANSSID or a wired profile.
You can also create a user role and assign bandwidth contracts when configuring an SSID or a wired profile.
In the CLI:
To assign a bandwidth contract in the CLI:
(Instant AP)(config)# wlan access-rule <name>
(Instant AP) (Access Rule <name>)# bandwidth-limit {downstream <kbps>|upstream <kbps>|peruser
{downstream <kbps>| upstream <kbps>}}
(Instant AP) (Access Rule <name>)# end
(Instant AP) # commit apply
To associate the access rule to a wired profile:
(Instant AP)(config)# wired-port-profile <name>
(Instant AP)(wired ap profile <name>)# access-rule-name <access-rule-name>
(Instant AP)(wired ap profile <name>)# end
(Instant AP) # commit apply
