111 | Captive Portal for Guest Access AOS-W Instant 6.3.1.1-4.0 | User Guide

Walled Garden

The administrators can also control the resources that the guest users can access and the amount of bandwidth or

air time they can use at any given time. When an external Captive portal is used, the administrators can configure a

walled garden, which determines access to the URLs requested by the guest users. For example, a hotel

environment where the unauthenticated users are allowed to navigate to a designated login page (for example, a

hotel website) and all its contents. The users who do not sign up for the Internet service can view only the “allowed”

Websites (typically hotel property Websites).

The administrators can allow or block access to specific URLs by creating a whitelist and blacklist. When the users

attempt to navigate to other Websites, which are not in the whitelist of the walled garden profile, the users are

redirected to the login page. If the requested URL is on the blacklist, it is blocked. If it appears on neither list, the

request is redirected to the external Captive portal.

Configuring a WLANSSID for Guest Access

You create an SSID for guest access by using the AOS-W Instant UI or CLI:

In the AOS-W Instant UI

1. In the Networks tab of the AOS-W Instant main window, click the New link. The New WLAN window is

displayed.

2. Enter a name that uniquely identifies a wireless network in the Name (SSID) text box.

3. Based on the type of network profile, specify the Primary usage as Guest.

4. Click the Show advanced options link. The advanced options for configuration are displayed.

5. Enter the required values for the following configuration parameters:

Parameters Description

Broadcast/Multicast Select any of the following values under Broadcast filtering:

l All—When set to All, the OAW-IAP drops all broadcast and multicast frames

except DHCP and ARP.

l ARP—When set to ARP, the OAW-IAP converts ARP requests to unicast and

send frames directly to the associated client.

l Disabled— When set to Disabled, all broadcast and multicast traffic is

forwarded.

DTIM interval

The DTIM interval indicates the delivery traffic indication message (DTIM) period

in beacons, which can be configured for every WLAN SSIDprofile. The

DTIMinterval determines how often the OAW-IAP should deliver the buffered

broadcast and multicast frames to associated clients in the powersave mode.

The default value is 1, which means the client checks for buffered data on the

OAW-IAP at every beacon. You can also configure a higher DTIM value for

power saving.

Multicast transmission

optimization

Select Enabled if you want the OAW-IAP to select the optimal rate for sending

broadcast and multicast frames based on the lowest of unicast rates across all

associated clients. When this option is enabled, multicast traffic can be sent at up

to 24 Mbps. The default rate for sending frames for 2.4 GHz is 1 Mbps and 5.0

GHz is 6 Mbps. This option is disabled by default.

Dynamic multicast optimization

Select Enabled to allow OAW-IAP to convert multicast streams into unicast

streams over the wireless link. Enabling Dynamic Multicast Optimization (DMO)

enhances the quality and reliability of streaming video, while preserving the

bandwidth available to the non-video clients.
