Configure the multicast feature by following these steps:

1. Choose Wireless > MediaStream > General.

2. Select or unselect the Multicast Direct feature check box. The default value is disabled.

   Note	Enabling the multicast direct feature does not automatically reset the existing client state. The wireless clients must rejoin the multicast stream after enabling the multicast direct feature on the controller.

3. In the Session Message Config area, select Session announcement State check box to enable the session announcement mechanism. If the session announcement state is enabled, clients are informed each time a controller is not able to serve the multicast direct data to the client.

4. In the Session announcement URL text box, enter the URL where the client can find more information when an error occurs during the multicast media stream transmission.

5. In the Session announcement e-mail text box, enter the e-mail address of the person who can be contacted.

6. In the Session announcement Phone text box, enter the phone number of the person who can be contacted.

7. In the Session announcement Note text box, enter a reason as to why a particular client cannot be served with a multicast media.

8. Click Apply.

Add a media stream by following these steps:

1. Choose Wireless > Media Stream > Streams to open the Media Stream page.

2. Click Add New to configure a new media stream. The Media Stream > New page appears.

   Note	The Stream Name, Multicast Destination Start IP Address (IPv4 or IPv6), and Multicast Destination End IP Address (IPv4 or IPv6) text boxes are mandatory. You must enter information in these text boxes.

3. In the Stream Name text box, enter the media stream name. The stream name can be up to 64 characters.

4. In the Multicast Destination Start IP Address (IPv4 or IPv6) text box, enter the start (IPv4 or IPv6) address of the multicast media stream.

5. In the Multicast Destination End IP Address (IPv4 or IPv6) text box, enter the end (IPv4 or IPv6) address of the multicast media stream.

   Example:

   Note	Ensure that the Multicast Destination Start and End IP addresses are of the same type, that is both addresses should be of either IPv4 or IPv6 type.

6. In the Maximum Expected Bandwidth text box, enter the maximum expected bandwidth that you want to assign to the media stream. The values can range between 1 to 35000 kbps.

   Example:

   Note	We recommend that you use a template to add a media stream to the controller.

7. From the Select from Predefined Templates drop-down list under Resource Reservation Control (RRC) Parameters, choose one of the following options to specify the details about the resource reservation control:

   • Very Coarse (below 300 kbps)

   • Coarse (below 500 kbps)

   • Ordinary (below 750 kbps)

   • Low (below 1 Mbps)

   • Medium (below 3 Mbps)

   • High (below 5 Mbps)

     Note	When you select a predefined template from the drop-down list, the following text boxes under the Resource Reservation Control (RRC) Parameters list their default values that are assigned with the template.

   • Average Packet Size (100-1500 bytes)—Specifies the average packet size. The value can be in the range of 100 to 1500 bytes. The default value is 1200.

   • RRC Periodic update—Enables the RRC (Resource Reservation Control Check) Periodic update. By default, this option is enabled. RRC periodically updates the admission decision on the admitted stream according to the correct channel load. As a result, it may deny certain low priority admitted stream requests.

   • RRC Priority (1-8)—Specifies the priority bit set in the media stream. The priority can be any number between 1 and 8. The larger the value means the higher the priority is. For example, a priority of 1 is the lowest value and a value of 8 is the highest value. The default priority is 4. The low priority stream may be denied in the RRC periodic update.

   • Traffic Profile Violation—Specifies the action to perform in case of a violation after a re-RRC. Choose an action from the drop-down list. The possible values are as follows:

     Drop—Specifies that a stream is dropped on periodic revaluation.

     Fallback—Specifies that a stream is demoted to Best Effort class on periodic reevaluation.

     The default value is drop.

8. Click Apply.

5. In the Client Minimum Phy Rate text box, enter the minimum transmission data rate to the client. If the transmission data rate is below the phy rate, either the video will not start or the client may be classified as a bad client. The bad client video can be demoted for better effort QoS or subject to denial.
