This chapter describes how to configure Cisco VideoStream functionality on the controller. It contains these sections:

•Overview of the VideoStream

•Guidelines for Configuring VideoStream on the Controller

•Configuring VideoStream

Overview of the VideoStream

The IEEE 802.11 wireless multicast delivery mechanism does not provide a reliable way to acknowledge lost or corrupted packets. As a result, if any multicast packet is lost in the air, it is not sent again which may cause an IP multicast stream unviewable.

The VideoStream feature makes the IP multicast stream delivery reliable over the air, by converting the broadcast frame over the air to a unicast frame. Each VideoStream client acknowledges receiving a video IP multicast stream.

Guidelines for Configuring VideoStream on the Controller

Follow these guidelines when configuring VideoStream on the controller:

•The AP1100 and AP1200 do not support the reliable multicast feature.

•Make sure that the multicast feature is enabled. We recommend configuring IP multicast on the controller with multicast-multicast mode.

•Check for the IP address on the client machine. The machine should have an IP address from the respective VLAN.

•If there is a mismatch in the version of code on your controller, upgrade the controller code to 7.0.98.0 or later.

•Verify that the access points have joined the controllers.

•Make sure that the clients are able to associate to the configured WLAN at 802.11a/n speed.

•VideoStream is supported on the following access points: Cisco Aironet 3500, 1260, 1250, 1240AG, 1140, 1130AG, 1040

Configuring VideoStream

This section describes how to configure VideoStream on the controller. This section contains the following topics:

•Using the GUI to Configure the VideoStream on the Controller

•Using the CLI to Configure the VideoStream to the Controller

Using the GUI to Configure the VideoStream on the Controller

To configure the VideoStream on the controller using the controller GUI, follow these steps:

Note To enable the multicast feature using the controller GUI, perform Step 1 through Step 8.

Step 1 Choose WIRELESS > Media Stream > General to open the Media Stream > General page (see Figure 5-1).

Step 2 Select the Multicast Direct Feature check box to enable the multicast direct feature. 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.

Figure 5-1 Media Stream > General Page

Step 3 Under the Session Message Config, select Session announcement State to enable the session announcement mechanism. If this feature is enabled, clients are informed each time a controller is not able to serve the multicast direct data to the client.

Step 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.

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

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

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

Step 8 Click Apply to commit your changes.

Note To add a media stream using the controller GUI, perform Step 9 through Step 16.

Step 11 In the Stream Name text box, enter the media stream name. The stream name can be up to 64 characters.

Step 12 In the Multicast Destination Start IP Address text box, enter the start IP address of the multicast media stream.

Step 13 In the Multicast Destination End IP Address text box, enter the end IP address of the multicast media stream.

Step 14 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.

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

Step 15 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 500 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 BestEffort class on periodic reevaluation.

The default value is drop.
