Verifying VideoStream Configuration

A.

VideoStream is a feature on Cisco Wireless LAN Controllers (WLC) that helps to optimize the delivery of video traffic over a wireless network by reducing the impact of video traffic on other types of traffic. If users are not able to view company video broadcast over the wireless network, it is necessary to verify whether VideoStream is configured correctly and working as expected on the Cisco WLC.

To verify that VideoStream is configured and working in the Cisco WLC GUI, we can navigate to the Multicast Status page, which displays information about the multicast groups and their status. The following options are available to check the status of VideoStream on a Cisco WLC:

A. The Multicast Status shows "MediaStream Allowed" in the Multicast Group Details: This option confirms that the VideoStream feature is enabled on the WLC and the multicast groups are allowed to use the MediaStream feature. This is a necessary condition for VideoStream to work, but it does not necessarily mean that VideoStream is working correctly.

B. The Multicast Status shows "Multicast-direct Allowed" in the Multicast Group Details: This option confirms that the VideoStream feature is enabled on the WLC and the multicast groups are allowed to use the Multicast-direct feature. Multicast-direct is another feature that can be used to optimize the delivery of multicast traffic over a wireless network, but it is not specific to VideoStream.

C. The Multicast Status shows "MediaStream Ongoing" in the Client detail page: This option confirms that VideoStream is working correctly for a specific client device. If the client device is receiving video traffic over the wireless network and the multicast status shows "MediaStream Ongoing," it indicates that the WLC is correctly optimizing the delivery of video traffic for that device.

D. The Multicast Status shows "Normal Multicast" in the Multicast Group Details: This option confirms that VideoStream is not working correctly. "Normal Multicast" means that the WLC is not optimizing the delivery of multicast traffic and is treating it as regular multicast traffic.

In summary, the correct option to verify that VideoStream is configured and working correctly on a Cisco WLC is option A: The Multicast Status shows "MediaStream Allowed" in the Multicast Group Details. This confirms that the VideoStream feature is enabled on the WLC and the multicast groups are allowed to use the MediaStream feature, which is necessary for VideoStream to work. To verify that VideoStream is working correctly for specific client devices, we can check the multicast status in the Client detail page.
