VideoStream

Information about Media Stream

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 Media Stream feature makes the delivery of the IP multicast stream reliable over air, by converting the multicast frame to a unicast frame over the air. Each Media Stream client acknowledges receiving a video IP multicast stream.


Note

Support for IPv6 was added from Cisco IOS XE Gibraltar 16.12.1. You can use IPv6 multicast addresses in place of IPv4 multicast addresses to enable media stream on the IPv6 networks.

Prerequisites for Media Stream

  • Make sure that the Multicast feature is enabled. We recommend that you configure IP multicast on the controller in multicast-multicast mode.

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

  • Verify that the access points have joined the controllers .

How to Configure Media Stream

Configuring Multicast-Direct Globally for Media Stream (CLI)

Procedure

  Command or Action Purpose

Step 1

configure terminal

Example:

Device# configure terminal

Enters global configuration mode.

Step 2

wireless multicast

Example:

Device(config)# wireless multicast

Enables multicast for wireless forwarding.

Step 3

ip igmp snooping

Example:

Device(config)# ip igmp snooping

Enables IGMP snooping on a per-VLAN basis. If the global setting is disabled, then all the VLANs are treated as disabled, whether they are enabled or not.

Step 4

ip igmp snooping querier

Example:

Device(config)# ip igmp snooping querier

Enables a snooping querier on an interface when there is no multicast router in the VLAN to generate queries.

Step 5

wireless media-stream multicast-direct

Example:

(config)#wireless media-stream multicast-direct

Step 6

wireless media-stream message

Example:

(config)#wireless media-stream message ?
  Email  Configure Session Announcement Email
  Notes  Configure Session Announcement notes
  URL    Configure Session Announcement URL
  phone  Configure Session Announcement Phone number
  <cr>

Configures various message-configuration parameters such as phone, URL, email, and notes. That is, when a media stream is refused (due to bandwidth constraints), a message can be sent to the corresponding user. These parameters configure the messages that are to be sent to the IT support email address, notes (message be displayed explaining why the stream was refused), URL to which the user can be redirected, and the phone number that the user can call about the refused stream.

Step 7

wireless media-stream group name startIp endIp

Example:

(config)#wireless media-stream  group grp1 231.1.1.1 239.1.1.3  
  
    avg-packet-size Configure average packet size
    default Set a command to its defaults
    exit Exit sub-mode
    max-bandwidth Configure maximum expected stream bandwidth in Kbps
    no Negate a command or set its defaults
    policy Configure media stream admission policy
    priority Configure media stream priority, <1:Lowest - 8:Highest>
    qos Configure over the air QoS class, <'video'> ONLY
