To verify the configuration, first use the IP/TV Viewer client to request the stream at the branch office. Then use the show ip mroute active command. The following example shows the low stream (100k).
show ip mroute active

QoS for IP/TV Server
Although this document does provide full details on the QoS features and configurations for IP/TV, a basic recommendation and example configuration is given for reference.
The recommended QoS guidelines for IP/TV are: Classify streaming media with a DSCP of CS4 (which maps, by default, to a COS of 4).
Configure the ingress port on the switch that connects to the IP/TV server to “tag” the streaming media with the recommended value of CoS=4. The IP/TV server will require a 801.2Q trunk connection.
