Step 5 Configure the receiving interface on the PC.
Alpha-A28E(config)#interface port 3
Alpha-A28E(config-port)#mvr type receiver

Alpha-A28E(config-port)#switchport trunk native vlan 13
Alpha-A28E(config-port)#switchport trunk untagged vlan 3
Checking result
Check whether IGMP filtering is correctly configured on the interface.

5.7.4 Example for applying IGMP filtering and maximum multicast
group number to the VLAN
Networking requirements
Enable IGMP filtering on the switch. Add filtering rules in the VLAN to filter multicast users.
As shown below,
Create an IGMP filtering rule Profile 1, set the action to pass for the multicast group
ranging from 234.5.6.7 to 234.5.6.10.
Apply filtering IGMP filtering rule Profile 1 on VLAN 12, allow the set top box to join
the 234.5.6.7 multicast group, forbid it to join the 234.5.6.11 multicast group.
Apply no filtering rule on VLAN 3, and allow PCs to join the 234.5.6.11 multicast group.
Configure the maximum multicast group number in VLAN 12. After the set top box is added
to the 234.5.6.7 multicast group, add it to the 234.5.6.8 multicast group. Then, it quits the
234.5.6.7 multicast group.
