undo multicast { ip-address [ ip-address &<1-9> ] | all }

Local user view

ip-address &<1-9>: Multicast group IP address. &<1-9> implies that the preceding 
parameter can repeatedly input up to 9 times.

mask-length: Mask length. The default value of this argument is to 32. If you do 
not specify this argument, this command specifies a specific multicast group 
instead of a network segment.

Use the multicast command to configure the multicast groups so that users can 
join the multicast group (the managed multicast).

Use the undo multicast command to remove the configuration.

If you do not specify the mask-length argument, you can configure up to ten 
multicast group addresses at one time. And if you specify the mask-length 
argument, you can configure only one multicast group address at one time. You 
can configure up to 64 network segments.

Managed multicast is based on the port mode. It implements authority control for 
users to a multicast group. Users must pass the 802.1x authentication for the port 
first. Moreover, users can only join the multicast group configured particularly for 
them. The port-based managed multicast prohibits users without authority from 
joining, controlling users’ access to the specific multicast group.

You can use the service-type lan-access command to configure service type in 
local user view.
