Description 
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. 
 
  Caution: 
In local user view, before configuring this command, you must configure user service 
type as LAN-ACCESS, which the managed multicast supports exclusively at present. 
 
You can use the service-type lan-access command to configure service type in local 
user view. 
Related command: display local-user, service-type lan-access.
