multicast

Syntax
multicast ip-address [ ip-address &<1-9> | mask-length ]
undo multicast { ip-address [ ip-address &<1-9> ] | all }
View
Local user view
Parameter
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.
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.
