Purpose Used to configure the multicast port filtering.
Syntax config multicast port_filtering_mode [<portlist>|all]
[forward_all_groups|forward_unregistered_groups
| filter_unregistered_groups]
Description This command configures the multicast filtering
and forwarding for specified ports.
Parameters
<portlist> − Specifies a range of ports to be
configured. The port list is specified by listing the
lowest switch number and the beginning port
number on that switch, separated by a colon.
Then the highest switch number, and the highest
port number of the range (also separated by a
colon) are specified. The beginning and end of the
port list range are separated by a dash. For
example, 1:3 specifies switch number 1, port 3.
2:4 specifies switch number 2, port 4. 1:3-2:4
specifies all of the ports between switch 1, port 3
and switch 2, port 4 − in numerical order.
forward_all_groups – The groups of ports
specified in the <portlist> are instructed to forward
all multicast packets, i.e. no filtering takes places
since multicast packets from unregistered and
registered multicast groups are forwarded in the
specified port group.
forward_unregistered_groups - The groups of
ports specified in the <portlist> are instructed to
forward only multicast packets from unregistered
multicast groups. Multicast packets from
registered groups are dropped.
filter_unregistered_groups - The groups of ports
specified in the <portlist> are instructed to filter all
multicast packets from unregistered multicast
groups. Multicast packets from registered groups
are forwarded.
