DESCRIPTION
Select Active to enable IGMP filtering to control which IGMP groups a
subscriber on a port can join.
Note: If you enable IGMP filtering, you must create and assign
IGMP filtering profiles for the ports that you want to allow to
join multicast groups.
Specify the action to perform when the Switch receives an unknown
multicast frame. Select Drop to discard the frame(s). Select Flooding
to send the frame(s) to all ports.
The IP address range of 224.0.0.0 to 224.0.0.255 are reserved for
multicasting on the local network only. For example, 224.0.0.1 is for all
hosts on a local network segment and 224.0.0.9 is used to send RIP
routing information to all RIP v2 routers on the same network segment.
A multicast router will not forward a packet with the destination IP
address within this range to other networks. See the IANA web site for
more information.
The layer 2 multicast MAC addresses used by Cisco layer 2 protocols,
01:00:0C:CC:CC:CC and 01:00:0C:CC:CC:CD, are also included in this
group.
Specify the action to perform when the Switch receives a frame with a
reserved multicast address. Select Drop to discard the frame(s). Select
Flooding to send the frame(s) to all ports.
This field displays the port number.
Settings in this row apply to all ports.
Use this row only if you want to make some settings the same for all
ports. Use this row first to set the common settings and then make
adjustments on a port-by-port basis.
Note: Changes in this row are copied to all the ports as soon as
you make them.
Select this option to set the Switch to remove this port from the
multicast tree when an IGMP version 2 leave message is received on
this port.
Select this option if there is only one host connected to this port.
Enter an IGMP normal leave timeout value (from 200 to 6,348,800) in
miliseconds. Select this option to have the Switch use this timeout to
update the forwarding table for the port.
This defines how many seconds the Switch waits for an IGMP report
before removing an IGMP snooping membership entry when an IGMP
leave message is received on this port from a host.
Enter an IGMP fast leave timeout value (from 200 to 6,348,800) in
miliseconds. Select this option to have the Switch use this timeout to
update the forwarding table for the port.
This defines how many seconds the Switch waits for an IGMP report
before removing an IGMP snooping membership entry when an IGMP
leave message is received on this port from a host.
