Chapter 23 Multicast The following table describes the labels in this screen. Table 56 Advanced Application > Multicast > Multicast Setting LABEL DESCRIPTION IGMP Snooping Use these settings to configure IGMP Snooping. Active Select Active to enable IGMP Snooping to forward group multicast traffic only to ports that are members of that group. Querier Select this option to allow the Switch to send IGMP General Query messages to the VLANs with the multicast hosts attached. Host Timeout Specify the time (from 1 to 16,711,450) in seconds that elapses before the Switch removes an IGMP group membership entry if it does not receive report messages from the port. 802.1p Priority Select a priority level (0-7) to which the Switch changes the priority in outgoing IGMP control packets. Otherwise, select No-Change to not replace the priority. IGMP Filtering Select Active to enable IGMP filtering to control which IGMP groups a subscriber on a port can join. Unknown Multicast Frame Reserved Multicast Group Port * 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. Immed. Leave Normal Leave Fast Leave Group Limited 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. Select this option to limit the number of multicast groups this port is allowed to join. 172 GS2200-8/24 User's Guide

LABEL
DESCRIPTION
IGMP Snooping
Use these settings to configure IGMP Snooping.
Active
Select
Active
to enable IGMP Snooping to forward group multicast traffic only to ports
that are members of that group.
Querier
Select this option to allow the Switch to send IGMP General Query messages to the VLANs
with the multicast hosts attached.
Host Timeout
Specify the time (from 1 to 16,711,450) in seconds that elapses before the Switch
removes an IGMP group membership entry if it does not receive report messages from
the port.
802.1p Priority
Select a priority level (0-7) to which the Switch changes the priority in outgoing IGMP
control packets. Otherwise, select
No-Change
to not replace the priority.
IGMP Filtering
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.
Unknown
Multicast Frame
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.
Reserved
Multicast Group
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.
Port
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.
Immed. Leave
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.
Normal Leave
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.
Fast Leave
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.
Group Limited
Select this option to limit the number of multicast groups this port is allowed to join.
