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. |
|
|
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. |
|
|
Leave Timeout | Enter an IGMP leave timeout value (from 1 to 16 711 450) in seconds. |
| 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 from a host. |
|
|
802.1p Priority | Select a priority level |
| outgoing IGMP control packets. Otherwise, select |
| 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 | Specify the action to perform when the Switch receives an unknown |
Multicast Frame | multicast frame. Select Drop to discard the frame(s). Select Flooding |
| to send the frame(s) to all ports. |
|
|
Reserved | Multicast addresses (224.0.0.0 to 224.0.0.255) are reserved for the |
Multicast Group | local scope. For examples, 224.0.0.1 is for all hosts in this subnet, |
| 224.0.0.2 is for all multicast routers in this subnet, etc. A router will not |
| forward a packet with the destination IP address within this range. See |
| the IANA website for more information. |
| 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. |

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 |
