Chapter 24 Multicast
Table 63 Advanced Application > Multicast > Multicast Setting (continued)
LABEL | DESCRIPTION |
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 | The IP address range of 224.0.0.0 to 224.0.0.255 are reserved for |
Multicast Group | 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 |
| 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 |
| 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. |
| In normal leave mode, when the Switch receives an IGMP leave |
| message from a host on a port, the Switch waits for IGMP reports after |
| the multicast router sends out an IGMP |
| message to determine whether other hosts connected to the port |
| should remain in the specific multicast group. |
| 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. |
