4.7.7 Multicast Filter

In certain switch applications, the administrator may want to control the multicast services that are available to end users. For

example, an IP/TV service is based on a specific subscription plan. The multicast filtering feature fulfills this requirement by

restricting access to specified multicast services on a switch port.

Multicast filtering enables you to assign a profile to a switch port that specifies multicast groups that are permitted or denied on

the port. A multicast filter profile can contain one or more, or a range of multicast addresses; but only one profile can be

assigned to a port. When enabled, multicast join reports received on the port are checked against the filter profile. If a requested

multicast group is permitted, the multicast join report is forwarded as normal. If a requested multicast group is denied, the

multicast join report is dropped.

When you have created a Multicast profile number, you can then configure the multicast groups to filter and set the access

mode.

Command Usage

 Each profile has only one access mode; either permit or deny.

 When the access mode is set to permit, multicast join reports are processed when a multicast group falls within the

controlled range.

 When the access mode is set to deny, multicast join reports are only processed when the multicast group is not in the

controlled range.
