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.
