Configuring the SSM channel table
The SSM channel table consists of entries that map groups to their sending source. SSM channels cannot conflict with static source groups and vice versa. When you configure an SSM channel or a static source group, the switch performs a consistency check to make sure there are no conflicts. You cannot map one group (G) to different sources for both a static source group and an SSM channel.
The consistency check mentioned above applies to all SSM channel entries, even if they are disabled. Disabling an entry means that it becomes inactive. It does not delete the entry, and you can re-enable it at any time.
When you disable an SSM channel, the Passport 8600 stops any multicast traffic from the specified source to the specified group. If desired, you can use this static setting as a security feature to block traffic from a certain source to a specific group.
For more information, refer to "Configuring multicast static source groups."
