Bridging – Multicast Addresses, Continued…
After adding a Multicast Group Address it will appear on the main list and will show the associated
ports that go along with that address.
Following the Delete button on the page above, the administrator will be presented with a list of
Multicast Group Addresses that are configured on the switch. Using the pull down menu the administrator
should select the desired port to be removed. Then click on the Delete button at the bottom of the page.
Note: If there are multiple ports on different VLANs, the 9000 will apply the static multicast address to
the lowest VLAN-ID that is associated with one of the ports assigned to the static multicast address.
So if the lowest VLAN-ID contains all the ports assigned to the static multicast address (an
umbrella VLAN), it will function for all those ports with no problems. This can be achieved with
overlapping VLANs.
