Bridging – Multicast Addresses
The Multicast Addresses tab under the Bridging category will display a list of Multicast Group Addresses
that are associated with respective port numbers. This may be used to statically assign a Multicast Group
Address access to a group of ports on the switch.
Following the Add button on the page above, the administrator must enter a valid Multicast Group Address
and associate it with a port number or list on the switch. Once the administrator clicks on the Add button,
the changes will take effect instantly.
Note: If there are multiple ports on different VLANs, the 709FX 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.
