Figure 6-52. Setup IEEE 802.1Q Multicast Forwarding screen
When the switch is in Layer 2 operating mode, IEEE 802.1Q multicast forwarding allows the static entry of multicast MAC addresses, which will be sources of multicast packets, and switch port numbers, to which these multicast packets will be forwarded. The ports that can be chosen as the destination for multicast packets from the above MAC multicast address, are limited to the ports belonging to the VLAN that corresponds to the VID entered in the VID field.
Each port of a given VLAN can be configured as an egress member, a forbidden
ParameterDescription
Action:
<Add/Modify>
The field can be toggled between Add/Modify and Delete using the space bar. To add a new entry to the multicast forwarding table, select Add/Modify and enter the VID of the VLAN that will be receiving the multicast packets. Enter the MAC address of the multicast source, and then enter the member ports. Delete allows for the deletion of a previously made entry.
