Information
When the mac-flood-list with the min-speed option is used in combination with the restrict-flood
command,
mac-flood-list command has higher priority than the restrict-flood command.
Therefore, all multicast frames matching the mac-address range specified using the
mac-flood-list command are flooded according to the mac-flood-list command. Only the
multicast frames not matching the mac-address range specified using the
mac-flood-list
command are flooded according to the
restrict-flood command.
