Usage
Information
This command restricts flooding for all unknown multicast traffic on ports below a
certain speed. If you want some multicast traffic to be flooded on slower ports, use
the command
mac-flood-list without the min-speed option, in combination with
restrict-flooding. With mac-flood-list you specify the traffic you want to be flooded using
a MAC address range.
You may not use unicast MAC addresses when specifying MAC address ranges, and
do not overlap MAC addresses ranges, when creating multiple mac-flood-list entries
for the same VLAN. Restricted Layer 2 Flooding is not compatible with MAC
accounting or VMANs.
