History
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.
