Command Modes INTERFACE VLAN

Command History

Version 7.7.1.0 Introduced on the E-Series TeraScale.

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 mac-flood-

list command 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 the unicast MAC addresses when specifying MAC address ranges (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.

Commands

mac-flood-list – floods multicast frames with specified MAC addresses to all ports in a VLAN.
