www.dell.com | support.dell.com restrict-flooding et Prevent Layer 2 multicast traffic from being flooded on ports below a specified link speed. Syntax restrict-flooding multicast min-speed speed Parameters min-speed min-speed Enter the minimum link speed that a port must have to receive flooded multicast traffic. Range: 1000 Defaults None Command Modes INTERFACE VLAN Command History Usage Information Version 7.7.1.0 Introduced on E-Series TeraScale 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. Related Commands mac-flood-list Flood multicast frames with specified MAC addresses to all ports in a VLAN. show ip mroute c e s View the Multicast Routing Table.
