restrict-flooding
Prevent Layer 2 multicast traffic from being flooded on ports below a specified link speed.
E-Series TeraScale
Syntax
restrict-flooding multicast min-speed min-speed
Parameters
min-speed
min-
speed
Enter the minimum link speed that a port must have to receive flooded
multicast traffic. The range is 1000.
Defaults none
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.
