max-ratio: Enter the broadcast suppression ratio for the current VLAN as a
percentage, in the range 0 to 100. The smaller the percentage, the less broadcast
traffic is allowed through the VLAN. If you do not want to perform broadcast
suppression on the VLAN, enter 100.
Description
■ Use the broadcast-suppression command to limit the amount of broadcast
traffic passing through a VLAN. When the traffic exceeds the specified
percentage, the system will drop packets to guarantee the network service and
reduce the broadcast traffic to a manageable limit.
■ Use the undo broadcast-suppression command to restore the default ratio
of 100, that is, no broadcast suppression.
Related Command: display vlan.
