OmniSwitch 6250 CLI Reference Guide November 2009 page 20-23
interfaces flood rate
Configures the peak flood rate value for the specified interface.
interfaces slot[/port[-port2]] flood rate Mbps
Syntax Definitions
slot Slot number you want to configure.
port Port number of the interface you want to configure.
port2 Last port number in a range of ports you want to configure.
Mbps Peak flood rate, in megabits per second (Mbps). Valid ranges:
0–10 for 10 Mbps
0–100 for 100 Mbps
0–1000 for Gigabit Ethernet
Defaults
Platforms Supported
OmniSwitch 6250
Usage Guidelines
• Although you can configure a flood rate equal to the line speed you should not do so. Alcatel-Lucent
recommends that you always configure the flood rate to be less than the line speed.
• You can only configure one slot at a time. Repeat the command to configure additional slots.
• The interfaces flood rate command configures a maximum ingress flood rate value for an interface.
This peak flood rate value is applied to flooded (unknown destination address, broadcast) and multi-
cast traffic combined. For example, if an interface is configured with a peak flood rate of 50 Mbps, the
50 Mbps limit is shared by all traffic types.
• To specify the type of traffic eligible for rate limiting on an interface, use the interfaces flood rate and
interfaces flood multicast commands. By default, rate limiting applies only to flooded traffic.
• The flood rate can only be accurately configured for 512-byte packets. The flood rate cannot be accu-
rately set for smaller or larger sized packets. The accuracy/resolution is limited because the switch
makes an internal assumption of packet size when it converts bits/seconds to packets/seconds for the
hardware.
