Oversubscribing Physical and Virtual Links
Purpose
(Optional) Configures traffic policing on the basis of a
percentage of bandwidth available on an interface.
(Optional) cir is the committed information rate (CIR) and
indicates an average rate at which the policer meters traffic.
percent percent indicates to use the percentage of available
bandwidth specified in percent to calculate the CIR.
bc normal-burst-in-msec specifies the normal or committed
burst size (CBS) that the first token bucket uses for policing
traffic. Specify the normal-burst-in-msec value in
milliseconds (ms). Valid values are from 1 to 2000. The
default value is the greater of 2 ms worth of bytes at the
police rate or the network minimum transmission unit
(MTU).
be excess-burst-in-msec specifies the excess burst size
(EBS) that the second token bucket uses for policing traffic.
Specify the excess-burst-in-msec value in milliseconds
(ms). Valid values are from 1 to 2000. The default value is
zero (0). You must specify normal-burst-in msec before you
specify excess-burst-in-msec.
Burst in milliseconds is based on the policing
Note
committed information rate (CIR).
conform-action action is the action to take on packets that
conform to the rate limit. The default action is transmit. You
must specify burst-excess before you specify the
conform-action.
exceed-action action is the action to take on packets that
exceed the rate limit, but not the PIR. The default action is
drop. You must specify the conform-action before you
specify the exceed-action.
(Optional) violate-action action is the action to take on
packets that continuously exceed the PIR rate limit. The
default action is the same as the exceed-action. You must
specify the exceed-action before you specify the
violate-action.
