CoS Interface Configuration Commands
Beginning in Privileged Exec mode, use the following commands in to
configure the traffic shaping and WRED exponent values for an interface.
Interface Queue Configuration
Beginning in Privileged Exec mode, use the following commands in to
configure and view CoS interface queue settings.
CLI Command Description
configure Enter Global Configuration mode.
interface
interface
Enter Interface Configuration mode, where
interface
is replaced by gigabitethernet
unit/slot/port
,
tengigabitethernet
unit/slot/port
, or port-channel
port-channel number
.
traffic-shape
bw
kbps Sets the upper limit on how much traffic can leave a
port. The
bw
variable represents the shaping
bandwidth value from 64 to 4294967295 kbps.
random-detect exponential-
weighting-constant
exponent
Configure the WRED decay exponent (range: 0–15)
for the interface. The weighting constant exponent
determines how much of the previous average queue
length sample is added to the current average queue
length. A value of 0 indicates that no weight is given
to the previous sample and only the instantaneous
rate is used. A value of 1 indicates that 1/2 of the
difference between the instantaneous value and the
previous value is added to the current value; a value of
2 implies that 1/4 of the difference is added, 3 implies
1/8 of the difference is added, etc.
