Configuring QoS
Command
Purpose
1.
configure terminal
Enter global configuration mode.
2.
policy-map
policy-map-name
Create a policy map by entering the policy map name, and enter
policy-map configuration mode. By default, no class maps are
defined.
3.
class
{
class-map-name
|
class-default
}
Enter a class-map name or
class-default
to match all unclassified
packets, and enter policy-map class configuration mode.
If you enter a class-map name, you must have already created the
class map by using the
class-map
global configuration command.

]]
Define a policer using one or two rates—committed information rate
(CIR) and peak information rate (PIR) for the class of traffic.
By default, no policer is defined.
For
rate-bps,
specify average traffic rate in bits per second
(bps). The range is 8000 to 1000000000.
For
cir
cir-bps,
specify a committed information rate at which
the bc token bucket is updated in bits per second (b/s). The
range is 8000 to 1000000000.
For
burst-bytes
(optional)
,
specify the normal burst size in
bytes. The range is 8000 to 1000000.
(Optional) For
bc
conform-burst,
specify the conformed burst
used by the bc token bucket for policing.The range is 8000 to
1000000 bytes.
(Optional) For
pir
pir-bps,
specify the peak information rate at
which the be token bucket for policing is updated. The range is
8000 to 1000000000 b/s. If you do not enter a
pir
pir-bps
, the
policer is configured as a 1-rate, 2-color policer.
For
be
peak-burst
, specify the peak burst size used by the be
token bucket. The range is 8000 to 1000000 bytes. The default
is internally calculated based on the user configuration.
