Policy-Map Commands
12-90 Configuring Quality of Service
Example
The
following
example
defines
a
traffic
class
using
the
class-map
command
and
match
criteria
from
the
traffic
class
with
the
Traffic
Policing
configuration,
which
is
configured
in
the
service
policy
using
the
policy-map
command.
The
service-policy
command
is
then
used
to
attach
this
service
policy
to
the
interface.
In
this
example,
traffic
policing
is
configured
with
the
average
rate
of
8000
bits
per
second
and
the
normal
burst
size
at
1200
bytes
and
an
excess
burst
of
2000
bytes
for
all
packets
leaving
F1/0
:
XSR(config)#class-map access-match
XSR(config-cmap<access-match>)#match access-group 1
XSR(config)#policy-map police-setting
XSR(config-pmap<police-setting>)#class access-match
XSR(config-pmap-c<access-match>)#police 8000 1200 2000 conform-action transmit
exceed-action drop
XSR(config>)interface fastethernet 1/0
XSR(config-if<F1>)#service-policy output police-setting
priority
This
command
gives
priority
to
a
class
of
traffic
belonging
to
a
policy
map.
It
configures
low
latency
queueing,
providing
strict
Priority
Queues
(PQ)
over
Class
‐
based
Weighted
Fair
Queueing
(CBWFQ).
Strict
PQ
allows
delay
‐
sensitive
data
such
as
voice
to
be
de
‐
queued
and
sent
before
packets
in
other
queues
are
dequeued.
The
burst
argument
specifies
the
burst
size
and,
as
such,
configures
the
network
to
accommodate
temporary
bursts
of
traffic.
The
default
burst
value,
which
is
computed
as
1
second
of
traffic
at
the
configured
bandwidth
rate,
is
used
when
the
burst
argument
is
not
specified.
Priority
queues
can
be
reserved
by
absolute
bandwidth
with
these
settings:
high,
medium,
low
and
normal
.
Syntax
priority
priority-level
bandwidth-kbps
[
burst
]
Syntax of the “no” Form
Remove
a
previously
specified
priority
specified
for
a
class
with
the
no
form
of
this
command:
no priority
Note:
The
bandwidth
and
priority
commands cannot be used in the same
class
, within the
same policy map, but they can be used together in the same
policy map
. They cannot be configured
for
class-default
. Class-default is always defined as fair queue.
priority level
Specifies
the
priority
queue:
high
,
medium
,
low
or
normal
.
Normal
priority
has
the
least
precedence.
bandwidth-kbps
Guaranteed
allowed
bandwidth
for
priority
traffic.
Beyond
the
guaranteed
bandwidth,
priority
traffic
will
be
dropped
to
ensure
that
non
‐
priority
traffic
is
not
starved.
Range:
1
to
100,000
kbps.
burst
Sets
the
burst
size,
ranging
from
32
to
2,000,000
bytes.
