Incompatibilities

Mark IP Precedence, Police (all forms)

mark ip-precedence

This command marks all packets for the associated traffic stream with the specified IP Precedence

value. The IP Precedence value is an integer from 0 to 7.

Format

mark ip-precedence <0-7>

Mode

Policy-classmap Config

Policy Type

Incompatibilities

Mark IP DSCP, Police (all forms)

police-simple

This command is used to establish the traffic policing style for the specified class. The simple form

of the police command uses a single data rate and burst size, resulting in two outcomes: conform

and nonconform. The conforming data rate is specified in kilobits-per-second (Kbps) and is an

integer from 1 to 4294967295. The conforming burst size is specified in kilobytes (KB) and is an

integer from 1 to 128.

For each outcome, the only possible actions are drop,

set-cos-transmit,| set-sec-cos-transmit,

set-

dscp-transmit, set-prec-transmit, or transmit. In this simple form of the police command, the

conform action defaults to transmit and the violate action defaults to drop. These actions can be set

with this command once the style has been configured.

For set-dscp-transmit, a <

dscpval>

value is required and is specified as either an integer from 0 to

63, or symbolically through one of the following keywords:

af11, af12, af13, af21, af22, af23, af31, af32,

af33, af41, af42, af43, be, cs0, cs1, cs2, cs3, cs4, cs5, cs6, cs7, ef

For set-prec-transmit, an IP Precedence value is required and is specified as an integer from 0-7.

police-single-rate

This command is used to establish the traffic policing style for the specified class. The single-rate

form of the police command uses a single data rate and two burst sizes, resulting in three

outcomes: conform, exceed and violate. The conforming data rate is specified in kilobits-per-

second (Kbps) and is an integer from 1 to 4294967295. The conforming burst size is specified in

kilobytes (KB) as an integer from 1 to 128. The exceeding burst size is specified in kilobytes (KB)

as an integer from 1 to 128. Note that the exceeding burst size must be equal to or greater than the

conforming burst size.

For each outcome, the only possible actions are drop,

set-cos-transmit, set-sec-cos-transmit,

set-

dscp-transmit, set-prec-transmit, or transmit. In this singlerate form of the police command, the

conform action defaults to send, the exceed action defaults to drop, and the violate action defaults

to drop. These actions can be set with this command once the style has been configured.

For set-dscp-transmit, a <

dscpval>

value is required and is specified as either an integer from 0 to

63, or symbolically through one of the following keywords:

af11, af12, af13, af21, af22, af23, af31, af32,

af33, af41, af42, af43, be, cs0, cs1, cs2, cs3, cs4, cs5, cs6, cs7, ef

Quality of Service (QoS) Commands

202-10088-01, March 2005

police-two-rate

This command is used to establish the traffic policing style for the specified class. The two-rate

form of the police command uses two data rates and two burst sizes, resulting in three outcomes:

conform, exceed and violate. The first two data parameters are the conforming data rate and burst

size. The conforming data rate is specified in kilobits-per-second (Kbps) and is an integer from 1

to 4294967295, while the conforming burst size is specified in kilobytes (KB) as an integer from 1

to 128. The next two data parameters are the peak data rate and burst size. The peak data rate is

specified in kilobits-per-second (Kbps) as an integer from 1 to 4294967295, while the peak burst

size is specified in kilobytes (KB) as an integer from 1 to 128. Note that the peak data rate must be

equal to or greater than the conforming data rate.

For each outcome, the only possible actions are drop,

set-cos-transmit, set-sec-cos-transmit,

set-

dscp-transmit, set-prec-transmit, or transmit. In this two-rate form of the police command, the

conform action defaults to send, the exceed action defaults to drop, and the violate action defaults

to drop. These actions can be set with this command

For set-dscp-transmit, a <

dscpval>

value is required and is specified as either an integer from 0 to

63, or symbolically through one of the following keywords:

af11, af12, af13, af21, af22, af23, af31, af32,

af33, af41, af42, af43, be, cs0, cs1, cs2, cs3, cs4, cs5, cs6, cs7, ef

Quality of Service (QoS) Commands

11-27

202-10088-01, March 2005

policy-map

This command establishes a new DiffServ policy. The <

policyname>

parameter is a case-sensitive

alphanumeric string from 1 to 31 characters uniquely identifying the policy. The type of policy is

specific to either the inbound or outbound traffic direction as indicated by the {

in | out}

parameter.

Note: The policy type dictates which of the individual policy attribute commands are valid within

the policy definition.

Note: The CLI mode is changed to Policy-Map Config when this command is successfully

executed.

Format

policy-map <policyname> <in | out>

Mode

Global Config

no policy-map

This command eliminates an existing DiffServ policy. The <

policyname>

parameter is the name

of an existing DiffServ policy. This command may be issued at any time; if the policy is currently

referenced by one or more interface service attachments, this deletion attempt shall fail.

Format

no policy-map <policyname>

Mode

Global Config

policy-map rename

This command changes the name of a DiffServ policy. The <

policyname>

is the name of an

existing DiffServ class. The <

newpolicyname>

parameter is a case-sensitive alphanumeric string

from 1 to 31 characters uniquely identifying the policy.

Format

policy-map rename <policyname> <newpolicyname>

Mode

Global Config

randomdrop

This command changes the active queue depth management scheme from the default tail drop to

RED. The first two data parameters are the average queue depth minimum and maximum

threshold values specified in bytes. The minimum threshold is an integer from 1 to 250000. The

maximum threshold is an integer from 1 to 500000, but it must be equal to or greater than the

minimum threshold. The third data parameter is the maximum drop probability and is an integer

from 0 to 100. It indicates the percentage likelihood that a packet will be dropped when the

average queue depth reaches the maximum threshold value.

Quality of Service (QoS) Commands

202-10088-01, March 2005

The remaining parameters are all optional. The fourth data parameter is the sampling rate,

indicating the period at which the queue is sampled for computing the average depth. Expressed in

microseconds, the sampling rate is an integer from 0 to 1000000, with a default of 0 (meaning per-

packet sampling). The last parameter is the decay exponent, which determines how quickly the

average queue length calculation decays over time, with a higher number producing a faster rate of

decay. This value is an integer from 0 to 16, with a default of 9.

Note:

The last two parameters, namely sampling rate and decay exponent, are hierarchically

specified in this command. That is, in order to provide a value for the decay exponent <0-16>, the

user is required to also specify a sampling rate <

0-1000000>

for proper command interpretation.

Format

randomdrop <1-250000> <1-500000> <0-100> [<0-1000000>

[<0-16>]]

Mode

Policy-classmap Config

Policy Type

Out

shape average

This command is used to establish average rate traffic shaping for the specified class, which limits

transmissions for the class to the committed information rate, with excess traffic delayed via

queueing. The committed information rate is specified in kilobits-per-second (Kbps) and is an

integer from 1 to 4294967295.

Note:

Queue depth management defaults to tail drop, but the randomdrop command can be used

to change to a RED scheme.

Format

shape average <1-4294967295>

Mode

Policy-classmap Config

Restrictions

This shaping rate must not exceed the maximum link data rate of

the interface to which the policy is applied.

Policy Type

Out

shape peak

This command is used to establish peak rate traffic shaping for the specified class, which allows

transmissions for the class to exceed the committed information rate by sending excess traffic with

the understanding that it could be dropped by a downstream network element. Two rate parameters

are used, a committed information rate and a peak information rate. Each of these rates is specified

in kilobits-per-second (Kbps) and is an integer from 1 to 4294967295. The peak rate must be

specified as equal to or greater than the committed rate.
