ATM QoS Traffic Descriptor Profiles

This chapter provides information to configure QoS traffic descriptor profiles using the command line interface.

Topics in this chapter include:

ATM Traffic Descriptor Profiles

This section provides a description of support for ATM QoS policy features. Each traffic descriptor defines the expected rates and characteristics of traffic.

ATM Traffic Management

The 7705 SAR supports the ATM Forum Traffic Management Specification Version 4.1.

This section contains the following topics related to the QoS features for ATM Permanent Virtual Connections (PVCs):

ATM Service Categories

The 7705 SAR supports the following service categories:

CBR – Constant Bit Rate
rt-VBR – Real-Time Variable Bit Rate
nrt-VBR –Non-Real-Time Variable Bit Rate
UBR/UBR+MIR – Unspecified Bit Rate with Minimum Cell Rate (UBR is a special case of UBR+MIR where MIR=0)

ATM Traffic Descriptors and QoS Parameters

ATM Traffic Descriptors shows the ATM traffic descriptors supported on the 7705 SAR.

Table 1. ATM Traffic Descriptors
Service Category	Traffic Descriptors
CBR	P0_1
CBR	PIR in kb/s (applies to CLP=0 and CLP=1 flows)
rt-VBR and nrt-VBR	P0_1 and S0_1
	PIR in kb/s (applies to CLP=0 and CLP=1 flows)
	SIR in kb/s (applies to CLP=0 and CLP=1 flows)
	MBS in cells (applies to CLP=0 and CLP=1 flows)
	P0_1 and S0
	PIR in kb/s (applies to CLP=0 and CLP=1 flows; non-conforming CLP=0 cells are discarded)
	SIR in kb/s (applies to CLP=0 flow only)
	MBS in cells (applies to CLP=0 flow only)
	P0_1 and S0_Tag
	PIR in kb/s (applies to CLP=0 and CLP=1 flows; non-conforming CLP=0 flows are tagged to CLP=1 flows)
UBR/UBR+MIR	P0_1
	PIR in kb/s (applies to CLP=0 and CLP=1 flows)
	MIR in kb/s (applies to CLP=0 and CLP=1 flows)

ATM Policing

The policing option, when enabled, applies only to ingress traffic. Similarly, the shaping option, if enabled, applies only to egress traffic. For example, if a traffic descriptor has both policing and shaping enabled, the policing option is enforced for the ingress traffic, while the shaping option is enforced for the egress traffic. The following ATM service category conformance definitions are supported:

P0_1 – CBR
P0_1 and S0_1 – VBR.1
P0_1 and S0 – VBR.2
P0_1 and S0_Tag – VBR.3

P represents the peak rate, S represents the sustained rate, 0 or 1 represents the CLP value to which policing is applied if the cell is non-conforming, and Tag indicates that the CLP value has changed from 0 to 1. For example:

P0_1 — means that policing is applied to non-conforming peak rate cells with CLP values of 0 or 1
P0_1 and S0_Tag — means that policing is applied to non-conforming peak rate cells with CLP values of 0 or 1 and policing is applied to non-conforming sustained rate cells with a CLP value of 0 with the action to change the CLP value to 1

Shaping

ATM layer egress shaping is supported for CBR, rt-VBR, and nrt-VBR VCs. A CBR VC is shaped to a single leaky bucket with the parameter PIR from the traffic descriptor. An rt-VBR VC or an nrt-VBR VC is shaped to two leaky buckets with parameters PIR and SIR, BT from the traffic descriptor, where BT is the Burst Tolerance and is a function of the MBS parameters configured by the user. The traffic rates and shaping parameter that are configured in the sap-egress QoS policy are not used at ATM SAPs.

In order to enforce the Service Level Agreement, ATM layer ingress policing is supported at ingress, so no shaping is needed. At ingress, after optional policing is applied, packet level queue-based soft-policing is supported per the service ingress QoS policy applied to the ATM SAP.

Note: Shaping to the specified traffic descriptor in the ATM traffic descriptor profile is always enabled for CBR and rt-VBR VCs.

ATM Queuing and Scheduling

The 7705 SAR provides a per-VC queuing architecture on the 16-port T1/E1 ASAP Adapter card, 32-port T1/E1 ASAP Adapter card, and 2-port OC3/STM1 Channelized Adapter card with atm/ima encapsulation. The 7705 SAR provides a per-VC queuing architecture on the 4-port OC3/STM1 Clear Channel Adapter card and 4-port DS3/E3 Adapter card with atm encapsulation. In the egress direction toward the ATM port, the scheduling priority at the ATM layer is as follows.

CBR VCs are always shaped and are scheduled with strict priority over all other service categories.
rt-VBR VCs are always shaped and are scheduled next with strict priority over nrt-VBR and UBR VCs.
nrt-VBR shaped VCs are scheduled next with strict priority over nrt-VBR unshaped VCs and UBR VCs.
nrt-VBR unshaped VCs and UBR VCs are scheduled as a common class. Scheduling among these VCs is done using a Weighted Round Robin (WRR) scheduler, where the weight of each VC is determined by the configured SIR for nrt-VBR and by the MIR for UBR VCs. The scheduling is work-conserving, so each VC has access to excess bandwidth in proportion to its SIR/MIR. Under congestion, the performance of each VC degrades proportionally to the weight of the VC.

Congestion Avoidance

Congestion and potential discards are performed on a per-forwarding class basis in the SAP queues in the CSM.

Basic Configuration

This section contains the following topics related to creating and applying ATM QoS policies:

A basic ATM QoS traffic descriptor profile must conform to the following rules.

Each policy must have a unique policy ID.
Default values can be modified but parameters cannot be deleted.

Creating an ATM Traffic Descriptor Profile QoS Policy

Configuring and applying QoS policies and profiles other than the default policy is optional. To create an ATM QoS traffic descriptor profile, perform the following:

assign a policy ID (policy number) — the system does not dynamically assign an ID
include a description — provides a brief overview of policy features
configure traffic attributes of the ATM traffic profile
determine whether egress shaping should occur

Use the following CLI syntax to configure an atm-td-profile policy.

CLI Syntax:

config>qos#
    atm-td-profile traffic-desc-profile-id
        description description-string
        descriptor-type {P0_1|P0_1andS0_Tag|P0_1andS0|P0_1andS0_1}
        [no] policing 
        service-category service-category
        [no] shaping
        traffic [sir sir-val] [pir pir-val] [mir mir-val] [mbs mbs-val][cdvt cdvt-val]

The following output displays an example of the command syntax.

Example:

*A:ALU-1# config qos
config>qos# atm-td-profile 3 create
config>qos>atm-td-profile$ description "ATM TD profile3"
config>qos>atm-td-profile$ service-category rt-vbr
config>qos>atm-td-profile$ descriptor-type P0_1andS0_1
config>qos>atm-td-profile$ policing
config>qos>atm-td-profile$ shaping
config>qos>atm-td-profile$ traffic sir 500 pir 500 mbs 500 cdvt 500
config>qos>atm-td-profile$ exit
config>qos# exit

The following output displays the profile configuration for ATM TD profile 3:

*A:ALU-1>config>qos# info
#--------------------------------------------------
echo "QoS Policy Configuration"
#--------------------------------------------------

            traffic sir 500 pir 500 mbs 500 cdvt 500
            policing
        exit
...
*A:ALU-1

Applying ATM Traffic Descriptor Profile Policies

ATM QoS traffic descriptor profiles are applied to ATM VLL (Apipe) SAPs. ATM QoS traffic descriptor profiles can also be applied on egress to ATM VCC SAPs that are members of a SAP aggregation group. You cannot apply ATM QoS traffic descriptor profiles on ingress to a SAP in a SAP aggregation group; the profile is set to the default (1).

ATM VLL (Apipe) SAPs

Use the following CLI syntax to apply ATM QoS traffic descriptor profile policies to Apipe SAPs on ingress and egress.

CLI Syntax:

config>service>apipe>sap# atm
    egress
        traffic-desc traffic-desc-profile-id
    ingress
        traffic-desc traffic-desc-profile-id

Default ATM Traffic Descriptor Profile Policy Values

The default ATM QoS traffic descriptor profile is 1. The default profile cannot be edited or deleted.

ATM-TD-Profile Defaults below shows the ATM TD profile defaults.

Table 2. ATM-TD-Profile Defaults
Field	Default

Service Management Tasks

This section describes the following ATM Traffic Descriptor Profile service management tasks:

Removing an ATM Traffic Descriptor Profile from the QoS Configuration

The default ATM traffic descriptor profile cannot be deleted.

To delete an ATM QoS traffic descriptor profile, enter the following command:

CLI Syntax:

config>qos# no atm-td-profile traffic-desc-profile-id

Example:

config>qos# no atm-td-profile 3

Copying and Overwriting an ATM Traffic Descriptor Profile

You can copy an existing profile, rename it with a new profile ID value, or overwrite an existing profile ID. The overwrite option must be specified or an error occurs if the destination profile ID exists.

CLI Syntax:

config>qos# copy atm-td-profile src-prof dst-prof [overwrite]

Example:

*A:ALU-1#>config>qos# copy atm-td-profile 2 3
A:ALU-48>config>qos# copy atm-td-profile 2 3 overwrite
A:ALU-48>config>qos#

Editing QoS Policies

You can change existing policies and entries in the CLI. The changes are applied immediately to all services where this policy is applied. To prevent configuration errors, copy the policy to a work area, make the edits, and then write over the original policy.

Command Descriptions

Configuration Commands

Generic Commands

description

Syntax

description description-string

no description

Context

config>qos>atm-td-profile

Description

This command creates a text description stored in the configuration file for a configuration context.

The no form of this command removes any description string from the context.

Default

n/a

Parameters

description-string: a text string describing the entity. Allowed values are any string up to 80 characters long composed of printable, 7-bit ASCII characters excluding double quotes. If the string contains special characters (such as #, $, or spaces), the entire string must be enclosed within double quotes.

ATM QoS Policy Commands

atm-td-profile

Syntax

[no] atm-td-profile traffic-desc-profile-id [create]

Context

config>qos

Description

This command is used to configure an ATM traffic descriptor profile as per ATM Forum Traffic Management Specification Version 4.1.

Traffic descriptor profiles are used to:

define traffic management capabilities for ATM PVCCs
calculate the total bandwidth consumed on a given port by all ATM PVCCs. The bandwidth taken by a PVCC is equal to:
PIR for CBR PVCCs
SIR for rt-vbr and nrt-vbr PVCCs
MIR for UBR PVCC
define ATM-level scheduling

The default traffic descriptor is preconfigured and non-modifiable. It cannot be deleted. All other traffic descriptor profiles must be explicitly created before use. The create keyword must follow each new profile configuration.

Any changes made to the existing profile, using any of the sub-commands, are applied immediately to all objects where this profile is applied (a small traffic interruption in data traffic will occur during the data plane reprogramming with the newly modified profile).

When many changes are required on a profile, it is recommended that the profile be copied to a work area profile ID. That work-in-progress profile can be modified until complete and then written over the original profile-id. Use the config>qos>copy command to maintain profiles in this manner.

The weight assigned to each non-shaped PVCC in the Deficit Round Robin Scheduler depends on the service category and traffic rates (see the traffic command for more details).

The no form of the command deletes a given traffic profile. The profile to be deleted must not be associated with any object (for example a SAP). If this condition is not met, the command will return an error.

Default

1 — the default traffic descriptor (UBR, no traffic, no shaping)

Parameters

traffic-desc-profile-id

the index identifier for a traffic descriptor profile

Values: 1 to 1000

create: keyword used to create an ATM traffic descriptor profile

descriptor-type

Syntax

descriptor-type type

Context

config>qos>atm-td-profile

Description

This command is used to specify the type of ATM traffic descriptor profile as per ATM Forum Traffic Management Specification Version 4.1.

Service Category Descriptor Type Default Values defines the descriptor-type default values based on service category, and Traffic Descriptor Type Parameters defines how the traffic parameters that are specified for the descriptor profiles are interpreted.

Note: Setting descriptor-type to a value that is not compatible with the service category as defined in the table results in an error message.

Table 3. Service Category Descriptor Type Default Values
Service Category	Default Descriptor Type
CBR	P0_1
UBR	P0_1
UBR with MIR	P0_1
rt-VBR or nrt-VBR	P0_1and S0_1

Table 4. Traffic Descriptor Type Parameters
Descriptor-type Value	Rates Interpretation	Applicable Service Categories
P0_1	PIR in kb/s; applies to CLP=0 and CLP=1 cell flows MIR in kb/s; applies to CLP=0 and CLP=1 cell flows	CBR, UBR, UBR with MIR
P0_1andS0	PIR in kb/s; applies to CLP=0 and CLP=1 cell flows; non-conforming CLP=0 cell flows are discarded SIR in kb/s; applies to CLP=0 cell flows only	rt-VBR and nrt-VBR
P0_1andS0_Tag	PIR in kb/s; applies to CLP=0 and CLP=1 cell flows; non-conforming CLP=0 cell flows are tagged to CLP=1 cell flows SIR in kb/s; applies to CLP=0 cell flows only	rt-VBR and nrt-VBR
P0_1andS0_1	PIR in kb/s; applies to CLP=0 and CLP=1 cell flows SIR in kb/s; applies to CLP=0 cell flows only	rt-VBR and nrt-VBR

Default

see Service Category Descriptor Type Default Values

Parameters

type

the ATM traffic descriptor profile type

Values: P0_1, P0_1andS0_Tag, P0_1andS0, P0_1andS0_1

policing

Syntax

[no] policing

Context

config>qos>atm-td-profile

Description

This command determines whether ingress traffic is policed. Policing is valid for CBR, rt-VBR, nrt-VBR, and UBR. This policing is cell-based.

Default

disabled

service-category

Syntax

service-category service-category

Context

config>qos>atm-td-profile

Description

This command is used to configure an ATM service category attribute of an ATM traffic descriptor profile.

Default

ubr

Parameters

service-category

ATM Service Categories describes the supported ATM service categories on the 16-port T1/E1 ASAP Adapter card, 32-port T1/E1 ASAP Adapter card, 4-port DS3/E3 Adapter card, 4-port OC3/STM1 Clear Channel Adapter card, and 2-port OC3/STM1 Channelized Adapter card.

Table 5. ATM Service Categories
Service Category	Description
CBR	Constant Bit Rate
rt-VBR	Real-time Variable Bit Rate
nrt-VBR	Non-real-time Variable Bit Rate
UBR	Unspecified Bit Rate without Minimum Desired Cell Rate (defined by specifying service category to be ubr, and MIR of 0)
UBR (with MIR)	Unspecified Bit Rate with non-zero Minimum Desired Cell Rate (defined by specifying service category to be ubr, and MIR > 0)

Changing the service category of a profile will reset all traffic attributes to their defaults (see the traffic command) and will cause reprogramming of the data path (with a small impact on user traffic) and a reset of VC statistics for all VCs using this traffic descriptor profile.

shaping

Syntax

[no] shaping

Context

config>qos>atm-td-profile

Description

This command determines whether egress shaping should occur. Shaping is only applied in the egress direction.

Default

The default is determined by the service category. Default Shaping Values describes default shaping values.

Table 6. Default Shaping Values
Applicable Service Category	Default Shaping Value	Comments
UBR	Disabled	Shaping cannot be enabled
CBR	Enabled	Shaping cannot be disabled
rt-VBR	Enabled	Shaping cannot be disabled
nrt-VBR	Enabled	Shaping cannot be disabled

traffic

Syntax

traffic [sir sir-val [pir pir-val] [mir mir-val] [mbs mbs-val] [cdvt cdvt-val]

no traffic

Context

config>qos>atm-td-profile

Description

This command is used to configure traffic attributes of an ATM traffic profile as per ATM Forum Traffic Management Specification Version 4.1.

The traffic parameters of a traffic descriptor that are configurable depend on the service category of this traffic descriptor profile. (See the service-category command.)

Service Category Traffic Descriptor Parameters defines which traffic descriptor parameters are applicable for what service category and what the configuration rules are between the parameters. ‟Y” indicates that the parameter can be configured for a given service category and will be defaulted if not provided, and an ‟N/A” indicates that the parameter cannot be configured for a given service category (an error will be returned). If an applicable parameter is not specified, the current value will be preserved.

Table 7. Service Category Traffic Descriptor Parameters
Service Category	SIR	PIR	MBS	MIR	CDVT
CBR	N/A	Y	N/A	N/A	Y
rt-VBR	Y	Y (must be ≥ SIR)	Y	N/A	Y
nrt-VBR	Y	Y (must be ≥ SIR)	Y	N/A	Y
UBR	N/A	Y	N/A	N/A	Y
UBR with MIR	N/A	Y (must be ≥ MIR	N/A	Y (non-zero MIR specified)	Y

When a traffic descriptor profile is used to define egress scheduling, the following describes how traffic rates are used to derive scheduling weight:

The scheduling weight applies only to unshaped nrt-VBR and UBR. The scheduling weight is a value from 1 to 8. The scheduling weight is determined by the SIR value for nrt-VBR, and by the MIR value for UBR. The conversion from SIR/MIR to weight is as follows:

Rate < 64K weight = 1
Rate < 128K weight = 2
Rate < 256K weight = 3
Rate < 512K weight = 4
Rate < 1024K weight = 5
Rate < 1536K weight = 6
Rate < 1920K weight = 7

Everything above 1920K will be assigned a weight of 8.

Since the 7705 SAR operates in cells/second with one cell granularity, PIR and SIR values programmed need to be converted to cells/second. When converting values to be used for the scheduler, the result is rounded up to the next cell when required by conversion.

When any of SIR, PIR, or MIR is greater than the physical maximum port/channel capacity for a given PVCC, then the maximum physical port/channel capacity is used in bandwidth accumulation and when configuring the hardware for that PVCC.

Hardware-enforceable MBS is in the inclusive range of 3 to 256 000 cells on all 7705 SAR ATM-capable adapter cards. Assigning an atm-td-profile with an MBS value outside of this range to a SAP is blocked. As well, once an atm-td-profile is assigned to a SAP, the CLI will block any change of the MBS value to a value outside of this range.

The no form of the command restores traffic parameters to their defaults for a given service category.

Default

ATM Traffic Parameter Defaults shows the ATM traffic parameter defaults.

Operational Commands

copy

Syntax

copy atm-td-profile src-prof dst-prof [overwrite]

Context

config>qos

Description

This command copies the source ATM traffic descriptor profile into the destination ATM profile. If the destination profile was already defined, the keyword overwrite must be appended for the copy to complete.

The copy command is a configuration level maintenance tool used to create new profiles using existing profiles. It also allows bulk modifications to an existing profile with the use of the overwrite keyword.

Parameters

src-prof dst-prof

indicates that the source profile ID and the destination profile ID are atm-td-profile IDs. Specify the source ID that the copy command will copy and specify the destination ID to which the command will duplicate the profile.

Values: 1 to 1000

overwrite

specifies that the existing destination profile is to be replaced. Everything in the existing destination profile will be overwritten with the contents of the source profile. If overwrite is not specified, an error will occur if the destination profile ID exists.

ALU-48>config>qos# copy atm-td-profile 2 10

MINOR: CLI destination (10) exists use {overwrite}.

ALU-48>config>qos# copy atm-td-profile 2 10 overwrite
