map-class frame-relay

To specify a map class to define quality of service (QoS) values for a switched virtual circuit (SVC), use the map-class frame-relay global configuration command.

map-class frame-relay map-class-name

Syntax Description

map-class-name

Name of this map class.


Defaults

Disabled

Command Modes

Global configuration

Command History

Release
Modification

11.2

This command was introduced.


Usage Guidelines

After you specify the named map class, you can specify the QoS parameters—such as incoming and outgoing committed information rate (CIR), committed burst rate, excess burst rate, and the idle timer—for the map class.

To specify the protocol-and-address combination to which the QoS parameters are to be applied, associate this map class with the static maps under a map list.

Examples

The following example specifies a map class called "hawaii" and defines three QoS parameters for it. The "hawaii" map class is associated with a protocol-and-address static map defined under the map-list command.

map-list bermuda source-addr E164 123456 dest-addr E164 654321
 ip 10.108.177.100 class hawaii
 appletalk 1000.2 class hawaii

map-class frame-relay hawaii 
 frame-relay cir in 2000000
 frame-relay cir out 56000
 frame-relay be out 9000

11.2

This command was introduced.


Usage Guidelines

A map-group association with an interface is required for switched virtual circuit (SVC) operation. In addition, a map list must be configured.

The map-group command applies to the interface or subinterface on which it is configured. The associated E.164 or X.121 address is defined by the map-list command, and the associated protocol addresses are defined by using the class command under the map-list command.

Examples

The following example configures a physical interface, applies a map group to the physical interface, and then defines the map group:

interface serial 0
 ip address 172.10.8.6
 encapsulation frame-relay
 map-group bermuda
 frame-relay lmi-type q933a
 frame-relay svc

map-list bermuda source-addr E164 123456 dest-addr E164 654321

Usage Guidelines

Use the map-class command and its subcommands to define quality of service (QoS) parameters—such as incoming and outgoing committed information rate (CIR), committed burst rate, excess burst rate, and the idle timer—for the static maps defined under a map list.

Each SVC needs to use a source and destination number, in much the same way that a public telephone network needs to use source and destination numbers. These numbers allow the network to route calls from a specific source to a specific destination. This specification is done through map lists.

Depending on switch configuration, addressing can take either of two forms: E.164 or X.121.

An X.121 address number is 14 digits long and has the following form:

Z CC P NNNNNNNNNN

Table 35 describes the codes in an X.121 address number form.

An E.164 number has a variable length; the maximum length is 15 digits. An E.164 number has the fields shown in Figure 1 and described in Table 36.

Figure 1 E.164 Address Format 

Table 36 E.164 Address Field Descriptions

Field
Description

Country code

Can be 1, 2, or 3 digits long. Some current values are the following:

Code 1—United States of America

Code 44—United Kingdom

Code 61—Australia

National destination code + subscriber number

Referred to as the National ISDN number; the maximum length is 12, 13, or 14 digits, based on the country code.

ISDN subaddress

Identifies one of many devices at the termination point. An ISDN subaddress is similar to an extension on a PBX.


Examples

In the following SVC example, if IP or AppleTalk triggers the call, the SVC is set up with the QoS parameters defined within the class "hawaii". An SVC triggered by either protocol results in two SVC maps, one for IP and one for AppleTalk. Two maps are set up because these protocol-and-address combinations are heading for the same destination, as defined by the dest-addr keyword and the values following it in the map-list command.

map-list bermuda source-addr E164 123456 dest-addr E164 654321
 ip 131.108.177.100 class hawaii
 appletalk 1000.2 class hawaii

map-class frame-relay

Specifies a map class to define QoS values for an SVC.


match

To specify whether to use the first three bits in the type of service (ToS) octet or the first six bits of the Differentiated Services Code Point (DSCP) octet of the IP header for mapping packet service levels to Frame Relay permanent virtual circuit (PVC) bundle members, use the match command in Frame Relay VC-bundle configuration mode. To change the mapping scheme used, override the current configuration by using the match command with the other keyword. The no form of this command has no effect.

match {dscp | precedence}

Syntax Description

dscp

Specifies that the DSCP octet in the IPv4 header is used to map packet service levels to specific Frame Relay PVC bundle members. Currently the first six bits of the DSCP octet are used for mapping, providing 64 packet service levels numbered 0 through 63.

precedence

Specifies that the precedence field of the ToS octet is used to map packet service levels to specific Frame Relay PVC bundle members. The precedence field consists of the first three bits of the ToS octet, providing eight precedence levels numbered 0 through 7.


Defaults

precedence

Modification

12.2(13)T

This command was introduced.


Usage Guidelines

The default PVC bundle match type is precedence. To change the match type to DSCP, use the match dscp command. When this command is executed, the system displays the message "Resetting vc-bundle configuration" on the console. When the match type is changed, the system removes all level designations that were previously configured.

To return the PVC bundle match type to the default setting of precedence, use the match precedence command.

A PVC bundle cannot perform precedence matching and DSCP matching at the same time. If the wrong matching scheme is configured for the traffic type, unpredictable behavior will result.

When tag-switching is enabled on the interface by using the tag-switching ip command, PVC bundles that are configured for IP precedence mapping are automatically converted to MPLS EXP mapping. The PVC bundle functionality remains the same with respect to priority levels, bumping, and so on, but the match precedence command is replaced by "match exp", and each precedence command is replaced by the exp command. The result is that a bundle-member PVC previously configured to carry precedence level 1 IP traffic now carries EXP level 1 MPLS traffic.

PVC bundles configured for DSCP mapping go down when tag-switching is enabled. The DSCP configuration for each bundle-member PVC is reset, causing the PVCs to be unmapped and Inverse ARP, bumping, and protection settings to be unconfigured. The match dscp command is replaced by "match exp".

When tag-switching is disabled, the match precedence and match dscp commands are restored.

Examples

The following example sets the match type to DSCP for the PVC bundle MP-4-dynamic:

Router(config)# interface serial 1/4.1 multipoint
Router(config-if)# frame-relay vc-bundle MP-4-dynamic
Router(config-fr-vcb)# match dscp
%Resetting vc-bundle configuration.

Command
Description

dscp (Frame Relay VC-bundle-member)

Configures the DSCP value or values for a Frame Relay PVC bundle member.

exp

Configures MPLS EXP levels for a Frame Relay PVC bundle member.

precedence (Frame Relay VC-bundle-member)

Configures the precedence levels for a Frame Relay PVC bundle member.


precedence (Frame Relay VC-bundle-member)

To configure the precedence levels for a Frame Relay permanent virtual circuit (PVC) bundle member, use the precedence command in Frame Relay VC-bundle-member configuration mode. To remove the precedence level configuration from the PVC, use the no form of this command.

precedence {level | other}

no precedence

Syntax Description

level

Specifies the precedence level or levels for this Frame Relay PVC bundle member. The range is from 0 to 7. A PVC bundle member can be configured with a single precedence level, multiple individual precedence levels, a range of precedence levels, multiple ranges of precedence levels, or a combination of individual levels and level ranges. Examples are as follows:

0

0,2,3

0-2,4-5

0,1,2-4,7

other

Specifies that this Frame Relay PVC bundle member will handle all of the remaining precedence levels that are not explicitly configured on any other bundle member PVCs.


Defaults

Precedence levels are not configured.

Command Modes

Command History

Release
Modification

12.2(13)T

This command was introduced.


Usage Guidelines

Assignment of precedence levels to PVC bundle members allows you to create differentiated service because you can distribute the IP precedence levels over the various PVC bundle members. You can map a single precedence level or a range of levels to each discrete PVC in the bundle, thereby enabling PVCs in the bundle to carry packets marked with different precedence levels. Use the precedence other command to indicate that a PVC can carry traffic marked with precedence levels not specifically configured for other PVCs. Only one PVC in the bundle can be configured using the precedence other command.

This command is available only when the match type for the PVC bundle is set to precedence using the match precedence command in Frame Relay VC-bundle configuration mode.

You can overwrite the precedence level configuration on a PVC by reentering the precedence command with a new level value.

All precedence levels must be accounted for in the PVC bundle configuration, or the bundle will not come up. Note, however, that a PVC may be a bundle member but have no precedence level associated with it. As long as all valid precedence levels are handled by other PVCs in the bundle, the bundle can come up, but the PVC that has no precedence level configured will not participate in it.

A precedence level can be configured on one PVC bundle member per bundle. If you configure the same precedence level on more than one PVC within a bundle, the following error warning appears on the console:

%Overlapping precedence levels

When tag-switching is enabled on the interface by using the tag-switching ip command, MPLS and IP packets can flow across the interface, and PVC bundles that are configured for IP precedence mapping are converted to MPLS EXP mapping. The PVC bundle functionality remains the same with respect to priority levels, bumping, and so on, but the match precedence command is replaced by "match exp", and each precedence command is replaced by the exp command. The result is that a bundle-member PVC previously configured to carry precedence level 1 IP traffic now carries EXP level 1 MPLS traffic.

When tag-switching is disabled, the match precedence and match dscp commands are restored, and the exp commands are replaced by precedence commands.

When tag-switching is enabled or disabled, PVC bundles configured for IP precedence mapping or MPLS EXP mapping will stay up, and traffic will be transmitted over the appropriate bundle-member PVCs.

Examples

The following example configures Frame Relay PVC bundle member 101 to carry traffic with IP precedence level 5:

frame-relay vc-bundle new-york
 match precedence
 pvc 101
  precedence 5

protect (Frame Relay VC-bundle-member)

To configure a Frame Relay protected permanent virtual circuit (PVC) bundle member with protected group or protected PVC status, use the protect command in Frame Relay VC-bundle-member configuration mode. To remove the protected status from the PVC, use the no form of this command.

protect {group | vc}

no protect {group | vc}

Syntax Description

group

Configures the PVC bundle member as part of a collection of protected PVCs within the PVC bundle.

vc

Configures the PVC member as individually protected.


Defaults

The PVC neither belongs to the protected group nor is an individually protected PVC.

Command Modes

Command History

Release
Modification

12.2(13)T

This command was introduced.


Usage Guidelines

When an individually protected PVC goes down, it takes the bundle down. When all members of a protected group go down, the bundle goes down.

Despite any protection configurations, the PVC bundle will go down if a downed PVC has no PVC to which to bump its traffic or if the last PVC that is up in a PVC bundle goes down.

Examples

The following example configures Frame Relay PVC bundle member 101 as an individually protected PVC:

frame-relay vc-bundle new york
 pvc 101
  protect vc

Usage Guidelines

To use this command, you must first create a Frame Relay PVC bundle and enter Frame Relay VC-bundle configuration mode.

A PVC bundle must have at least one PVC for the bundle to come up. A PVC bundle cannot have more than eight PVCs. If you try to configure more than eight PVCs in a bundle, the following message will appear on the console:

%FR vc-bundle contains 8 members. Cannot add another.

Dynamic PVCs can be specified as PVC bundle members; however, if a PVC has already been created by using some other configuration command, you will not be able to add it to a PVC bundle. If you try to add it to a bundle, the following message will appear on the console:

%DLCI 200 is not a dynamic PVC. Cannot add to VC-Bundle.

If a PVC is already a member of a PVC bundle, any attempt to reuse that same PVC in a command that creates a PVC (e.g. frame-relay interface-dlci, frame-relay local-dlci) will result in the following error message:

%Command is inapplicable to vc-bundle PVCs.

Examples

The following example creates PVC 101 belonging to the Frame Relay PVC bundle named "new_york":

frame-relay vc-bundle new_york

no shape fr-voice-adapt

Syntax Description

deactivation seconds

(Optional) Number of seconds that must elapse after the last voice packet is transmitted before the sending rate is increased to the committed information rate (CIR). The range is from 1 to 10000.


Defaults

Frame Relay voice-adaptive traffic shaping is not enabled.
Seconds: 30

Command Modes

Command History

Release
Modification

12.2(15)T

This command was introduced.


Usage Guidelines

Frame Relay voice-adaptive traffic shaping enables a router to reduce the permanent virtual circuit (PVC) sending rate to the minimum CIR (minCIR) whenever packets (usually voice) are detected in the low latency queueing priority queue or H.323 call setup signaling packets are present. When there are no packets in priority queue and signaling packets are not present for a configured period of time, the router increases the PVC sending rate from minCIR to CIR to maximize throughput.

The shape fr-voice-adapt command can be configured only in the class-default class. If you configure the shape fr-voice-adapt command in another class, the associated Frame Relay map class will be rejected when you attach it to the interface.

Frame Relay voice-adaptive traffic shaping can be used with other types of adaptive traffic shaping. For example, when both voice-adaptive traffic shaping and adaptive shaping based on interface congestion are configured, the sending rate will change to minCIR if there are packets in the priority queue or the interface queue size exceeds the configured threshold.


Note Although the priority queue is generally used for voice traffic, Frame Relay voice-adaptive traffic shaping will respond to any packets (voice or data) in the priority queue.


In order to use Frame Relay voice-adaptive traffic shaping, you must have low latency queueing and traffic shaping configured using the Modular QoS CLI.

Examples

The following example shows the configuration of Frame Relay voice-adaptive traffic shaping and fragmentation. With this configuration, priority- queue packets or H.323 call setup signaling packets destined for PVC 100 will result in the reduction of the sending rate from CIR to minCIR and the activation of FRF.12 end-to-end fragmentation. If signaling packets and priority-queue packets are not detected for 50 seconds, the sending rate will increase to CIR and fragmentation will be turned off.

Number of fragments received by this DLCI that are dropped for reasons such as running out of memory, receiving segments out of sequence, receiving an unexpected frame with a B bit set, or timing out on a reassembling frame.

out dropped fragmenting pkts

Number of fragments that are dropped by this DLCI during transmission because of running out of memory.

in timeouts

Number of reassembly timeouts that have occurred on incoming frames to this DLCI. (A frame that does not fully reassemble within two minutes is dropped, and the timeout counter is incremented.)

in out-of-sequence fragments

Number of fragments received by this DLCI that have an unexpected sequence number.

in fragments with unexpected B bit set

Number of fragments received by this DLCI that have an unexpected B bit set. When this occurs, all fragments being reassembled are dropped and a new frame is begun with this fragment.

out interleaved packets

Number of packets leaving this DLCI that have been interleaved between segments.

Modification

10.0

This command was introduced.

12.0(1)T

This command was modified to display statistics about virtual access interfaces used for PPP connections over Frame Relay.

12.0(3)XG

This command was modified to include the fragmentation type and size associated with a particular PVC when fragmentation is enabled on the PVC.

12.0(4)T

This command was modified to include the fragmentation type and size associated with a particular PVC when fragmentation is enabled on the PVC.

12.0(5)T

This command was modified to include information on the special voice queue that is created using the queue keyword of the frame-relay voice bandwidth command.

This command was modified to display the following information:

Details about the policy map attached to a specific PVC.

The priority configured for PVCs within Frame Relay PVC interface priority queueing.

Details about Frame Relay traffic shaping and policing on switched PVCs.

12.0(12)S

This command was modified to display reasons for packet drops and complete status information for switched NNI PVCs.

12.1(5)T

This command was modified to display the following information:

The number of packets in the post-hardware-compression queue.

The reasons for packet drops and complete status information for switched network-to-network PVCs.

12.2(4)T

12.2(13)T

This command was modified to support display of Frame Relay PVC bundle information.

12.2(15)T

This command was modified to support display of Frame Relay voice-adaptive fragmentation information.


Usage Guidelines

Use this command to monitor the PPP link control protocol (LCP) state as being open with an up state or closed with a down state.

When "vofr" or "vofr cisco" has been configured on the PVC, and a voice bandwidth has been allocated to the class associated with this PVC, configured voice bandwidth and used voice bandwidth are also displayed.

Statistics Reporting

To obtain statistics about PVCs on all Frame Relay interfaces, use this command with no arguments.

To obtain statistics about a PVC that include policy-map configuration or the priority configured for that PVC, use this command with the dlci argument.

Per-VC counters are not incremented at all when either autonomous or silicon switching engine (SSE) switching is configured; therefore, PVC values will be inaccurate if either switching method is used.

You can change the period of time over which a set of data is used for computing load statistics. If you decrease the load interval, the average statistics are computed over a shorter period of time and are more responsive to bursts of traffic. To change the length of time for which a set of data is used to compute load statistics for a PVC, use the load-interval command in Frame-Relay DLCI configuration mode.

Traffic Shaping

Congestion control mechanisms are currently not supported on terminated PVCs nor on PVCs over ISDN. Where congestion control mechanisms are supported, the switch passes forward explicit congestion notification (FECN) bits, backward explicit congestion notification (BECN) bits, and discard eligible (DE) bits unchanged from entry points to exit points in the network.

Examples

The various displays in this section show sample output for a variety of PVCs. Some of the PVCs carry data only; some carry a combination of voice and data.

Frame Relay Voice-Adaptive Fragmentation Example

The following sample output indicates that Frame Relay voice-adaptive fragmentation is active on DLCI 202 and there are 29 seconds left on the deactivation timer. If no voice packets are detected in the next 29 seconds, Frame Relay voice-adaptive fragmentation will become inactive.

Usage Guidelines

Use this command to display packet service levels, bumping attributes, and other information about a specific Frame Relay PVC bundle. To view packet counts for each PVC in the bundle in addition to the other attributes, use the detail keyword.

Examples

General Example

The following example shows the Frame Relay PVC bundle named "MP-4-dynamic" with PVC protection applied. Note that in this PVC bundle, data-link connection identifier (DLCI) 400 is configured to explicitly bump traffic to the PVC that handles DSCP level 40, which is DLCI 404. All the other DLCIs are configured for implicit bumping. In addition, all the DLCIs are configured to accept bumped traffic.

The asterisk (*) before PVC 4a indicates that this PVC was configured with the precedence other command, which means the PVC will handle all levels that are not explicitly configured on other PVCs.

In this example all PVCs are up so, the values in the "Active leve"l fields match the values in the "Config level" fields. If a PVC goes down and its traffic is bumped, the "Active level" field value for the PVC that went down is cleared. The "Active level" field values for the PVC that the traffic bumped to will be updated to include the levels of the PVC that went down.

The first three PVCs in the following example make up a protected group. All three of these PVCs must go down before the bundle will go down. The last two PVCs are protected PVCs: if either of these PVCs goes down, the bundle will go down.

Bumping Example

The following example shows that although some DLCIs are down, the bumping rules and the remaining DLCIs keep the bundle up and running for all traffic types.

Note that DLCI 304 is handling the traffic being bumped from the three DLCIs that are down. The "Active level" field indicates the levels that the PVC is actually handling, not just which levels are configured.

Threshold at which DE-marked packets will be discarded, specified as a percentage of maximum queue size.


Defaults

100%

Command Modes

Frame Relay congestion management configuration

Command History

Release
Modification

12.1(2)T

This command was introduced.


Usage Guidelines

You must enable Frame Relay congestion management on the interface before congestion management parameters will be effective. To enable Frame Relay congestion management and to enter Frame Relay congestion management configuration mode, use the frame-relay congestion-management interface command.

You must enable Frame Relay switching, using the frame-relay switching global command, before the threshold de command will be effective on switched PVCs.

Examples

The following example shows how to configure a DE threshold of 40% on serial interface 1.

interface serial1
 encapsulation frame-relay
 frame-relay congestion-management
  threshold de 40

Command
Description

frame-relay congestion-management

Enables Frame Relay congestion management functions on all switched PVCs on an interface, and enters congestion management configuration mode.

frame-relay congestion threshold de

Configures the threshold at which DE-marked packets will be discarded from the traffic-shaping queue of a switched PVC.

frame-relay congestion threshold ecn

Configures the threshold at which ECN bits will be set on packets in the traffic-shaping queue of a switched PVC.

frame-relay switching

Enables PVC switching on a Frame Relay DCE or NNI.

threshold ecn

Configures the threshold at which ECN bits will be set on packets in switched PVCs on the output interface.


threshold ecn

To configure the threshold at which ECN bits will be set on packets in switched PVCs on the output interface, use the threshold ecn Frame Relay congestion management configuration command. To remove the threshold configuration, use the no form of this command.

threshold ecn {bc | be} percentage

no threshold ecn {bc | be} percentage

Syntax Description

bc

Specifies threshold for committed traffic.

be

Specifies threshold for excess traffic.

percentage

Threshold at which ECN bits will be set on packets, specified as a percentage of maximum queue size.

You must enable Frame Relay switching, using the frame-relay switching global command, before the threshold ecn command will be effective on switched PVCs.

You can configure separate queue thresholds for committed and excess traffic.

Configure the Be ECN threshold so that it is greater than or equal to zero and less than or equal to the Bc ECN threshold. Configure the Bc ECN threshold so that it is less than or equal to 100.

Examples

The following example shows how to configure a Be threshold of 0 and a Bc threshold of 20% on serial interface 1.

interface serial1
 encapsulation frame-relay
 frame-relay congestion-management
  threshold ecn be 0
  threshold ecn bc 20
