Prerequisites for Configuring Frame Relay

Before configuring Frame Relay, be sure that the following conditions are met:

You must be in a user group associated with a task group that includes the proper task IDs for Frame Relay commands. Task IDs for commands are listed in the Cisco IOS XR Interface and Hardware Component Command Reference.

Your hardware must support POS or serial interfaces.

You have enabled Frame Relay encapsulation on your interface with the encapsulation frame relay command, as described in the appropriate chapter:

To enable Frame Relay encapsulation on a multilink bundle interface, see the "Configuring Multilink Frame Relay Bundle Interfaces" section in this module.

To enable Frame Relay encapsulation on a POS interface, see the "Configuring POS Interfaces on Cisco IOS XR Software" module in this manual.

To enable Frame Relay encapsulation on a serial interface, see the "Configuring Serial Interfaces on Cisco IOS XR Software" module in this manual.

Information About Frame Relay Interfaces

The following sections explain the various aspects of configuring Frame Relay interfaces:

Frame Relay Encapsulation

Multilink Frame Relay

End-to-End Fragmentation (FRF.12)

Frame Relay Encapsulation

On the Cisco XR 12000 Series Router, Frame Relay is supported on POS and serial main interfaces, and on PVCs that are configured under those interfaces. To enable Frame Relay encapsulation on an interface, use the encapsulation frame-relay command in interface configuration mode.

Frame Relay interfaces support two types of encapsulated frames:

Cisco (this is the default)

IETF

Use the encap command in Frame Relay PVC configuration mode to configure Cisco or IETF encapsulation on the main interface.


Note If the encapsulation type is not configured explicitly for a PVC with the encap command, then that PVC inherits the encapsulation type from the main interface.


The encapsulation frame relay and encap commands are described in the following chapters:

To enable Frame Relay encapsulation on a POS interface, see the "Configuring POS Interfaces on Cisco IOS XR Software" module in this manual.

To enable Frame Relay encapsulation on a serial interface, see the "Configuring Serial Interfaces on Cisco IOS XR Software" module in this manual.

When an interface is configured with Frame Relay encapsulation and no additional configuration commands are applied, the default interface settings shown in Table 1 are present. These default settings can be changed by configuration as described in this module.

LMI

The Local Management Interface (LMI) protocol monitors the addition, deletion, and status of PVCs. LMI also verifies the integrity of the link that forms a Frame Relay User-Network Interface (UNI).

Frame Relay interfaces supports the following types of LMI on UNI interfaces:

ANSI—ANSI T1.617 Annex D

Q.933—ITU-T Q.933 Annex A

Cisco

Use the frame-relay lmi-type command to configure the LMI type to be used on an interface.


Note The LMI type must match on both ends of a Frame Relay connection. We recommend using the default LMI type.


If your router functions as a switch connected to another non-Frame Relay router, use the frame-relay intf-type dce command to configure the LMI type to support data communication equipment (DCE).

If your router is connected to a Frame Relay network, use the frame-relay intf-type dte command to configure the LMI type to support data terminal equipment (DTE).


Note LMI type auto-sensing is supported on DTE interfaces by default.


Use the show frame-relay lmi command in EXEC mode to display statistical information for the Frame Relay interfaces in your system. You can modify the error threshold, event count, and polling verification timer and then use the show frame-relay lmi command to gather information that can help you monitor and troubleshoot Frame Relay interfaces.

If the LMI type is cisco (the default LMI type), the maximum number of PVCs that can be supported under a single interface is related to the MTU size of the main interface. Use the following formula to calculate the maximum number of PVCs supported on a card or SPA:

MTU - 13/8 = maximum number of PVCs

The default number of PVCs supported on POS PVCs with cisco LMI is 557.

For non-Cisco LMI types, up to 992 PVCs are supported under a single main interface.


Note If a specific LMI type is configured on an interface, use the no frame-relay lmi-type {ansi | cisco | q933a} command to bring the interface back to the default LMI type.

Multilink Frame Relay

Multilink Frame Relay is supported only on the following shared port adapters (SPAs):

Cisco 1-Port Channelized STM-1/OC-3 shared port adapter

2-Port and 4-Port Channelized T3 SPA

A multilink Frame Relay interface is part of a multilink bundle that allows Frame Relay encapsulation on its interfaces. You create a multilink Frame Relay interface by configuring the following components:

MgmtMultilink controller

Multilink bundle interface that allows Frame Relay encapsulation

Bundle identifier name

Multilink Frame Relay subinterfaces

Bundle interface bandwidth class

T3 Controller

T1 Controller

Serial interfaces

MgmtMultilink Controller

You configure a multilink bundle under a controller, using the following commands:

controller MgmtMultilink rack/slot/bay/controller-id

bundle bundleId

This configuration creates the controller for a generic multilink bundle. The controller ID number is the zero-based index of the controller chip. Currently, the SPAs that support multilink Frame Relay have only one controller per bay; therefore, the controller ID number is always zero (0).

Multilink Bundle Interface

After you create the multilink bundle, you create a multilink bundle interface that allows Frame Relay encapsulation, using the following commands:

interface Multilink rack/slot/bay/controller-id/bundleId

encapsulation frame-relay

This configuration allows you to create multilink Frame Relay subinterfaces under the multilink bundle interface.


Note After you set the encapsulation on a multilink bundle interface to Frame Relay, you cannot change the encapsulation. Also, you cannot change the encapsulation on a multilink bundle interface that has member links or on any member links associated with a multilink bundle.


Bundle Identifier Name


Note Bundle identifier name is configurable only under Frame Relay Forum 16.1 (FRF 16.1).


The bundle identifier (bid) name value identifies the bundle interface at both endpoints of the interface. The bundle identifier name is exchanged in the information elements to ensure consistent link assignments. The bundle identifier name can be up to 50 characters including the null termination character. The bundle identifier name is configured at the bundle interface level and is applied to each member link.

You configure the bundle identifier name using the following commands:

interface Multilink rack/slot/bay/controller-id/bundleId

frame-relay multilink bid bundle-id-name

Multilink Frame Relay Subinterfaces

You configure a multilink Frame Relay subinterface, using the following command:

interface Multilink rack/slot/bay/controller-id/bundleId.subinterace
[point-to-point | l2transport ]

You can configure up to 992 subinterfaces on a multilink bundle interface.


Note You configure specific Frame Relay interface features at the subinterface level.


Multilink Frame-Relay Subinterface Features

The following commands are available to set specific features on a multilink Frame Relay bundle subinterface:

encapsulation frame-relay

multilink fragment-size value

mtu MTU size

desription

shutdown

bandwidth bandwidth

service-policy input|output/policymap-name


Note Only a hierarchical policy map that includes match fr-dlci may be attached to a multilink Frame Relay bundle interface.


Bundle Interface Bandwidth Class


Note Bandwidth class is configurable only under Frame Relay Forum 16.1 (FRF 16.1).


You can configure one of three types of bandwidth classes on a multilink Frame Relay interface:

a—Bandwidth Class A

b—Bandwidth Class B

c—Bandwidth Class C

When Bandwidth Class A is configured and one or more member links are up (PH_ACTIVE), the bundle interface is also up and BL_ACTIVATE is signaled to the Frame Relay connections. When all the member links are down, the bundle interface is down and BL_DEACTIVATE is signaled to the Frame Relay connections.

When Bandwidth Class B is configured and all the member links are up (PH_ACTIVE), the bundle interface is up and BL_ACTIVATE is signaled to the Frame Relay connections. When any member link is down, the bundle interface is down and BL_ACTIVATE is signaled to the Frame Relay connections.

When Bandwidth Class C is configured, you must also set the bundle link threshold to a value between 1 and 255. The threshold value is the minimum number of links that must be up (PH_ACTIVE) for the bundle interface to be up and for BL_ACTIVATE to be signaled to the Frame Relay connections. When the number of links that are up falls below this threshold, the bundle interface goes down and BL_DEACTIVATE is signaled to the Frame Relay connections. When 1 is entered as the threshold value, the behavior is identical to Bandwidth Class A. If you enter a threshold value that is greater than the number of member links that are up, the bundle remains down.

You configure the bandwidth class for a Frame Relay multilink bundle interface using the following commands:

interface Multilink rack/slot/bay/controller-id/bundleId.subinterace
[point-to-point | l2transport ]

frame-relay multilink bandwidth-class a | b | c threshold

The default is a (Bandwidth Class A).

T3 Controller

After a multilink bundle subinterface is configured, you create the T3 controller, using the following commands:

controller T3 rack/slot/bay/port

mode t1

clock source line

T1 Controller

After a T3 controller is configured, you create the T1 controllers, channel groups, and timeslots, using the following commands:

controller T1 rack/slot/bay/port/t1-time-slot-within-t3

channel-group channel-group-id

timeslot 1-24

Serial Interfaces

After the T3 and T1 controllers are configured, you can add serial interfaces to the multilink Frame Relay bundle subinterface by configuring the serial interface, encapsulating it as multilink Frame Relay (mfr), and assigning it to the bundle interface (specified by the multilink group number).

You configure a multilink Frame Relay serial interface using the following commands:

interface serial rack/slot/module/port/t1-num:channel-group-number

encapsulation mfr

multilink group group number


Note All serial links in an MFR bundle inherit the value of the mtu command from the multilink interface. Therefore, you should not configure the mtu command on a serial interface before configuring it as a member of an MFR bundle. The Cisco IOS XR software blocks attempts to configure a serial interface as a member of an MFR bundle if the interface is configured with a non-default MTU value as well as attempts to change the mtu command value for a serial interface that is configured as a member of an MFR bundle.


Show Commands

You can verify a multilink Frame Relay serial interface configuration using the following show commands:

show frame-relay multilink location

show frame-relay multilink interface serial

The following example shows the display output of the show frame-relay multilink location command:

RP/0/0/CPU0:router# show frame-relay multilink  location  0/4/cpu0
Member interface: Serial0/4/2/0/9:0, ifhandle 0x05007b00 
HW state = Up, link state = Up
Member of bundle interface Multilink0/4/2/0/2 with ifhandle 0x05007800 
 
   
Bundle interface: Multilink0/4/2/0/2, ifhandle 0x05007800 
    Member Links: 4 active, 0 inactive
    State = Up,   BW Class = C (threshold   3)
    Member Links:
    Serial0/4/2/0/12:0, HW state = Up, link state = Up
    Serial0/4/2/0/11:0, HW state = Up, link state = Up
    Serial0/4/2/0/10:0, HW state = Up, link state = Up
    Serial0/4/2/0/9:0, HW state = Up, link state = Up
 
   
Member interface: Serial0/4/2/0/10:0, ifhandle 0x05007c00 
HW state = Up, link state = Up
Member of bundle interface Multilink0/4/2/0/2 with ifhandle 0x05007800 
 
   
Member interface: Serial0/4/2/0/11:0, ifhandle 0x05007d00 
HW state = Up, link state = Up
Member of bundle interface Multilink0/4/2/0/2 with ifhandle 0x05007800 
 
   
Member interface: Serial0/4/2/0/12:0, ifhandle 0x05007e00 
HW state = Up, link state = Up
Member of bundle interface Multilink0/4/2/0/2 with ifhandle 0x05007800 
 
   

The following example shows the display output of

RP/0/0/CPU0:router# show frame-relay multilink interface serial 0/4/2/0/10:0 
 
   
Member interface: Serial0/4/2/0/10:0, ifhandle 0x05007c00 
HW state = Up, link state = Up
Member of bundle interface Multilink0/4/2/0/2 with ifhandle 0x05007800 

End-to-End Fragmentation (FRF.12)

You can configure an FRF.12 end-to-end fragmentation connection using the data-link connection identifier (DLCI). However, it must be done on a channelized frame relay serial interface.


Note The fragment end-to-end command is not allowed on Packet-over-SONET/SDH (POS) interfaces or under the DLCI of a multilink Frame Relay bundle interface.


You configure FRF.12 end-to-end fragmentation on a DLCI connection using the following command:

fragment end-to-end fragment-size

The fragment-size argument defines the size of the fragments, in bytes, for the serial interface.


Note On a DLCI connection, we highly recommend that you configure an egress service policy that classifies packets into high and low priorities, so that interleaving of high-priority and low-priority fragments occurs.


Configuring Frame Relay

The following sections describe how to configure Frame Relay interfaces.

Modifying the Default Frame Relay Configuration on an Interface

Disabling LMI on an Interface with Frame Relay Encapsulation

Configuring Multilink Frame Relay Bundle Interfaces

Configuring FRF.12 End-to-end Fragmentation on a Channelized Frame Relay Serial Interface

Modifying the Default Frame Relay Configuration on an Interface

Perform this task to modify the default Frame Relay parameters on a Packet-over-SONET/SDH (POS), multilink, or serial interface with Frame Relay encapsulation.

Prerequisites

Before you can modify the default Frame Relay configuration, you need to enable Frame Relay on the interface, as described in the following chapters:

To enable Frame Relay encapsulation on a POS interface, see the "Configuring POS Interfaces on Cisco IOS XR Software" module in this manual.

To enable Frame Relay encapsulation on a serial interface, see the "Configuring Serial Interfaces on Cisco IOS XR Software" module in this manual.

Restrictions

The LMI type must match on both ends of the connection for the connection to be active.

Before you can remove Frame Relay encapsulation on an interface and reconfigure that interface with PPP or cHDLC encapsulation, you need remove all interfaces, subinterface, ILMI, and Frame Relay configuration from that interface.

Step 3 

frame-relay intf-type [dce | dte]

Example:
RP/0/0/CPU0:router(config-if)# frame-relay 
intf-type dce

Configures the type of support provided by the interface.

If your router functions as a switch connected to another router, use the frame-relay intf-type dce command to configure the LMI type to support data communication equipment (DCE).

If your router is connected to a Frame Relay network, use the frame-relay intf-type dte command to configure the LMI type to support data terminal equipment (DTE).

Note The default interface type is DTE.

Step 4 

frame-relay lmi-type {ansi | q933a | cisco}

Example:
RP/0/0/CPU0:router(config-if)# frame-relay 
lmi-type ansi

Selects the LMI type supported on the interface.

Enter the frame-relay lmi-type ansi command to use LMI as defined by ANSI T1.617a-1994 Annex D.

Enter the frame-relay lmi-type cisco command to use LMI as defined by Cisco (not standard).

Enter the frame-relay lmi-type q933a command to use LMI as defined by ITU-T Q.933 (02/2003) Annex A.

Note The default LMI type is Cisco.

Step 5 

encap [cisco | ietf]

Example:

RP/0/0/CPU0:router (config-subif)# encap ietf

Configures the encapsulation for a Frame Relay PVC.

Note If the encapsulation type is not configured explicitly for a PVC, then that PVC inherits the encapsulation type from the main POS interface.

Step 6 

end

or

commit

Example:

RP/0/0/CPU0:router(config-if)# end

or

RP/0/0/CPU0:router(config-if)# commit

Saves configuration changes.

When you issue the end command, the system prompts you to commit changes:

Uncommitted changes found, commit them before 
exiting(yes/no/cancel)? 
[cancel]:
 
        

Entering yes saves configuration changes to the running configuration file, exits the configuration session, and returns the router to EXEC mode.

Entering no exits the configuration session and returns the router to EXEC mode without committing the configuration changes.

Entering cancel leaves the router in the current configuration session without exiting or committing the configuration changes.

Use the commit command to save the configuration changes to the running configuration file and remain within the configuration session.

Step 7 

show interfaces type [instance]

Example:

RP/0/0/CPU0:router# show interface pos 0/4/0/1

(Optional) Verifies the configuration for the specified interface.

Disabling LMI on an Interface with Frame Relay Encapsulation

Perform this task to disable LMI on interfaces that have Frame Relay encapsulation.


Note LMI is enabled by default on interfaces that have Frame Relay encapsulation enabled. To reenable LMI on an interface after it has been disabled, use the no frame-relay lmi disable command in interface configuration mode.

(Optional) Verifies that LMI is disabled on the specified interface.

Configuring Multilink Frame Relay Bundle Interfaces

Perform these steps to configure a multilink Frame Relay bundle interface and its subinterfaces.

Restrictions

All member links in a multilink Frame Relay bundle interface must be of the same type. The member links must have the same framing type, such as point-to-point, and they must have the same bandwidth class.

All links must be connected to the same line card or SPA at the far end.

All serial links in an MFR bundle inherit the value of the mtu command from the multilink interface. Therefore, you should not configure the mtu command on a serial interface before configuring it as a member of an MFR bundle. The Cisco IOS XR software blocks the following:

Attempts to configure a serial interface as a member of an MFR bundle if the interface is configured with a non-default MTU value.

Attempts to change the mtu command value for a serial interface that is configured as a member of an MFR bundle.

DETAILED STEPS

 
Command or Action
Purpose

Step 1 

config
Example:

RP/0/0/CPU0:router# config

Enters global configuration mode.

Step 2 

controller MgmtMultilink rack/slot/bay/controller-id

Example:

RP/0/0/CPU0:router(config)# controller MgmtMultilink 0/1/0/0

Creates the controller for a generic multilink bundle in the rack/slot/bay/controller-id notation and enters the multilink management configuration mode. The controller ID number is the zero-based index of the controller chip. Currently, the SPAs that support multilink Frame Relay have only one controller per bay; therefore, the controller ID number is always zero (0).

Step 3 

exit
Example:

RP/0/0/CPU0:router(config-mgmtmultilink)# exit

Exits the multilink management configuration mode.

Step 4 

controller t3 instance

Example:

RP/0/0/CPU0:router(config)# controller t3 0/1/0/0

Specifies the T3 controller name in the rack/slot/module/port notation and enters T3 configuration mode.

Step 5 

mode type

Example:

RP/0/0/CPU0:router(config-t3)# mode t1

Configures the type of multilinks to channelize; for example, 28 T1s.

Step 6 

clock source {internal | line}

Example:

RP/0/0/CPU0:router(config-t3)# clock source internal

(Optional) Sets the clocking for individual E3 links.

Note The default clock source is internal.

Note When configuring clocking on a serial link, you must configure one end to be internal, and the other end to be line. If you configure internal clocking on both ends of a connection, framing slips occur. If you configure line clocking on both ends of a connection, the line does not come up.

Step 7 

exit

Example:

RP/0/0/CPU0:router(config-t3)# exit

Exits T3/E3 or T1/E1 controller configuration mode.

Step 8 

controller t1 instance

Example:

RP/0/0/CPU0:router(config)# controller t1 0/1/0/0/0

Enters T1 configuration mode.

Step 9 

channel-group channel-group-number

Example:

RP/0/0/CPU0:router(config-t1)# channel-group 0

Creates a T1 channel group and enters channel group configuration mode for that channel group.

Step 10 

timeslots range

Example:

RP/0/0/CPU0:router(config-t1-channel_group)# timeslots 1-24

Associates one or more DS0 time slots to a channel group and creates an associated serial subinterface on that channel group.

Range is from 1 to 24 time slots.

You can assign all 24 time slots to a single channel group, or you can divide the time slots among several channel groups.

Note Each individual T1 controller supports a total of 24 DS0 time slots.

Step 11 

exit

Example:

RP/0/0/CPU0:router(config-t1-channel_group)# exit

Exits channel group configuration mode.

Step 12 

exit

Example:

RP/0/0/CPU0:router(config-t1)# exit

Exits T1 configuration mode.

Step 13 

interface Multilink 
rack/slot/bay/controller-id/bundleId
Example:

RP/0/0/CPU0:router(config)# interface Multilink 0/1/0/0/100

Creates a multilink bundle interface where you can specify Frame Relay encapsulation for the bundle. You create multilink Frame Relay subinterfaces under the multilink bundle interface.

Step 14 

encapsulation frame-relay | ppp

Example:

Router(config-if)# encapsulation frame-relay

Specifies the encapsulation type with the one of the following keywords:

frame-relay—Frame Relay network protocol

ppp—Point-to-Point Protocol

Step 15 

frame-relay multilink bid bundle-id-name
Example:
Router(config-if)# frame-relay multilink bid 
MFRBundle

Specifies the name of a multilink Frame Relay interface.

Step 16 

frame-relay multilink bandwidth-class a | b | c 
threshold
Example:
Router(config-if)# frame-relay multilink 
bandwidth-class a 

Configures one of three types of bandwidth classes on a multilink Frame Relay interface:

a—Bandwidth Class A

b—Bandwidth Class B

c—Bandwidth Class C

The default is a (Bandwidth Class A).

Step 17

DETAILED STEPS

 
Command or Action
Purpose

Step 1 

config
Example:

RP/0/0/CPU0:router# config

Enters global configuration mode.

Step 2 

controller t3 instance

Example:

RP/0/0/CPU0:router(config)# controller t3 0/1/0/0

Specifies the T3 controller name in the rack/slot/module/port notation and enters T3 configuration mode.

Step 3 

mode type

Example:

RP/0/0/CPU0:router(config-t3)# mode t1

Configures the type of multilinks to channelize; for example, 28 T1s.

Step 4 

clock source {internal | line}

Example:

RP/0/0/CPU0:router(config-t3)# clock source internal

(Optional) Sets the clocking for individual E3 links.

Note The default clock source is internal.

Note When configuring clocking on a serial link, you must configure one end to be internal, and the other end to be line. If you configure internal clocking on both ends of a connection, framing slips occur. If you configure line clocking on both ends of a connection, the line does not come up.

Step 5 

exit

Example:

RP/0/0/CPU0:router(config-t3)# exit

Exits T3/E3 or T1/E1 controller configuration mode.

Step 6 

controller t1 instance

Example:

RP/0/0/CPU0:router(config)# controller t1 0/1/0/0/0

Enters T1 configuration mode.

Step 7 

channel-group channel-group-number

Example:

RP/0/0/CPU0:router(config-t1)# channel-group 0

Creates a T1 channel group and enters channel group configuration mode for that channel group.

Step 8 

timeslots range

Example:

RP/0/0/CPU0:router(config-t1-channel_group)# timeslots 1-24

Associates one or more DS0 time slots to a channel group and creates an associated serial subinterface on that channel group.

Range is from 1 to 24 time slots.

You can assign all 24 time slots to a single channel group, or you can divide the time slots among several channel groups.

Note Each individual T1 controller supports a total of 24 DS0 time slots.

Step 9 

exit

Example:

RP/0/0/CPU0:router(config-t1-channel_group)# exit

Exits channel group configuration mode.

Step 10 

exit

Example:

RP/0/0/CPU0:router(config-t1)# exit

Exits T1 configuration mode.

Step 11

Specifies the complete interface number with the rack/slot/module/port/T3Num/T1num:instance notation.

Step 12 

encapsulation frame-relay | ppp

Example:

RP/0/0/CPU0:Router(config-if)# encapsulation frame-relay

Specifies the encapsulation type with the one of the following keywords:

frame-relay—Frame Relay network protocol

ppp—Point-to-Point Protocol

Step 13

Example:

RP/0/0/CPU0:router (config-subif)# pvc 100

Creates a POS permanent virtual circuit (PVC) and enters Frame Relay PVC configuration submode.

Replace dlci with a PVC identifier, in the range from 16 to 1007.

Note Only one PVC is allowed per subinterface.

Step 17 

service-policy {input | output} policy-map

Example:

RP/0/0/CPU0:router(config-fr-vc)# service-policy output policy-mapA

Attaches a policy map to an input subinterface or output subinterface. When attached, the policy map is used as the service policy for the subinterface.
