Frame Relay Service Configuration Commands on Cisco IOS XR Software

---

This chapter describes the commands used to configure Frame Relay service on Packet-over-SONET/SDH (POS) and serial interfaces for the Cisco XR 12000 Series Router running Cisco IOS XR software.

encap (PVC)

To change the encapsulation for a Frame Relay permanent virtual circuit (PVC), use the encap command in PVC configuration mode. To restore default encapsulation from the Frame Relay main interface, use the no form of this command.

encap [cisco | ietf]

no encap [cisco | ietf]

Syntax Description

cisco	(Optional) Uses Cisco encapsulation, which is a 4-byte header, with 2 bytes to identify the data-link connection identifier (DLCI) and 2 bytes to identify the packet type.
ietf	(Optional) Sets the encapsulation method to comply with the Internet Engineering Task Force (IETF) standard (RFC 1490). Use this keyword when connecting to equipment that belongs to a vendor other than Cisco across a Frame Relay network.

Defaults

The default encapsulation keyword is Cisco.
When this command is not configured, encapsulation is inherited from the Frame Relay main interface.

Command Modes

PVC configuration

Command History

Release	Modification
Release 3.4.0	This command was introduced on the Cisco XR 12000 Series Router.

Usage Guidelines

To use this command, you must be in a user group associated with a task group that includes the proper task IDs. For detailed information about user groups and task IDs, see the Configuring AAA Services on Cisco IOS XR Software module of the Cisco IOS XR System Security Configuration Guide.

Use the encap command to configure encapsulation for a Frame Relay PVC. If this command is not configured, encapsulation is inherited from the Frame Relay subinterface.

This command is available on Packet-over-SONET/SDH (POS) and serial interfaces for this Cisco IOS XR software release.

Task ID

Task ID	Operations
fr	read, write

Examples

The following example shows how to set encapsulation on PVC data-link connection identifier (DLCI) 16 for Packet-over-SONET/SDH (POS) subinterface 0/4/0/1.1:

RP/0/0/CPU0:router(config)# interface POS 0/4/0/1.1

RP/0/0/CPU0:router(config-subif)# pvc 16

RP/0/0/CPU0:router(config-fr-vc)# encap

Related Commands

Command	Description
encapsulation frame-relay	Enables Frame Relay encapsulation.

encapsulation frame-relay

To enable Frame Relay encapsulation, use the encapsulation frame-relay command in interface configuration mode. To disable Frame Relay encapsulation, use the no form of this command.

encapsulation frame-relay [ietf]

no encapsulation frame-relay [ietf]

Syntax Description

ietf	(Optional) Sets the encapsulation method to comply with the Internet Engineering Task Force (IETF) standard (RFC 1490). Use this keyword when connecting to another vendor's equipment across a Frame Relay network.

Defaults

The default encapsulation method is Cisco.

Command Modes

Interface configuration

Command History

Release	Modification
Release 3.4.0	This command was introduced on the Cisco XR 12000 Series Router.

Usage Guidelines

To use this command, you must be in a user group associated with a task group that includes the proper task IDs. For detailed information about user groups and task IDs, see the Configuring AAA Services on Cisco IOS XR Software module of the Cisco IOS XR System Security Configuration Guide.

Use the encapsulation frame-relay command to connect an interface to a Frame Relay network. When this command is configured, incoming packets to the interface are encapsulated and outgoing packets are encapsulated with a Frame Relay header.

A Cisco or IETF encapsulation method controls the Network Layer Protocol Identifier (NLPID) that is added to outgoing packets on the interface. The encapsulation method enabled for an outgoing packet can be changed for each data-link connection identifier (DLCI) per subinterface by using the encap (PVC) command in PVC configuration mode.

When the encapsulation frame-relay command is configured, LMI is enabled by default. To disable LMI use the frame-relay lmi disable command.

The following restrictions apply to the encapsulation frame-relay command upon configuration or removal of the command on an interface:

•When configuring this command, Layer 3 and Layer 2 configurations are not allowed on the interface.

•Before removing this command, all Frame Relay subinterfaces and LMI configuration should be deleted from the interface.

The encapsulation frame-relay command is available on Packet-over-SONET/SDH (POS) and serial interfaces for this Cisco IOS XR software release.

Two message types are supported: status inquiry and status. Status inquiry messages are sent from DTE to DCE. Status messages are sent from DCE to DTE (in response to a status inquiry). The Status (Full) and LIV report types are contained within these messages, and typically there is one status transaction for every five LIV transactions.

show frame-relay pvc

To display statistics about Frame Relay permanent virtual circuits (PVCs), use the show frame-relay pvc command in EXEC mode.

show frame-relay pvc [interface type instance | location node-id] [dlci-number]

Syntax Description

interface type	(Optional) Interface type. For more information, use the question mark (?) online help function.
instance	(Optional) Either a physical interface instance or a virtual interface instance as follows: •Physical interface instance. Naming notation is rack/slot/module/port and a slash between values is required as part of the notation. –rack: Chassis number of the rack. –slot: Physical slot number of the modular services card or line card. –module: Module number. A physical layer interface module (PLIM) is always 0. –port: Physical port number of the interface. Note In references to a Management Ethernet interface located on a route processor card, the physical slot number is alphanumeric (RP0 or RP1) and the module is CPU0. Example: interface MgmtEth0/RP1/CPU0/0. •Virtual interface instance. Number range varies depending on interface type. For more information about the syntax for the router, use the question mark (?) online help function.
location node-id	(Optional) Clears hardware resource counters from the designated node. The node-id argument is entered in the rack/slot/module notation.
dlci-number	(Optional) DLCI number used to identify the PVC. Range is from 16 to 1007.

show interfaces (frame relay)

To display statistics about Frame Relay interfaces, use the show interfaces command in EXEC mode.

show interfaces [type instance | all | local | location node-id] [accounting | brief | detail | summary]

Syntax Description

type	(Optional) Interface type. For more information, use the question mark (?) online help function.
instance	(Optional) Either a physical interface instance or a virtual interface instance as follows: •Physical interface instance. Naming notation is rack/slot/module/port and a slash between values is required as part of the notation. –rack: Chassis number of the rack. –slot: Physical slot number of the modular services card or line card. –module: Module number. A physical layer interface module (PLIM) is always 0. –port: Physical port number of the interface. Note In references to a Management Ethernet interface located on a route processor card, the physical slot number is alphanumeric (RP0 or RP1) and the module is CPU0. Example: interface MgmtEth0/RP1/CPU0/0. •Virtual interface instance. Number range varies depending on interface type. For more information about the syntax for the router, use the question mark (?) online help function.
all	(Optional) Displays interface information for all interfaces. This is the default.
local	(Optional) Displays interface information for all interfaces in the local card.
location node-id	(Optional) Clears hardware resource counters from the designated node. The node-id argument is entered in the rack/slot/module notation.
