Parameters

dlci-number: Virtual circuit number allocated for the frame relay interface, in the range 16 to 1007. The ranges 0 to 15 and 1008 to 1023 are reserved for special purposes.

Description

Use the fr dlci command to configure the virtual circuit for the frame relay interface and enter the virtual circuit view on the frame relay interface.

Use the undo fr dlci command to cancel the configuration. If no virtual circuit is specified, all virtual circuits on the interface are removed.

When the frame relay interface type is DCE, it is necessary to manually configure virtual circuit for interface (either main interface or subinterface).

When the frame relay interface type is DTE, if the interface is a main interface, the system will automatically configure the virtual circuit according to the peer router.

The virtual circuit number on the physical interface is unique.

Parameters

ip: Performs InARP for IP addresses.

dlci-number: Data link connection identifier (DLCI) number, or virtual circuit number, indicating that the inverse address resolution is performed for this DLCI number only, which ranges from 16 to 1007.

Description

Use the fr inarp command to enable InARP for frame relay on the interface.

Use the undo fr inarp command to disable InARP for frame relay on the interface.

By default, InARP for frame relay is enabled on a frame relay interface, as well as on all the PVCs under it.

When frame relay sends data over the interface, it is necessary to map the peer IP address to the local DLCI number. Such a mapping can be specified manually or completed through InARP automatically.

· To enable or disable InARP for all virtual circuits of interfaces, use the command without any parameter.

· To enable or disable InARP for the specified virtual circuit, use the command with the dlci-number argument.

· Enabling InARP on an interface or subinterface also enables InARP on all virtual circuits of the interface or subinterface. In this case, to disable InARP on a specific virtual circuit of the interface or subinterface, use undo fr inarp ip dlci-number command.

· Using the undo fr inarp command to disable InARP on an interface also disables InARP on all the virtual circuits on the interface. In this case, to enable InARP on a specific virtual circuit of the interface, use the fr inarp ip dlci-number command.

· Enabling InARP on an interface also enables InARP on all its subinterfaces.

Parameters

dce: Sets the frame relay interface type to DCE (Data Circuit-terminating Equipment).

dte: Sets the frame relay interface type to DTE (Data Terminal Equipment).

Description

Use the fr interface-type command to set the frame relay interface type.

Use the undo fr interface-type command to restore the default frame relay interface type.

By default, the frame relay interface type is DTE.

In frame relay, two communicating parties, the user side and the network side, exist. The user side is called “Data Terminal Equipment (DTE)”, and the network side is called “Data Communications Equipment (DCE)”. If the router is used for frame relay switching, the frame relay interface should operate in DCE mode.

Parameters

n391-value: Value of counter N391, which ranges from 1 to 255.

Description

Use the fr lmi n391dte command to configure the full status polling interval at the DTE side.

Use the undo fr lmi n391dte command to restore the default.

By default, the full status polling interval is 6.

The DTE sends a Status-Enquiry message at a regular interval set by T391 to the DCE. Status-Enquiry messages fall into the following types: link integrity verification messages and full link status enquiry messages. N391 defines that the ratio of sent link integrity verification messages to sent full link status enquiry messages is (N391–1):1.

Parameters

n392-value: The Error threshold, which ranges from 1 to 10.

Description

Use the fr lmi n392dce command to set N392 parameter at the DCE side.

Use the undo fr lmi n392dce command to restore the default.

By default, the parameter value is 3.

The DCE requires the DTE to send a Status-Enquiry message at a regular interval (set by T392). If the DCE does not receive the Status-Enquiry message within a period of time, the error counter on DCE increments by one. If the errors exceed the threshold, the DCE would consider the physical channels and all the DLCIs to be unavailable.

N392 and N393 together define the “error threshold”. N393 defines the number of events observed and N392 defines the error threshold for that number (N393). If the number of errors that occurred to the DCE reaches N392 in N393 events, DCE will consider the errors have reached the threshold and declare the physical channels and all DLCIs to be unavailable.

N392 should be less than N393 at the DCE side.

Description

Use the fr lmi n392dte command to set N392 parameter at the DTE side.

Use the undo fr lmi n392dte command to restore the default.

By default, the parameter is 3.

The DTE sends a Status-Enquiry message at a regular interval to the DCE to inquire the link status. On receiving this packet, the DCE will immediately send a Status-Response packet. If the DTE does not receive the response packet in the specified time, it will record the error by adding 1 to the error count. If the errors exceed the threshold, the DTE will consider that the physical channels and all the DLCIs to be unavailable.

N392 and N393 together define the “error threshold”. N393 indicates the number of events observed and N392 indicates the error threshold for that number (N393). If N392 errors occurred in N393 Status-Enquiry messages in the DTE, the DTE would consider that the error had exceeded the threshold and declare the physical channels and all DLCIs to be unavailable.

N392 at DTE side should be less than N393 at the DTE side.

Description

Use the fr lmi n393dte command to set N393 parameter at the DTE side.

Use the undo fr lmi n393dte command to restore the default.

By default, the parameter value is 4.

The DTE sends a Status-Enquiry message at a regular interval to the DCE to inquire the link status. On receiving this message, the DCE will immediately send a Status message. If the DTE does not receive the Status message in the specified time, it will record the error by adding 1 to the error count. If the errors exceed the threshold, the DTE will consider that the physical channels and all the DLCIs to be unavailable.

N392 and N393 together define the “error threshold”. N393 indicates the number of events observed and N392 indicates the error threshold for that number (N393). If N392 errors occurred in N393 Status-Enquiry messages in the DTE, the DTE would consider that the error count had exceeded the threshold and declare the physical channels and all DLCIs to be unavailable.

N392 at the DTE side should be less than N393 at the DTE side.

Use the fr lmi type command to configure the frame relay LMI protocol type.

Use the undo fr lmi type command to restore the default.

By default, the LMI protocol type is q933a.

The LMI protocol maintains the frame relay protocol PVC table, including notifying PVC increasing, detecting PVC deleting, monitoring PVC status changing, and verifying link integrity. The system usually supports three standard LMI protocols ITU-T Q.933 Appendix A, ANSI T1.617 Appendix D, and nonstandard-compatible LMI protocol.

Default level

2: System level

Parameters

ip-address: Peer IP address.

dlci-number: Local virtual circuit number, in the range 16 to 1007.

broadcast: Specifies that broadcast packets can be sent by using the map.

ietf: Indicates that the map adopts IETF encapsulation format.

nonstandard: Indicates that the map adopts a non-standard compatible encapsulation format.

Description

Use the fr map ip command to add an IP address map entry for frame relay.

Use the undo fr map ip command to remove an IP address map entry for frame relay.

By default, no static address map entry exists and InARP is enabled.

You can create an address map manually or by using InARP. InARP is suitable for a complex network where the remote device also supports InARP. When the number of remote hosts is small or when default routes exist, however, manual map creation is preferred.

Default level

2: System level

Parameters

ietf: Default encapsulation format according to the Internet Engineering Task Force (IETF) standard.

nonstandard: Nonstandard compatible encapsulation format.

Description

Use the link-protocol fr command to encapsulate interface link layer protocol as frame relay.

By default, the link-layer protocol encapsulated on the interface is PPP, and the frame relay encapsulation format is IETF.

The frame relay encapsulation can be either ietf or nonstandard. IETF encapsulation conforms to RFC 1490, and it supports the IETF standard and is compatible with dedicated encapsulation format of mainstream routers.

If you encapsulate a frame relay interface using any of these frame relay formats, the packets are encapsulated in the frame relay format before they are forwarded through the interface. Two routers can communicate with each other if the interfaces of both sides can recognize packets in both of the formats even if they are encapsulated using different frame relay formats. If an interface on one side cannot recognize packets of both formats, you need to encapsulate the two interfaces using the same frame relay format.

CAUTION:

Before switching the link layer protocol of an interface (from PPP/HDLC to FR or the other way around), manually remove all configurations related to QoS and ACL policies on the interface first.

# Configure frame relay encapsulation on interface Serial 4/1/8:10 and select the nonstandard encapsulation compatible format.

Description

Use the interface mfr command to create a multilink frame relay bundle interface or subinterface and enter the interface view.

Use the undo interface mfr command to delete a specified multilink frame relay bundle interface or subinterface.

By default, no multilink frame relay interface or subinterface exists. On creation, the type of an MFR subinterface is p2mp by default.

To create an MFR subinterface successfully, make sure the MFR interface already exists.

To use the undo interface mfr command to delete an MFR interface, delete all physical interfaces from the MFR interface.

For MFR interface, if one bundle link in up state exists, the MFR physical state is up. Moreover, all bundle links should be tagged as down before the bundle is down. The link layer protocol on MFR interface is determined by LMI packet negotiation.

2: System level

Parameters

interface-number: MFR interface number.

Description

Use the link-protocol fr mfr command to configure the current physical interface as an MFR bundle link and bind it to an MFR interface.

By default, an interface is not bound to any MFR interface.

When this command is configured, the specified MFR interface must exist. A maximum of 16 physical interfaces can be bundled onto an MFR interface, but only 12 of them stay up at the same time.

To delete a physical interface from an MFR interface, use the link-protocol command to apply a link layer protocol of non-frame relay MFR to the interface.

After a physical interface is encapsulated as MFR format, the interface belongs to MFR and is not allowed to be configured using the commands related to FR except MFR.

Parameters

number: The maximum times that a bundle link can resend hello messages, in the range 1 to 5.

Description

Use the mfr retry command to set the maximum times that a frame relay bundle link can resend hello message when waiting for a hello acknowledgement message.

Use the undo mfr retry command to restore the default.

By default, the maximum times that a frame relay bundle link can resend hello message is twice.

The bundle link sustains link status by periodically sending hello message to the peer end. If the times that a bundle link resends hello message reach the maximum without receiving acknowledgement from the peer, the system will regard the link protocol on the bundle link to be malfunctioning.

You can configure this command only after the link-protocol fr mfr command is used to associate a frame relay bundle link interface with a frame relay bundle.
