Frame Relay Configuration Procedures

This section describes the following Frame Relay concepts and general configuration procedures:

• Provisioning Frame Relay Ports

• Partitioning Port Resources Between Controllers

• Selecting the Port Signaling Protocol

• Provisioning and Managing SPVCs

General Information

To do the procedures in this chapter you must start a CLI session on the appropriate MPSM card by logging in with a username and password with GROUP 1 privileges or higher. For detailed information about usernames, passwords, and logging into the CLI, refer to the Cisco MGX 8800/8900 Series Configuration Guide, Release 5.2.

The descriptions and procedures in this chapter operate in the Frame Relay Service CLI context. See Chapter 7, "Command Reference" for detailed descriptions about the MPSM-T3E3-155 and MPSM-16-T1E1 Frame Relay service commands and parameters.

See Table 1-2 in Chapter 1, "Introduction" for a list of the MPSM-T3E3-155 and MPSM-16-T1E1 model numbers, back cards, and the number of possible connections.

Some of the procedures in this section use PXM commands and PNNI commands. Refer to the Cisco MGX 8800/8900 Series Command Reference, Release 5.2 for descriptions of the PXM and PNNI commands and parameters.

For more information on port signaling, refer to the Cisco MGX 8800/8900 Series Configuration Guide, Release 5.2.

Provisioning Frame Relay Ports

On an MPSM card, a logical port is also called a virtual interface and is represented by the ifNum variable. The cards can have the following types of Frame Relay interfaces:

•Frame Relay —This is a port that sends and receives standard Frame Relay frames as defined by ITU-T Q.922. Multiple virtual circuits (VCs) can terminate on one Frame Relay port and are differentiated by their data-link connection identifiers (DLCIs).

•FrameForwarding—This is a port that sends and receives frame-based traffic that is similar to Frame Relay frames such as HDLC, SDLC, and X.25 over Frame Relay interfaces. You can transport any protocol across an ATM network, as long as it supports the HDLC, SDLC, or X.25 format. Application examples include routers interconnected through PPP, mainframes or hosts connected by X.25/HDLC, SNA/SDLC links, and video CODECs that use a frame-based protocol. Frame Forwarding is often used for the aggregation of point-to-point (PPP) traffic into an ATM network, then exiting the ATM network through an ATM interface over multiple VCs into routers supporting PPP over ATM. Frame Forwarding features include:

–No translation or mapping is attempted between the frame header bits and ATM layer EFCI and CLP bits. Because the port is unable to read the address and control information in the frame, all traffic must be forwarded to one destination frame forwarding port.

–Only one frame forwarding VC is allowed per port.

–If a connection is set up, all frames are routed to and from that connection, otherwise the frame is discarded.

–One set of Frame Relay traffic access parameters (for example, CIR) is configured for the logical port in frame forwarding mode. All arriving frames are treated as if they arrived without a set DE bit. If the frame is determined to exceed committed rate (exceeding CIR), the CLP of all cells associated with that frame is set to indicate low priority. If the frame exceeds the total rate allowed for committed and uncommitted traffic, the frame is discarded.

–Support for PPP encapsulation over AAL5 and frame is based on RFC 1483 and RFC 1490.

Preparing to Add Frame Relay Ports

Before you can add Frame Relay ports, you must perform the following tasks:

•Bring up (activate) and configure the physical lines, for example the line payload type. See the "Setting Up Lines" section in Chapter 2, "Preparing MPSM-T3E3-155 and MPSM-16-T1E1 Cards and Lines for Communication,"

•Channelize SONET, SDH, and DS3 lines into paths. See the "Channelizing MPSM-T3E3-155 SONET, SDH, and DS3 (T3) Lines" in Chapter 2, "Preparing MPSM-T3E3-155 and MPSM-16-T1E1 Cards and Lines for Communication,"

Bringing up a line or path establishes physical layer connectivity between two network devices. When you add a Frame Relay port to a line or path, you enable Frame Relay communication by means of that line.

Adding Frame Relay Ports

To add a Frame Relay port to a line or path, perform the following steps:

Step 1 Establish a configuration session using a username with Group1 privileges or higher.

Step 2 Enter the cc command to start a management session with the active MPSM-T3E3-155 card on which you want to add a port.

Step 3 Identify the line or path number on which you will add the port.

If you are adding a port to a line, enter the dsplns command to determine the line number on which to add the Frame Relay port, as shown in the following MPSM-16-T1E1 example.
M8850_SF.27.MPSM16T1E1[FR].a > dsplns
  Line Line      Line      Line      Length     Valid    Alarm

   1.4    Up     dsx1ESF      NoLoop        1         96 Clear
   1.5    Up     dsx1ESF      NoLoop        1         96 Clear
   1.6    Up     dsx1ESF      NoLoop        1         96 Clear

   1.8    Up     dsx1ESF      NoLoop        1         96 Clear
   ...
If you are adding a port to a path, enter the dsppaths command to determine the path number on which to add the Frame Relay port. The following MPSM-T3E3-155 example shows the DS1 paths previously configured on line 1.1.1. The first two paths are dedicated to a Multilink Frame Relay bundle, but the third one is available for Frame Relay.
M8850_SF.9.MPSM155[FR].a > dsppaths -ds1

    1.1.1:8   ds1     Down      dsx1ESF   NoLoop  Unknown     Down      invalid
    ...
Note You cannot add a port directly on a SONET or SDH line; you must channelize it first.

Step 4 Verify that the Line State, or Admin Status is up (active). If necessary, use the upln or uppath commands to bring up the line or path.

Step 5 Verify that the line/path and port number you want to use is not already configured. To display a list of the configured ports on the card, enter the dspports command.

The dspports command shows the number of all existing ports in the ifNum (interface number) column. When you add a port, you must specify a unique port number on the card. For example, if port number 2 is assigned to line 1.1 (bay 1, line 1), you cannot use port 2 on any other line on that card.

Step 6 Enter the addport command as follows to add a Frame Relay port to an active line or path.
M8850_SF.9.MPSM155[FR].a > addport <ifNum> <path> <portType> <sctId>

Identifies the line or path on which to add the port:

•DS1/E1 or DS3/E3 line: bay.line[:ds1/e1]

•DS3 payload: bay.line[.sts]:[ds1]

•VT payload: bay.line[.sts]:[vtg.vt]

•VT structured: bay.line[.sts]:[tug3.vtg.vt]

where: bay=1, line=1-3, sts=0-3, ds1=1-28,
tug3=1-3, vtg=1-7, vt=1-4(VT15) or 1-3(VT2)

Note Use the dsppaths command to see the path numbers for all available paths. Use the dsplns command to see line numbers for all available lines.

Note On a BNC-3-T3 or BNC-3-E3 back card, you can add a port on a physical line, or on a path. On an SFP-2-155 and the SMB-2-155-EL OC3 back card, you can add a port on a path only.

portType

Specifies the type of port:

•1 = Frame Relay Service

•3 = Frame Forward

sctId

Specifies the number of the Service class template (SCT) for the port:

Range: 0-255

Default: 0

-dlciLen

Specifies the DLCI header length:

•1 = Two-byte DLCI header

•2 = Four-byte DLC header (Broadband ports only)

-flags

Specifies the flags between frames:

•1 = 1 flag

•8 = 128 flags

-rat

This keyword and argument defines the egress service ratio between the high priority and the low priority queues.

Enter the keyword followed by a number that indicates the egress service ratio, in the range from 1 to 15.

•Enter 1 to indicate that no service ratio is configured. In this case, bandwidth is allocated to both the high priority and the low priority queues on demand, which means that traffic is dynamically allocated on a first-come, first-serve basis.

•The default setting is 1. In this case, the traffic of the CBR and rt-VBR service categories is allocated to the high priority queue, while the traffic of the nrt-VBR, ABR, and UBR service categories is allocated to the low priority queue.

-csum

Checksum type indicator:

•1 = crc16

•2 = crc32

-oversub

Oversubscription indicator:

•1 = enable

•2 = disable

-lmiSig

LMI signaling type indicator:

•2 = No Signaling

•3 = StrataLMI

•4 = AnnexAUNI

•5 = AnnexDUNI

•6 = AnnexANNI

•7 = AnnexDNNI

-asynUpdt

Enables or disables asynchronous updates. Asynchronous updates are an extension to the LMI protocol that notify the user immediately of changes in PVC and Multicast status. Before enabling this feature, make sure that any DTE equipment you are connected to supports asynchronous updates from the network.

Asynchronous update control:

•1 = Disable both Asynchronous Status Updates and Unsolicited Full Status

•2 = Enable Asynchronous Status Updates

•3 = Enable Unsolicited Full Status

•4 = Enable Asynchronous Status Updates and Unsolicited Full Status

-elmi

Enable or disable enhanced LMI. Enhanced LMI enables the automatic exchange of Frame Relay QoS parameter information between the DTE and DCE. When enabled on both the DTE and the MPSM port, this allows the DTE device to learn QoS parameters from the frame relay port and use them for traffic shaping, configuration, or management purposes. Enter a number to enable/disable enhanced LMI on the port.

•1 = enable

•2 = disable

-segLmi

Segmented LMI control:

•1 = enable

•2 = disable

-t391

T391 timer. This is the Link Integrity Verification polling timer. The user (DTE) sends Status Enquiry messages to the network (DCE) every T391 seconds. An error is recorded if a Status message is not received within T391 seconds. The T391 counter always applies to the user equipment. It applies to the user and network if NNI bidirectional polling is present. Range 5 to 30.

-t392

T392 timer. This is the Polling Verification timer. The network (DCE) expects Status Enquiry messages from the user (DTE) every T392 seconds. If the network does not receive a Status Enquiry message from the user within T392 seconds and the timer expires, then the network records a missing Status Enquiry message by incrementing the N392 counter. This timer value must be set greater than the T391 timer. The T392 timer always applies to the network. It applies to the network and user if NNI bidirectional polling is present. Range 5 to 30.

-n391

N391 counter. This setting establishes the Full Status (status of all PVCs) polling cycle. The user (DTE) sends a Full Report Status Enquiry to the network (DCE) every N391 polls. The N391 counter always applies to the user equipment. It applies to the user and network if NNI bidirectional polling is present. Range1 to 255. Default: 6

-n392

N392 counter. This setting specifies the UNI/NNI error threshold. This is the number of errors during N393 events that will cause an error condition. This counter should be less than or equal to the N393 counter. This counter can apply to both the user (DTE) and the network (DCE). Range 1to 10.

-n393

N393 counter. This setting is the monitored UNI/NNI events count, which must be greater than the N392 counter. N392 errors during N393 events will cause an error condition. If the N393 counter is set to a value much less than the N391 counter, the port could go in and out of an error condition without notification to either the user equipment or the network. This counter can apply to both the user (DTE) and the network (DCE). The value of this parameter should be greater than that for the -n392 parameter. Range: 1-10.

-ds0speed

Specifies the speed of the DS0 channel:

•1 = 56 Kbps

•2 = 64 Kbps.

-ds0beg

Specifies the beginning DS0 number:

•T1 paths: 1- 24

•E1MF and E1CRCMF paths: 2-16, 18-32 (17 is reserved)

•other E1 paths = 2-32

-ds0num

Specifies the number DS0 time slots that will follow the beginning DS0:

•T1 paths: 1- 24

•E1MF and E1CRCMF paths: 1-30

•other E1 paths: 1-31

-fragEnable

Enables or disables fragmentation on the port.

•1 = enable

•2 = disable

-fragSize

Specifies the size of the fragments in bytes:

•40

•64

•128

•256

•512

-hdlcinv

Enables/disables HDLC inversion on the port:

•1 = enable

•2 = disable

In the following example, the user adds Frame Relay port 113 to DS1 path 1.1.1:3, using the default SCT:
M8850_SF.9.MPSM155[FR].a > addport 113 1.1.1:3 1 0
Step 7 Enter the dspports command to verify that the port you added appears in the ifNum (interface number) column. The following example confirms the addition of port 113:

Partitioning Port Resources Between Controllers

After you add a Frame Relay port, you can define how the port resources are to be used by the PNNI controller. Although the Cisco MGX 8850/8830 software allows you to distribute port resources to multiple controllers, the PNNI controller is the only controller supported on Frame Relay ports in Release 5 of the MPSM-T3E3-155. Therefore, you assign all resources to the PNNI controller. These resources include the following:

•Range of DLCI values

•Maximum percent of bandwidth in the ingress and egress directions

•Maximum number of connections

•Minimum and Maximum DLCI values

You configure partitions to control how these connection resources are distributed among the switch, card, and ports within the Cisco MGX 8850/8830 switch. Without these partitions, two or three busy ports could consume all of the available connections, thereby disabling communication on all other ports.

A partition is automatically added when you add a port. This new partition has the same number as the port. You can change the resource partition configuration with the cnfpart command.

Note To create additional resource partitions for a port, use the addpart command. The partition ID you use when you create the resource partition can be any number in the range from 1 to 255. After you assign a partition ID to any resource partition on the card, you must use the same partition ID for all other resource partitions on that card. Consider using 2 for the partition ID so that it matches the controller ID. If you do likewise on the other cards in your switch, there will be less confusion in managing partitions on different types of cards.

To configure a port resource partition, use the following procedure:

Step 1 Establish a configuration session using a username with Group1 privileges or higher.

Step 2 Enter the dspports command to display a list of all logical ports. Determine the port number for which you want to configure resources.

Note All port numbers appear in the ifNum (interface number) column. The partition number is the same as the interface number for automatically-added partitions.

[-dlcimin <minDlci>] [-dlcimax <maxDlci>] [-ibw <ingPctBw>] [-ebw <egrPctBw>]
Table 4-3 describes the arguments for the cnfpart command.

Table 4-3 Arguments for the cnfpart Command

Argument

Description

ifNum

Specifies the interface number (partition number) of the partition to add.

•MPSM-16-T1E1 range: 1-499

•MPSM-T3E3-155 range: 1-1003

Identifies the logical interface to which you want to add a resource partition.

Note Use the dspparts command in the Frame Relay CLI context to see all active partitions.

ctrlNum

Specifies a network controller protocol. Enter 2 to specify the PNNI controller.

Note Release 5 of the MPSM-T3E3-155 supports the PNNI controller (option 2) only. Options 1 (TAG switching) and 3 (MPLS) are not supported.

-lcn

Maximum number of connections.

•MPSM-16-T1E1 range: 0-2000

•MPSM-T3E3-155 range: 0-4000

-dlcimin

Minimum DLCI value.

•2-byte header range: 0-1023.

•4-byte header range: 0-8355840, in multiples of 32768.

For example, you can enter one of the following numbers as the minimum DLCI value, or any other number that is a multiple of 32768:
0 = (0 x 32768)
163840 = (5 x 32768)
8355840 = (255 x 32768)

Unless your provisioning plan calls for a specific range of DLCI values on a port or card, specify the minimum DLCI value as 0.

-dlcimax

Maximum DLCI value.

•2-byte header range: 0-1023.

•4-byte header range: 32767-8355840, in multiples of 32768, minus 1.

For example, you can enter one of the following numbers as the maximum DLCI value, or any other number that is a multiple of 32768 minus l:
32767 = (32768 * 1)-1
163839 = (32768 * 5)-1
6520831 = (32768 * 199)-1

Unless your provisioning plan calls for a specific range of DLCI value on a port or card, specify the maximum DLCI value as 8388607.

-ibw

Maximum ingress port bandwidth percentage for the controller type specified with the ctrlrNum argument, in the range 0-100 percent.

-ebw

Maximum egress port bandwidth percentage for the controller type specified with the ctrlrNum argument, in the range 0-100 percent.

The following example changes the maximum number of connections to 1000:
M8850_SF.9.MPSM155[FR].a > cnfpart 113 2 -lcn 1000
Step 4 Enter the dsppart <ifNum> <ctrlrNum> command to display the configuration of a particular partition. Replace <ifNum> with the interface number, and replace <ctrlrNum> with the controller number, as shown in the following example:
The following example shows the output from a dsppart command:
M8850_SF.9.MPSM155[FR].a > dsppart 113 2
  Interface Number               : 113
  Partition Id                   : pnni        Number of SPVC: 0
  Controller Id                  : 2      
  Available LCNs                 : 1000   
  Min DLCI                       : 0
  Max DLCI                       : 1023
  Ingress Percentage Bandwidth   : 100    
  Egress Percentage Bandwidth    : 100 
Selecting the Port Signaling Protocol

The default signaling protocol for new Frame Relay ports is none.

To change the signaling protocol from the default setting, perform the following steps:

Step 1 Establish a configuration session with the active PXM using a username with Group1 privileges or higher.

Step 2 Enter the dsppnports command as follows to display a list of PNNI ports available for configuration.
