Release 5.1, Part Number OL-6480-01 Rev. A0, January 2005

2Preparing FRSM and MPSM Lines and Ports for Communications

This chapter describes how to bring up physical lines and add logical ports on the FRSM-8T1, FRSM-8T1-C, FRSM-8E1, FRSM-8E1-C, MPSM-8T1-FRM, MPSM-8E1-FRM, FRSM-2CT3, FRSM-2T3E3, and FRSM-HS2/B cards by using the command-line interface (CLI).

These topics describe how to bring up physical lines and add logical ports to the FRSM and MPSM cards installed in PXM45/PXM1E and PXM1 platforms:

• Preparing for Provisioning

• Quickstart Provisioning Procedures

• General FRSM and MPSM Provisioning Procedures

Note FRSM and MPSM cards, lines, and ports can also be configured using the Cisco WAN Manager (CWM) application. For configuration instructions, refer to the Cisco WAN Manager User’s Guide, Release 15.1.

Bringing up physical lines and adding logical ports on FRSM and MPSM cards is described in Table 2-1.

To eliminate redundancy and to help experienced users complete configuration tasks efficiently, this chapter provides configuration quickstart procedures.

The first time you configure a line or port, use the applicable quickstart procedure to get an overview of the tasks to be performed. Then, for more detailed instructions, consult the appropriate section(s) elsewhere in the document that are called out in the quickstart procedure. As you gain experience in configuring FRSM and MPSM lines and ports, referring to a quickstart procedure may suffice for performing a particular configuration task.

Table 2-1 Line and Port Configuration on FRSM and MPSM Cards

Configuration Task Description

Bringing up physical lines Lines establish physical layer connectivity between a FRSM/MPSM port and the same port type (T1, for example) on another device.

Adding logical ports Frame Relay ports establish Frame Relay communications over a line to Frame Relay customer premises equipment (CPE).



Chapter 2 Preparing FRSM and MPSM Lines and Ports for CommunicationsPreparing for Provisioning

Tip You can get information about most CLI commands by entering the command without parameters. Ordinarily, experienced users can configure FRSM and MPSM cards using just the quickstart procedures and the online help facilities.

Note For a detailed description of the commands used in this chapter, refer to Chapter 6, “FRSM and MPSM Command Reference.”

Preparing for ProvisioningBefore you begin configuring lines and ports on FRSM and MPSM cards, you need to initialize the cards you plan to provision. The MPSM card must be configured for the interface type and service type through the use of the PXM cnfcdmode command and also requires the management of feature licenses. Then you should develop and implement a plan for the card redundancy, line redundancy, and bulk distribution options available for each service module. This plan determines how service modules and their back cards must be installed in the chassis, and how lines must connect to the cards before software configuration starts. Without a plan developed for these services, a configuration change for any of these services has the potential to interrupt service and can require substantial configuration teardown.

The FRSM-2CT3, FRSM-2T3E3, and FRSM-HS2/B cards support 1:1 card redundancy, and the FRSM-8T1, FRSM-8T1-C, FRSM-8E1, FRSM-8E1-C, MPSM-8T1-FRM, and MPSM-8E1-FRM cards support 1:N card redundancy and bulk distribution through the support of Service Resource Module (SRM) cards. Line redundancy is available to those service modules that support bulk distribution through use of the SRME or SRME/B card with an optical back card. For an overview of the features that the SRM card provides to the FRSM and MPSM cards, see “SRM Card Services” in Chapter 1, “Introduction.”

For instructions on displaying, moving, and allocating MPSM feature licenses and managing MPSM feature license alarms, see “Managing MPSM Feature Licenses” in Chapter 5, “Managing FRSM and MPSM Cards.”

For instructions on initializing cards; configuring card redundancy, line redundancy, and bulk distribution; and managing MPSM feature licenses on the PXM processor card, refer to the Cisco MGX 8850 (PXM1E/PXM45), Cisco MGX 8950, and Cisco MGX 8830 Configuration Guide, Release 5.1, the Release Notes for Cisco MGX 8230, Cisco MGX 8250, and Cisco MGX 8850 (PXM1) Switches, Release 1.3.10, and the Cisco MGX 8850 Edge Concentrator Installation and Configuration, Release 1.1.3 documentation.

Quickstart Provisioning ProceduresThese quickstart tasks contain abbreviated procedures for selecting the MPSM interface and service type, moving MPSM feature licenses, and provisioning the line and port capabilities of FRSM and MPSM cards installed in Cisco MGX 8230, Cisco MGX 8250, Cisco MGX 8850 (PXM1), Cisco MGX 8850 (PXM1E/PXM45), and Cisco MGX 8830 switches:

Chapter 2 Preparing FRSM and MPSM Lines and Ports for CommunicationsGeneral FRSM and MPSM Provisioning Procedures

General FRSM and MPSM Provisioning ProceduresThese procedures and topics describe preparing FRSM and MPSM cards for communications:

• Selecting MPSM Interfaces and Services

• Displaying Lines

• Bringing Up Lines

• Configuring FRSM-8T1, FRSM-8T1-C, FRSM-8E1, FRSM-8E1-C, MPSM-8T1-FRM, MPSM-8E1-FRM, and FRSM-HS2/B Lines

• Configuring FRSM-2T3E3 and FRSM-2CT3 Lines

• Overview of Frame Relay Port Configuration

• Adding Frame Relay Ports

• Configuring Frame Relay Ports

Selecting MPSM Interfaces and ServicesUse the PXM cnfcdmode command as described in the following procedure to configure MPSM-8T1E1 interfaces and services:

Step 1 Establish a configuration session using a user name with SERVICE_GP privileges or higher.

Step 2 Enter the cnfcdmode command using the following format:

M8850_SF.7.PXM.a > cnfcdmode <slotNo> <ifType> <serviceType>

To use this command, the MPSM-8T1E1 card must be in the standby state with no configuration and not in a redundancy group. Table 2-2 defines the parameters for this command.

Step 2 addln <line> Prepare a FRSM or MPSM line for communications.

See the “FRSM-8T1, FRSM-8T1-C, FRSM-8E1, FRSM-8E1-C, MPSM-8T1-FRM, MPSM-8E1-FRM, and FRSM-HS2/B Line Configuration Quickstart,” or “FRSM-2T3E3 and FRSM-2CT3 Line Configuration Quickstart,” both of which appears earlier in this chapter.

Step 3 addport <options>

Related commands:dspport <port>dspportscnfport <options>xcnfport <options>

Add a Frame Relay port.

This step establishes Frame Relay communications between two Frame Relay devices.

See the “Adding Frame Relay Ports” section that appears later in this chapter.

Command Purpose




The following example shows how to configure an MPSM-8-T1E1 card to use a T1 interface and Frame Relay services:

M8850_SF.8.PXM.a > cnfcdmode 28 1 1You are about to configure MPSM in slot 28 to : Service Type : Frame Interface Type : T1cnfcdmode: Do you want to proceed (Yes/No)? y

M8850_SF.8.PXM.a >

After you set the interface type and service type, the card resets and the card state changes from Standby/Active to Active/Active.

Step 3 You can verify that the PXM cnfcdmode command has been run by looking at the Inserted Card row of the PXM dspcd <slot> command display.

Before configuring the MPSM-8-T1E1 for Frame Relay services, the Inserted Card row displays the generic name MPSM-8T1E1. After configuration, the generic name changes to a specific name such as MPSM-8T1-FRM or MPSM-8E1-FRM.

Table 2-3 lists the MPSM-8T1E1 card names and what they mean when they appear in the PXM dspcd and dspcds command displays.

The dsplns command report can be different for different card types.

The alarm state indicates whether the line is communicating with a remote switch. When the alarm state is blank or is reported as No, it indicates that the physical devices at each end of the line have established physical layer communications. Higher-layer connectivity is established later when ports are configured on the FRSM and MPSM card lines.

Step 3 To display the current configuration for all T3 or E3 lines on FRSM-2T3E3 and FRSM-2CT3 cards, enter the dspds3lns command:

Step 5 To display the current configuration for a particular line, enter the dspln command in the format shown below:

PXM1E_SJ.1.25.FRSM.a > dspln 2

LineNum: 2 LineConnectorType: RJ-48 LineType: dsx1ESF LineEnable: Enabled LineCoding: dsx1B8ZS LineLength: 0-131 ft LineXmtClockSource: LocalTiming LineLoopbackCommand: NoLoop LineSendCode: NoCode LineUsedTimeslotsBitMap: 0x400 LineLoopbackCodeDetection: codeDetectDisabled LineBertEnable: Disable


This sample dspln command shows the configuration parameters of a T1 line for a FRSM-8T1-C card.

Bringing Up LinesInstalling a FRSM or MPSM card can add up to 8 physical lines to your switch. You must bring up a line before you can configure it or before you can provision Frame Relay services on the line.

Before a line is brought up, or after it is brought down, the switch does not monitor the line. Prior to bringing up a line, the FRSM or MPSM port status light for the line is unlit, and all line alarms are cleared.

When you bring up a line on a FRSM or MPSM card, the switch starts monitoring the line. The FRSM or MPSM card port status light turns green when physical layer connectivity is established with a remote device. If a physical layer communications problem occurs, the port status light turns red and an alarm is reported.

Tip To minimize the number of alarms reported and to reduce the frequency of failed port status lamps (which display red), it is recommended that you keep lines down until they are actually needed for communication.




To bring up a FRSM-8T1, FRSM-8T1-C, FRSM-8E1, FRSM-8E1-C, FRSM-2T3E3, FRSM-2CT3, FRSM-HS2/B, MPSM-8T1-FRM, or MPSM-8E1-FRM line on a Cisco MGX switch, perform the following steps:


Step 2 Select the FRSM or MPSM card on which you want to bring up a line by issuing the cc command, as shown below:

PXM1E_SJ.1.7.PXM.a > cc <slotnumber>

Replace the <slotnumber> parameter with the number of the slot in which the FRSM card is installed.

Step 3 Enter the dsplns command to check which lines on the card are available to bring up.

Step 4 To activate a line on the FRSM or MPSM card, enter the addln command as shown below:

PXM1E_SJ.1.1.FRSM.a > addln <line> [<interface_type>]

Replace the <line> parameter with the number corresponding to the back card port to which the line is connected. Table 2-4 lists the valid line numbers for the FRSM and MPSM cards.

The optional <interface_type> parameter applies only when you are using the FRSM-HS2/B card with the 12IN1-8S back card. The default interface type for the 12IN1-8S back card is V.35. To specify the interface type as X.21, replace the <interface_type> with a value of 2.

Table 2-4 FRSM and MPSM Card Types

Front Card Valid Line Numbers

FRSM-8T1 1 to 8

FRSM-8T1-C 1 to 8

FRSM-8E1 1 to 8

FRSM-8E1-C 1 to 8

MPSM-8T1-FRM 1 to 8

MPSM-8E1-FRM 1 to 8

FRSM-2CT3 1 to 2

FRSM-2T3E3 1 to 2

FRSM-HS2/B 1 to 2 with HSSI 1 to 8 with 12IN1-8S




Step 5 Enter the dsplns command to verify that the line has been successfully brought up.


Line Conn Type Status/Coding Length XmtClock Alarm Stats Type Source Alarm ---- ----- ------------ ------ -------- ------------- -------- ----- ----- 1.1 RJ-48 dsx1ESF Ena/dsx1B8ZS 0-131 ft LocalTim Yes No 1.2 RJ-48 dsx1ESF Ena/dsx1B8ZS 0-131 ft LocalTim Yes No 1.3 RJ-48 dsx1ESF Ena/dsx1B8ZS 0-131 ft LocalTim Yes No 1.4 RJ-48 dsx1ESF Dis/dsx1B8ZS 0-131 ft LocalTim 1.5 RJ-48 dsx1ESF Dis/dsx1B8ZS 0-131 ft LocalTim 1.6 RJ-48 dsx1ESF Dis/dsx1B8ZS 0-131 ft LocalTim 1.7 RJ-48 dsx1ESF Dis/dsx1B8ZS 0-131 ft LocalTim 1.8 RJ-48 dsx1ESF Dis/dsx1B8ZS 0-131 ft LocalTim


When a line has been successfully brought up, the status column reports the line status as Enable or Ena. Lines that have not been brought up are reported as Disable or Dis in the status column.

Configuring FRSM-8T1, FRSM-8T1-C, FRSM-8E1, FRSM-8E1-C, MPSM-8T1-FRM, MPSM-8E1-FRM, and FRSM-HS2/B Lines

All line types are brought up with a default configuration, which may or may not be compatible with the Frame Relay device to which you are connecting. When configuring a FRSM or MPSM card line, you must ensure that the devices at both ends of the connection are using the same configuration parameters on the shared line.

To configure lines on FRSM-8T1, FRSM-8T1-C, FRSM-8E1, FRSM-8E1-C, MPSM-8T1-FRM, MPSM-8E1-FRM, and FRSM-HS2/B cards, perform the following steps:


Step 2 If you do not know the line number you want to configure on the FRSM or MPSM card, enter the dsplns command to display the current configuration of all lines on the card:


Remember, you cannot configure a line until you have brought it up. See the “Bringing Up Lines” section.




Step 3 To display the configuration information for the particular line that you want to configure, enter the dspln command in the format shown below:

PXM1E_SJ.1.11.VHSHS2B.a > dspln 1

LineNum: 1 LineEnable: Modify LineType: DCE LineRate: 8192000 bps LineLoopbackCommand: v35Metallic LineSendCode: NoCode LineLoopbackCodeDetection: codeDetectEnabled LineClockType: nonInvertedAndNotLooped LineInterfaceType: X.21 DTEClkFrequencyThreshold: 3 LineRateVariaton: 0 ppm


This sample dspln command shows the configuration parameters of a line on a FRSM-HS2/B card.

Step 4 To configure a line on a FRSM-8T1, FRSM-8T1-C, FRSM-8E1, FRSM-8E1-C, MPSM-8T1-FRM, or MPSM-8E1-FRM card, enter a cnfln command in the format shown below:

PXM1E_SJ.1.25.FRSM.a > cnfln <line_num> <line_code> <line_len> <clk_src> [E1-signalling|T1-Linetype]

Table 2-5 lists and describes the parameters that you use in configuring T1 and E1 lines on a FRSM-8T1, FRSM-8T1-C, FRSM-8E1, FRSM-8E1-C, MPSM-8T1-FRM, or MPSM-8E1-FRM card.

Table 2-5 Line Parameters for cnfln Command (continued)





Step 6 To verify the line configuration changes made above, enter the dspln command for the appropriate line.

When configuring E1 signalling methods using the cnfln command, Table 2-6 shows the corresponding El line type displayed in the output of the dspln and dsplns commands.

Note The xcnfln command may also be used to configure lines on the FRSM-8T1, FRSM-8T1-C, FRSM-8E1, FRSM-8E1-C, MPSM-8T1-FRM, MPSM-8E1-FRM, and FRSM-HS2/B cards. For more information on the use of this command, see Chapter 6, “FRSM and MPSM Command Reference.”

Configuring FRSM-2T3E3 and FRSM-2CT3 LinesAll line types are brought up with a default configuration, which may or may not be compatible with the Frame Relay device to which you are connecting. When configuring a FRSM card line, you must ensure that the devices at both ends of the connection are using the same configuration parameters on the shared line.

When configuring FRSM-2CT3 lines, in addition to the two channelized DS3 lines, 56 channelized DS1 lines may be configured.

To configure lines on FRSM-2T3E3 and FRSM-2CT3 cards, perform the following steps:


Step 2 If you do not know the line number you want to configure on the FRSM card, enter the dspds3lns command to display the current configuration of all lines on the card:

PXM1E_SJ.1.20.VHS2E3.a > dspds3lns

-intrtyp This option selects the interface type when the MGX-12IN1-8S back card is used with the FRSM-HS2/B card. Select from the following options:

• X.21 = 2

• V.35 = 3 (default)

Step 6 To verify the line configuration changes made above, enter the dspds3ln or dspln command for the appropriate line.

Note The xcnfln command may also be used to configure lines on FRSM-2T3E3 and FRSM-2CT3 cards. For more information on the use of this command, see Chapter 6, “FRSM and MPSM Command Reference.”

Overview of Frame Relay Port ConfigurationThe “Bringing Up Lines” section that appears earlier in this chapter describes how to bring up physical lines by specifying the correct line port number. Line ports correspond to the line connectors on the back cards of Cisco MGX 8230, Cisco MGX 8250, Cisco MGX 8850 (PXM1), Cisco MGX 8850 (PXM1E/PXM45), or Cisco MGX 8830 switches.

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

Regardless of the card type or physical characteristics of a port (speed, timeslots, and so on), each port can be configured as the following:

• Frame Relay port. 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 a single Frame Relay port and are differentiated by their data-link connection identifiers (DLCIs).

• Frame-based user-network interface (FUNI) ports. This is a port that sends and receives standard FUNI frames. Based on the three modes of ATM DXI, FUNI was developed to provide an ATM UNI in a frame format similar to Frame Relay frames. FUNI frames use the SAR functionality found in the ATM network and does not use the interworking function (IWF) for mapping and encapsulation functions. Like a Frame Relay port, a FUNI port supports SVCs, fractional T1s, multiple virtual circuits (VCs) terminating on a single Frame Relay port and are differentiated by their data-link connection identifiers (DLCIs). Unlike ATM DXI, an ATM CSU/DSU is not required.

line_len Length of line.

• 1 = less than 225 feet

• 2 = greater than 225 feet

clk_src DSX3 clock source.

• 1 = backplane clock (2E3 only)

• 2 = recovery clock (2T3 and 2E3 only)

• 3 = local clock (2CT3, 2T3, and 2E3)

Table 2-7 Line Parameters for cnfds3ln Command (continued)





• Frame Forwarding port. 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. Application examples include routers interconnected by means of 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 a single 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.

– A single 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.

The FRSM-8T1-C, FRSM-8E1-C, MPSM-8T1-FRM, and MPSM-8E1-FRM cards support channelized T1 or E1 Frame Relay ports. The channelized 8-port FRSM or MPSM cards can support up to 24 DS0 Frame Relay ports per T1 line and up to 31 DS0 Frame Relay ports per E1 line. At the customer premises site, a Frame Relay Access Device (FRAD) is attached to a time-division multiplexer (TDM) that aggregates multiple subrate traffic streams onto a single T1 or E1 line. Channelized ports are associated with one or more consecutive timeslots on the line.

The FRSM-2CT3 card supports both channelized DS3 lines and channelized DS1 lines. Each channelized DS3 line supports 28 channelized DS1 lines providing a total of 56 channelized DS1 lines per card. Although each channelized DS1 line can support up to 24 DS0 Frame Relay ports per T1 line, the maximum amount of Frame Relay ports that can be configured per FRSM-2CT3 card is 256 logical ports.

The FRSM-8T1 and FRSM-8E1 cards support fractional Frame Relay ports. On a fractional (unchannelized) FRSM, each line can support only a single port. The end-user equipment either uses the entire bandwidth of the T1 or E1 interface, or uses multiple timeslots on the T1 or E1 line. Like channelized Frame Relay ports, fractional ports are defined by consecutive timeslots on the line.

The FRSM-HS2/B card supports serial Frame Relay ports. A serial port is associated with a single line, and its speed is defined by the line rate. Although a T3 or E3 line is not strictly serial, the FRSM-2T3E3 card supports port provisioning like other serial ports.

Adding Frame Relay PortsTo add a Frame Relay port to a line, perform the following steps:

Step 1 Establish a configuration session using a user name with GROUP1 privileges or higher.

Step 2 Determine the line number on which you intend to add the Frame Relay port. To do so, enter the dsplns command for FRSM-8T1, FRSM-8T1-C, FRSM-8E1, FRSM-8E1-C, MPSM-8T1-FRM, MPSM-8E1-FRM, FRSM-2CT3, and FRSM-HS2/B cards, or enter the dspds3lns command for FRSM-2T3E3 cards.




Step 3 Verify that the port number you want to use is not already in use. To display a list of the configured ports on a FRSM or MPSM card, enter the following command:

PXM1E_SJ.1.30.FRSM.a > dspports

Port Ena/Speed EQServ SignalType T391 T392 N391 N392 N393 Type Alarm ELMI Ratio -------- --- ----- ------ ------------ ---- ---- ---- ---- ---- -------- ----- ---- 30.1.1 Add/1536k 1 NoSignalling 10 15 6 3 4 frameRel No Off 30.2.2 Add/1536k 1 NoSignalling 10 15 6 3 4 frameRel No Off 30.7.7 Add/1536k 1 NoSignalling 10 15 6 3 4 frameRel No Off 30.8.8 Add/1536k 1 NoSignalling 10 15 6 3 4 frameRel Yes Off

This example shows the command display for a FRSM-8T1-C card. This command displays all the port numbers configured on the FRSM card in the Port column. The port numbers in the Port column appear in the format slot.line.port, so the port number is the number that appears after the last period. When you add a port, you must specify a unique port number. For example, if port number 2 is assigned to line 2, you cannot use port 2 on any other line on that FRSM card.

Note The MPSM-8T1-FRM, MPSM-8E1-FRM, FRSM-8T1-C, FRSM-8E1-C, and FRSM-2CT3 cards support multiple ports on the same line. You can add just one port per line for the FRSM-8T1, FRSM-8E1, FRSM-2T3E3, and FRSM-HS2/B cards.

Step 4 To add a Frame Relay port to a FRSM-8T1, FRSM-8T1-C, FRSM-8E1, FRSM-8E1-C, or FRSM-2CT3 card, enter the following command:

PXM1E_SJ.1.30.FRSM.a > addport <port_num> <line_num> <ds0_speed> <begin_slot> <num_slot> <port_type> [lmi_autosense]

Table 2-8 lists and describes the addport command parameters.

Step 5 To add a Frame Relay port to an MPSM-8T1-FRM or MPSM-8E1-FRM card, enter the following command:

PXM1E_SJ.1.30.MPSM8T1.FRM.a > addport <port_num> <line_num> <ds0_speed> <begin_slot> <num_slot> <port_type> [lmi_autosense]

LMI autosense on the MPSM-8T1-FRM or MPSM-8E1-FRM cards applies to Release 5.1 and above.


Step 6 To add a Frame Relay port to a FRSM-2T3E3 or FRSM-HS2/B card, enter the following command:

PXM1E_SJ.1.30.FRSM.a > addport <port_num> <line_num> <port_type> [lmi_autosense]





Table 2-8 Parameters for the addport Command

Parameter or Option Description

port_num Port number for the Frame Relay service. The port number range varies with the card type:

• FRSM-8T1, FRSM-8T1-C, MPSM-8T1-FRM range: 1–192

• FRSM-8E1, FRSM-8E1-C, MPSM-8E1-FRM range: 1–248

• FRSM-2T3E3 range: 1–2

• FRSM-HS2/B range: 1–8 with 12IN1-8S back card

Tip Since the non-channelized FRSM-8T1 and FRSM-8E1 cards support only one port per line, you might want to limit the port numbers to 1-8 for easier identification.

Note On the FRSM-2CT3, FREEDM chip resources are distributed across the two DS3 lines. Use the dspfdminfo command to monitor the allocation of these resources when adding ports to the channelized DS1 lines.

line_num Line number to which the port definition applies. To display the lines that have been added, enter the dsplns or dspds3lns command. You cannot add a port to a line unless the Status/Coding column shows that the line is enabled (Ena). The line number range varies with the card type:

• FRSM-8T1, FRSM-8T1-C, MPSM-8T1-FRM range: 1–8

• FRSM-8E1, FRSM-8E1-C, MPSM-8E1-FRM range: 1–8

• FRSM-2T3E3 range: 1–2

• FRSM-2CT3 range: 1-56 (Channelized T1s)

• FRSM-HS2/B range: 1–2 with HSSI back card

• FRSM-HS2/B range: 1–8 with 12IN1-8S back card

ds0_speed This option applies only to FRSM-8T1, FRSM-8T1-C, FRSM-8E1, FRSM-8E1-C, MPSM-8T1-FRM, MPSM-8E1-FRM, and FRSM-2CT3 (channelized T1) ports and sets the bit rate as either 56 Kbps or 64 Kbps for the DS0:

• 1 = 56 Kbps

• 2 = 64 Kbps

Note When adding a port to an E1 line configured with CLEAR signalling, use only the 64 Kbps option.




begin_slot This option applies only to FRSM-8T1, FRSM-8T1-C, FRSM-8E1, FRSM-8E1-C, MPSM-8T1-FRM, MPSM-8E1-FRM and FRSM-2CT3 (channelized T1) ports and selects the starting DS0 time slot for port communications within the T1 or E1 frame. Valid time slot numbers are:

• FRSM-8T1, FRSM-8T1-C, MPSM-8T1-FRM, FRSM-2CT3 range: 1–24

• FRSM-8E1, FRSM-8E1-C, MPSM-8E1-FRM range:

– With CAS line signalling: 2–16, 18-32 (Slot 1 is reserved for framing and slot 17 is reserved for signalling)

– With CCS line signalling: 2–32 (Slot 1 is reserved for framing)

– With CLEAR line signalling: 1

Tip The non-channelized FRSM-8T1 and FRSM-8E1 cards support fractional frame relay ports and only one port per line. If you want to use the full bandwidth of the line, you should enter 1 (for the FRSM-8T1 or FRSM-8E1 with CLEAR signalling) or 2 (for the FRSM-8E1 with CAS or CCS signalling) for the starting time slot.

num_slot This option applies only to FRSM-8T1, FRSM-8T1-C, FRSM-8E1, FRSM-8E1-C, MPSM-8T1-FRM, MPSM-8E1-FRM, and FRSM-2CT3 (channelized T1) ports and determines the number of consecutive DS0 time slots for this port within the T1 or E1 frame. Valid time slot numbers are:

• FRSM-8T1, FRSM-8T1-C, MPSM-8T1-FRM, FRSM-2CT3 range: 1–24

• FRSM-8E1, FRSM-8E1-C, MPSM-8E1-FRM range:

– With CAS line signalling: 1-30

– With CCS line signalling: 1-31

– With CLEAR line signalling: 32

Tip The non-channelized FRSM-8T1 and FRSM-8E1 cards support only one port per line. If you want to use the full bandwidth of the line, you should enter the maximum time slot number (either 24, 30, 31, or 32). (E1 lines with CLEAR line signalling support only the full 32 time slots.)

port_type Type of service as Frame Relay, FUNI, or frame forwarding.

• 1 = Frame Relay UNI or NNI

• 2 = ATM Forum FUNI mode 1A (AAL5 only)

• 3 = Frame forwarding (no translation or mapping of header contents, CRC evaluated)

Table 2-8 Parameters for the addport Command (continued)





The following addport command example defines Frame Relay port 1 on T1 line 1 in slot 11 with LMI autosense. Because this is a non-channelized card, slots 1 through 24 are assigned to this port.

PXM1E_SF.1.11.FRSM.a > addport 1 1 1 1 24 1 2

The next addport command example defines Frame Relay port 1 on the channelized T1 line 1 in slot 30 with LMI autosense. Slots 1 through 4 are assigned to port 1.

PXM1E_SJ.1.30.FRSM.a > addport 1 1 1 1 4 1 2

Step 7 To display the configuration information for a specific port, enter the following command:

PXM1E_SJ.1.25.FRSM.a > dspport <port>

Replace the <port> parameter with the number assigned to the port during configuration.

The following example shows the output of a dspport command for port number 8:

PXM1E_SJ.1.25.FRSM.a > dspport 8

lmi_autosense LMI autosense. With LMI autosense enabled the frame relay port will detect and configure its LMI signalling type to that of the LMI signalling type configured on the attached CPE. If LMI autosense is set to manual, the user must configure the LMI signalling type by using the cnfport or xcnfport commands.

• 1 = Manual (default)

• 2 = AutoSense

Note LMI autosense is supported only on UNI frame relay connections, and the range of DLCIs supported is 16-991.

Note LMI autosense is supported on MPSM-8T1-FRM and MPSM-8E1-FRM cards in switches running Release 5.1 or higher.

Tip To delete the port configuration, enter the delport command. For more information about this command, refer to Chapter 5, “Managing FRSM and MPSM Cards,” and Chapter 6, “FRSM and MPSM Command Reference”.

Configuring Frame Relay PortsWhen Frame Relay ports are added some of the port parameters are in a default configuration which may or may not be compatible with the Frame Relay device to which you are connecting. When configuring a Frame Relay port, you must ensure that the devices at both ends of the connection are using the same port configuration parameters in order for communications to be successful.

When configuring a Frame Relay port the cnfport command is used. Configuring the LMI signalling type can either be done manually, or by use of the LMI autosense option. With LMI autosense enabled the frame relay port will detect and configure its LMI signalling type to that of the LMI signalling type configured on the attached CPE.





To configure Frame Relay ports on FRSM and MPSM cards, perform the following steps:

Step 1 Establish a configuration session using a user name with GROUP1 privileges or higher.

Step 2 If you do not know the port number you want to configure on the FRSM or MPSM card, enter the dspports command to display a list of the currently configured ports:

M8850_SF.1.12.FRSM.a > dspports

This example shows the output of the dspports command on a FRSM-8T1-C card. This command displays all the port numbers configured on the FRSM card in the Port column. The port numbers in the Port column appear in the format slot.line.port, so the port number is the number that appears after the last period.

Step 3 To display the configuration information for the particular port that you want to configure, enter the following command:

PXM1E_SJ.1.25.FRSM.a > dspport <port>

The following example shows the output of a dspport command for port number 1:

LMI autosense is supported on MPSM-8T1-FRM and MPSM-8E1-FRM cards in switches running Release 5.1 or higher.

Table 2-9 lists and describes the cnfport command parameters.

Table 2-9 Parameters for the cnfport Command


port Num Specify the number for the port you want to configure. The dspports command lists all configured ports.

lmiSig LMI signaling protocol type.

• None = N (default)

• Strata LMI = S

• Annex A UNI = au

• Annex D UNI = du

• Annex A NNI = an

• Annex D NNI = dn

Note When LMI is configured, the maximum number of connections per port for Strata LMI port is 560 and for Annex A/D UNI/NNI port is 898.




asyn 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. An Update Status (UPD) message indicates the PVC status and the Multicast status of a single DLCI on a port. UPD messages are precipitated by changes in the configuration, active status, or flow control of a PVC. An Unsolicited Full Status (UFS) message indicates the status of all PVCs or Multicast groups on a port.

• Update Status (UPD) and Unsolicited Full Status (UFS) disabled = n or 1 (default)

• UPD enabled = y or 2

• UFS enabled = 3 (Supported only with NNI signaling)

• UPD and UFS enabled = 4 (Supported only with NNI signaling)

Note Asynchronous updates are not part of the periodic polling process and do not satisfy the requirement for a status message in a given polling interval.

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 FRSM or 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.

• Disable = n or N (default)

• Enable = y or Y

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 bi-directional polling is present.

Range: 5–30 sec

Default: 10

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 bi-directional polling is present.

Range: 5–30 sec

Default: 15

Table 2-9 Parameters for the cnfport Command (continued)





The following cnfport command example configures Frame Relay port 3 with Annex A UNI signaling, enables UPD asynchronous updates, enables Enhanced LMI, and keeps the default settings for the timers and counters:

PXM1E_SJ.1.11.VHSHS2B.a > cnfport 3 au 2 y 10 15 6 3 4

Note The xcnfport command may also be used to modify a Frame Relay port on a line. For more information about using this command, refer to Chapter 6, “FRSM and MPSM Command Reference.”

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 bi-directional polling is present.

Range: 1–255

Default: 6

N392 N392 counter. This setting specifies the 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: 1–10

Default: 3

N393 N393 counter. This setting is the monitored 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).

Range: 1–10

Default = 4

lmi_autosense LMI autosense. With LMI autosense enabled the frame relay port will detect and configure its LMI signaling type to that of the LMI signaling type configured on the attached CPE. If LMI autosense is set to manual, the user must configure the LMI signaling type by using the lmiSig option above or use the addport or xcnfport commands.

• 1 = Manual (default)

• 2 = AutoSense

Note LMI autosense is supported only on UNI frame relay connections, and the range of DLCIs supported is 16-991.
