•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.

---

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

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).

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.

---

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.

Preparing for Provisioning

Before 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 "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, 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.

•Configuring Frame Relay Ports

Selecting MPSM Interfaces and Services

Use 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.

Table 2-2 cnfcdmode Command Parameters

Parameter	Description
slotNo	Enter the number for the slot in which the MPSM-8T1E1 card is installed.
ifType	Enter a number from the following list that selects the interface type to be used with the MPSM-8T1E1: •T1 Interface = 1 •E1 Interface = 2 •T3 Interface = 3 (Not applicable to the MPSM-8T1E1) •E3 Interface = 4 (Not applicable to the MPSM-8T1E1)
serviceType	Enter a number from the following list that selects the service the MPSM-8T1E1 will support: •Frame Relay Service = 1 •ATM Service = 2 •CES Service = 3

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 1

You are about to configure MPSM in slot 28 to : 

Service Type : Frame Interface Type : T1

cnfcdmode: 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.

Table 2-3 MPSM-8-T1E1 Card Names in the PXM dspcd and dspcds Command Displays

Card Name	Description
MPSM-8T1E1	No service configured on card.
MPSM-8T1-ATM	Configured for ATM services and T1 interfaces.
MPSM-8E1-ATM	Configured for ATM services and E1 interfaces.
MPSM-8T1-CES	Configured for Circuit Emulation services and T1 interfaces.
MPSM-8E1-CES	Configured for Circuit Emulation services and E1 interfaces.
MPSM-8T1-FRM	Configured for Frame Relay services and T1 interfaces.
MPSM-8E1-FRM	Configured for Frame Relay services and E1 interfaces.

For more information on use of the PXM cnfcdmode command, refer to the Cisco MGX 8850 (PXM1E/PXM45), Cisco MGX 8950, and Cisco MGX 8830 Configuration Guide, Release 5, the Cisco MGX 8850 (PXM45/PXM1E), Cisco MGX 8950, and Cisco MGX 8830 Command Reference Guide, Release 5, 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.

Displaying Lines

To display the current configuration of lines on a FRSM or MPSM card, perform the following steps:

---

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

Step 2 To display the current configuration for all lines on FRSM-8T1, FRSM-8T1-C, FRSM-8E1, FRSM-8E1-C, MPSM-8T1-FRM, MPSM-8E1-FRM, and FRSM-HS2/B cards, enter the dsplns command:

  LineNumOfValidEntries: 8

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:

PXM1E_SJ.1.20.VHS2E3.a > dspds3lns

  Line  Type   Status/Coding    Length    XmtClock   Alarm  Stats

Bringing Up Lines

Installing 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 1 Establish a configuration session using a user name with GROUP 1 privileges or higher.

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

Overview of Frame Relay Port Configuration

The "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.

•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 Ports

To 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

  PortDs0UsedLine8:             0x00ffffff

  PortNumNextAvailable:         3

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>

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

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 lists and describes the addport command parameters.

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-2CT3 range: 1-256 (Channelized T1s) •FRSM-HS2/B range: 1-2 with HSSI back card •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:
