Cisco Circuit Emulation Services (CESM/MPSM) Configuration Guide and Command Reference for MGX Switches, Release 5

Preparing CESM and MPSM Lines and Ports for Communications

This chapter describes how to bring up physical lines and add logical ports on the CESM-8T1/B, CESM-8T1, CESM-8E1, MPSM-8T1-CES, and MPSM-8E1-CES cards by using the command-line interface (CLI).

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

•Preparing for Provisioning

•Quickstart Provisioning Procedures

•General CESM and MPSM Provisioning Procedures

Note CESM 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 CESM and MPSM card 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 CESM 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 CESM 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, see Chapter 6, "CESM and MPSM Command Reference."

Preparing for Provisioning

Before you begin configuring lines and ports on CESM 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 CESM-8T1/B, CESM-8T1, CESM-8E1, MPSM-8T1-CES, and MPSM-8E1-CES 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 CESM 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 CESM 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.

Quickstart Provisioning Procedures

These 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 CESM 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:

•MPSM Interface and Service Configuration Quickstart

•Moving MPSM Feature Licenses Quickstart

•CESM and MPSM Line Configuration Quickstart

•CESM and MPSM Port Configuration Quickstart

These procedures provide a high-level overview and serve as a procedural reminder for users already experienced in configuring MGX switches.

MPSM Interface and Service Configuration Quickstart

To select the interface and service type on the MPSM-8T1E1 card, perform the following steps:

Moving MPSM Feature Licenses Quickstart

To move MPSM feature licenses from the MPSM-8T1E1 card into the PXM license pool, perform the following steps:

Note To install spare feature licenses into the PXM license pool, transfer feature licenses from one switch to another switch, and resolve feature license alarms, refer to the Cisco MGX 8850 (PXM1E/PXM45), Cisco MGX 8950, and Cisco MGX 8830 Configuration Guide, Release 5 and the Release Notes for Cisco MGX 8230, Cisco MGX 8250, and Cisco MGX 8850 (PXM1) Switches, Release 1.3.10.

CESM and MPSM Line Configuration Quickstart

To add a line to a CESM-8T1/B, CESM-8T1, CESM-8E1, MPSM-8T1-CES, or MPSM-8E1-CES card, perform the following steps:

CESM and MPSM Port Configuration Quickstart

Circuit emulation ports connect a Cisco MGX 8230, Cisco MGX 8250, Cisco MGX 8850 (PXM1), Cisco MGX 8850 (PXM1E/PXM45), or Cisco MGX 8830 to CPE circuit emulation devices. In most cases these devices are routers or PBXs.

Note The equipment at both ends of a circuit emulation line must be configured with compatible settings in order for the link to be logically completed.

To configure a circuit emulation port on a CESM-8T1/B, CESM-8T1, CESM-8E1, MPSM-8T1-CES, or MPSM-8E1-CES card, perform the following steps:

General CESM and MPSM Provisioning Procedures

These procedures describe preparing CESM and MPSM cards for communications:

•Selecting MPSM Interfaces and Services

•Displaying Lines

•Bringing Up Lines

•Configuring Lines

•Adding Circuit Emulation Ports

•Configuring Circuit Emulation 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.

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

M8850_SF.8.PXM.a > cnfcdmode 28 1 3

You are about to configure MPSM in slot 28 to : 

Service Type : CES 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 Circuit Emulation 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-CES or MPSM-8E1-CES.

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

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 all lines on a CESM 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 a CESM-8T1/B, CESM-8T1, CESM-8E1, MPSM-8T1-CES, or MPSM-8E1-CES card, enter the dsplns command:

PXM1E_SJ.1.6.CESM.a > dsplns

PXM1E_SJ.1.6.CESM.a > 

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 CESM and MPSM card lines.

Step 3 To display the configuration information for a particular line, enter a dspln command in the format shown below:

PXM1E_SJ.1.6.CESM.a > dspln 1

  LineNum:                   1

This sample dspln command shows the configuration parameters of a T1 line for a CESM card.

Bringing Up Lines

Installing a CESM 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 circuit emulation 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 CESM or MPSM port status light for the line is unlit, and all line alarms are cleared.

When you bring up a line on a CESM or MPSM card, the switch starts monitoring the line. The CESM 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), keep lines down until they are actually needed for communication.

To bring up a CESM-8T1/B, CESM-8T1, CESM-8E1, MPSM-8T1-CES, or MPSM-8E1-CES line on an 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 CESM 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 CESM 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 CESM or MPSM card, enter the addln command as shown below:

PXM1E_SJ.1.6.CESM.a > addln <line>

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

The following example brings up a line with the default parameters.

PXM1E_SJ.1.4.CESM.a > addln 2

PXM1E_SJ.1.4.CESM.a >

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

PXM1E_SJ.1.6.CESM.a > dsplns

  Line  Conn      Type     Status/Coding      Length     XmtClock Alarm Stats

  6.5   RJ-48 dsx1ESF         Dis/dsx1B8ZS 0-131 ft      LocalTim           

  6.6   RJ-48 dsx1ESF         Dis/dsx1B8ZS 0-131 ft      LocalTim           

  6.7   RJ-48 dsx1ESF         Dis/dsx1B8ZS 0-131 ft      LocalTim

  LineNumOfValidEntries: 8

PXM1E_SJ.1.6.CESM.a > 

When a line has been successfully brought up, the status column reports the line status as Ena, which is an abbreviation for enabled. Lines that have not been brought up are reported as Dis in the status column, which is an abbreviation for disabled.

Configuring Lines

All line types are brought up with a default configuration, which may or may not be compatible with the CPE device to which you are connecting. When configuring a CESM 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 a CESM-8T1/B, CESM-8T1, CESM-8E1, MPSM-8T1-CES, or MPSM-8E1-CES card, perform the following steps:

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

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

PXM1E_SJ.1.6.CESM.a > dsplns 

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 a dspln command in the format shown below:

M8250_SJ.1.6.MPSM8T1.CES.a > dspln 1

  LineNum:                   1

  LineConnectorType:         RJ-48

  LineType:                  dsx1ESF

  LineNumOfValidEntries: 8

M8250_SJ.1.6.MPSM8T1.CES.a > 

This sample of the dspln command shows the configuration parameters of a T1 line on an MPSM card.

Step 4 To configure a line on a CESM or MPSM card, enter a cnfln command in the format shown below:

PXM1E_SJ.1.6.CESM.a > cnfln <line_num> <line_code> <line_len> <clk_src> 
[E1-signalling|T1-Linetype]

The following example configures an E1 line for clear channel signalling.

PXM1E_SJ.1.3.CESM.a > cnfln 3 3 9 2 CLEAR

PXM1E_SJ.1.3.CESM.a >

Table 2-5 lists and describes the parameters that you use in configuring T1 and E1 lines on a CESM or MPSM card.

Step 5 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 CESM and MPSM cards. For more information on the use of this command, see Chapter 6, "CESM and MPSM Command Reference."

Adding Circuit Emulation Ports

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 circuit emulation port to a line, you enable circuit emulation communications by means of that line.

The CESM-8T1/B, CESM-8T1, CESM-8E1, MPSM-8T1-CES, and MPSM-8E1-CES, cards support structured and unstructured circuit emulation ports. Structured ports on CESM or MPSM cards can support up to 24 DS0 circuit emulation ports per T1 line and up to 31 DS0 circuit emulation ports per E1 line. Structured ports are associated with one or more consecutive timeslots on a line. Unstructured circuit emulation ports support only one port per line and must use the full bandwidth of the line for the unstructured port.

To add a circuit emulation 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 circuit emulation port. To do so, enter the dsplns command.

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 the CESM or MPSM card, enter the following command:

PXM1E_SJ.1.4.CESM.a > dspports

  Port     Ena/Speed   Type

  ------   --- ------ --------

  4.1.1    Add/1536k structur

  PortDs0UsedLine1:             0x00ffffff

  PortDs0UsedLine2:             0x00ffffff

  PortDs0UsedLine3:             0x00ffffff

  PortDs0UsedLine4:             0x00ffffff

  PortDs0UsedLine5:             0x00000000

  PortDs0UsedLine6:             0x00000000

  PortDs0UsedLine7:             0x00000000

  PortDs0UsedLine8:             0x00000000

  PortNumNextAvailable:         5

PXM1E_SJ.1.4.CESM.a >

This example shows that ports 1 through 4 have been configured on the current card and the next available port number is 5.

Step 4 To add a circuit emulation port to the card, enter the following command:

PXM1E_SJ.1.3.CESM.a > addport <port_num> <line_num> <begin_slot> <num_slot> <port_type>

The following addport command example creates an unstructured port, where all time slots are used by the port (the port range must be entered, but it is ignored).

PXM1E_SJ.1.3.CESM.a > addport 3 3 1 1 2

The next addport command example assigns half of the available T1 time slots on line 4 to port 4.

PXM1E_SJ.1.4.CESM.a > addport 4 4 1 12 1

Table 2-7 lists and describes the addport command parameters.

Step 5 To display the configuration information for a specific port, enter the following command:

PPXM1E_SJ.1.4.CESM.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 4:

PXM1E_SJ.1.4.CESM.a > dspport 4

  SlotNum:                      4

  PortLineNum:                  4

  PortNum:                      4

  PortRowStatus:                Add

  PortNumOfSlots:               12

  PortDs0ConfigBitMap(1stDS0):  0xfff(1)

  PortSpeed:                    768kbps

  PortType:                     structured

  PortState:                    Active

Configuring Circuit Emulation Ports

To modify a circuit emulation port configuration that has been added using the addport command on a CESM or MPSM card, you must first delete the port using the delport or the xcnfport command. Add the port again with the new port configuration parameters using the addport command. If there are any SPVC or PVC connections provisioned on the port, these must be deleted before you can change the port configuration.

Tip The xcnfport command may also be used to add a circuit emulation port to a line. For more information about managing ports and using these commands, refer to Chapter 5, "Managing CESM and MPSM Cards," and Chapter 6, "CESM and MPSM Command Reference".
