Configuring the PA-MC-8TE1+


To continue your PA-MC-8TE1+ port adapter installation, you must configure the card type as either T1 or E1 and then configure the interfaces. The instructions that follow apply to all supported platforms. Minor differences between the platforms—with Cisco IOS software commands—are noted.

This chapter contains the following sections:

Using the EXEC Command Interpreter

Configuring the Interfaces

Checking the Configuration


Note For complete information on configuring the supervisor engine and all modules on the Catalyst 6500 series switches and Cisco 7600 series Internet Routers, refer to the publications listed in the "Related Documentation" section on page viii. For information on all Catalyst 6500 series switches and Cisco 7600 series Internet Router commands, refer to the publications listed in the "Related Documentation" section on page viii.


Using the EXEC Command Interpreter

You modify the configuration of your router through the software command interpreter called the EXEC (also called enable mode). You must enter the privileged level of the EXEC command interpreter with the enable command before you can use the configure command to configure a new interface or change the existing configuration of an interface. The system prompts you for a password if one has been set.

The system prompt for the privileged level ends with a pound sign (#) instead of an angle bracket (>). At the console terminal, use the following procedure to enter the privileged level:


Step 1 At the user-level EXEC prompt, enter the enable command. The EXEC prompts you for a privileged-level password as follows:

Router> enable 

Password: 

Step 2 Enter the password (the password is case sensitive). For security purposes, the password is not displayed.

When you enter the correct password, the system displays the privileged-level system prompt (#):

Router#


To configure the new interfaces, proceed to the "Configuring the Interfaces" section.

Configuring the Interfaces

The PA-MC-8TE1+ interfaces can be configured as E1 or T1 interfaces. After you verify that the new PA-MC-8TE1+ is installed correctly (the enabled LED goes on), use the privileged-level configure command to configure the new interfaces. Have the following information available:

Protocols you plan to route on each new interface

IP addresses, if you plan to configure the interfaces for IP routing

Clock timing source you plan to use for each new interface and clock speeds for external timing

If you installed a new PA-MC-8TE1+ or if you want to change the configuration of an existing interface, you must enter configuration mode to configure the new interfaces. If you replaced a PA-MC-8TE1+ that was previously configured, the system recognizes the new interfaces and brings each of them up in their existing configurations.

For a summary of the configuration options available and instructions for configuring interfaces on a PA-MC-8TE1+, refer to the appropriate configuration publications listed in the "Related Documentation" section on page viii.

You execute configuration commands from the privileged level of the EXEC command interpreter, which usually requires password access. Contact your system administrator, if necessary, to obtain password access. (See the "Using the EXEC Command Interpreter" section for an explanation of the privileged level of the EXEC.)

This section contains the following subsections:

Shutting Down an Interface

Before you remove an interface that you will not replace, or replace port adapters, use the shutdown command to shut down (disable) the interfaces to prevent anomalies when you reinstall the new or reconfigured port adapter. When you shut down an interface, it is designated administratively down in the show command displays.

Follow these steps to shut down an interface:


Step 1 Enter the privileged level of the EXEC command interpreter (also called enable mode). (See the "Using the EXEC Command Interpreter" section for instructions.)

Step 2 At the privileged-level prompt, enter configuration mode and specify that the console terminal is the source of the configuration subcommands, as follows:

Router# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#

Step 3 Shut down interfaces by entering the interface subcommand (followed by the interface type and the interface address), and then enter the shutdown command. See the "Using the show interfaces Command" section for the command syntax.

When you have finished, press Ctrl-Z—hold down the Control key while you press Z—or enter end or exit to exit configuration mode and return to the EXEC command interpreter.


Note If you need to shut down additional interfaces, enter the interface subcommand (followed by the interface address of the interface) for each of the interfaces on your port adapter. Use the no shutdown command to enable the interface.


Step 4 Write the new configuration to NVRAM as follows:

Router# copy running-config startup-config
[OK]
Router#

The system displays an OK message when the configuration has been stored in NVRAM.

Step 5 Verify that new interfaces are now in the correct state (shut down) using the show interfaces command (followed by the interface type and interface address of the interface) to display the specific interface. The "Using the show interfaces Command" section provides examples.

Step 6 Re-enable interfaces by doing the following:

a. Repeat Step 3 to re-enable an interface. Substitute the no shutdown command for the shutdown command.

b. Repeat Step 4 to write the new configuration to memory. Use the copy running-config startup-config command.

c. Repeat Step 5 to verify that the interfaces are in the correct state. Use the show interfaces command followed by the interface type and interface address of the interface.


For complete descriptions of software configuration commands, refer to the publications listed in the "Related Documentation" section on page viii.

Performing a Basic Interface Configuration

Following are instructions for a basic configuration, which include specifying card and service type, enabling an interface, and specifying IP routing. You might also need to enter other configuration subcommands, depending on the requirements for your system configuration and the protocols you plan to route on the interface. For complete descriptions of configuration subcommands and the configuration options available for serial interfaces, refer to the appropriate software documentation.


Note Because the PA-MC-8TE1+ port adapter can be configured for E1 or T1 connectivity, you must specify the card type as E1 or T1, as described in the following procedure. There is no default card type. The port adapter is not functional until the card type is set. Information about the port adapter is not indicated in the output of any show commands unless the card type has been set to E1 or T1.


In the following procedure, press the Return key after each step unless otherwise noted. At any time you can exit the privileged level and return to the user level by entering disable at the prompt as follows:

Router# disable

Router> 

Step 1 Enter configuration mode and specify that the console terminal is the source of the configuration subcommands, as follows:

Router# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#

Step 2 Specify whether the card is to be used as T1 or E1 by using the card type command in configuration mode.

The example below sets the card in slot 1 to T1:

Router(config)# card type t1 1

The example below sets the card in slot 1 to E1:

Router(config)# card type e1 1


Note To change the card type of the PA-MC-8TE1+ after the card type command has been entered, you must remove the card from the router, save the running configuration to NVRAM, and reboot the router. When the router has finished rebooting, reinsert the card and repeat Step 2

Or you can save the running configuration to the TFTP server and edit the card type in the saved file. Then use the copy tftp://tftp address/file name system://startup-config command to copy the configuration back to the router, and then reload.


Step 3 Specify the first interface to configure by entering the interface command, followed by the type of interface and the interface address you plan to configure. The "Using the show interfaces Command" section provides examples.

Step 4 Assign an IP address and subnet mask to the interface (if IP routing is enabled on the system) by using the ip address subcommand, as in the following example:

Router(config-if)# ip address 10.0.0.0 10.255.255.255

Step 5 Add any additional configuration subcommands required to enable routing protocols and set the interface characteristics.

Step 6 Re-enable the interfaces using the no shutdown command. (See the "Shutting Down an Interface" section.)

Step 7 Configure all additional port adapter interfaces as required.

Step 8 After including all of the configuration subcommands to complete your configuration, press Ctrl-Z—hold down the Control key while you press Z—or enter end or exit to exit configuration mode and return to the EXEC command interpreter prompt.

Step 9 Write the new configuration to NVRAM as follows:

Router# copy running-config startup-config
[OK]
Router#

This completes the procedure for creating a basic configuration.

Configuring the Controller

Following are instructions for a basic controller configuration for the PA-MC-8TE1+:


Step 1 Enter configuration mode and specify that the console terminal is the source of the configuration subcommands, as follows:

Router# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#

Step 2 Choose a controller by entering the controller t1 or controller e1 subcommand, followed by the interface address of the interface you plan to configure.

Step 3 In controller configuration mode, enter the framing [sf | esf] configuration subcommand to set the framing format for T1, as in the following example:

Router(config-controller)# framing esf

Enter the framing crc4 configuration subcommand to set the framing format for E1, as in the following example:

Router(config-controller)# framing crc4

Step 4 Enter the linecode b8zs subcommand to select the line coding for T1:

Router(config-controller)# linecode b8zs

Enter the linecode hdb3 subcommand to select the line coding for E1:

Router(config-controller)# linecode hdb3

Step 5 Enter the clock source {internal | line} configuration subcommand to set the clock source, as in the following example:

Router(config-controller)# clock source internal

Use the no form of this command to restore the default, which is line.

Step 6 Enter the channel-group number timeslots value {speed [56 | 64]} configuration subcommand to set the channel group, as in the following example:

Router(config-controller)# channel-group 0 timeslots 12 speed 64


Note The channel-group number can be from 0 to 23 and the time slot value can be from 1 to 24 for T1. The channel-group number can be from 0 to 30 and the time slot value can be from 1 to 31 for E1. The maximum number of channel groups per each 8-port PA-MC-8TE1+ is 256.


Step 7 Enter the pri-group timeslots range configuration subcommand to set the PRI group, as in the following example:

Router(config-controller)# pri-group timeslots 12


Note The channel-group number can be from 0 to 23 and the time slot value can be from 1 to 24 for T1. The channel-group number can be from 0 to 30 and the time slot value can be from 1 to 31 for E1.


Step 8 Enter the description line (up to 80 characters describing this controller) configuration subcommand to set the description, as in the following example:

Router(config-controller)# description Arizona 3 Router; location: building 2

Step 9 Enter the cablelength {long [gain26 | gain36] [0db | -7.5db  | -15db | -22.5db]} configuration subcommand to set the cable length, as in the following example:

Router(config-controller)# cablelength long gain26 -15db

Enter the no form of this command to restore the default, which is gain36, 0dB.

Step 10 For T1 enter the fdl {att | ansi} configuration subcommand to set the Facility Data Link (FDL), as in the following example:

Router(config-controller)# fdl ansi

Use the no form of this command to disable FDL.


Note The fdl configuration subcommand is not allowed in Super Frame mode.


Step 11 Enter the shutdown configuration subcommand to shut down the controller, as in the following example:

Router(config-controller)# shutdown


To exit controller configuration mode and return to global configuration mode, enter the exit command. To exit configuration mode and return to privileged EXEC mode, use the end command or press Ctrl-Z.

Configuring Cyclic Redundancy Checks

Cyclic redundancy check (CRC) is an error-checking technique that uses a calculated numeric value to detect errors in transmitted data. All interfaces use a 16-bit CRC (CRC-CITT) by default but also support a 32-bit CRC. The sender of a data frame calculates the frame check sequence (FCS). Before it sends a frame, the sender appends the FCS value to the message. The receiver recalculates the FCS and compares its calculation to the FCS from the sender. If there is a difference between the two calculations, the receiver assumes that a transmission error occurred and sends a request to the sender to resend the frame.

Table 4-1 summarizes CRC commands.

Table 4-1 CRC Commands

Purpose
Command
Example

Enable 32-bit CRC

crc size

The example enables 32-bit CRC on a serial interface:

Router(config)# interface serial 3/0:0
Router(config-if)# crc 32

Return to default 16-bit CRC

no crc size

The example disables 32-bit CRC on a serial interface and returns to the default 16-bit CRC:

Router(config)# interface serial 3/0:0
Router(config-if)# no crc 32

Enable 32-bit CRC using the crc 32 command. Before you can enable 32-bit CRC, you must use the interface serial command (followed by the interface address of the interface) to select the interface on which you want to enable 32-bit CRC.

In the example that follows, 32-bit CRC is specified:

Router(config-if)# crc 32

The preceding command example applies to all systems in which the port adapter is supported. Use the no crc 32 command to disable CRC-32 and return the interface to the default CRC-16 (CRC-CITT) setting.

When you have finished, press Ctrl-Z—hold down the Control key while you press Z—or enter end or exit to exit configuration mode and return to the EXEC command interpreter prompt.

Then write the new configuration to NVRAM using the copy running-config startup-config command.

For command descriptions, refer to the Configuration Fundamentals Configuration Guide on Cisco.com.

To check the interface configuration using show commands, proceed to the "Checking the Configuration" section.

Configuring Multichannel ISDN PRI Interfaces

Following are instructions for a basic multichannel ISDN PRI configuration, which includes enabling a controller and specifying IP routing. You might also need to enter other configuration subcommands, depending on the requirements for your system configuration and the protocols you plan to route on the interface. For complete descriptions of configuration subcommands and the configuration options available, refer to the publications listed in the "Related Documentation" section on page viii.

The PRI group must be mapped before the multichannel controller can be configured (there is only one PRI group for each controller). The following are controller commands used to map the PRI group:

isdn switch-type switch-type

controller t1 port-adapter-slot-number/interface-port-number

clock source line

linecode b8zs

framing esf

loopback [diagnostic | local | remote]

shutdown

pri-group [timeslots range {56 | 64}]

where the rangevalue is a number between 1 and 24 for T1 or 1 and 31 for E1. Time slots 1 to 23 represent the B channels, and time slot 24 represents the D channel for T1. Time slots 1 to 15 and 17 to 31 represent the B channels and time slot 16 represents the D channel for E1. You can enter time slots individually and separate them by commas or enter them as a range separated by a hyphen (for example, 1-3, 8, 9-18).


Note If you do not specify the time slots, the controller is configured for 23 B channels (time slots 1 to 23) and one D channel (time slot 24) for T1. The controller is configured for 30 B channels and one D channel (time slot 16) for E1.


In the following procedure for a basic multichannel ISDN PRI configuration, press Return after each configuration step:


Step 1 At the privileged-level prompt, enter configuration mode and specify that the console terminal will be the source of the configuration subcommands:

Router# configure terminal 
Enter configuration commands, one per line. End with CNTL/Z. 
Router(config)# 

Step 2 Identify the ISDN switch type. In the following example, the primary-5ess switch (a switch for the United States) is identified as the switch type:

Router(config)# isdn switch-type primary-5ess


Note The ISDN switch type that you identify is for all ISDN ports installed in the router.


Step 3 Choose a controller (T1 or E1), set the clock source, specify the framing and line code, and PRI group time slots as described in the "Configuring the Controller" section and the "Performing a Basic Interface Configuration" section.

Step 4 Write the new configuration to memory:

Router# write memory

The system displays an OK message when the configuration is stored.

Step 5 Exit the privileged level and return to the user level by entering disable at the prompt:

Router# disable

Router>


This completes the procedure for configuring multichannel ISDN PRI interfaces. Proceed to the "Checking the Configuration" section to check the interface configuration using show commands.

Checking the Configuration

After configuring the new interface, use the show commands to display the status of the new interface or all interfaces, and use the ping command to check connectivity. This section includes the following subsections:

Using show Commands to Verify the New Interface Status

Using the ping Command to Verify Network Connectivity

Using loopback Commands

Using show Commands to Verify the New Interface Status

This section demonstrates how you can use the show commands to verify that new interfaces are configured and operating correctly and that the PA-MC-8TE1+ port adapter appears in them correctly. Sample displays of the output of selected show commands for some of the supported platforms appear in the sections that follow. For complete command descriptions and examples, refer to the publications listed in the "Related Documentation" section on page viii.

If an interface is shut down and you configured it as up, or if the displays indicate that the hardware is not functioning properly, ensure that the interface is properly connected and terminated. If you still have problems bringing up the interface, contact a service representative for assistance.


Note If information about the PA-MC-8TE1+ port adapter is not indicated in show command output, it is probably because the card type has not been specified. Because the PA-MC-8TE1+ port adapter can be configured for E1 or T1 connectivity, you must specify the card type as E1 or T1, as described in "Performing a Basic Interface Configuration" section. There is no default card type. The port adapter is not functional until the card type is set.


This section includes the following subsections:

Using the show controllers Commands

Using the show protocols Command

Using the show running-config Command

Using the show startup-config Command

Using the show version or show hardware Commands

Using the show diag Command

Display the types of port adapters installed in your system (and specific information about each) using the show diag slot command, where slot is the port adapter slot in the Cisco 7200 series routers, Cisco 7200 VXR routers, Cisco 7201 router, Cisco 7301 router, or Cisco 7401ASR router, the module slot in a Cisco 7304 PCI Port Adapter Carrier Card in a Cisco 7304 router, and the interface processor slot in Cisco 7500 series routers with a VIP. In the FlexWAN module, the show diag command is used without the slot designation.


Note The outputs that appear in this document may not match the output you receive when running these commands. The outputs in this document are examples only.


The following sections provide some platform-specific output examples using the show diag command:

Using the ping Command to Verify Network Connectivity

Using the ping command, you can verify that an interface port is functioning properly. This section provides a brief description of this command. Refer to the publications listed in the "Related Documentation" section on page viii for detailed command descriptions and examples.

The ping command sends echo request packets out to a remote device at an IP address that you specify. After sending an echo request, the system waits a specified time for the remote device to reply. Each echo reply is displayed as an exclamation point (!) on the console terminal; each request that is not returned before the specified timeout is displayed as a period (.). A series of exclamation points (!!!!!) indicates a good connection; a series of periods (.....) or the messages [timed out] or [failed] indicate a bad connection.

Following is an example of a successful ping command to a remote server with the address 10.0.0.10:

Router# ping 10.0.0.10 <Return>
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echoes to 10.0.0.10, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/15/64 ms
Router#

If the connection fails, verify that you have the correct IP address for the destination and that the device is active (powered on), and repeat the ping command.

Using loopback Commands

With the loopback test, you can detect and isolate equipment malfunctions by testing the connection between the PA-MC-8TE1+ interface and a remote device such as a modem or a CSU/DSU. The loopback subcommand places an interface in loopback mode, which enables test packets that are generated from the ping command to loop through a remote device or compact serial cable. If the packets complete the loop, the connection is good. If not, you can isolate a fault to the remote device or compact serial cable in the path of the loopback test.

Depending on the mode of the port, issuing the loopback command checks the following path:

When no compact serial cable is attached to the PA-MC-8TE1+ interface port, or if a DCE cable is attached to a port that is configured as line protocol up, the loopback command tests the path between the network processing engine and the interface port only (without leaving the network processing engine and port adapter).

When a DTE cable is attached to the port, the loopback command tests the path between the network processing engine and the near (network processing engine) side of the DSU or modem to test the PA-MC-8TE1+ interface and compact serial cable.

Specify loopback for a T1 controller and T1 channel using the loopback command. There are three main loopback modes: diagnostic, local (line and payload), and remote (iboc and esf). Specify the loopback format using the loopback [diagnostic | local | remote] command.


Note To shut down the T1 controller, use the shutdown command at the controller prompt.


Examples of specific loopback modes for the T1 controller follow:

Diagnostic loopback mode loops the outgoing transmit signal back to the receive signal and sends an alarm indication signal (AIS) to the network. The syntax of the loopback diagnostic command is as follows:

loopback [diagnostic]

The following example sets the first T1 into diagnostic loopback:

Router# config t
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)# controller t1 2/0
Router(config-controller)# loopback diagnostic

Local loopback mode loops the incoming signal back to the line.The syntax of the loopback local command is as follows:

loopback [local {payload | line}]

The following example sets the first T1 into local loopback:

Router# config t
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)# controller t1 2/0
Router(config-controller)# loopback local payload

Remote loopback mode causes the far end to loop its receive signal back to transmit. The syntax of the loopback remote command follows:

loopback [remote {esf line | iboc | esf payload}]

The following example sets the first T1 into remote line inband loopback:

Router# config t
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)# controller t1 2/0
Router(config-controller)# loop remote esf line

E1 Loopback Examples

Specify loopback for an E1 controller using the loopback command. There are two main loopback modes: diagnostic and local (line and payload). Specify the loopback format using the loopback [diagnostic | local] command.

To shut down the E1 controller, use the shutdown command at the controller prompt.

Examples of specific loopback modes for the E1 controller follow:

Diagnostic loopback mode loops the outgoing transmit signal back to the receive signal and sends an AIS out to the network. The syntax of the loopback diagnostic command is as follows:

loopback [diagnostic]

The following example sets the first E1 into diagnostic loopback:

Router# config t
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)# controller E1 2/0
Router(config-controller)# loopback diagnostic

Local loopback mode loops the incoming signal back to the line.The syntax of the loopback local command is as follows:

loopback [local {payload | line}]

The following example sets the first E1 into local loopback:

Router# config t
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)# controller E1 2/0
Router(config-controller)# loopback local payload
