Configuring the PA-4B-U Interfaces


To continue your PA-4B-U port adapter installation, you must configure the PA-4B-U interfaces. The instructions that follow apply to all supported platforms. Minor differences between the platforms are noted.

This chapter contains the following sections:

Using the EXEC Command Interpreter

Configuring the Interfaces

Checking the Configuration

Using the EXEC Command Interpreter

You can 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 to 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 passwords:

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-mode system prompt (#):

Router#

Configuring the Interfaces

After you verify that the new PA-4B-U is installed correctly (the enabled LED goes on), use the configure command to configure the new interfaces. Have the following information available:

Protocols and encapsulations you plan to use on the new interfaces

Protocol specific information, such as IP addresses if you will configure the interfaces for IP routing

Note Cisco 7200 series routers do not support a combination of installed ISDN PRI and ISDN BRI interfaces. The ISDN switch type (PRI or BRI) that you identify during an ISDN configuration is for all ISDN interface ports installed in the router.


If you installed a new PA-4B-U or if you want to change the configuration of an existing interface, you must use the privileged-level configure command. If you replaced a PA-4B-U that was previously configured, the system will recognize the new PA-4B-U interfaces and bring each of them up in their existing configurations.

For complete descriptions of interface subcommands and the configuration options available for configuring interfaces on a port adapter, refer to the appropriate configuration publications listed in the section


Note Configuration commands are executed from the privileged level of the EXEC command interpreter, which usually requires password access. See the "Using the EXEC Command Interpreter" section and contact your system administrator, if necessary, to obtain access.


This section contains the following configuration subsections for the standard configurations tasks:

Shutting Down an Interface

Performing a Basic Interface Configuration

Shutting Down an Interface

Before you replace an interface cable, replace port adapters, or remove an interface that you will not replace, use the shutdown command to shut down (disable) the interfaces. Doing so prevents anomalies from occurring when you reinstall the new or reconfigured port adapters. 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. (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 will be 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 Specify the slot/port address of the controller that you want shut down by entering the subcommand interface, followed by the type (bri) and port adapter slot number/interface port number. The example that follows is for a PA-4B-U in port adapter slot 1:

Router(config)# interface bri 1/0

Step 4 Enter the shutdown command as follows:

Router(config-cont)# shutdown

Step 5 To shut down additional existing interfaces, enter the port adapter slot number/interface port number of each interface followed by the shutdown command. When you have entered all the interfaces to be shut down, press Ctrl-Z (hold down the Control key while you press Z) or enter end to exit configuration mode and return to the EXEC command interpreter prompt as follows:

Router(config)# interface bri 1/0
Router(config-int)# shutdown
Ctrl-Z
Router#

Step 6 Write the new configuration to memory as follows:

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

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

Step 7 To verify that new interfaces are now in the correct state (shutdown), use the show interfaces bri port adapter slot number/interface port number command to display the specific interface, or use the show interfaces command, without variables, to display the status of all interfaces in the system.

Router# show interfaces bri 1/0

bri1/0 is down, line protocol is down
  Hardware is BRI
[display text omitted]

Step 8 To re-enable the interfaces, repeat the previous steps, but use the no shutdown command; then write the new configuration to memory as follows:

Router(config)# interface bri 1/0
Router(config-int)# no shutdown
Ctrl-Z
Router#

Router# copy running-config startup-config
[OK]
Router# show interfaces bri 1/0

bri1/0 is up, line protocol is up
  Hardware is BRI
[display text omitted]

For complete descriptions of software configuration commands, refer to the publications listed in the

Performing a Basic Interface Configuration

Following are instructions for a basic configuration, which include 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

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>

Note Cisco 7200 series routers identify PA-4B-U interfaces by port adapter slot number and interface port number (0 through 3). For example, the address of the PA-4B-U installed in port adapter slot 4 and interface port 1 would be bri 4/1.



Step 1 At the privileged-level prompt, enter configuration mode and specify that the console terminal will be 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 Identify the ISDN switch type. In the following example, the switch basic-net3 (a switch for the European Union) is identified as the switch type:

Router(config)# isdn switch-type basic-net3

Note The ISDN switch type that you identify is for all BRI interface ports installed in a Cisco 7200 series router.


Step 3 At the prompt, specify the first interface to configure by entering the subcommand interface, followed by the type (bri), and port adapter slot number/interface port number. The example that follows is for the PA-4B-U in port adapter slot 1, interface port 1:

Router(config)# interface bri 1/1

Step 4 At the prompt, assign an IP address and subnet mask to the interface with the ip address configuration subcommand as in the following example:

Router(config-int)# ip address 10.10.10.1 255.255.255.0 
Router(config-int)#

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

Step 6 Use the no shutdown command to re-enable the interfaces. See the "Shutting Down an Interface" section for no shutdown command examples.

Step 7 After including all of the configuration subcommands, to complete the configuration, enter Ctrl-Z (hold down the Control key while you press Z) or enter end to exit configuration mode.

Step 8 Write the new configuration to memory as follows:

Router# copy running-config startup-config

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

Step 9 Exit the privileged level and return to the user level by entering disable at the prompt as follows:

Router# disable

Router>

This completes the procedure for creating a basic configuration. Proceed to the next section to check the interface configuration using show commands. For additional information about configuring ISDN BRI interfaces, refer to the Wide-Area Networking Configuration Guide and Wide-Area Networking Command Reference on Cisco.com.

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 show Commands to Verify the New Interface Status

The following procedure demonstrates how you can use the show commands to verify that new interfaces are configured and operating correctly and that the port adapter appears in them correctly. Sample displays of the output of selected show commands appear in the sections that follow. For complete command descriptions and examples, refer to the publications listed in the


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.


Take the following steps to verify that the new interfaces are configured and operating correctly:


Step 1 Display the system hardware configuration with the show version command. Ensure that the list includes the new BRI interfaces.

Step 2 Specify one of the new BRI interfaces with the show interfaces type port adapter slot/interface port number command and verify that the first line of the display specifies the interface with the correct slot number. Also verify that the interface and line protocol are in the correct state: up or down.

Step 3 Display all ISDN interfaces installed in the router and the ISDN switch type for the interfaces with the show isdn status command. Ensure that the correct ISDN switch type is displayed for the installed ISDN interfaces.

Step 4 Display the protocols configured for the entire system and specific interfaces with the show protocols command. If necessary, return to configuration mode to add or remove protocol routing on the system or specific interfaces.

Step 5 Display the running configuration file with the show running-config command. Display the configuration stored in NVRAM using the show startup-config command. Verify that the configuration is accurate for the system and each interface.


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

(Display text omitted.)

Using the ping Command to Verify Network Connectivity

Use the ping command to verify that an interface port is functioning properly after the system has booted successfully and is operational.

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 command 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 that the connection failed.

Following is an example of a successful ping command to a remote server with the address 10.10.10.1:

Router# ping 10.10.10.1 <Return>
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echoes to 10.10.10.1, 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.
