Configuring the PA-2CE1
To continue your PA-2CE1 installation, you must configure the 2CE1 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 PA-2CE1 Interfaces
•Checking the Configuration
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:
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 (#):
To configure the new interface, proceed to the "Configuring the PA-2CE1 Interfaces" section.
Configuring the PA-2CE1 Interfaces
After you verify that the new PA-2CE1 is installed correctly (the enabled LED goes on), use the privileged-level configure command to configure the new interface. Have the following information available:
•ISDN switch type, when configuring ISDN PRI (Table 4-1 lists ISDN service provider
switch types)
•E1 information, for example, line code, framing type, and so on
•Channel group and PRI group information and timeslot mapping
•Protocols and encapsulations you plan to use on the new interfaces
•Protocol specific information, such as internet protocol (IP) addresses, if you plan to configure the interfaces for IP routing
•Whether the new interface will use bridging

If you installed a new PA-2CE1 or if you want to change the configuration of the existing interface, you must enter configuration mode to configure the new interface. If you replaced a PA-2CE1 that was previously configured, the system recognizes the new interfaces and brings each of them up in their existing configuration.
For a summary of the configuration options available and instructions for configuring a PA-2CE1, refer to the appropriate configuration publications listed in the "Related Documentation" section.
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 the Interface
•Performing a Basic Configuration
Shutting Down the Interface
Before you remove an interface that you will not replace, use the shutdown command to shut down (disable) the interface to prevent anomalies when you reinstall the new or reconfigured interface. 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.
Step 3 Shut down the interface by entering the interface serial subcommand (followed by the interface address of the interface), and then enter the shutdown command. Table 4-2 shows 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.

Step 4 Write the new configuration to NVRAM as follows:
Router# copy running-config startup-config
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. Table 4-3 provides examples.

Step 6 Reenable interfaces by doing the following:
a. Repeat Step 3 to reenable 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.
Performing a Basic Configuration
This section contains guidelines for performing a basic channelized E1 configuration and a basic channelized E1 ISDN PRI configuration: 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. This section contains the following subsections:
•Configuring Channelized E1 Interfaces
•Configuring Channelized E1 ISDN Interfaces
Configuring Channelized E1 Interfaces
Channel groups must be mapped before the 2CE1 controller can be configured. Following are controller commands used to map the channel group (the default variable is listed first):
•controller e1 chassis slot number/port adapter number/interface port number
•linecode [ami | hdb3]
•framing [crc4 | no -crc4]
•loopback
•shutdown
•channel-group number timeslots list [speed {48 | 56 | 64}]
number is the channel group 0 to 30.
timeslots is a number between 1 to 31. You can enter timeslots individually and separate them by commas or enter them as a range separated by a hyphen (for example, 1-3, 8, 9-18). Timeslot 0 is an illegal configuration.
speed specifies the DS0 speed of the channel group; 64 kbps is the default.
Note Cisco 7000 series and Cisco 7500 series routers identify channel groups as serial interfaces by chassis slot number, port adapter (0 or 1), interface port number (0 or 1), and channel-group number (0 to 30). For example, the address of the 2CE1 installed in chassis slot 4, port adapter slot 1, interface port 1, and channel group 5 would be serial 4/1/1:5.
Before using the configure command, you must enter the privileged level of the EXEC command interpreter with the enable command. The system prompts you for a password if one has been set.
Use the following procedure to configure the PA-2CE1. Press the Return key after each configuration step, unless otherwise noted.
Step 1 Confirm that the system recognizes the PA-2CE1 by entering the show running-config command:
Router# show running-config
Step 2 Enter configuration mode and specify that the console terminal is the source of the configuration subcommands:
Router# configure terminal
Step 3 At the prompt, specify the controller to configure by entering the command controller, followed by e1, and chassis slot number/port adapter number/interface port number. The following example is for the 2CE1 in chassis slot 3, port adapter slot 1, interface port 1.
Router(config)# controller e1 3/1/1
Step 4 Specify the controller's framing type by entering the framing command:
Router(config-controller)# framing crc4
Step 5 Specify the controller's linecode format by entering the linecode command:
Router(config-controller)# linecode hdb3
Step 6 Specify a channel group and map timeslots to the channel group by entering the channel-group command. The following example specifies channel group 0 and maps timeslots 1, 3 through 5, and 7 to channel group 0:
Router(config-controller)# channel-group 0 timeslots 1,3-5,7
Router(config-controller)#
%LINEPROTO-5-UPDOWN: Line protocol on Interface Serial3/1/1:0,
changed state to down
%LINK-3-UPDOWN: Interface Serial3/1/1:0, changed state to up
Note Each channel group is presented to the system as a serial interface that can be configured individually.
Step 7 If IP routing is enabled on the system, assign an IP address and subnet mask to the channel group with the interface and ip address commands as follows:
Router(config-controller)# interface serial 3/1/1:0
Router(config-if)# ip address 10.1.15.1 255.255.255.0
Step 8 Add any additional configuration commands required to enable routing protocols and adjust the interface characteristics.
Step 9 Use the no shutdown and exit commands respectively to reenable the interface and return to configuration mode as follows:
Router(config-if)#
no shutdown
%LINEPROTO-5-UPDOWN: Line protocol on Interface Serial3/1/1:0,
changed state to up
%LINK-3-UPDOWN: Interface Serial3/1/1:0, changed state to up
Step 10 Repeat Step 6 through Step 9 for additional channel groups and timeslots.
Step 11 After configuring additional channel groups and timeslots, map all unused timeslots to an unused channel group and shut down the unused channel group by entering the channel-group and shutdown commands, respectively.
In the following example, unused timeslots 2, 6, and 8 through 31 are mapped to unused channel group 1, and channel group 1 is shut down:
Router(config)# controller e1 3/1/1
Router(config-controller)# channel-group 1 timeslots 2,6,8-31
Router(config-controller)#
Router(config-controller)# int serial 3/1/1:1
Router(config-if)# shutdown
Router(config)#
%LINEPROTO-5-UPDOWN: Line protocol on Interface Serial3/1/1:1,
changed state to down
%LINEPROTO-5-UPDOWN: Interface Serial3/1/1:1, changed state to
administratively down
Step 12 After including all of the configuration commands, to complete the configuration, 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:
Step 13 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 14 Exit the privileged level and return to the user level by entering disable at the prompt as follows:
This completes the procedure for creating a basic channelized E1 configuration. Proceed to the "Checking the Configuration" section to check the interface configuration using show commands. For additional information about configuring channelized E1 interfaces, refer to the publications Wide-Area Networking Configuration Guide and Wide-Area Networking Command Reference.
Configuring Channelized E1 ISDN Interfaces
The PRI group must be mapped before the 2CE1 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 e1 chassis slot number/port adapter number/interface port number
•linecode hdb3
•framing crc4
•loopback
•shutdown
•pri-group [timeslots list]
pri-group timeslots is a number between 1 to 31. (Timeslots 1 to 15 and 17 to 31 represent the B channels, and timeslot 16 represents the D channel. While the numbering scheme for entering timeslots is 1 to 31, the system recognizes the numbering of timeslots as 0 to 30. The PRI group is configured by using timeslot 16 [the D channel], which is recognized by the system as timeslot 15.) You can enter timeslots individually and separate them by commas or enter them as a range separated by a hyphen (for example, 1-3, 8, 9-18). The default DS0 speed of the PRI group is 64 kbps.
Note If you do not specify the timeslots, the controller is configured for 30 B channels (timeslots 1 to 15 and 17 to 31) and one D channel (timeslot 16).
Note Cisco 7000 series and Cisco 7500 series routers identify the PRI group as a serial interface by chassis slot number, port adapter slot (0 or 1), interface port number (0 or 1), and timeslot 16. For example, the address of the 2CE1 installed in chassis slot 3, port adapter slot 1, interface port 1, and timeslot 16 would be recognized by the system as serial 3/1/1:15.
In the following procedure, press the Return key 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 commands as follows:
Router# configure t
Enter configuration commands, one per line. End with CNTL/Z.
Step 2 Identify the ISDN switch type. In the following example, the switch primary-net5 (a switch for the European Community) is identified as the switch type:
Router(config)# isdn switch-type primary-net5
Note The ISDN switch type that you identify is for all ISDN interface ports installed in the router.
Step 3 Specify the controller to configure by entering the command controller followed by e1, and chassis slot number/port adapter number/interface port number. The example that follows is for the 2CE1 in chassis slot 3, port adapter slot 1, interface port 1:
Router(config)# controller e1 3/1/1
Step 4 Specify the controller's framing type by entering the framing command as follows:
Router(config-controller)# framing crc4
Step 5 Specify the controller's linecode format by entering the linecode command as follows:
Router(config-controller)# linecode hdb3
Step 6 Map timeslots to the controller's PRI group by entering the pri-group command. The following example shows PRI-group timeslots 1, 3 through 5, and 7 (the B channels) selected and mapped to timeslot 16 (the D channel), which is recognized by the system as timeslot 15:
Router(config-controller)# pri-group timeslots 1,3-5,7
Router(config-controller)#
%LINEPROTO-5-UPDOWN: Line protocol on Interface Serial3/1/1:15,
changed state to down
%LINK-3-UPDOWN: Interface Serial3/1/1:15, changed state to up
Note In the above example, the line-protocol status for timeslot 16 (listed in the output as timeslot 15) represents the entire PRI group.
Each PRI group is presented to the system as a serial interface that can be configured individually.
Step 7 If IP routing is enabled on the system, assign an IP address and subnet mask to the PRI group with the interface and ip address commands as follows.
Note For channelized E1 ISDN PRI, the PRI group is configured by using timeslot 16, which is recognized by the system as timeslot 15.
Router(config-controller)# interface serial 3/1/1:15
Router(config-if)# ip address 10.1.15.1 255.255.255.0
Step 8 Add any additional configuration commands required to enable routing protocols and adjust the interface characteristics.
Step 9 Use the no shutdown and exit commands respectively to reenable the interface and return to configuration mode as follows:
Router(config-if)#
no shutdown
%LINEPROTO-5-UPDOWN: Line protocol on Interface Serial3/1/1:15,
changed state to up
%LINK-3-UPDOWN: Interface Serial3/1/1:15, changed state to up
Step 10 After configuring the PRI group and timeslots, map all unused timeslots to an unused channel group and shut down the unused channel group by entering the channel-group and shutdown commands, respectively.
Note Both PA-2CE1 interfaces support simultaneous operation in channelized E1 and ISDN PRI modes.
In the following example, unused timeslots 2, 6, 8 through 15, and 17 through 31 are mapped to unused channel group 2, and channel group 2 is shut down:
Router(config)# controller e1 3/1/1
Router(config-controller)# channel-group 2 timeslots 2,6,8-15,17-31
Router(config-controller)#
Router(config-controller)# interface serial 3/1/1:2
Router(config-if)# shutdown
Router(config)#
%LINEPROTO-5-UPDOWN: Line protocol on Interface Serial3/1/1:2,
changed state to down
%LINEPROTO-5-UPDOWN: Interface Serial3/1/1:2, changed state to
administratively down
Step 11 After including all of the configuration commands, to complete the configuration, 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:
Step 12 Write the new configuration to memory as follows:
Router# copy running-config startup-config
Step 13 The system displays an OK message when the configuration is stored.
Step 14 Exit the privileged level and return to the user level by entering disable at the prompt as follows:
This completes the procedure for creating a basic channelized E1 ISDN PRI configuration. Proceed to the "Checking the Configuration" section to check the interface configuration using show commands. For dialer interface configuration and additional channelized E1 ISDN PRI interface configuration information, refer to the publications Wide-Area Networking Configuration Guide and Wide-Area Networking Command Reference.
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 and loopback commands 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
Table 4-4 demonstrates how you can use the show commands to verify that new interfaces are configured and operating correctly and that the PA-2CE1 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 "Related Documentation" section.

Proceed to the next section, "Using the ping Command to Verify Network Connectivity" to check network connectivity of the PA-2CE1 and switch or router.
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 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
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.
