To continue your PA-E3 port adapter installation, you must configure the serial 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:
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:
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.
After you verify that the new PA-E3 is installed correctly (the enabled LED goes on), use the privileged-level configure command to configure the new interfaces. Have the following information available:
If you installed a new PA-E3 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-E3 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 interfaces on a PA-E3, 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:
Before you remove an interface that you will not replace, replace a compact coaxial cable, or replace port adapters, use the shutdown command to shut down (disable) the interfaces to prevent anomalies when you reinstall the new or reconfigured interface processor. 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 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 serial subcommand (followed by the interface address of the interface), and then enter the shutdown command. Table 5-1 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.

 |
Note If you need to shut down additional interfaces, enter the interface serial command (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. Table 5-2 provides examples.
| Platform | Command | Example |
|---|---|---|
Catalyst RSM/VIP2 in Catalyst 5000 family switches | show interfaces serial, followed by slot/port (port-adapter-slot-number/ | The example is for interface 0 on a port adapter in port adapter slot 1.

Router# show interfaces serial 1/1/0 Serial 1/1/0 is administratively down, line protocol is down [Additional display text omitted from this example] |
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.
Following are instructions for a basic configuration: enabling an interface, specifying IP routing, and setting up external timing on a DCE interface. 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.
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>
Router# configure terminal Enter configuration commands, one per line. End with CNTL/Z. Router(config)#
Step 2 Specify the first interface to configure by entering the interface serial subcommand, followed by the interface address of the interface you plan to configure. (The command for your port adapter may be different, for example, interface atm.) Table 5-3 provides examples.
| Platform | Command | Example |
|---|---|---|
Catalyst RSM/VIP2 in Catalyst 5000 family switches | interface serial, followed by slot/port (port-adapter-slot-number/ | The example is for the first interface of a port adapter in port adapter slot 0. Router(config)# interface serial 0/0 Router(config-if)# |
Cisco 7120 series routers | interface serial, followed by slot/port (port-adapter-slot-number/ | The example is for the first interface of a Router(config)# interface serial 3/0 Router(config-if)# |
Cisco 7140 series routers | interface serial, followed by slot/port (port-adapter-slot-number/ | The example is for the first interface of a Router(config)# interface serial 4/0 Router(config-if)# |
Cisco 7200 series routers | interface serial, followed by slot/port (port-adapter-slot-number/ | The example is for the first interface of a Router(config)# interface serial 6/0 Router(config-if)# |
Cisco uBR7223 router | interface serial, followed by slot/port (port-adapter-slot-number/ | The example is for the first interface of a Router(config)# interface serial 1/0 Router(config-if)# |
Cisco uBR7246 router | interface serial, followed by slot/port (port-adapter-slot-number/ | The example is for the first interface of a Router(config)# interface serial 2/0 Router(config-if)# |
VIP2 or VIP4 in Cisco 7000 series or Cisco 7500 series routers | interface serial, followed by slot/port adapter/port (interface-processor-slot-number/ | The example is for the first interface of a Router(config)# interface serial 1/1/0 Router(config-if)# |
Step 3 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 4 Add any additional configuration subcommands required to enable routing protocols and set the interface characteristics.
Step 5 Reenable the interfaces using the no shutdown command. (See the "Shutting Down an Interface" section.)
Step 6 Configure all additional port adapter interfaces as required.
Step 7 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 8 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.
The PA-E3 supports internal or external clocking, and the clock rate is fixed at 32,064 kbit/s per ITU G.703 and cannot be changed.
Table 5-4 summarizes cyclic redundancy check (CRC) commands. For more information, see the remainder of this section.
| Purpose | Command | Example | Further Information |
|---|---|---|---|
Enable 32-bit CRC. | crc size | The example enables 32-bit CRD on a serial interface: Router(config)# interface serial 3/0 Router(config-if)# crc 32 | |
Return to default 16-bit CRC. | no crc size | The example disables 32-bit CRD on a serial interface and returns to the default 16-bit CRC: Router(config)# interface serial 3/0 Router(config-if)# no crc 32 |
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.
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. This command functions in the same way on all supported platforms.
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 PA-E3 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 publication. For more information, see the "Related Documentation" section and the "Documentation CD-ROM" section.
You can customize the PA-E3. The features you can customize have default values that will probably suit your environment and need not be changed. However, you might need to enter configuration commands, depending on the requirements for your system configuration and the protocols you plan to route on the interface. Perform the tasks in the following sections if you need to customize the PA-E3.
In interface configuration mode, reduce effective bandwidth (range of 22 to 34010 kilobits per second) by entering the dsu bandwidth configuration subcommand, as in the following example:
router(config-if)# dsu bandwidth 16000
Use the no form of this command to return to the default, 34010.
|
Note The local port configuration must match the remote port configuration. For example, if you reduce the effective bandwidth to 16000 on the local port, you must do the same on the remote port. |
In interface configuration mode, define the DSU interoperability mode by entering the dsu mode [0 | 1] configuration subcommand, as in the following example:
router(config-if)# dsu mode 1
Use the no form of this command to return to the default, 0.
|
Note The local port configuration must match the remote port configuration. For example, if you define the DSU interoperability mode as 1 on the local port, you must do the same on the remote port. You need to know what type of DSU is at the remote port to find out if it interoperates with the PA-E3. For E3 serial interfaces, specify mode 0 for connection from a PA-E3 to another PA-E3 or a Digital Link DSU (DL3100). Specify mode 1 for connection from a PA-E3 to a Kentrox DSU. |
Also refer to the "Interoperability Guidelines for PA-E3 DSUs" section section on for information regarding DSU feature compatibilities.
In interface configuration mode, define set bit in G751 frame (national bit) by entering the national bit [0 | 1] configuration subcommand, as in the following example:
router(config-if)# national bit 1
Use the no form of this command to return to the default, which is 0.
In interface configuration mode, enable E3 scrambling by entering the scramble configuration subcommand, as in the following example:
router(config-if)# scramble
Use the no form of this command to restore the default value, which is disabled.
|
Note The local port configuration must match the remote port configuration. For example, if you enable scrambling on the local port, you must do the same on the remote port. |
In interface configuration mode, specify E3 framing by entering the framing {g751 | bypass}
configuration subcommand, as in the following example:
router(config-if)# framing g751
Use the no form of this command to return to the default, which is G.751 framing.
|
Note If you use the bypass option, scrambling must be set to the default, disabled; the DSU mode must be set to the default, 0; and the DSU bandwidth must be set to the default, 34010. |
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:
Table 5-2 demonstrates how you can use the show commands to verify that new interfaces are configured and operating correctly and that the PA-E3 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-E3 and switch or router.
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 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.
Proceed to the next section, "Using loopback Commands ," to finish checking network connectivity.
Use the loopback {dte | local | network {line | payload} command to troubleshoot the E3 serial port adapter at the physical interface level. The command loops all packets from the E3 interface either back to the interface or from the network back out toward the network. Use the no form of the command to remove the loop.
The following examples of the loopback {dte | local | network {line | payload} command configure loopback modes on the single interface (interface 0) of a one-port E3 serial port adapter in port adapter slot 0 of a VIP2 in chassis slot 10 of a Cisco 7500 series router:
Router# configure terminal Enter configuration commands, one per line. End with CNTL/Z. router(config)# interface serial 10/0/0 router(config-if)# loopback dte
Loopback DTE loops the router output data back toward the router (after the line interface unit).
Router# configure terminal Enter configuration commands, one per line. End with CNTL/Z. router(config)# interface serial 10/0/0 router(config-if)# loopback local
Local loopback loops the router output data back toward the router at the framer.
Router# configure terminal Enter configuration commands, one per line. End with CNTL/Z. router(config)# interface serial 10/0/0 router(config-if)# loopback network line
Network line loopback loops the data back toward the network (before the framer).
Router# configure terminal Enter configuration commands, one per line. End with CNTL/Z. router(config)# interface serial 10/0/0 router(config-if)# loopback network payload
Network payload loopback loops just the payload data back toward the network at the E3 framer.
