To continue your PA-T3 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.
If you installed a new PA-T3 port adapter or if you want to change the configuration of an existing interface, you must enter configuration mode using the configure command. If you replaced a PA-T3 port adapter that was previously configured, the system recognizes the new PA-T3 port adapter interfaces and brings each of them up in their existing configuration.
After you verify that the new PA-T3 port adapter is installed correctly (the enabled LED goes on), use the privileged-level configure command to configure the new interfaces. Be prepared with the information you need, such as the following:
For a summary of the configuration options available and instructions for configuring interfaces on the PA-T3 port adapter, refer to the appropriate configuration publications listed in the "Related Documentation" section.
Configuration commands are executed from the privileged level of the EXEC command interpreter, which usually requires password access. Contact your system administrator, if necessary, to obtain access. (See the "Using the EXEC Command Interpreter" section for an explanation of the privileged level of the EXEC.)
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 is 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#
Proceed to the following sections to configure the new interfaces.
Before you remove an interface that you will not replace, replace a compact serial 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 Crtl-Z. Router(config)#
Step 3 Specify the slot/port address of the first interface that you want shut down by entering the subcommand interface as described in .
| Platform | Command | Example |
|---|---|---|
Cisco 7200 series or Cisco uBR7200 | interface, followed by the type (serial) and slot/port (port adapter slot number/0) | Router(config)# interface serial 1/0 |
VIP2 or VIP4 | interface, followed by the type (serial) and slot/port (interface processor slot number/0) | Router(config)# interface serial 1/1/0 |
Catalyst RSM/VIP2 | interface, followed by the type (serial) and port adapter slot number/interface port number (port adapter slot number/0) | Router(config)# interface serial 0/0 |
Cisco 7120 | interface, followed by the type (serial) and port adapter number/interface port number | Router(config)# interface serial 3/0 |
Cisco 7140 | interface, followed by the type (serial) and port adapter number/interface port number | Router(config)# interface serial 4/0 |
Step 4 Enter the shutdown command as follows:
Router(config-if)# shutdown
Step 5 To shut down additional interfaces, enter the slot/port address (or slot/port address/interface port for a VIP) of each additional 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.
The example that follows is for the Cisco 7100 series, Cisco 7200 series, or Cisco uBR7200 series routers:
Router(config-if)# interface serial 1/0 Router(config-if)# shutdown Router(config-if)# interface serial 1/1 Router(config-if)# shutdown Ctrl-Z Router#
The example that follows is for a VIP:
Router(config-if)# interface serial 1/1/0 Router(config-if)# shutdown Router(config-if)# interface serial 1/1/1 Router(config-if)# shutdown Ctrl-Z Router#
The example that follows is for a Catalyst RSM/VIP2:
Router(config-if)# interface serial 1/0 Router(config-if)# shutdown Router(config-if)# interface serial 1/1 Router(config-if)# 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 Verify that new interfaces are now in the correct state (shutdown). To do so on the Cisco 7100 series, Cisco 7200 series, or Cisco uBR7200 series routers, use the show interfaces serial slot/port command to display the specific interface, or use the show interfaces command, without variables, to display the status of all interfaces in the system.
The example that follows is for Cisco 7100 series, Cisco 7200 series, or Cisco uBR7200 series routers:
Router# show interfaces serial 1/0 Serial 1/0 is administratively down, line protocol is down Hardware is M1T-T3 pa [display text omitted]
To verify that new interfaces are now in the correct state (shutdown) on a VIP, use the show interfaces serial slot/port adapter/interface command to display the specific interface, or use the show interfaces command, without variables, to display the status of all interfaces in the system.
The example that follows is for a VIP:
Router# show interfaces serial 1/1/0 Serial 1/1/0 is administratively down, line protocol is down Hardware is cyBus PODS3 Serial [display text omitted]
To verify that new interfaces are now in the correct state (shutdown) on a Catalyst RSM/VIP2, use the show interfaces serial port adapter/interface command to display the specific interface, or use the show interfaces command, without variables, to display the status of all interfaces in the system.
The example that follows is for a Catalyst RSM/VIP2:
Router# show interfaces serial 1/0 Serial 1/0 is administratively down, line protocol is down Hardware is cyBus PODS3 Serial [display text omitted]
Step 8 Reenable the interfaces. To do so, repeat the previous steps, but use the no shutdown command in Step 4, and then write the new configuration to memory as follows.
The example that follows is for the Cisco 7100 series, Cisco 7200 series, or Cisco uBR7200 series routers:
Router(config)# interface serial 1/0 Router(config-if)# no shutdown Ctrl-Z Router# Router# copy running-config startup-config [OK] Router# show interfaces serial 1/0 Serial 1/0 is up, line protocol is up Hardware is M1T-T3 pa [display text omitted]
The example that follows is for a VIP:
Router(config)# interface serial 1/1/0 Router(config-if)# no shutdown Ctrl-Z Router# Router# copy running-config startup-config [OK] Router# show interfaces serial 1/1/0 Serial 1/1/0 is up, line protocol is up Hardware is M1T-T3 pa [display text omitted]
The example that follows is for a Catalyst RSM/VIP2:
Router(config)# interface serial 1/0 Router(config-if)# no shutdown Ctrl-Z Router# Router# copy running-config startup-config [OK] Router# show interfaces serial 1/0 Serial 1/0 is up, line protocol is up Hardware is M1T-T3 pa [display text omitted]
For complete descriptions of software configuration commands, refer to the publications listed in the "Related Documentation" section.
The following steps make up a basic interface configuration for the PA-T3 serial port adapter. 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:
router# disable router>
router# configure terminal Enter configuration commands, one per line. End with CNTL/Z. router(config)#
Step 2 Specify the interface to configure:
router(config)# interface serial 3/0
router(config)# interface serial 1/0/0
router(config)# interface serial 0/0
Step 3 If IP routing is enabled on the system, change to interface configuration mode and use the ip address configuration subcommand to assign an IP address and subnet mask to the interface, as in the following example:
router(config-if)# ip address 10.0.0.0 10.255.255.255
Step 4 In interface configuration mode, choose the internal clock source by entering the clock source configuration subcommand, as in the following example:
router(config-if)# clock source internal
Use the no form of this command to restore the default clock source, which is line.
Step 5 In interface configuration mode, change the shutdown state to up and enable the interface as follows:
router(config-if)# no shutdown
Step 6 Configure additional interfaces as required.
Step 7 When you have included all of the configuration subcommands to complete the configuration, press Ctrl-Z to exit configuration mode.
Step 8 Write the new configuration to nonvolatile memory as follows:
router# copy running-config startup-config [OK] router#
To check the interface configuration using show commands, proceed to the section "Using show Commands to Display Interface and System Information" section .
The following example shows a typical configuration for the PA-T3 serial port adapter on a Cisco 7500 series router:
router> enable router# configure terminal router(config)# interface serial router(config)# interface serial 1/0/0 router(config)# ip address 10.0.0.0 10.255.255.255 router(config-if)# clock source internal router(config-if)# no shutdown router(config-if)# ^Z
You can customize the PA-T3 serial port adapter. The features you can customize have default values that probably suit your environment and do not require change. 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-T3 serial port adapter.
In interface configuration mode, reduce effective bandwidth (range of 22 to 44210 kbps) 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, which is 44210.
 |
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 | 2] 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, which is 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-T3 port adapter. For T3 serial interfaces, specify mode 0 for connection from a T3 serial port adapter to another PA-T3 serial port adapter or a Digital Link DSU (DL3100). Specify mode 1 for connection from a PA-T3 serial port adapter to a Kentrox DSU. Specify mode 2 for connection from a PA-T3 serial port adapter to a Larscom DSU. |
See the "Interoperability Guidelines for PA-T3 Serial Port Adapter DSUs" section for information regarding DSU feature compatibilities.
In interface configuration mode, enable T3 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. |
See the "Interoperability Guidelines for PA-T3 Serial Port Adapter DSUs" section for information regarding DSU feature compatibilities.
In interface configuration mode, specify T3 framing by entering the framing {c-bit | m13 | bypass} configuration subcommand, as in the following example:
router(config-if)# framing c-bit
Use the no form of this command to return to the default, which is C-bit 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, 44210. |
In interface configuration mode, set the cable length (range of 0 to 450 feet), as in the following example:
router(config-if)# cablelength 250
Use the no form of this command to return to the default, which is 10 feet.
The PA-T3 serial port adapter uses a 16-bit CRC by default; it also supports a 32-bit CRC.
CRC is an error-checking technique that uses a calculated numeric value to detect errors in transmitted data. The sender of a data frame divides the bits in the frame message by a predetermined number to calculate a remainder or frame check sequence (FCS). Before sending the frame, the sender appends the FCS value to the message so that the frame contents are exactly divisible by the predetermined number. The receiver divides the frame contents by the same predetermined number that the sender used to calculate the FCS. If the result is not 0, the receiver assumes that a transmission error occurred and sends a request to the sender to resend the frame.
|
Note To enable 32-bit CRC on an interface, follow Steps 1 and 2 of the preceding procedure (enter configuration mode and specify the slot and port address [and the interface port number for a VIP] of the PA-T3 serial port adapter), and then enter the command crc 32. Enter Ctrl-Z to exit from configuration mode. |
For a Cisco 7100 series, Cisco 7200 series, or Cisco uBR7200 series router, use the following example:
router# configure terminal Enter configuration commands, one per line. End with CNTL/Z. router(config)# router(config)# interface serial 3/0 router(config-int)# crc 32 Ctrl-z
For a VIP, use the following example:
router# configure terminal Enter configuration commands, one per line. End with CNTL/Z. router(config)# router(config)# interface serial 1/0/0 router(config-if)# crc 32 Ctrl-z
For a Catalyst RSM/VIP2, use the following example:
router# configure terminal Enter configuration commands, one per line. End with CNTL/Z. router(config)# router(config)# interface serial 0/0 router(config-if)# crc 32 Ctrl-z
To disable CRC-32 and return to the default CRC-16 setting, specify the slot and port address (and the interface port number for a VIP) and use the no crc 32 command. For complete command descriptions and instructions, refer to the related software documentation.
|
Note When enabling a 32-bit CRC on an interface, ensure that the remote device is also configured for a 32-bit CRC. Both the sender and the receiver must use the same CRC setting. |
To check the interface configuration using show commands, proceed to the following section, "Checking the Configuration ."
After configuring the new interface, use the show commands to display the status of the new interface or all interfaces, the ping command to check connectivity, and the loopback command to troubleshoot the physical interface.
Use the show commands to verify that the new interfaces are configured and operating correctly:
Step 2 Display all the current port adapters and their interfaces with the show controllers command. Verify that the new PA-T3 serial port adapter appears in the correct slot.
Step 3 Specify one of the new interfaces:
Step 4 Specify the new serial interface:
Step 5 Display the protocols configured for the entire system and for the specific interfaces with the show protocols command. If necessary, return to configuration mode to add or remove protocol routing on the system or on specific interfaces.
Step 6 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 the interface up, ask a service representative for assistance.
For a Cisco 7100 series, Cisco 7200 series, or Cisco uBR7200 series router, to display information about a specific interface, use the show interfaces command with the interface type and port address in the format show interfaces [type slot/port].
The following example of the show interfaces type slot/port command shows all of the information specific to the serial PA-T3 port (interface port 0) in port adapter slot 2:

For Cisco 7100 series, Cisco 7200 series, and Cisco uBR7200 series routers, use the show controllers command to display all the current interface processors and their interfaces. Following is an example of the show controllers command that shows serial port 2/0 on a one-port PA-T3 serial port adapter installed in chassis slot 2 for a Cisco 7200 series router:
router# show controllers 2/0
M1T-Serial: show controller:

Note The slot values displayed by some commands (such as show diag and show controllers cbus) are not relevant to any physical connection; you should disregard these slot values for the Catalyst RSM/VIP2. |
For complete command descriptions and examples for the Cisco 7100 series routers, Cisco 7200 series routers, Cisco uBR7200 series routers, VIP and Catalyst RSM/VIP2, refer to the publications listed in the "Related Documentation" section.
The ping command allows you to verify that an interface port is functioning properly and to check the path between a specific port and connected devices at various locations on the network. After you verify that the system has booted successfully and is operational, you can use the ping command to verify the status of interface ports. Refer to the publications listed in the "Related Documentation" section for detailed command descriptions and examples.
The ping command sends an echo request out to a remote device at an IP address that you specify. After sending a series of signals, the command waits a specified time for the remote device to echo the signals. Each returned signal is displayed as an exclamation point (!) on the console terminal; each signal 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 message [timed out] or [failed] indicates that the connection failed.
Following is an example of a successful ping command to a remote server with the address 10.0.0.0:
router# ping 10.0.0.0 <Return> Type escape sequence to abort. Sending 5, 100-byte ICMP Echoes to 10.0.0.0, 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 server and that the server is active (powered on), and repeat the ping command. Refer to the publications listed in the "Related Documentation" section for complete descriptions of interface subcommands and the available configuration options.
Use the loopback {dte | local | network {line | payload} | remote} command to troubleshoot the PA-T3 serial port adapter at the physical interface level. The command loops all packets from the PA-T3 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} | remote} command configure loopback modes on serial port 0 of a one-port PA-T3 serial port adapter installed in chassis slot 6 of a Cisco 7200 series router:
Router# configure terminal Enter configuration commands, one per line. End with CNTL/Z. router(config)# interface serial 6/0 router(config-if)# loopback dte
Loopback DTE loops the router output data back toward the router (after the line interface unit [LIU]).
Router# configure terminal Enter configuration commands, one per line. End with CNTL/Z. router(config)# interface serial 6/0 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 6/0 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 6/0 router(config-if)# loopback network payload
Network payload loopback loops just the payload data back toward the network at the PA-T3 framer.
Router# configure terminal Enter configuration commands, one per line. End with CNTL/Z. router(config)# interface serial 6/0 router(config-if)# loopback remote
Remote loopback loops the data back toward the network (before the framer at the remote
T3 device).
|
Note Remote loopback mode works with C-bit framing only. The other loopback modes listed above work with C-bit, M13, and bypass framing. See the "Specifying T3 Framing" section for information on configuring C-bit framing. |
