Configuring the PA-H


To continue your PA-H port adapter installation, you must configure the HSSI interface. 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

Configuring Half-Duplex and Binary Synchronous Communications in Cisco 7200 Series Routers

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:

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

After you verify that the new PA-H is installed correctly (the enabled LED goes on), use the privileged-level configure command to configure the new interface. 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

Bridging protocols you plan to use

If you installed a new PA-H 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-H 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-H, refer to the appropriate configuration publications listed in the "Related Documentation" section on page ix.

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.)

Shutting Down an Interface

Before you remove an interface that you will not replace, replace a HSSI 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 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 serial subcommand (followed by the interface address of the interface), and then enter the shutdown command.

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.

Table 4-1 shows the shutdown command syntax for the supported platforms.

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 ix.

Performing a Basic Interface Configuration

Following are instructions for a basic configuration, which include 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> 

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

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

Step 2 Specify the interface to configure by entering the interface hssi subcommand, followed by the interface address of the interface you plan to configure.

Table 4-3 gives examples of the interface hssi subcommand for the supported platforms.

Router(config)# interface hssi 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.


Note If you are configuring a DTE interface, proceed to Step 6. If you are configuring a DCE interface, you need to configure the external clock signal, which is described in Step 5.

The example in Step 5 applies to all systems in which the PA-H is supported.


Step 5 Set the clock rate using the clock rate command. (See the next section, "Configuring Timing [Clock] Signals.")

Router(config-if)# clock rate 64000

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.


Note If you want to configure cyclic redundancy checks (CRCs) for your port adapter, proceed to the next section, "Configuring Cyclic Redundancy Checks." Otherwise, proceed to the "Configuring Half-Duplex and Binary Synchronous Communications in Cisco 7200 Series Routers" section.


Configuring Timing (Clock) Signals

All EIA/TIA-232 interfaces support both DTE and DCE mode, depending on the mode of the compact serial cable attached to the port. To use a port as a DTE interface, you need only connect a DTE compact serial cable to the port. When the system detects the DTE mode cable, it automatically uses the external timing signal. To use a port in DCE mode, you must connect a DCE compact serial cable and set the clock speed with the clock rate configuration command. You must also set the clock rate to perform a loopback test. This section describes how to set the clock rate on a DCE port and, if necessary, how to invert the clock to correct a phase shift between the data and clock signals.

Table 4-4 summarizes some of the commands used to configure the clock rate. See the specific sections that follow for further details.

The example is for a serial interface with a nonstandard clock rate of 1234567 kbps.

Router(config)# interface serial 3/0
Router(config-if)# clock rate 1234567

"Setting the Clock Rate"

Remove a clock rate that has been set.

no clock rate

The example is for a serial interface and removes a standard clock rate of 72 kbps.

Router(config)# interface serial 3/0
Router(config-if)# clock rate 7200
Router(config-if)# no clock rate

"Setting the Clock Rate"

Invert the transmit clock signal.

invert-txc

The example inverts the transmit clock signal for a serial interface.

Router(config)# interface serial 3/0
Router(config-if)# invert-txc

"Inverting the Clock Signal"

Change the clock signal back to its original phase.

no invert-txc

The example sets the transmit clock signal for a serial interface back to its original phase.

Router(config)# interface serial 3/0
Router(config-if)# no invert-txc

"Inverting the Clock Signal"

Invert the data signal.

invert data

The example inverts the data stream for both transmit and receive for a serial interface:

Router(config)# interface serial 3/0
Router(config-if)# invert data

"Inverting the Data Signal"


Setting the Clock Rate

The default operation on a PA-H DCE interface is for the DCE device to generate its own clock signal (TxC) and send it to the remote DTE. The remote DTE device returns the clock signal to the DCE (the PA-H). Set the clock rate of an interface using the clock rate subcommand, which specifies the clock rate as a bits-per-second value. This subcommand functions in the same way on all supported platforms.

Before you can assign a clock rate, you must use the interface serial command (followed by the interface address of the interface) to select the interface to which you want to assign the clock rate value.

In the following example, the clock rate is specified as 72 kbps:

Router(config-if)# clock rate 72000

The preceding command example applies to all systems in which the PA-H is supported. Use the no clock rate command to remove the clock rate.

Following are the standard clock rates:

1200, 2400, 4800, 9600, 19200 38400 , 56000 , 64000 ,
72000 , 125000 148000 , 250000, 500000, 800000, 1000000,
1300000, 2000000, 4000000, 8000000

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.


Note Cisco IOS Release 11.2(7a)P or a later release of 11.2 P, or Release 11.1(10)CA or a later release of 11.1CA loaded on your Cisco 7200 series router or on your Cisco 7000 series router or Cisco 7500 series router with a VIP2-40(=) supports nonstandard clock rates (any value from 1200 to 8000000) on PA-H interfaces.

Cisco IOS Release 12.0(3)T or a later release of 12.0T, or Release 12.0(1)XE or a later release of 12.0XE supports nonstandard clock rates on PA-H interfaces installed in the Cisco 7204VXR router and Cisco 7206VXR router.

Cisco IOS Release 11.3(7)NA or a later release of 11.3 NA, or Release 12.0(3)T or a later release of 12.0T loaded on your Cisco uBR7246 router supports nonstandard clock rates (any value from 1200 to 8000000) on PA-H interfaces.

Nonstandard clock rates are rounded (if necessary) to the nearest clock rate that the hardware can support.


Set a nonstandard clock rate for an interface using the clock rate subcommand. Before you can assign a nonstandard clock rate, you must use the interface serial command (followed by the interface address of the interface) to select the interface to which you want to assign the nonstandard clock rate value.

In the following example, a nonstandard clock rate of 1234567 bps is specified:

Router(config-if)# clock rate 1234567

The preceding command example applies to all systems in which the PA-H is supported.
Use the no clock rate command to remove the clock rate.

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.

The following example shows how to use the show running-config command to determine the exact clock rate to which the nonstandard clock rate was rounded:

Router# show running-config
Building configuration...
...
!
interface Serial1/0 (interface Serial3/1/0 on a VIP2)

 no ip address
 clockrate 1151526
!
...

In the preceding example, only the relevant output from the show running-config command is shown; other information is omitted.

Inverting the Clock Signal

Systems that use long cables or cables that are not transmitting the TxC (clock) signal might experience high error rates when operating at higher transmission speeds. If a PA-H DCE port is reporting a high number of error packets, a phase shift might be the problem: inverting the clock might correct this phase shift.

When the EIA/TIA-232 interface is a DTE, the invert-txc command inverts the TxC signal the DTE receives from the remote DCE. When the EIA/TIA-232 interface is a DCE, the invert-txc command inverts the clock signal to the remote DTE port. Use the no invert-txc command to change the clock signal back to its original phase.

Inverting the Data Signal

If you use an EIA/TIA-232 interface on the PA-H port adapter to drive a dedicated T1 line that does not have B8ZS encoding—a method to avoid 15 zeros—you must invert the data stream
(both TXD and RXD) either in the connecting CSU/DSU or on the interface. To invert the data stream coming out of the PA-H, use the invert data command. By inverting the HDLC data stream, the HDLC zero insertion algorithm becomes a ones insertion algorithm that satisfies the T1 requirements.


Note Invert data only on the PA-H interface or on the CSU/DSU; inverting both cancels out both data inversions.


Configuring NRZI Format

All EIA/TIA-232 interfaces on the PA-H support nonreturn-to-zero (NRZ) and nonreturn-to-zero inverted (NRZI) formats. Both formats use two different voltage levels for transmission. NRZ signals maintain constant voltage levels with no signal transitions—no return to a zero voltage level—during a bit interval and are decoded using absolute values: 0 and 1. NRZI uses the same constant signal levels but interprets the absence of data—a space—at the beginning of a bit interval as a signal transition and the presence of data—a mark—as no signal transition. NRZI uses relational encoding to interpret signals rather than determining absolute values.

NRZ format—the factory default on all interfaces—is more common. NRZI format is commonly used with EIA/TIA-232 connections in IBM environments.

Table 4-5 summarizes NRZI format commands.

Router(config-if)# nrzi-encoding mark

The example is for a serial interface with NRZI space encoding specified:

Router(config)# interface serial 3/0
Router(config-if)# nrzi-encoding

Disable NRZI encoding.

no nrzi-encoding

The example disables NRZI encoding on a serial interface:

Router(config)# interface serial 3/0
Router(config-if)# no nrzi-encoding

1 Mark is an optional argument. When mark is used, it means there is no signal transition; there is data (a mark) at the beginning of a bit interval. When mark is not used, it means there is a signal transition; there is no data (a space) at the beginning of a bit interval.


Enable NRZI encoding on any interface using the nrzi-encoding [mark] command, where no argument after the command is interpreted as a signal transition, and mark is interpreted as no signal transition. This command functions in the same way on all supported platforms. Before you can enable NRZI encoding, 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 NRZI encoding.

In the example that follows, NRZI encoding with a signal transition—no argument—is specified:

Router(config-if)# nrzi-encoding 

In the example that follows, NRZI encoding with no signal transition—with argument—is specified:

Router(config-if)# nrzi-encoding mark 

The preceding command examples apply to all systems in which the PA-H is supported.
Use the no nrzi-encoding command to disable NRZI encoding.

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 complete command descriptions and instructions, refer to the Configuration Fundamentals Configuration Guide on Cisco.com.

Configuring Cyclic Redundancy Checks

This section provides an example of how you can configure cyclic redundancy checks (CRCs) on the PA-H.

The PA-H 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 it sends 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.

To enable 32-bit CRC on an interface, enter configuration mode and specify the slot and port address of the interface using the interface hssi subcommand, and then enter the crc32 command. Enter Ctrl-Z to exit from configuration mode.


Note The syntax for the interface hssi subcommand is given in Table 4-3 for all supported platforms.


In the example that follows, the interface on a PA-H on a VIP installed in interface processor slot 1 of a Cisco 7000 series router or Cisco 7500 series router is configured for 32-bit CRC:

Router# configure terminal
Enter configuration commands, one per line.  End with CNTL/Z.
Router(config)#
Router(config)# interface hssi 1/0/0
Router(config-if)# crc32
Ctrl-z

To disable CRC-32 and return to the default CRC-16 setting, specify the slot and port address and use the no crc32 command.


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 section "Configuring Half-Duplex and Binary Synchronous Communications in Cisco 7200 Series Routers." (For additional configuration options and instructions for configuring the PA-H, refer to the appropriate configuration publications listed in the "Related Documentation" section on page ix.)

Configuring Half-Duplex and Binary Synchronous Communications in Cisco 7200 Series Routers

This section explains how to configure EIA/TIA-232 interfaces for half-duplex and Bisync operation in Cisco 7200 series routers, including Cisco 7200 VXR routers and the Cisco 7201 router.


Note Cisco IOS Release 11.2(7a)P or a later release of 11.2P supports half-duplex and Bisync operation on the PA-H in Cisco 7200 series routers.

Cisco IOS Release 11.1(19)CC1 or a later release of 11.1CC, or Release 11.3(4)AA or a later release of 11.3AA supports half-duplex and Bisync operation on the PA-H installed in Cisco 7202 routers.

Cisco IOS Release 12.0(3)T or a later release of 12.0T, or Release 12.0(2)XE or a later release of 12.0XE supports half-duplex and Bisync operation on the PA-H in the Cisco 7204VXR router and Cisco 7206VXR router.

The Catalyst RSM/VIP2, Cisco 7100 series routers, Cisco uBR7246 routers, and the VIP2 do not support half-duplex and Bisync operation on the PA-H.


Use the half-duplex command to configure EIA/TIA-232 interfaces for half-duplex mode; full-duplex mode is the default for low-speed serial interfaces. Serial DCE interfaces in half-duplex mode can be configured for controlled-carrier mode or constant-carrier mode; constant-carrier mode is the default. Controlled-carrier mode sets the EIA/TIA-232 interface to deactivate Data Carrier Detect (DCD) until a transmission is sent to the interface. After a transmission is received, DCD is activated and the interface waits a user-configured amount of time and then transmits the data. After the transmission, the interface waits a user-configured amount of time and then deactivates DCD. Constant-carrier mode activates DCD at all times.

Use the half-duplex controlled-carrier command to configure an EIA/TIA-232 interface for controlled-carrier mode. Use the no half-duplex controlled-carrier command to return the interface to constant-carrier mode.

Follow these steps to configure controlled-carrier mode on an EIA/TIA-232 interface:


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 the interface to configure for controlled-carrier mode using the interface serial subcommand (followed by the interface address of the interface) and then enter the half-duplex controlled-carrier subcommand.

The following example is for the first interface of the port adapter in port adapter slot 1:

Router(config)# interface serial 1/0
Router(config-if)# half-duplex controlled-carrier

Step 3 Specify the length of the timer delay the interface uses when it is configured for controlled-carrier mode by using the following command:

Router(config-if)# half-duplex timer {cts-delay value | cts-drop-timeout value | 
dcd-drop-delay value | dcd-txstart-delay value | rts-drop-delay value | rts-timeout value 
| transmit-delay value}

where value is the length of the timer delay in milliseconds.

The following example specifies a Data Carrier Detect (DCD) drop delay of 100 milliseconds on the first interface of a port adapter in port adapter slot 1:

Router(config)# interface serial 1/0
Router(config-if)# half-duplex timer dcd-drop-delay 100 ms

Table 4-6 lists the default delay settings and the value argument for each timer you can use with the half-duplex timer command.

1 In milliseconds (ms).

2 Clear To Send (CTS).

3 Data Carrier Detect (DCD).

4 Request To Send (RTS).


Step 4 Complete the configuration by pressing Ctrl-Z—hold down the Control key while you press Z—or entering end or exit to exit configuration mode and return to the EXEC command interpreter prompt.

Step 5 Write the new configuration to NVRAM as follows:

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

This completes the procedure for configuring controlled-carrier mode on an EIA/TIA-232 interface. For additional information on configuring half-duplex operation on low-speed serial interfaces, refer to the chapter "Configuring Interfaces" in the Configuration Fundamentals Configuration Guide on Cisco.com.


Note To configure EIA/TIA-232 interfaces for Binary Synchronous (Bisync) operation in Cisco 7200 routers, refer to the "Block Serial Tunneling (BSTUN)" section of the "Configuring Serial Tunnel (STUN) and Block Serial Tunnel (BSTUN)" chapter of the Bridging and IBM Networking Configuration Guide on Cisco.com.

Using the ping Command

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 ix 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 IP 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.
