Configuring the PA-MC-2E1 and PA-MC-8E1
To continue your PA-MC-2E1 or PA-MC-8E1 installation, you must configure the serial 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
•Checking the Configuration
•Testing and Troubleshooting the PA-MC-2E1 or PA-MC-8E1
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 interfaces, proceed to the "Configuring the Interfaces" section.
Configuring the Interfaces
After you verify that the new PA-MC-2E1 or PA-MC-8E1 is installed correctly (the enabled LED goes on), use the privileged-level configure command to configure the new interfaces. 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
•ISDN switch type, for the configuring of ISDN PRI (Table 4-1 lists ISDN service provider switch types)
Note The Catalyst 6000 family FlexWAN module does not support ISDN.
•E1 information, for example, clock source, line code, and framing type
•Channel group and PRI group information and timeslot mapping

If you installed a new PA-MC-2E1 or PA-MC-8E1 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-MC-2E1 or PA-MC-8E1 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-MC-2E1 or PA-MC-8E1, 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 an Interface
•Performing a Basic Interface Configuration
•Controller Configuration Examples
•Customizing the Multichannel E1/PRI Port Adapter
•Using show Commands to Verify the New Interface Status
•Using the ping Command to Verify Network Connectivity
•Using loopback Commands

•Using Status LED Indications
•Checking Bit Errors Using a BERT
Shutting Down an Interface
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 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.
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 4-2 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.
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:
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.
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.
Table 4-4 provides examples of the interface serial subcommand for the supported platforms:

Router(config)# interface serial 1/1/0
|
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 In interface configuration mode, set the encapsulation used by the interface by entering the encapsulation {frame-relay | hdlc | ppp | smds | x25} configuration subcommand, as in the following example:
router(config-if)# encapsulation ppp
Step 5 In interface configuration mode, set the description by entering the description line (up to 80 characters describing this controller) configuration subcommand, as in the following example:
router(config-if)# description PPP channel 5
Step 6 At the privileged-level prompt, enter configuration mode and choose an E1 controller:
Router(config)# controller E1 0/0 (Catalyst RSM/VIP2)
Router(config)# controller E1 3/1/1 (Catalyst 6000 family FlexWAN module)
Router(config)#
controller E1 4/0 (Cisco 7100 series router)
Router(config)# controller E1 1/0 (Cisco 7200 series router)
Router(config)# controller E1 1/0 (Cisco uBR7200 series router)
Router(config)# controller E1 1/0 (Cisco 7201, Cisco 7301, or Cisco 7401ASR router)
Router(config)# controller E1 3/0 (Cisco 7304 PCI Port Adapter Carrier Card in a Cisco
7304 router)
Router(config)# controller E1 1/0/0 (VIP2)
Note For E1 controller examples, see "Controller Configuration Examples" section.
Step 7 Change to controller configuration mode and use the framing [CRC4 | no-CRC4] configuration subcommand to set the framing format, as in the following example:
router(config-controller)# framing crc4
Use the no form of this command to restore the default, CRC4.
Step 8 In controller configuration mode, use the clock source [internal | line] configuration subcommand to set the clock source, as in the following example:
router(config-controller)# clock source internal
Use the no form of this command to restore the default, line.
Step 9 In controller configuration mode, use the channel-group number timeslots value configuration subcommand to set the channel group, as in the following example:
router(config-controller)# channel-group 0 timeslots 1-31
Note The channel-group number can be from 0 to 30, and the timeslot value can be from 1 to 31.
Step 10 To use an E1 port as unframed, in controller configuration mode, use the channel-group number unframed configuration subcommand to set the channel group, as in the following example:
router(config-controller)# channel-group 0 unframed
Step 11 In controller configuration mode, use the pri-group timeslots value configuration subcommand to set the pri group, as in the following example:
router(config-controller)# pri-group timeslots 1-31
Step 12 In controller configuration mode, use the description line (up to 80 characters describing this controller) configuration subcommand to set the description, as in the following example:
router(config-controller)# description Arizona 3 Router; location: building 2
Step 13 In controller configuration mode, use the shutdown configuration subcommand to shut down the controller, as in the following example:
router(config-controller)# shutdown
Note When the multichannel E1/PRI port adapter is being used with AMI encoding, it must be configured as 56k or invert data mode.
To exit controller configuration mode and return to global configuration mode, enter the exit command.
Step 14 Re-enable the interfaces using the no shutdown command. (See the "Shutting Down an Interface" section.)
Step 15 Configure all additional port adapter interfaces as required. See the "Configuring Multichannel E1 Interfaces" section, "Configuring Multichannel E1 ISDN PRI Interfaces" section and related "Specifying E1 Framing" section and "Defining National Reserve Bit" section for instructions and information.
Step 16 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 17 Write the new configuration to NVRAM as follows:
Router# copy running-config startup-config
This completes the procedure for creating a basic configuration.

Customizing the Multichannel E1/PRI Port Adapter
The customizable features of the E1/PRI port adapter have default values that will probably suit your environment and not need to 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 E1/PRI port adapter:
•Configuring Multichannel E1 Interfaces
•Configuring Multichannel E1 ISDN PRI Interfaces
•Specifying E1 Framing
•Defining National Reserve Bit
Configuring Multichannel E1 Interfaces
Following are instructions for a basic multichannel E1 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. For complete descriptions of configuration subcommands and the configuration options available, refer to the publications listed in the "Related Documentation" section.
The channel groups must be mapped before the multichannel E1/PRI controller can be configured. The following are controller commands used to map the channel group (the default variable is listed first):
•controller E1 port-adapter-number/port-number (for Catalyst RSM/VIP2)
controller E1 module-number/port-adapter-bay-number/interface-port-number (for FlexWAN)
controller E1 chassis-slot-number/port-adapter-number/port-number (for VIP)
controller E1 port-adapter-slot number/port-number (for Cisco 7100 series routers, Cisco 7200 series routers, Cisco 7200 VXR routers, Cisco uBR7200 series routers, Cisco 7201 router, Cisco 7301 router, Cisco 7304 PCI Port Adapter Carrier Cards in Cisco 7304 router, and Cisco 7401ASR router)
•clock source [line | internal]
•linecode [ami | hdb3]
•framing [crc4 | no-crc4]
•loopback [diagnostic | local {payload | line}]
•shutdown
•channel-group number timeslots list
The argument number is the channel group 0 to 30.
The argument list is a number between 1 and 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.
Note The Catalyst RSM/VIP2 identifies channel groups as serial interfaces by port adapter (0 or 1), port number (0 or 1), and channel-group number (0 to 30). For example, the address of the multichannel E1/PRI port adapter installed in port adapter slot 1, port 1, and channel group 5, is serial 1/1:5.
The Catalyst RSM/VIP2 supports the PA-MC-8E1/120 multichannel E1/PRI port adapter only.
Note The Catalyst 6000 family FlexWAN module identifies channel groups as serial interfaces by module number, port adapter bay (0 or 1), port number (0 or 1), and channel-group number (0 to 30). For example, the address of the multichannel E1/PRI port adapter installed in port adapter bay 0, port 0, and channel group 5 in a FlexWAN module in slot 3 is serial 3/0/0:5.
The Catalyst 6000 family FlexWAN module supports the PA-MC-8E1/120 multichannel E1/PRI port adapter only.
Note Cisco 7000 series routers and Cisco 7500 series routers identify channel groups as serial interfaces by chassis slot number, port adapter (0 or 1), port number (0 or 1), and channel-group number (0 to 30). For example, the address of the multichannel E1/PRI port adapter installed in chassis slot 4, port adapter slot 1, port 1, and channel group 5, is serial 4/1/1:5.
Note The Cisco 7100 series routers, Cisco 7200 series routers, Cisco 7200 VXR routers, Cisco uBR7200 series routers, Cisco 7201 router, Cisco 7301 router, Cisco 7304 port adapter carrier card in the Cisco 7304 router, and Cisco 7401ASR router identify the PRI group as a serial interface by port adapter slot number, port number (0 or 1), and timeslot 30. For example, the address of the multichannel E1/PRI port adapter installed in port adapter slot 1, port 1, and timeslot 31, is recognized by the system as serial 1/1:30.
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 subcommands:
Router# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.

This completes the procedure for creating a basic channelized E1 configuration. See 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 on Cisco.com.
Configuring Multichannel E1 ISDN PRI Interfaces
Note The Catalyst 6000 family FlexWAN module does not support ISDN.
Following are instructions for a basic multichannel 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. For complete descriptions of configuration subcommands and the configuration options available, refer to the publications listed in the "Related Documentation" section.

Both port adapters: 20 with Cisco IOS 11.2 release and Cisco IOS 11.1CA release |
Rules for determining the allowable number of PRI groups per port adapter:
•Each port can have a maximum of 1 PRI group
•Each PRI group can have 1 - 31 timeslots configured
•The allowable number of PRI groups per port adapter is governed by the maximum number of timeslots used per PRI group
Example 1: PA-MC-8E1 configured with:
1 PRI group of 10 timeslots
1 PRI group of 20 timeslots
1 PRI group of 15 timeslots
1 PRI group of 31 timeslots
1 PRI group of 31 timeslots
Total number of timeslots: 107
107 timeslots is fewer than the 128 timeslots maximum allowable per port adapter. In this case the 5 PRI groups/5 ports can be used for the PA-MC-8E1. (Another 21 timeslots could be configured, for maximum of 128.)
Example 2: PA-MC-8E1 configured with 5 PRI groups of 31 timeslots = 155 timeslots.
This example is not valid because 155 timeslots exceeds the 128 timeslots allowable.
Note The maximum number of channel groups per each 8-port multichannel E1 port adapter is 128.
The PRI group must be mapped before the multichannel E1/PRI 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 port-adapter-number/port-number (for Catalyst RSM/VIP2)
controller E1 port-adapter-slot-number/port-number (for Cisco 7100 series routers, Cisco 7200 series routers, Cisco 7200 VXR routers, Cisco uBR7200 series routers, Cisco 7201 router, Cisco 7301 router, Cisco 7304 port adapter carrier card in the Cisco 7304 router, and Cisco 7401ASR router)
controller E1 chassis-slot-number/port-adapter-number/port-number (for VIP)
•clock source line
•linecode hdb3
•framing crc4
•invert data
•loopback [diagnostic | local {payload | line}]
•shutdown
•pri-group [timeslots list]
pri-group timeslots is a number between 1 and 31. (Timeslots 1 to 15 and 17 to 31 represent the B channels, and timeslot 16 represents the D channel. 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).
Note If you do not specify the timeslots, the controller is configured for 30 B channels (timeslots 1 to 15 and 16 to 31) and one D channel (timeslot 16).
Note The Catalyst RSM/VIP2 identifies the PRI group as a serial interface by port adapter slot (0 or 1), port number (0 or 1), and timeslot 30. For example, the address of the multichannel E1/PRI port adapter installed in port adapter slot 1, port 1, and timeslot 31, is recognized by the system as serial 1/1:31.
The Catalyst RSM/VIP2 supports only the PA-MC-8E1/120 multichannel E1/PRI port adapter.
Note The Catalyst 6000 family FlexWAN module does not support ISDN.
Note The Cisco 7100 series routers, Cisco 7200 series routers, Cisco 7200 VXR routers, Cisco uBR7200 series routers, Cisco 7201 router, Cisco 7301 router, Cisco 7304 port adapter carrier card on Cisco 7304 router, and Cisco 7401ASR router identify the PRI group as a serial interface by port adapter slot number, port number (0 or 1), and timeslot 30. For example, the address of the multichannel E1/PRI port adapter installed in port adapter slot 1, port 1, and timeslot 31, is recognized by the system as serial 1/1:30.
Note Cisco 7000 and Cisco 7500 series routers identify the PRI group as a serial interface by chassis slot number, port adapter slot (0 or 1), port number (0 or 1), and timeslot 30. For example, the address of the multichannel E1/PRI port adapter installed in chassis slot 4, port adapter slot 1, port 1, and timeslot 31, is recognized by the system as serial 4/1/1:31.
In the following procedure for a basic multichannel E1 ISDN PRI configuration, press Return 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 subcommands:
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 primary-5ess (a switch for the United States) is identified as the switch type:
Router(config)# isdn switch-type primary-5ess
Note The ISDN switch type that you identify is for all ISDN ports installed in the router.
Step 3 At the prompt, specify the controller to configure by entering the subcommand controller, followed by E1, and chassis-slot-number/port-adapter-number/port-number (VIP), port-adapter-number/port-number (Catalyst RSM/VIP2), or port-adapter-slot-number/port-number (Cisco 7100 series routers, Cisco 7200 series routers, Cisco 7200 VXR routers, Cisco uBR7200 series routers, Cisco 7201 router, Cisco 7301 routers Cisco 7304 port adapter carrier card in the Cisco 7304 router, and Cisco 7401ASR routers

Router(config-controller)# pri-group timeslots 1,3-5,7
Router(config-controller)#
%LINEPROTO-5-UPDOWN: Line protocol on Interface Serial3/1/1:30,
changed state to down
%LINEPROTO-5-UPDOWN: Line protocol on Interface Serial3/1/1:30,
changed state to up
Router(config-controller)#
Note In the above examples, the line-protocol status for timeslot 31 (listed in the output as timeslot 30) represents the entire PRI group.
Step 8 At the prompt, specify the interface serial type and appropriate address. For multichannel E1 ISDN PRI, the PRI group is configured using timeslot 31, which is recognized by the system as timeslot 30.
Router(config-controller)# interface serial 1/1:30 (Catalyst RSM/VIP2)
Router(config-controller)# interface serial 3/1/1:30 (FlexWAN module)
Router(config-controller)# interface serial 3/1:30 (Cisco 7100 series router)
Router(config-controller)# interface serial 3/1:30 (Cisco 7200 series router)
Router(config-controller)# interface serial 3/1:30 (Cisco 7200 VXR router)
Router(config-controller)# interface serial 3/1:30 (Cisco uBR7200 series router)
Router(config-controller)# interface serial 1/1:30 (Cisco 7201 series router)
Router(config-controller)# interface serial 1/1:30 (Cisco 7301 series router)
Router(config-controller)# interface serial 3/1:30 (Cisco 7304 PCI Port Adapter Carrier
Card in a Cisco 7304 router)
Router(config-controller)# interface serial 1/1:30 (Cisco 7401ASR series router)
Router(config-controller)# interface serial 3/1/1:30 (VIP2)
Step 9 If IP routing is enabled on the system, 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 1.1.15.1 255.255.255.0
Step 10 Add any other configuration subcommands required to enable routing protocols and adjust the interface characteristics.
Step 11 Use the no shutdown command to re-enable the interfaces.
Step 12 After including all of the configuration subcommands, to complete the configuration, enter Ctrl-Z—hold down the Control key while you press Z—to exit configuration mode.
Step 13 Write the new configuration to memory:
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:
This completes the procedure for creating a basic multichannel E1 ISDN PRI configuration. See "Checking the Configuration" section to check the interface configuration using show commands. For dialer interface configuration and additional multichannel E1 ISDN PRI interface configuration, refer to the publications Wide-Area Networking Configuration Guide and Wide-Area Networking Command Reference on Cisco.com.
Specifying E1 Framing
In controller configuration mode, specify E1 framing by entering the framing {crc4 | no-crc4} configuration subcommand, as in the following example:
router(config-controller)# framing crc4
Use the no form of this command to return to the default, CRC4 framing.
Defining National Reserve Bit
In interface configuration mode, define national reserve bit in G.703 frame by entering the national reserve [0-1 | 0-1 | 0-1 | 0-1 | 0-1 | 0-1] configuration subcommand, as in the following example:
router(config-if)# national reserve 0 1 1 0 1 1
Use the no form of this command to return to the default, which is all 0s.
To check the interface configuration using show commands see "Checking the Configuration" section.
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 loopback Commands.
Using show Commands to Verify the New Interface Status
Table 4-6 demonstrates how you can use the show commands to verify that new interfaces are configured and operating correctly and that the PA-MC-2E1 and PA-MC-8E1 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.
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.

Proceed to "Using the ping Command to Verify Network Connectivity" section, to check network connectivity of the PA-MC-2E1 or PA-MC-8E1 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.
Proceed to "Using loopback Commands" section, to finish checking network connectivity.
Using loopback Commands
Should you have difficulty with the multichannel E1/PRI port adapter configuration or installation, you can troubleshoot the multichannel E1/PRI port adapter using the loopback command. Specify loopback for a E1 controller using the loopback command. There are two main loopback modes: diagnostic and local (line and payload).
Specify the loopback format using the loopback [diagnostic | local] command.
Note To shut down the E1 controller, use the shutdown command at the controller prompt.
Diagnostic loopback loops the outgoing transmit signal back to the receive signal and sends an AIS signal to the network. The syntax of the loopback diagnostic command is as follows:
Following are examples of setting the first E1 into diagnostic loopback for various supported platforms:
For the Catalyst RSM/VIP2:
Router# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)# controller E1 2/0
Router(config-controller)# loopback diagnostic

Testing and Troubleshooting the PA-MC-2E1 or PA-MC-8E1
Following are suggested guidelines for troubleshooting the multichannel E1/PRI port adapter, including cyclic redundancy checks, LED indications, and a bit error rate (BER) test. You can also use the ping and loopback commands (described in "Using the ping Command to Verify Network Connectivity" section and "Using loopback Commands" section) for testing and troubleshooting. This section includes the following subsections:
•Configuring Cyclic Redundancy Checks for HDLC
•Using Status LED Indications
•Checking Bit Errors Using a BERT
Configuring Cyclic Redundancy Checks for HDLC
The E1/PRI port adapter uses a 16-bit CRC by default; it also supports a 32-bit CRC.
Cyclic redundancy check (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 of the E1/PRI port adapter), and then enter the command crc 32. Enter Ctrl-Z to exit from configuration mode.
Following are examples of a single E1/PRI interface configured for 32-bit CRC:
In the example that follows, a single E1/PRI interface on a Catalyst RSM/VIP2 is configured for 32-bit CRC:
router# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
router(config)# interface serial 0/0:0
router(config-if)# crc 32
In the example that follows, a single E1/PRI interface on a Catalyst 6000 family FlexWAN module in module slot 3 is configured for 32-bit CRC:
router# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
router(config)# interface serial 3/0/0:0
router(config-if)# crc 32
In the example that follows, a single E1/PRI interface on a Cisco 7100 series router in slot 4 is configured for 32-bit CRC:
router# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
router(config)# interface serial 4/0:0
router(config-if)# crc 32
In the example that follows, a single E1/PRI interface on a Cisco 7206 router, Cisco 7201 router, Cisco 7301 router, or a Cisco 7401ASR router in slot 1 is configured for 32-bit CRC:
router# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
router(config)# interface serial 1/0:0
router(config-if)# crc 32
In the example that follows, a single E1/PRI interface on a Cisco 7304 PCI Port Adapter Carrier Card in a Cisco 7304 router in slot 3 is configured for 32-bit CRC:
router# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
router(config)# interface serial 3/0:0
router(config-if)# crc 32
In the example that follows, a single E1/PRI interface on a VIP in interface processor slot 1 is configured for 32-bit CRC:
Router# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
router(config)# interface serial 1/0/0:0
Router(config-if)# crc 32
To disable CRC-32 and return to the default CRC-16 setting, specify the slot and port address 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 cause the outgoing HDLC data stream to be inverted, use the invert data command (from configuration mode) as in the following example on a Cisco 7206 router:
router# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
router(config)# interface serial 1/0:0
router(config-if)# invert data
To check the interface configuration using show commands, refer to the "Checking the Configuration" section.
Using Status LED Indications
The multichannel E1/PRI port adapter has one status LED per port. Table 4-7 lists various system states and functions that are reflected by the front-panel status LEDs on the multichannel E1/PRI port adapter during the CPU boot process and microcode download.
Table 4-7 LEDs for Port Status
|
|
|
Yellow |
On |
Ramtest has started. |
Green |
On (flashes once) |
Ramtest has completed. |
Yellow |
On |
Waiting for download. |
Green |
On, then goes off |
Download has started. |
Green |
On (flashes once, then goes off) |
Download has completed. |
Note After the multichannel E1/PRI port adapter microcode is booted, the microcode takes control of the LEDs.
During the system bootup process and microcode download, if an error occurs, the port status LEDs flash yellow a number of times, pause, and then repeat the flash. Count the number of flashes to determine the error. Table 4-8 lists the LED error indications that might appear.
Table 4-8 LED Error States
|
|
1 |
Memory tests failed. |
2 |
PLX mailbox test failed. |
3 |
Incomplete data on download. |
4 |
Checksum error on download. |
5 |
Invalid command (flashing does not repeat, but processing continues). |
6 |
Unexpected return from downloaded operational code. |
7 |
Processor exception has occurred. |
In all of the preceding error modes, the CPU continually loops and the system does not proceed to the microcode download.
Once the system successfully completes the CPU boot process and microcode download, the front-panel port status LEDs on the multichannel E1/PRI port adapter show the various system states and functions. (See Table 4-9.)
Table 4-9 LEDs for Port Status Indications after Boot Completion
|
|
|
Green |
On |
Port adapter is receiving good signal. |
Yellow |
On |
Port adapter is in loopback mode. |
None |
Off |
Not receiving good signal. Not in loopback mode. |
Checking Bit Errors Using a BERT
To check bit errors using a bit error rate (BER) tester, use the following command:
[no] E1 bert pattern {2^11 | 2^15 | 2^20 O.153 | 2^20 QRSS | 2^23 | 0s | 1s | alt-0-1}
interval minutes
where
2^15 is an exponential number that represents a pseudorandom repeating pattern that is 32767 bits long
2^20 is a pseudorandom repeating pattern that is 1048575 bits long
2^23 is a pseudorandom repeating pattern that is 8388607 bits long
0s is a pattern of all zeroes (00000000...)
1s is a pattern of all 1s (111111...)
minutes are 1-14400, which designate the time the BER test will run
To stop the BER test, use the optional no form of the command.
Following is an example of this command, where the pseudorandom pattern 2^20 is sent and repeats on the E1 port for 60 minutes:
Router# E1 bert pattern 2^20 interval 60
The BER test command is not saved in NVRAM. The test patterns from the multichannel E1/PRI port adapter are framed test patterns; therefore, they are inserted into the payload of a framed E1 signal.
To display the BER test results, use the following EXEC commands: show controller E1 number or show controller E1 number brief.
