Configuring the PA-MC-E3
To continue your PA-MC-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:
•Using the EXEC Command Interpreter
•Configuring the Interfaces
•Checking the Configuration
Using the EXEC Command Interpreter
You modify the configuration of your router through the software command interpreter called the EXEC (also called enable mode). You must enter the privileged level of the EXEC command interpreter with the enable command before you can use the configure command to configure a new interface or change the existing configuration of an interface. The system prompts you for a password if one has been set.
The system prompt for the privileged level ends with a pound sign (#) instead of an angle bracket (>). At the console terminal, use the following procedure to enter the privileged level:
Step 1 At the user-level EXEC prompt, enter the enable command. The EXEC prompts you for a privileged-level password as follows:
Step 2 Enter the password (the password is case sensitive). For security purposes, the password is not displayed.
When you enter the correct password, the system displays the privileged-level system prompt (#):
To configure the new interfaces, proceed to the "Configuring the Interfaces" section.
Configuring the Interfaces
After you verify that the new PA-MC-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:
•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
•Clock timing source you plan to use for each new interface and clock speeds for external timing.
If you installed a new PA-MC-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-MC-E3 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-E3, refer to the appropriate configuration publications listed in the "Related Documentation" section on page viii.
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
•Configuring the PA-MC-E3
•Configuring a BERT on an E1 Line
•Configuring Cyclic Redundancy Checks
Shutting Down an Interface
Before you remove an interface that you will not replace, replace a coaxial 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 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.
Table 4-1 shows the shutdown command syntax for the supported platforms.
When you have finished, press Ctrl-Z—hold down the Control key while you press Z—or enter end or exit to exit configuration mode and return to the EXEC command interpreter.

Step 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 viii.
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 4-3 provides examples of the interface serial subcommand for the supported platforms.

|
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 Re-enable 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
Configuring the PA-MC-E3
Following are the procedures to configure the E3 controller, E1 lines, and serial interfaces for the PA-MC-E3. Note that all of these procedures are optional except for "Configuring E1 Lines":
•Configuring the E3 Controller
•Configuring E1 Lines
•Configuring the Serial Interface
These procedures are followed by a sample configuration in the "Configuration Example" section.
Configuring the E3 Controller
If you do not modify the E3 controller configuration of the PA-MC-E3, the configuration defaults in Table 4-4 are used:
Table 4-4 PA-MC-E3 Controller Defaults
|
|
Clock source |
line |
National reserve bit |
1 |
Idle pattern |
0x55 |
This procedure is optional, however, if you need to change any of the default configuration attributes, follow these steps:
Step 1 Select the E3 controller and enter controller configuration mode:
Router(config)# controller E3 0/0 (Catalyst RSM/VIP2)
Router(config)# controller E3 3/0/0 (Catalyst 6000 family FlexWAN module)
Router(config)# controller E3 1/0 (Cisco 7200 series router)
Router(config)# controller E3 1/0 (Cisco uBR7200 series router)
Router(config)# controller E3 1/0 (Cisco 7201, Cisco 7301)
Router(config)# controller E3 3/0 (Cisco 7304 PCI Port Adapter Carrier Card in a Cisco
7304 router)
Router(config)# controller E3 1/0/0 (Cisco 7000 and 7500 series routers with VIP)
Note The port number for the PA-MC-E3 is always 0.
Step 2 Change the clock source used by the E3 controller:
Router(config-controller)# clock source {internal | line}
Step 3 Change the national reserve bit.
Router(config-controller)# national bit {0 | 1}
Step 4 Change the idle pattern.
Router(config-controller)# idle pattern hex-number
Configuring E1 Lines
You can configure the E1 lines as any of the following four configuration options:
•Channelized
•Fractional
•Unframed
•PRI ISDN
If you assign only one channel group to an E1 line, it is a fractional E1 line. If you assign more than one channel group to an E1 line, it is a channelized E1 line.
For channelized (e1 channel-group command), fractional (e1 channel-group command), and unframed (e1 unframed command) configurations, each configured channel group, which might contain individual timeslots and/or ranges of timeslots, uses only one of the 128 available logical channels. For example, if you assign the range of timeslots 3-7 to a channel group, only one logical channel is used. Likewise, if you assign just timeslot 3 to a channel group, only one logical channel is used.
For PRI ISDN (e1 pri-group command) configurations, each timeslot you assign to a PRI group for a configured E1 line, including each timeslot within a range of timeslots, uses one of the 128 available logical channels. For example, if you assign the range of timeslots 3-7 to a PRI group, five logical channels are used (because you assigned timeslots 3, 4, 5, 6, and 7), whereas if you assign just timeslot 3 to a PRI group, only one logical channel is used.
After you configure the E1 lines, they are recognized by the software as a serial interface, and all configuration commands for a serial interface are available. You can configure the serial interface to carry data traffic with the encapsulation of PPP, HDLC, SMDS, and Frame Relay. For information on configuring a serial interface, see the "Configuring the Serial Interface" section.
Changing the E1 Channel Default Settings
If you do not modify the E1configuration of the PA-MC-E3, the configuration defaults in Table 4-5 are used:
Table 4-5 PA-MC-E3 E1 Channel Defaults
|
|
Clock source |
line |
National reserve bit pattern |
0x1f1 |
Framing format |
crc4 |
If you need to change any of the default configuration attributes, follow these steps:
Step 1 Select the E3 controller and enter controller configuration mode:
Router(config)# controller E3 0/0 (Catalyst RSM/VIP2)
Router(config)# controller E3 3/0/0 (Catalyst 6000 family FlexWAN module)
Router(config)# controller E3 1/0 (Cisco 7200 series router)
Router(config)# controller E3 1/0 (Cisco uBR7200 series router)
Router(config)# controller E3 1/0 (Cisco 7201, Cisco 7301)
Router(config)# controller E3 3/0 (Cisco 7304 PCI Port Adapter Carrier Card in a Cisco
7304 router)
Router(config)# controller E3 1/0/0 (Cisco 7000 and 7500 series routers with VIP)
Note The port number for the PA-MC-E3 is always 0; the e1 line is a value from 1 to 16.
Step 2 Change the clock source used by the E3 controller:
Router(config-controller)# e1 line clock source {internal | line}
Caution
Hardware version 3.1.0 of the PA-MC-E3 port adapter has a limitation on the use of the internal clock. In this hardware, if you change the E1 clock source from line to internal or from internal to line, it is possible, although rare, that the change will cause the E1 line to transmit an invalid E1 framing pattern causing a loss of frame at the far end. To recover from this condition, manually reset the affected E1 line by using the e1 shutdown controller configuration command followed by the no e1 shutdown controller configuration command. To determine the hardware version on the port adapter, use the show controllers e3 EXEC command. You cannot use the e1 shutdown command while running BERT or loopbacks; you must stop these functions first. In addition, you cannot start a BERT or loopback while an E1 line is shut down.
Step 3 Change the national reserve bit pattern:
Router(config-controller)# e1 line national bit hex-number
Step 4 Change the framing format:
Router(config-controller)# e1 line framing {crc4 | no-crc4 | none}
Configuring Channelized E1 Lines
You can configure any of the 16 E1 lines as channelized E1 lines, but you are limited to a total of 128 logical channels. You can group the time slots in these E1 lines into several individual logical channel groups, each of which carries data with different data link layer protocol encapsulations. You can configure timeslot 16 as a data channel, although it is typically used for common channel signaling. Channel associated signaling (CAS) for voice channels and E1 Facilities Data Link (FDL) on timeslot 16 are not supported.
Each logical channel group can be composed of individual 64-kbps timeslots and/or ranges of timeslots, for example, 1, 9, 12-14. Each logical channel group can contain from 1-31 timeslots maximum; the same timeslot cannot be used in more than one logical channel group. Any unused timeslots are filled with programmable idle-channel data.
Note If you assign only one channel group to an E1 line, it is a fractional E1 line. If you assign more than one channel group to an E1 line, it is a channelized E1 line.
To configure a channelized E1 line, following these steps, beginning in global configuration mode:
Step 1 Select the E3 controller and enter controller configuration mode:
Router(config)# controller E3 0/0 (Catalyst RSM/VIP2)
Router(config)# controller E3 3/0/0 (Catalyst 6000 family FlexWAN module)
Router(config)# controller E3 1/0 (Cisco 7200 series router)
Router(config)# controller E3 1/0 (Cisco uBR7200 series router)
Router(config)# controller E3 1/0 (Cisco 7201, Cisco 7301)
Router(config)# controller E3 3/0 (Cisco 7304 PCI Port Adapter Carrier Card in a Cisco
7304 router)
Router(config)# controller E3 1/0/0 (Cisco 7000 and 7500 series routers with VIP)
Step 2 Configure the E1 line (values are 1 to 16) in a logical channel group (values are 0 to 30) and specify the timeslots (values are 1 to 31).
Router(config-controller)# e1 line channel-group number timeslots range
Step 3 Repeat Step 2 for each logical channel group and exit when done.
Router(config-controller)# exit
This configuration creates a serial interface. For more information on serial interfaces, see the "Configuring the Serial Interface" section.
Configuring Fractional E1 Lines
You can configure any of the 16 E1 lines as fractional E1 lines, each of which can be either E1 frames or E1 cyclic redundancy check (CRC) multiframes, as specified by CCITT/ITU G.704 and G.706. A fractional E1 line is a subset of the full E1 bandwidth, which uses Nx64 kbps; where N is a timeslot in the range of 1-31.
Fractional E1 lines contain only a single logical channel group that can be either a single 64-kbps timeslot or a range of timeslots; for example timeslot 1, or timeslots 15-23. Any unused timeslots are filled with programmable idle-channel data (idle pattern controller configuration command).
Note If you assign only one channel group to an E1 line, it is a fractional E1 line. If you assign more than one channel group to an E1 line, it is a channelized E1 line.
To configure a fractional E1 line, follow these steps, beginning in global configuration mode:
Step 1 Select the E3 controller and enter controller configuration mode:
Router(config)# controller E3 0/0 (Catalyst RSM/VIP2)
Router(config)# controller E3 3/0/0 (Catalyst 6000 family FlexWAN module)
Router(config)# controller E3 1/0 (Cisco 7200 series router)
Router(config)# controller E3 1/0 (Cisco uBR7200 series router)
Router(config)# controller E3 1/0 (Cisco 7201, Cisco 7301)
Router(config)# controller E3 3/0 (Cisco 7304 PCI Port Adapter Carrier Card in a Cisco
7304 router)
Router(config)# controller E3 1/0/0 (Cisco 7000 and 7500 series routers with VIP)
Step 2 Configure the E1 line (values are 1 to 16) in a logical channel group (values are 0 to 30) and specify the timeslots (values are 1 to 31).
Router(config-controller)# e1 line channel-group number timeslots range
This configuration creates a serial interface. For more information on serial interfaces, see the "Configuring the Serial Interface" section.
Configuring Unframed E1 Lines
You can configure any of the 16 E1 lines as unframed E1 data lines. Each unframed E1 line contains no framing overhead and is not divided into timeslots.
To configure an unframed E1 line, follow these steps, beginning in global configuration mode:
Step 1 Select the E3 controller and enter controller configuration mode:
Router(config)# controller E3 0/0 (Catalyst RSM/VIP2)
Router(config)# controller E3 3/0/0 (Catalyst 6000 family FlexWAN module)
Router(config)# controller E3 1/0 (Cisco 7200 series router)
Router(config)# controller E3 1/0 (Cisco uBR7200 series router)
Router(config)# controller E3 1/0 (Cisco 7201, Cisco 7301)
Router(config)# controller E3 3/0 (Cisco 7304 PCI Port Adapter Carrier Card in a Cisco
7304 router)
Router(config)# controller E3 1/0/0 (Cisco 7000 and 7500 series routers with VIP)
Step 2 Configure an unframed E1 line (values are 1 to 16).
Router(config-controller)# e1 line unframed
This configuration creates a serial interface. For more information on serial interfaces, see the "Configuring the Serial Interface" section.
Configuring PRI ISDN E1 Lines
You can configure any of the E1 lines to support the PRI ISDN application. You assign a PRI group to the E1 line. Each PRI group can contain from 1-31 timeslots maximum. It is not necessary to allocate all 30 timeslots for the ISDN application. Timeslot 16 is used for common channel signaling. Any unused timeslot are filled with programmable idle-channel data (idle pattern controller configuration command).
To configure an E1 line to support the PRI ISDN, follow these steps, beginning in global configuration mode:
Step 1 Select the E3 controller and enter controller configuration mode:
Router(config)# controller E3 0/0 (Catalyst RSM/VIP2)
Router(config)# controller E3 3/0/0 (Catalyst 6000 family FlexWAN module)
Router(config)# controller E3 1/0 (Cisco 7200 series router)
Router(config)# controller E3 1/0 (Cisco uBR7200 series router)
Router(config)# controller E3 1/0 (Cisco 7201, Cisco 7301)
Router(config)# controller E3 3/0 (Cisco 7304 PCI Port Adapter Carrier Card in a Cisco
7304 router)
Router(config)# controller E3 1/0/0 (Cisco 7000 and 7500 series routers with VIP)
Step 2 Configure the E1 line (values are 1 to 16) as a PRI group and specify the timeslots (values are 1 to 31 the default is all timeslots):
Router(config-controller)# e1 line pri-group [timeslots range]
This configuration creates a serial interface. For more information on serial interfaces, see the "Configuring the Serial Interface" section.
Configuring the Serial Interface
After you configure the E1 lines on the PA-MC-E3, you can continue configuring it as you would a normal serial interface. All serial interface commands might not be applicable to the E1 channel. You can configure the serial interface to carry data traffic with the encapsulation of PPP, HDLC, SMDS, and Frame Relay.
For more information on other commands available for serial interfaces, refer to the "Configure a Synchronous Serial Interface" subsection in the "Configuring Interfaces" chapter of the Configuration Fundamentals Configuration Guide.
To enter interface configuration mode and configure the serial interface that corresponds to an E1 line, enter the interfaces serial command in global configuration mode.
Note When configuring the serial interface, you must specify the e1 line number and channel in addition to the standard slot and port information for each router. For unframed E1 lines, the channel is always zero (for example, interface serial 3/0/0/1:0). For channelized and fractional E1 lines, the channel is the number specified as the channel group number (for example, interface serial 3/0/0/3:20, where 20 is the channel group number). For PRI E1 lines, the channel is always 15 (for example, interface serial 3/0/0/3:15).
Table 4-6 provides examples of the
interface serial subcommand for an E1 line for the supported platforms.

Configuration Example
The following example shows a condensed PA-MC-E3 configuration example in which multiple E1 lines at remote sites are aggregated onto a single E3 line at the edge router. This example concentrates the E1 lines to the router without an E123 multiplexer or E1 CSU/DSU.
In the following example, the PA-MC-E3 in slot 4 is configured as follows:
•E1 line 2 is assigned to channel group 0 and is using all timeslots (full E1 bandwidth)
•E1 line 3 is assigned to channel group 0 and is using timeslots 1 through 15
•E1 line 3 is also assigned to channel group 1 and is using timeslots 16 through 31
•For the E3, the default clock source, national, bit, and idle pattern are used
•For each E1 line, the default framing, national bits, and clock source are used
•Each E1 channel is assigned an IP address
Note that the example below is only a partial example; other interface configuration commands can be assigned to the E1 channel.
For more information, refer to the "Configuring the E3 Controller" section and the "Configuring E1 Lines" section.

Configuring a BERT on an E1 Line
Bit error rate test (BERT) circuitry is built into the PA-MC-E3. Using BERTs you can test cables and signal problems in the field. You can configure any E1 line to connect to the onboard BERT circuitry.
There are two categories of test patterns that can be generated by the onboard BERT circuitry: pseudorandom and repetitive. The former test patterns are exponential numbers and conform to CCITT/ITU O.151 and O.153; the latter test patterns are zeroes or ones, or alternating zeroes and ones.
A description of each type of test pattern follows:
•Pseudorandom patterns:
–2^11 (per CCITT/ITU O.151)
–2^15 (per CCITT/ITU O.151)
–2^20 (per CCITT/ITU O.153)
–2^20 QRSS (per CCITT/ITU O.151)
–2^23 (per CCITT/ITU O.151)
•Repetitive patterns:
–All zeros (0s)
–All ones (1s)
–Alternating zeros (0s) and ones (1s)
Both the total number of error bits received and the total number of bits received are available for analysis. You can select the testing period from 1 minute to 24 hours, and you can also retrieve the error statistics anytime during the BERT. (Note that BER testing for the E3 link is not supported.) When running a BERT, your system expects to receive the same pattern that it is transmitting. To help ensure this, two common options are available:
•Use a loopback somewhere in the link or network.
•Configure remote testing equipment to transmit the same BER test pattern at the same time.
Sending a BERT Pattern on an E1 Line
You can send a BERT pattern on an E1 line with the following controller command:
e1 e1-line-number bert pattern pattern interval time.
where:
•e1-line-number is 1-16
•time is 1-1440 minutes
•pattern is:
–0s, repetitive test pattern of all zeros (as 00000...)
–1s, repetitive test pattern or all ones (as 11111...)
–2^11, pseudo-random test pattern (2,048 bits long)
–2^15, pseudo-random O.151 test pattern (32,768 bits long)
–2^20-O153, pseudo-random O.153 test pattern (1,048,575 bits long)
–2^20-QRSS, pseudo-random QRSS O.151 test pattern (1,048,575 bits long)
–2^23, pseudo-random O.151 test pattern (8,388,607 bits long)
–alt-0-1, repetitive alternating test pattern of zeros (0s) and ones (1s), as 01010101...
Note To terminate a BER test during the specified test period, use the no e1 line bert command.
The following examples show how to configure a BER test to send a BERT pseudorandom pattern of 2^20 through E1 line 10 for 5 minutes for various supported routers:
For a Cisco 7200 series or a Cisco uBR7200 series router:
Router(config)# controller e3 1/0
Router(config-controller)# e1 10 bert pattern 2^20 interval 5
For a VIP2:
Router(config)# controller e3 1/0/0
Router(config-controller)# e1 10 bert pattern 2^20 interval 5
For a Catalyst RSM/VIP2:
Router(config)# controller e3 1/0
Router(config-controller)# e1 10 bert pattern 2^20 interval 5
Viewing BERT Results
To view the BERT results for the above examples, you would enter the following show controllers commands:
For the Cisco 7200 series or a Cisco uBR7200 series router:
Router(config)# show controllers e3 1/0/10
For a VIP2:
Router(config)# show controllers e3 1/0/0/10
For a Catalyst RSM/VIP2:
Router(config)# show controllers e3 1/0/10
Configuring Cyclic Redundancy Checks
Cyclic redundancy check (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.
Table 4-7 summarizes the CRC commands.
Table 4-7 CRC Commands
|
|
|
crc size |
Enable 32-bit CRC. |
The following example enables 32-bit CRD on a serial interface:
Router(config)# interface serial 3/0
Router(config-if)# crc 32
|
no crc size |
Return to default 16-bit CRC. |
The following 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
|
You 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-MC-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 on Cisco.com.
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 4-8 demonstrates how you can use the show commands to verify that new interfaces are configured and operating correctly and that the PA-MC-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 on page viii.

Using the show diag Command
Display the types of port adapters installed in your system (and specific information about each) using the show diag slot command, where slot is the port adapter slot in a Catalyst 5000 family switch, Cisco 7200 series router, Cisco 7200 VXR router, Cisco uBR7200 series router, Cisco 7201 router, Cisco 7301 router, or Cisco 7401ASR router, the module slot in a Cisco 7304 PCI Port Adapter Carrier Card in a Cisco 7304 router, and the interface processor slot in a Cisco 7000 series router or Cisco 7500 series router with a VIP. In the FlexWAN module, the show diag command is used without the slot designation.
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.
Note The slot argument is not required for Catalyst 5000 family switches.

Proceed to the next section, "Using the ping Command to Verify Network Connectivity," to check network connectivity of the PA-MC-E3 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 on page viii 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 the next section, "Using loopback Commands," to finish checking network connectivity.
Using loopback Commands
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 that 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:
The loopback dte command places an interface into loopback data terminal equipment (DTE) mode, which 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 dte
The loopback local command places an interface into local loopback mode, which 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 local
The loopback network line command places an interface into network line loopback mode, which 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 line
The lookback network payload command places the interface into network payload loopback mode, which loops just the payload data back toward the network at the E3 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
In addition to using loopback commands at the physical interface level, you can also use the loopback local command to diagnose problems with cables between the E3 controller and the central switching office at the E3 link level, or to diagnose problems with cables between the port adapter and the central switching office at the E1 line level.
An E3 local loopback simultaneously loops all channels toward the router and loops the E3 link back toward the network.
An E1 local loopback sets both local and line (remote) loopback modes simultaneously and loops data toward the router. An E1 remote line loopback loops the E1 line to the remote end. You can also use this loopback mode with bit error rate (BER) tests.
To set a loopback on the E3 or E1 lines, follow these steps, beginning in global configuration mode:
Step 1 Select the E3 controller and enter controller configuration mode:
Router(config)# controller E3 0/0 (Catalyst RSM/VIP2)
Router(config)# controller E3 3/0/0 (Catalyst 6000 family FlexWAN module)
Router(config)# controller E3 1/0 (Cisco 7200 series router)
Router(config)# controller E3 1/0 (Cisco uBR7200 series router)
Router(config)# controller E3 1/0 (Cisco 7201, Cisco 7301)
Router(config)# controller E3 3/0 (Cisco 7304 PCI Port Adapter Carrier Card in a Cisco
7304 router)
Router(config)# controller E3 1/0/0 (Cisco 7000 and 7500 series routers with VIP)
Step 2 Set a local loopback on the E3 controller:
Router(config-controller)# loopback local
Step 3 Set a local loopback on the E1 line:
Router(config-controller)# e1 line loopback local
