Command Reference

This chapter describes the Cisco IOS commands that are supported by the Cisco 6200 advanced digital subscriber line access multiplexer (DSLAM). The commands and keywords described in this chapter are routinely used to configure, monitor, and manage the Cisco 6200. Commands and keywords that are not supported or typically used are not described. For more information on Cisco IOS commands, refer to the Cisco IOS Command Reference guides.

You must be in the correct mode to use a command. For information on how to enter the different modes, refer to "Using the Cisco IOS Command Line Interface." The primary command modes used in the Cisco 6200 are listed in Table 5-1.

5.1 Commonly Used Commands

This section documents the commands and command arguments that are typically used to configure and monitor the Cisco 6200 DSLAM. For brief descriptions of other commands available on the Cisco 6200, see Section 5.2, "Other Commands."

5.1.1 alarmcutoff

To turn off audible alarms generated by the Cisco 6200, use the alarmcutoff command.

Command Mode

Privileged EXEC

Usage Guidelines

The Cisco 6200 alarms inform you of problems with the temperature, fans, clock, or data transmission, as well as other problems. You can view the alarm status by using the show dsl alarms command or the show dsl interface command. (For more information on alarms, see "Hardware Description.")

Alarms are also reported through an external chassis alarm interface. You can use this interface to set up remote signals that indicate alarms audibly, visibly, or both. (Other types of alarms, such as CLI and SNMP, are not affected by the alarmcutoff command.)

Example

The command in the following example turns off audible alarms:

c6200# alarmcutoff 

5.1.2 c6200 card

To provision a slot to accept either an NTC or an SLC, use the c6200 card command.

Syntax Description

Command Mode

Global configuration

Usage Guidelines

Use of this command is not required; the system provisions slots automatically when cards are inserted. If you use the c6200 card command to provision the slots in a chassis, the system generates an alarm when the wrong kind of card is inserted in a slot or when a slot is left empty.

You cannot provision or preconfigure an MPC.

Example

In the following example, slot 5 is configured to support an SLC DMT8.

c6200(config)# c6200 card 5 slc1-8-dmt 

5.1.3 clear counters

To reset traffic statistics displayed by show interface commands, use the clear counters command.

Syntax Description

Command Mode

Privileged EXEC

Example

The following example shows how to reset all counters for the show interface command to 0:

c6200# clear counters 
Clear "show interface" counters on all interfaces [confirm]
c6200#

5.1.4 config-register

To change the command register value, use the config-register command.

Syntax Description

Default

The default configuration register value for the Cisco 6200 is either 0x102 or 0x2102.

Command Mode

Global configuration

Usage Guidelines

This command is commonly used as part of the password recovery procedure.

For more information on this command, see the Configuration Fundamentals Command Reference guide for Cisco IOS Release 11.3.

Example

The following example shows how to set the configuration register to 0x102:

c6200(config)# config-register 0x102
c6200(config)#

5.1.5 configure

To enter global configuration mode, use the configure command.

Syntax Description

Command Mode

Privileged EXEC

Usage Guidelines

You must be in global configuration mode to enter configuration commands.

For more information on this command, see the Configuration Fundamentals Command Reference guide for Cisco IOS Release 11.3.

Example

In the following example, the system is set to use configuration commands from the terminal:

cc6200# config
Configuring from terminal, memory, or network [terminal]?  
Enter configuration commands, one per line.  End with CNTL/Z.
c6200(config)#
 

The following example shows the configure terminal command in an abbreviated form:

c6200# conf t
Enter configuration commands, one per line.  End with CNTL/Z.
c6200(config)#

5.1.6 copy

To copy any file from a source to a destination, use the copy command.

Syntax Description

Command Mode

Privileged EXEC

Usage Guidelines

Command keywords that end with a colon (bootflash:, slot0:, slot1:) must be followed by a source or destination file name.

On the MPC, slot 0 is the left PCMCIA slot; slot 1 is the right PCMCIA slot.

For more information on this command, see the Configuration Fundamentals Command Reference guide for Cisco IOS Release 11.3.

Example

In this example, the system configuration currently running is copied into a file named "myconfig" on a tftp server named "myserver":

c6200# copy running-config tftp 
Remote host [myserver]? 
Name of configuration file to write [myconfig]? 
Write file delete on host 3.0.3.1? [confirm]

Building configuration...
 

This example shows how to copy the running configuration to the startup configuration (stored in NVRAM on the MPC card):

c6200# copy running-config startup-config
c6200#
 

This example shows how to copy the file myconfig from the PCMCIA Flash memory card in slot 0 to the file myconfig2 on the card in slot 1:

c6200# copy slot0:myconfig slot1:myconfig2
18241024 bytes available on device slot1, proceed? [confirm]
c6200#

5.1.7 disable

To exit privileged EXEC mode and return to user EXEC mode, enter the disable command.

Command Mode

Privileged EXEC

Usage Guidelines

For more information on this command, see the Configuration Fundamentals Command Reference guide for Cisco IOS Release 11.3.

Example

The example below shows how to go from privileged EXEC to user EXEC mode:

c6200# disable
c6200>

5.1.8 dsl bitrate

To specify the transmission rate for traffic between the customer premises equipment (CPE) and the central office (CO), use the dsl bitrate command. Downstream goes from CO to CPE; upstream goes to CPE from CO.

Syntax Description

Defaults

For SLC 8CAP: 640 kbps downstream and 91 kbps upstream

For SLC 8DMT: 640 kbps downstream and 128 kbps upstream

Command Mode

Interface configuration

Usage Guidelines

The system generates a minor alarm if you configure an explicit bit rate and the modems are not able to train at that rate. If you set the bit rate to auto, the modems train at the highest supportable rate.

In general, the highest bit rates are not attainable at longer loop lengths.

On the SLC 8DMT, if you enter an invalid bit rate, the system rounds down to the nearest valid bit rate. For example, if you enter a downstream bit rate of 7000, the system sets the bit rate to 6976 kbps.

Example

In this example, the DSL bit rate is set to 2688 kbps downstream and 544 kbps upstream:

c6200(config-if)# dsl bitrate downstream 2688 upstream 544 

5.1.9 dsl check-bytes

Specifies the number of check bytes per symbol (DSL frame) used by the forward error correction (FEC) feature. Using more check bytes improves error correction, but also increases overhead, which lowers usable bandwidth.

Syntax Description

Defaults

The default setting is 16 check bytes per symbol in both directions.

Command Mode

Interface configuration

Usage Guidelines

You can set auto mode using the command no dsl check-bytes. In auto mode, the line card determines the best setting based on the line rate.

Cisco recommends that you leave check-bytes set to its default, 16, or to auto mode.

This command is available on DMT interfaces only.

Example

In this example, check bytes per symbol are set to 6 downstream and 10 upstream:

c6200(config-if)# dsl check-bytes downstream 6 upstream 10 

5.1.10 dsl interleaving

Turns off (or turns on) the interleaving feature that mixes bytes of data from different frames on the line. When interleaving is on, error correction is more effective for protecting against impulse (bursty) noise on the line. The drawback to interleaving: it can add significant delay at the sending side. The amount of delay added is equivalent to the interleaving delay value that you set by means of the command dsl int-delay, described below.

Default

By default, interleaving is turned on.

Command Mode

Interface configuration

Usage Guidelines

When you turn interleaving off, data still uses the interleaving path, but delay is set to 0. Cisco recommends that you leave interleaving on.

This command is available on DMT interfaces only.

Example

In this example, interleaving is turned on:

c6200(config-if)# dsl interleaving on 

5.1.11 dsl int-delay

Sets delay values, in msec, for the interleaving feature (see also the dsl interleaving command, above). If bursty or impulse noise is a concern, set interleaving delay to a value greater than the longest expected duration of the noise. If delay is a concern, set interleaving delay as low as possible.

Syntax Description

Defaults

The default setting is 16 msecs of delay in both directions.

Command Mode

Interface configuration

Usage Guidelines

Cisco recommends that you leave interleaving delay set to its default values (16 in both directions).

This command is available on DMT interfaces only.

Example

In this example, interleaving delay is set to 16 msecs in both directions:

c6200(config-if)# dsl int-delay downstream 16 upstream 16 

5.1.12 dsl lbo

This command has been changed to dsl local-tx-power (see below). See also dsl remote-tx-power.

5.1.13 dsl local-tx-power

To adjust the power of the signal transmitted from the Cisco 6200 to the CPE downstream, use the dsl local-tx-power command. (To adjust power in the other direction, see dsl remote-tx-power.)

To avoid crosstalk, use the lowest power possible to achieve the desired bit rate. The default value is full power; the other settings cause the Cisco 6200 interface to transmit at 3, 6, 9, 12, and 15 dB below full power.

Syntax Description

Default

The default power transmit level is full power.

Command Mode

Interface configuration

Usage Guidelines

The local transmit power command is used to balance line power levels between full power, which may cause crosstalk over bundled lines, and lowest power (full power minus 15 dB), which may have signal-to-noise problems over long distances. You should consider reducing power on short, high-quality subscriber lines if they are causing interference on other subscriber lines.

This command is available on CAP interfaces only.

Example

In the following example, the power value is set to -3 dB:

c6200(config-if)# dsl local-tx-power minus_3db 

5.1.14 dsl loopback

Runs a dsl-line or a local loopback test on a DMT interface. Both options are passive loopbacks. (For information on looping CAP interfaces, see the command loopback.)

To display test results, enter the command show dsl interface dsl slot/port.

Syntax Description

Command Mode

Interface configuration

Usage Guidelines

This command configures the Cisco 6200 hardware for a loopback test. External test equipment is required to send the data through a loop and verify that it is looped back correctly.

The port remains in loopback mode until you enter the no dsl loopback command.

This command is available for DMT interfaces only.

Example

In the following example, a dsl-line loopback test is initiated:

c6200(config-if)# dsl loopback dsl-line 

5.1.15 dsl LOSconfig

Controls the issuance of a minor alarm upon loss of signal (LOS), loss of frame (LOF), and loss of cell delineation (LOCD). By default, LOS, LOF and LOCD do cause minor alarms; enter dsl losconfig on to disable the alarm.

Default

By default, LOSconfig is turned off (that is, LOS, LOF and LOCD do cause minor alarms).

Command Mode

Interface configuration

Usage Guidelines

This command is available on DMT interfaces only.

Example

In this example, minor alarms are enabled for LOS, LOF and LOCD:

c6200(config-if)# dsl LOSconfig off 

5.1.16 dsl margin

Allows you to adjust the margin added to the signal-to-noise ratio (SNR) to which the line trains. A higher margin results in fewer errors on the line; a lower margin results in longer reach and tends to increase the bit rate.

Syntax Description

Defaults

The default setting is 6 dB in both directions.

Command Mode

Interface configuration

Usage Guidelines

If the line does not train, try reducing the margin. (This effect varies with loop length.)

This command is available on DMT interfaces only.

Example

In this example, margin is set to 9 dB downstream and 3 dB upstream:

c6200(config-if)# dsl margin downstream 9 upstream 3 

5.1.17 dsl power_boost

Increases the power, in dB, of the signal that the Cisco 6200 sends downstream. Increasing the power improves the reach on the line, but can also cause cross-talk--- resulting in higher error rates or failure to train.

Syntax Description

Defaults

The default setting is 0 dB.

Command Mode

Interface configuration

Usage Guidelines

Cisco recommends against changing the power_boost value. If you do change it, we recommend that you set power_boost to a value no higher than 2 dB. Performance for settings above 2 dB varies with loop conditions.

This command is available on DMT interfaces only.

Example

In this example, power_boost is set to 1 dB:

c6200(config-if)# dsl power_boost 1

5.1.18 dsl quick-training

Turns on (or off) a faster training algorithm that may limit interoperabililty. When quick training is on, the system ignores the options set with the commands dsl symbols-codeword and dsl check-bytes.

Default

By default, quick training is turned off.

Command Mode

Interface configuration

Usage Guidelines

This command is available on DMT interfaces only.

Example

In this example, quick training is turned on:

c6200(config-if)# dsl quick-training on 

5.1.19 dsl remote-tx-power

To adjust the power of the signal transmitted from the CPE to the Cisco 6200 upstream, use the dsl remote-tx-power command. (To adjust power in the other direction, see dsl local-tx-power.)

To avoid crosstalk, use the lowest power possible to achieve the desired bit rate. The default value is full power; the other settings cause the CPE to transmit at 3, 6, 9, 12, and 15 dB below full power.

Syntax Description

Default

The default power transmit level is full power.

Command Mode

Interface configuration

Usage Guidelines

The local transmit power command is used to balance line power levels between full power, which may cause crosstalk over bundled lines, and lowest power (full power minus 15 dB), which may have signal-to-noise problems over long distances. You should consider reducing power on short, high-quality subscriber lines if they are causing interference on other subscriber lines.

This command is available on CAP interfaces only.

Example

In the following example, the power value is set to -3 dB:

c6200(config-if)# dsl remote-tx-power minus_3db 

5.1.20 dsl symbols-codeword

Specifies the number of symbols (DSL frames) per FEC codeword. You can set auto mode using the command no dsl symbols-codeword. In auto mode, the SLC determines the best setting based on the line rate. Auto mode is applied to the line in both directions; you cannot use auto mode in one direction and an explicit value in the other direction. Auto mode is the default setting.

Syntax Description

Defaults

The default setting is auto in both directions.

Command Mode

Interface configuration

Usage Guidelines

Cisco recommends that you leave symbols per codeword set to auto mode, its default. If you choose not to use auto mode, set the number of symbols per codeword so that the FEC codeword does not exceed the maximum size of 255 bytes. The total number of bytes in an FEC codeword includes user data bytes (which depend upon rate) plus check-bytes. (You can set check-bytes using the dsl check-bytes command, described above.)

For a check-bytes setting of 16 bytes per codeword, use these guidelines to select a symbols-codeword value that is appropriate to the bit rate on the line:

• 16 for rates between 32 and 352 kbps
  
  
• 8 for rates between 384 and 800 kbps
  
  
• 4 for rates between 832 and 1728 kbps
  
  
• 2 for rates between 1760 and 3584 kbps
  
  
• 1 for rates between 3616 and 8032 kbps
  
  

For lower check-bytes settings, you can use higher symbols-codeword values at some bit rates.

This command is available on DMT interfaces only.

Example

In this example, symbols per codeword is set to 4 downstream and 2 upstream:

c6200(config-if)# dsl symbols-codeword downstream 4 upstream 2 

5.1.21 dsl subscribername

To assign a subscriber name, use the dsl subscribername command. To return all configuration settings for a particular card/port to default values, use the no dsl subscribername command.

Syntax Description

Default

When you are configuring a port as administratively up by means of the no shutdown command, the system chooses a default subscriber name in the form port-type slot/port---for example, "DSL 5/2."

Command Mode

Interface configuration

Example

In this example, the interface being configured is assigned the name boston:

c6200(config-if)# dsl subscribername boston 
c6200(config-if)# 

5.1.22 dsl-ucode-load

Loads microcode into modems (ports) on the SLC module. See Chapter 4, Configuration Procedures, for details.

Syntax Description

Command Mode

Privileged EXEC

Example

In this example, a file called newcode.bin is loaded from PCMCIA slot 0 to all the modems in the SLC in slot 5:

c6200(config-if)# dsl-ucode-load slot0:newcode.bin 5 all 
c6200(config-if)# 

5.1.23 enable

To enter privileged EXEC mode, use the enable command.

Command Mode

User EXEC

Usage Guidelines

Because many of the privileged commands set operating parameters, privileged access should be password-protected to prevent unauthorized use. If an enable password has not been set, enable mode can be accessed only from the router console.

For more information on this command, see the Configuration Fundamentals Command Reference guide and the Security Command Reference guide for Cisco IOS Release 11.3.

Example

In this example, you enter privileged EXEC mode. The password does not display.

c6200> enable
Password: 
c6200# 

5.1.24 enable password

To set a local password to control access to privileged EXEC mode and other modes, use the enable password command. Use the no form of this command to remove the password requirement.

Syntax Description

Command Mode

Global configuration

Usage Guidelines

For more information on this command, see the Security Command Reference guide for Cisco IOS Release 11.3.

Example

This example shows how to create a password called boston:

c6200-is-password(config)# enable password boston
c6200-is-password(config)#

5.1.25 enable secret

To specify an additional layer of security beyond what the enable password command offers, use the enable secret command. Use the no form of this command to turn off the enable secret function.

Syntax Description

Command Mode

Global configuration

Usage Guidelines

This password should be different from the password created with the enable password command.

This password is displayed in the running configuration as an encrypted string.

For more information on this command, see the Security Command Reference guide for Cisco IOS Release 11.3.

To enter interface configuration mode for port 2 of an SLC card in slot 8, do the following:

c6200(config)# interface dsl 8/2
c6200(config-if)#

5.1.31 linetest

To test the CAP or DMT hardware and the line quality (CAP only), use the linetest command. To view the test results, use the show dsl interface command. If the bit error rate is less than 10^-7, the hardware and line pass the test.

Syntax Description

Command Mode

Privileged EXEC

Usage Guidelines

To view the test results, use the show dsl interface command. If the bit error rate is less than 10^-7, the hardware and line pass the test. The default value for passing the test, 10^-7 bit errors, is an industry standard.

In order to run the line quality test, your Cisco 6200 must be trained to a Cisco 675 CPE that has software version 1.4.2 (or later) installed.

Example

Use the following command to conduct a 10-minute line test on port 3 of card 5:

c6200# linetest dsl 5/3 dmtlocaltest duration 10 
c6200# 

5.1.32 loopback

To run a loopback data transmission test between the Cisco 6200 backplane and the local CAP interface, use the loopback command. (For information on looping DMT interfaces, see the command dsl loopback.)

To display test results, enter the command show dsl interface dsl slot/port.

Command Mode

Interface configuration

Usage Guidelines

This command configures the Cisco 6200 hardware for a loopback test. External test equipment is required to send the data through a loop and verify that it is looped back correctly.

The port remains in loopback mode until you enter the no loopback command.

Example

The following example initiates a loopback test for port 2 of card 8:

c6200(config)# int dsl 8/2
c6200(config-if)# loopback
c6200(config-if)

5.1.33 reload
