To set the maximum and minimum allowed bit rates for the STU-C profile parameters, use the sdsl bitrate command.
sdsl bitrate bitrate
bitrate | The STU-C upstream and downstream bit rates are identical. The loop characteristics determine the achievable rate. See the allowed ranges and default values in "Usage Guidelines," below. |

12.1(1)DA | This command was introduced. |
Only the alarm subsystem uses the minimum bit rate settings. Cisco IOS asserts an alarm if the line card trains at a rate below the configured minimum bit rate. However, no alarm is generated when alarms are disabled. See alarms, for more information on enabling and disabling alarms.
If alarms are enabled for the profile, setting the SDSL bit rate to 0 disables the associated minimum SDSL bit rate alarm.
The following allowable STU-C bit rate ranges occur in units of Kbps:
 |
Caution This command causes the port to retrain when you change the bit rate parameter. |
Setting a parameter to its current value does not cause a retrain. If a port is training when you change the parameter, the port untrains and retrains to the new parameter.
In this example, the command sets the bit rate of the default profile to 528 kbps downstream and upstream:
DSLAM# configure terminal
DSLAM(config)# dsl-profile default
DSLAM(config-dsl-prof)# sdsl bitrate 528
To display debugging information for a port, use the command
show controllers atm slot#/port#
slot#/port# | The slot number and port number of the port for which you want to display debugging information. The slot range is 1 to 38. The port range is 1 to 8. (These are maximum ranges; your card might have fewer than 8 ports and your chassis might have fewer than 38 slots.) |
There is no default value for this command.

12.0(5)DA | This command was introduced in a previous release. |
This command is primarily for engineering use.
The output for this command varies depending on the interface type. It provides low level diagnostic information specific to the physical layer chipset.
Command output for a DMT interface, for example, includes these items:
 |
Note Output items for SDSL ports will display one value for both upstream and downstream. |
In this example, the command displays debugging information for slot 20, port 1:
DSLAM# show controllers atm 20/1
None
To display DSL, DMT, CAP, and ATM status for a port, use the show dsl interface atm command.
show dsl interface atm slot#/port#slot#/port# | The slot number and port number for the port whose status you want to display. The slot range is 1 to 38. The port range is 1 to 8. (These are maximum ranges; your card might have fewer than 8 ports and your chassis might have fewer than 38 slots.) |
There is no default value for this command.

To display a specific profile and all ports to which the profile is currently attached, and those port settings, use the show dsl profile command.
show dsl profile [profile-name][profile-name] | (Optional.) The name of the profile you want to display. |
If you omit the profile-name argument, this command displays profile information for all existing profiles.
Exec
| Release | Modification |
|---|---|
12.0(5)DA | This command was introduced in a previous release. |
This command displays port configuration settings for selected profiles.
In this example, the command displays the command profile named test1:
DSLAM# show dsl profile test1
To display the status of the DSL subscriber ports on a chassis, use the show dsl status exec command.
show dsl status slot#/port# [cap | dmt | sdsl]
slot#/port# | The slot number and port number for the port whose status you want to display. The slot range is 1 to 38. The port range is 1 to 8. (These are maximum ranges; your card might have fewer than 8 ports and your chassis might have fewer than 38 slots.) |
cap | dmt | sdsl | (Optional.) Provides additional information for the specified interface type. These keywords are useful for debugging lines. |
None
Exec
| Release | Modification |
|---|---|
12.0(5)DA | This command was introduced in a previous release. |
12.1(1)DA | The cap | dmt | sdsl keywords were added. |
This command displays the following information for each DSL port on a chassis:
|
Note Output items for SDSL ports will display one value for both upstream and downstream. |
In this example, the command displays status for all of the DSL subscriber ports on the chassis:
DSLAM# show dsl status
Use the show hardware command to display information about the physical cards in the chassis and the chassis type and to determine whether the power supply and fan modules are present.
show hardware
slot# | The slot number for which you want to show card information. The range is 1 to 38. (This is the maximum range; your chassis might have fewer than 38 slots.) |
There is no default value for this command.
Exec
| Release | Modification |
|---|---|
12.0(5)DA | This command was introduced in a previous release. |
The show hardware command displays information about the cards in the chassis and the chassis type and indicates whether the power supply and fan modules are present.
In the event that the show hardware command detects a module mismatch, this command will display the mismatched card type, followed by the word "MISMATCH." See the "slot" section for more information on card mismatches.
The show hardware slot command shows the name of the card in the specified slot, along with IDPROM contents (serial number, CLEI code, and so forth). For example: Slot 21: ATUC-1-4DMT, SERIAL #, H/W rev, S/W rev, CLEI code.
The show hardware chassis command shows the manufacturing information for the NI-2 motherboard, NI-2 daughter card, I/O controller, power module, backplane, and chassis type, chassis name, manufacturer's name, H/W revision, Serial #, Asset ID, Alias, CLEI code.
|
Note If a Flexi line card displays as ATU-C Flex, that slot is not provisioned and is not operational. You must use the slot command to provision the slot for either DMT or CAP line coding before the Flexi line card becomes operational. |
In this example, the command displays hardware information for the card in slot 4:
DSLAM# show hardware slot 4
To display the online insertion and removal (oir) status of line card slots, use the show oir status exec command.
show oir status [slot#]
slot# | (Optional.) The slot number for which you want to show card information. The range is 1 to 38.(This is the maximum range; your chassis might have fewer than 38 slots.) |
If you omit slot#, the system displays the status of all the slots in the chassis.
Exec
| Release | Modification |
|---|---|
12.0(5)DA | This command was introduced in a previous release. |
The show oir status command reports the status of line card slots in the DSLAM chassis. The reported status is one of the following:
When the NI-2 cannot communicate with a line card, the NI-2 provides no entry for the slot where the card is located. The show oir status command displays a history of attempts to communicate with the line card.
|
Note After a 4DMT line card has loaded a new image, it may still display as operationally down if the microcode is being updated. Use the show dsl interface command to examine the running card status. |
The command in this example displays status information for all slots:
DSLAM# show oir status
To display the running configuration for every currently defined profile, including the default profile, use the show running-config command.
show running-configThis command has no keywords or arguments.
There is no default value for this command.
Exec
| Release | Modification |
|---|---|
12.0(5)DA | This command was introduced in a previous release. |
This command tells you which ports are attached to each profile. Use show dsl profile to display configuration settings for selected profiles.
In this example, the command shows the running configuration:
DSLAM# show running-config
To disable a port, use the shutdown command. To enable a port, use the no form of the command.
shutdownThis command has no keywords or arguments.
Enabled (no shutdown)
Interface configuration
| Release | Modification |
|---|---|
12.0(5)DA | This command was introduced in a previous release. |
Use shutdown to disable a port. Use no shutdown to enable a disabled port.
In this example, the command enables slot 20, port 1:
DSLAM# configure terminal
DSLAM(config)# interface atm 20/1
DSLAM(config-if)# no shutdown
None
To provision a slot for a specific card type, or to change the line coding for a Flexi line card, use the slot command.
slot slot# cardtype
slot# | The number of the slot you want to provision. The range is 1 to 38. Note The number of slots varies by chassis. The Cisco 6130 has 38 slots, the Cisco 6160 has 34 slots, and the Cisco 6260 has 32 slots. |
cardtype | The line card type for which you want to configure the slot. The valid card types are
Note Some line cards do not function in all NI-2 DSLAM systems. For example, the Cisco 6100 system supports only a dual-port CAP ATU-C line card. Consult the hardware documentation for your DSLAM to determine which line cards it supports. |
There is no default value for this command.
Global configuration
| Release | Modification |
|---|---|
12.0(5)DA | This command was introduced. |
12.1(1)DA | New card types were added. |
Use the slot command to provision a slot for a line card, and to provision a Flexi line card for CAP or DMT line coding.
Card mismatch error conditions include the following:
If you attempt to provision an empty slot, the minor alarm "MODULE-MISSING" asserts.
|
Note You must provision a 4-port Flexi line card for CAP or DMT line coding before it will operate. After you provision the Flexi card for CAP or DMT, the system downloads line card firmware to the Flexi card. The download process takes about a minute. Do no remove the card, reboot the card, or reboot the system during the download. |
The 4-port Flexi line card is spectrally incompatible with both the 8-port IDSL line card and the 4-port SDSL (STU-C) line card. If you install spectrally incompatible cards in the same of the chassis, the lines served by those cards can suffer reduced performance. For best performance in a chassis with a mixture of line card types, always install Flexi cards on one side of the chassis and install IDSL and SDSL cards on the opposite side.
The command in this example provisions slot 30 for a 4-port Flexi DMT line card.
DSLAM# configure terminal
DSLAM(config)# slot 30 ATUC-4FLEXIDMT
To set the subtend node identifier, use the subtend-id command.
subtend-id node#
node# | The identifier you assign to this subtend node or to the specified subtend interface. The range is 0 to 12. |
The default subtend ID is 0 (zero).
Global configuration or interface configuration. See the "Usage Guidelines" below for details.
| Release | Modification |
|---|---|
12.0(5)DA | This command was introduced in a previous release. |
12.0(8)DA | The ability to assign a subtend ID to an interface was added. |
You must assign to each subtended node a subtend identifier that is unique within its local subtend tree. If this condition is not met, some subscribers might not have fair access to the network.
The node at the top of the subtend tree—that is, the node that is connected to the trunk—must have the subtend ID 0. (Subtend ID 0 is the default.)
You can use the subtend-id command in global configuration mode or in interface configuration mode:
The command in this example sets the subtend node identifier of this chassis to 12:
DSLAM# configure terminal
DSLAM(config)# subtend-id 12
The command in this example sets the subtend node identifier to 6 on port 0/2:
DSLAM# configure terminal
DSLAM(config)# interface atm 0/2
DSLAM(config-if)# subtend-id 6
None
