To set the number of data bits per character that are interpreted and generated by hardware, use the databits line configuration command.
databits {5 | 6 | 7 | 8}
5 | Five data bits per character. |
6 | Six data bits per character. |
7 | Seven data bits per character. |
8 | Eight data bits per character. |
8
Line configuration
This command pertains to the auxiliary port only.
The databits line configuration command can be used to mask the high bit on input from devices that generate 7 data bits with parity. If parity is being generated, specify 7 data bits per character. If no parity generation is in effect, specify 8 data bits per character. The other keywords are supplied for compatibility with older devices and generally are not used.
The following example changes the data bits to 7 on the auxiliary port.
Switch(config)# line aux 0
Switch(config-line)# databits 7
data-character-bits
terminal data-character-bits
terminal databits
To set the number of data bits per character that are interpreted and generated by software, use the data-character-bits line configuration command.To return the character bits to the default, use the no form of this command
data-character-bits {7 | 8}
7 | Seven data bits per character. |
8 | Eight data bits per character. |
8
Line configuration
The data-character-bits line configuration command does not work on hardwired lines.
The following example sets the number of data bits per character for virtual terminal line 1 to 7.
Switch(config)# line vty 1
Switch(config-line)# data-character-bits 7

This command affects only the bindings in the configuration server's database. It has no effect on the LANE components.
The named emulated LAN must exist in the configuration servers database before using this command. If the default name-to-emulated LAN name binding already exists, it is replaced by the new binding.
The default-name command is a subcommand of the global lane database command.

To define the EXEC character width for either 7 bits or 8 bits, use the default-value exec-character-bits global configuration command.
default-value exec-character-bits {7 | 8}
7 | Selects the 7-bit ASCII character set. |
8 | Selects the full 8-bit ASCII character set. |
7
Global configuration
Configuring the EXEC character width to 8 bits allows you to add graphical and international characters in banners, prompts, and so forth. However, setting the EXEC character width to 8 bits can also cause failures. If a user on a terminal that is sending parity enters the command help, an "unrecognized command" message is displayed because the system is reading all 8 bits and the eighth bit is not needed for the help command.
The following example selects the full 8-bit ASCII character set for EXEC banners and prompts.
Switch# default-value exec-character-bits 8
exec-character-bits
special-character-bits
terminal exec-character-bits
terminal special-character-bits
To configure the flow control default value from a 7-bit width to an 8-bit width, use the default-value special-character-bits global configuration command.

8 | Selects the full 8-bit character set. |
7

Configuring the special character width to 8 bits enables you to add graphical and international characters in banners, prompts, and so forth.
The following example selects the full 8-bit special character set.

To delete any file on a Flash memory device, use the delete privileged EXEC command.
delete [device:] filename
device: | Device containing the file to be deleted. (The colon (:) is required.) Valid devices are as follows: · bootflash: This device is the internal Flash memory. · slot0: This device is the first PCMCIA slot on the ASP card and is the initial default device. · slot1: This device is the second PCMCIA slot. |

Privileged EXEC
To add a description to an interface configuration, use the description interface configuration command. Use the no form of this command to remove the description.
description string
string | Comment or a description to help you remember what is attached to this interface. |
No description is added.
Interface configuration
The description command is meant solely as a comment to be put in the configuration to help you remember what certain interfaces are used for. The description appears in the output of the following EXEC commands: show startup-config, show interfaces, and show running-config.
The following example describes a 3174 controller on async interface 0.
Switch(config)# interface async 0
Switch(config-if)# description 3174 Controller for test lab
show atm interface
show running-config
show startup-config
To display a list of files on a Flash memory device, use the dir EXEC command.
dir [/all | /deleted] [/long] [device:] [filename]
/all | (Optional) Lists deleted files, undeleted files, and files with errors. |
/deleted | (Optional) Lists only the deleted files. |
/long | (Optional) Displays additional information about the files listed, including the following information: · File's index number (#). · Whether the file contains an error (E) or is deleted (D). · File's type (1 = configuration file, 2 = image file). The switch displays these values only when the file's type is certain. When the file's type is unknown, the system displays a zero or FFFFFFFF in this field. · File's Cyclic Redundant Checksum (crc). · Offset into the file system of the next file (seek). · Length of file's name (nlen). · Length of the file itself (length). · The date/time file was created (date/time). · File's name (name). |
device: | (Optional) Device containing the file(s) to list. (The colon (:) is required.) Valid devices are as follows: · bootflash: This device is the internal Flash memory. · slot0: This device is the first PCMCIA slot on the ASP card and is the initial default device. · slot1: This device is the second PCMCIA slot. |
filename | (Optional) Name of the file(s) to display on a specified device. The files can be of any type. You can use wildcards in the filename. A wildcard character (*) matches all patterns. Strings after a wildcard are ignored. |
The initial default device is slot0:. Otherwise, the default device is that specified by the cd command. When you omit all keywords and arguments, the switch displays only undeleted files for the default device specified by the cd command in short format.
EXEC
If you omit the device, the switch uses the default device specified by the cd command.
When you use one of the keywords (/all, /deleted, /long), the system displays file information in long format. The long format includes the following categories:
When you omit all keywords (/all, /deleted, /long), the system displays file information in short format. Short format includes the following categories:
The following example instructs the switch to list undeleted files for the default device specified by the cd command. Notice that the switch displays the information in short format because no keywords are used.
