To set the number of data bits per character that are interpreted and generated by hardware, use the databits line configuration command. To restore the default data bits per character, use the no form of this 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. |

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

packets | Displays tagged packets switched by this system. The optional if-type (atm, atm-p, cbr, ethernet, or null) and card/subcard/port arguments restrict the display to those packets received or transmitted on the specified interface type or number. This command should be used with care, because it generates output for every packet processed. Furthermore, enabling this command causes fast and distributed tag switching to be disabled for the selected interfaces. Use this command only when traffic on the network is low, so other activity on the system is not adversely affected. |
tdp advertisements | Displays information about the advertisement of tags and interface addresses to TDP peers. |
tdp bindings | Displays information about changes to the TIB used to keep track of tag bindings learned from TDP peers through TDP downstream tag distribution. |

tdp session | Displays TDP session information. See also "Usage Guidelines." |
tdp transport | Used with the connections keyword, this command displays information about the TCP connections used to support TDP sessions. Used with the events keyword, this command displays information about the events related to the TDP peer discovery mechanism, which is used to determine the devices with which to establish TDP sessions. Used with the timers keyword, this command displays TDP discovery and transport timer activity. See also "Usage Guidelines." |
tsp-tunnels events | Displays TSP tunnels events. |
tsp-tunnels signalling | Displays TSP tunnels signalling. |
tsp-tunnels tagging | Displays TSP tunnels tagging. |
Privileged EXEC
When there are a large number of routes and a number of system activities (shutting down interfaces, learning new routes, and so forth), the debug tag-switching atm-tdp routes and debug tag-switching atm-tdp states commands display a lot of information that may interfere with system timing. Most commonly, this affects the normal operation of TDP. You should increase the holdtime value of the TDP by using the tag-switching tdp holdtime command.
TDP sessions are supported by data structures and state machines at three levels:
The debug tag-switching tdp transport commands provide visibility of activity at the transport level, the debug tag-switching tdp session commands at the protocol level, and the debug tag-switching tdp peer state-machine command at the tag distribution level.
To provide an emulated LAN name in the configuration server's database for those client MAC addresses and client ATM addresses that do not have explicit emulated LAN name bindings, use the default-name database configuration command. To remove the default name, use the no form of this command.
default-name elan-name
elan-name | Default emulated LAN name for any LANE client MAC address or LANE client ATM address not explicitly bound to any emulated LAN name. Maximum length is 32 characters. |
No name is provided.
Database configuration
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.
client-atm-address name
lane database
name server-atm-address
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.
default-value special-character-bits {7 | 8}
7 | Selects the 7-bit character set. |
8 | Selects the full 8-bit character set. |
7
Global configuration
Configuring the special character width to 8 bits enables you to add graphical and international characters in banners, prompts, and so forth.

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. |
filename | Name of the file to be deleted. The maximum filename length is 63 characters. |
Privileged EXEC
To add a description to an interface configuration, use the description interface configuration command. To remove the description, use the no form of this command.
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 show startup-config, show interfaces, and show running-config EXEC commands.
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 | Lists deleted files, undeleted files, and files with errors. This option is available only in privileged EXEC command mode. |
/deleted | Lists only the deleted files. This option is available only in privileged EXEC command mode. |
/long | Displays additional information about the files listed. This option is available only in privileged EXEC command mode. The following information is included: · 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 ( · Offset into the file system of the next file ( · Length of file's name ( · Length of the file itself ( · The date/time file was created ( · File's name ( |
device: | 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 | 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.
When you omit all keywords (/all, /deleted, /long), the system displays file information in short format. Short format includes the following categories:
#).
length).
date/time).
name).
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.
Switch# dir -#- -length- -----date/time------ name 1 5393 May 03 1996 14:32:57 startup-config 2 2229876 Apr 11 1997 10:46:10 ls1010-wp-mz.112-4.4.WA3.1.1 3 2261104 Apr 28 1997 11:32:09 ls1010-wp-mz.112-4.4.WA3.1.8 3498632 bytes available (4496760 bytes used)
The following example displays the long version of the same device.
Switch# dir /long -#- ED --type-- --crc--- -seek-- nlen -length- -----date/time------ name 1 .. 1 AE9B32B 21594 14 5393 May 03 1996 14:32:57 startup-conf ig 2 ..
