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. |
The value is 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 0Switch(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.
data-character-bits {7 | 8}| 7 | Seven data bits per character. |
| 8 | Eight data bits per character. |
The value is 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 1Switch(config-line)#data-character-bits 7

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. |
The value is 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. |
The value is 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.
The following example selects the full 8-bit special character set.
Switch# default-value special-character-bits 8
exec-character-bits

To set a delay value for an interface, use the delay interface configuration command. Use the no form of this command to restore the default delay value.
delay tens-of-microseconds| tens-of-microseconds | Integer that specifies the delay in tens of microseconds for an interface or network segment. |
Default delay values can be displayed with the EXEC command show interfaces.
Interface configuration.
The following example sets a 30,000-microsecond delay on ATM interface 3/0/0.
Switch(config)#interface ATM 3/0/0Switch(config-if)#delay 30000
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. 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 0Switch(config-if)#description 3174 Controller for test lab
show atm interface
show running-config
show startup-config
To group access lists, use the dialer-list list global configuration command. To disable automatic dialing, use the no form of this command.
dialer-list dialer-group list access-list-number| dialer-group | Specifies the number of a dialer access group identified in any dialer-group interface configuration command. |
| access-list-number | Specifies the access list number specified in any IP or Novell IPX access lists including Novell IPX extended, Service Access Point (SAP) access lists and bridging type. See Table 4-1 for the supported access list types and numbers. |
None.
Global configuration.
The dialer-list list command applies access lists to dialer access groups to control dialing using DDR. This command applies access lists to dialer access groups defined with the dialer-group command.
Table 4-1 lists the access list types and numbers that the dialer-group command supports.
| Access List Type | Access List Number Range |
|---|---|
| Standard IP | 1 to 99 |
| Extended IP | 100 to 199 |
| Transparent Bridging | 200 to 299 |
| Standard Novell IPX | 800 to 899 |
| Extended Novell IPX | 900 to 999 |
Dialing occurs when an interesting packet (one that matches access list specifications) needs to be output on an interface. Using the standard access list method, packets can be classified as interesting or uninteresting. In the following example, IGRP TCP/IP routing protocol updates are not classified as interesting and do not initiate calls.
access-list 101 deny igrp 0.0.0.0 255.255.255.255 255.255.255.255 0.0.0.0
The following example classifies all other IP packets as interesting and permits them to initiate calls.
access-list 101 permit ip 0.0.0.0 255.255.255.255 0.0.0.0 255.255.255.255
Then the following command places list 101 into dialer access group 1.
Switch# dialer-list 1 list 101
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.
Switch# dir

To set the retransmit count used by the DNSIX Message Delivery Protocol (DMDP), use the dnsix-dmdp retries global configuration command. To restore the default number of retries, use the no form of this command.
dnsix-dmdp retries count| count | Number of times DMDP retransmits a message. It can be a decimal integer from 0 through 200. |
Retransmits messages up to four times or until acknowledged.
Global configuration.
The following example sets the number of times DMDP attempts to retransmit a message to 150:
Switch(config)# dnsix-dmdp retries 150
dnsix-nat authorized-redirection
dnsix-nat primary
dnsix-nat secondary
dnsix-nat source
dnsix-nat transmit-count
To specify the address of a collection center that is authorized to change the primary and secondary addresses of the host to receive audit messages, use the dnsix-nat authorized-redirection global configuration command. To delete an address, use the no form of this command.
dnsix-nat authorized-redirection ip-address| ip-address | IP address of the host from which redirection requests are permitted. |
An empty list of addresses.
Global configuration.
Use multiple dnsix-nat authorized-redirection commands to specify a set of hosts that are authorized to change the destination for audit messages. Redirection requests are checked against the configured list, and if the address is not authorized, the request is rejected and an audit message is generated. If no address is specified, no redirection messages are accepted.
The following example specifies that the address of the collection center authorized to change the primary and secondary addresses is 193.1.1.1.
Switch(config)# dnsix-nat authorization-redirection 193.1.1.1
To specify the IP address of the host to which DNSIX audit messages are sent, use the dnsix-nat primary global configuration command. To delete an entry, use the no form of this command.
dnsix-nat primary ip-address| ip-address | IP address for the primary collection center. |
Messages are not sent.
Global configuration.
An IP address must be configured before audit messages can be sent.
The following example configures an IP address as the address of the host to which DNSIX audit messages are sent:
Switch(config)# dnsix-nat primary 194.1.1.1
To specify an alternate IP address for the host to which DNSIX audit messages are sent, use the dnsix-nat secondary global configuration command. To delete an entry, use the no form of this command.
dnsix-nat secondary ip-address| ip-address | IP address for the secondary collection center. |
No alternate IP address is known.
Global configuration.
When the primary collection center is unreachable, audit messages are sent to the secondary collection center instead.
The following example configures an IP address as the address of an alternate host to which DNSIX audit messages are sent:
Switch(config)# dnsix-nat secondary 193.1.1.1
To start the audit-writing module and to define audit trail source address, use the dnsix-nat source global configuration command. To disable the DNSIX audit trail writing module, use the no form of this command.
dnsix-nat source ip-address| ip-address | Source IP address for DNSIX audit messages. |
Disabled.
Global configuration.
You must issue the dnsix-nat source command before any of the other dnsix-nat commands. The configured IP address is used as the source IP address for DMDP protocol packets sent to any of the collection centers.
The following example enables the audit trail writing module, and specifies that the source IP address for any generated audit messages should be the same as the primary IP address of Ethernet interface 2/0/0.
Switch(config)#dnsix-nat source 128.105.2.5Switch(config)#interface ethernet 2/0/0Switch(config-if)#ip address 128.105.2.5 255.255.255.0
To have the audit writing module collect multiple audit messages in the buffer before sending the messages to a collection center, use the dnsix-nat transmit-count global configuration command. To revert to the default audit message count, use the no form of this command.
dnsix-nat transmit-count count| count | Number of audit messages to buffer before transmitting to the server. Integer from 1 through 200. |
One message is sent at a time.
Global configuration.
An audit message is sent as soon as the message is generated by the IP packet-processing code. The audit writing module can instead buffer up to several audit messages before transmitting to a collection center.
The following example configures the system to buffer five audit messages before transmitting them to a collection center:
Switch(config)# dnsix-nat transmit-count 5
To generate a configuration that is compatible with an earlier Cisco IOS release, use the downward-compatible-config global configuration command. To remove this feature, use the no form of this command.
downward-compatible-config number.number| number.number | Version number of the software separated by a period (.) in the range of 0 through 999999. |
Disabled.
Global configuration.
When this command is configured, the switch attempts to generate a configuration that is compatible with the specified version. Currently, this command affects only IP access lists. Under some circumstances, the software might not be able to generate a fully backward-compatible configuration. In such a case, the software issues a warning message.
In the following example, the switch attempts to generate a configuration file compatible with Cisco IOS Release 11.1:
Switch(config)# downward-compatible-config 11.1
access-list (extended)
access-list (standard)
