To set the number of data bits per character that are interpreted and generated by hardware, use the databits line configuration command.
Syntax Description
| 5 | Five data bits per character. |
| 6 | Six data bits per character. |
| 7 | Seven data bits per character. |
| 8 | Eight data bits per character. |
Default
The value is 8.
Command Mode
Line configuration.
Usage Guidelines
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.
Example
The following example changes the data bits to 7 on the auxiliary port.
Switch(config)# line aux 0 Switch(config-line)# databits 7

To set the number of data bits per character that are interpreted and generated by software, use the data-character-bits line configuration command.
Syntax Description
| 7 | Seven data bits per character. |

default-value exec-character-bits
To define the EXEC character width for either 7 bits or 8 bits, use the default-value exec-character-bits global configuration command.
Syntax Description
Default
The value is 7.
Command Mode
Global configuration.
Usage Guidelines
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.
Example
The following example selects the full 8-bit ASCII character set for EXEC banners and prompts.

Example
The following example describes a 3174 controller on async interface 0.

To group access lists, use the dialer-list list global configuration command. To disable automatic dialing, use the no form of this command.
Syntax Description
Default
None.
Command Mode
Global configuration.
Usage Guidelines
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.
Table 4-1 : Dialer-List List Command Access List Types and Numbers
Examples
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.
The following example classifies all other IP packets as interesting and permits them to initiate calls.
Then the following command places list 101 into dialer access group 1.
Related Commands
To display a list of files on a Flash memory device, use the dir EXEC command.
Syntax Description
Default
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.
Command Mode
EXEC.
Usage Guidelines
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:
Examples
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.
The following example displays the long version of the same device:

dnsix-nat authorized-redirection
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.
Syntax Description
Default
An empty list of addresses.
Command Mode
Global configuration.
Usage Guidelines
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.
Example
The following example specifies that the address of the collection center authorized to change the primary and secondary addresses is 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.
Syntax Description
Default
Messages are not sent.
Command Mode
Global configuration.
Usage Guidelines
An IP address must be configured before audit messages can be sent.
Example
The following example configures an IP address as the address of the host to which DNSIX audit messages are sent:
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.
Syntax Description
Default
No alternate IP address is known.
Command Mode
Global configuration.
Usage Guidelines
When the primary collection center is unreachable, audit messages are sent to the secondary collection center instead.
Example
The following example configures an IP address as the address of an alternate host to which DNSIX audit messages are sent:
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.
Syntax Description
Default
Disabled.
Command Mode
Global configuration.
Usage Guidelines
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.
Example
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.
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.
Syntax Description
Default
One message is sent at a time.
Command Mode
Global configuration.
Usage Guidelines
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.
Example
The following example configures the system to buffer five audit messages before transmitting them to a collection center:
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.
Syntax Description
Default
Disabled.
Command Mode
Global configuration.
Usage Guidelines
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.
Example
In the following example, the switch attempts to generate a configuration file compatible with Cisco IOS Release 11.1:
