To set the number of data bits per character that are interpreted and generated by hardware, use the databits line configuration command.
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.
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.
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.
The debug atm oam-all privileged EXEC command enables all the debug flags for the OAM. Use the no form of the command to disable the debug command.
This command has no arguments or keywords.
To display the transmit and receive OAM traffic, use the debug atm oam-pkt privileged EXEC command. This command also decodes individual OAM cells. Use the no form of the command to disable the debug command.
This command has no arguments or keywords.
To debug the PNNI configuration, use the following debug atm pnni EXEC commands.
To enable the debug printout messages for ATM resource manager, use the debug atm rm privileged EXEC command. To disable the printout message, use the no form of this command.
This command has no arguments or keywords.
To debug the ATM signalling module, use the debug atm sig privileged EXEC commands. Use the no form of the command to disable the debug command.
To enable driver-level debugging of specific remote ports, use the debug ports privileged EXEC command.
If you specify aal5, you can provide the ATM interface number. Use the netclock option to show network clock switching debug information.
To debug the ATM Signalling SSCOP, use the following debug sscop privileged EXEC commands. Use the no form of the command to disable the debug command.
To define the EXEC character width for either 7 bits or 8 bits, use the default-value exec-character-bits global configuration command.
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.
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.
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.
exec-character-bits
special-character-bits
terminal exec-character-bits
terminal special-character-bits
Note This command or some of its parameters might not function as expected in the LightStream 1010 ATM switch environment.
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.
Default delay values can be displayed with the EXEC command show interfaces.
The following example sets a 30,000-microsecond delay on ATM interface 3/0/0.
To delete any file on a Flash memory device, use the delete privileged EXEC command.
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.
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.
show atm interface
show running-config
show startup-config
Note This command or some of its parameters might not function as expected in the LightStream 1010 ATM switch environment.
To group access lists, use the dialer-list list global configuration command. To disable automatic dialing, use the no form of this command.
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
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.
To display a list of files on a Flash memory device, use the dir EXEC command.
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.
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:
· 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 check (crc).
· Offset into the file system of the next file (seek).
· Length of the file's name (nlen).
· Length of the file itself (length).
· Date and time the file was created (date/time).
When you omit all keywords (/all, /deleted, /long), the system displays file information in short format. Short format includes the following categories:
· Length of the file itself (length).
· Date and time the file was created (date/time).
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:
cd
config-register
delete
undelete
To disassemble the instruction stream, use the dis ROM monitor command.
This command has no keywords or arguments.
To return to the EXEC mode by exiting the privileged EXEC mode, use the disable EXEC command.
In the following example, the user is logging out from privilege level 5:
To disconnect an existing network connection, use the disconnect privileged EXEC command.
Note This command or some of its parameters might not function as expected in the LightStream 1010 ATM switch environment.
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.
Retransmits messages up to four times or until acknowledged.
The following example sets the number of times DMDP attempts to retransmit a message to 150:
dnsix-nat authorized-redirection
dnsix-nat primary
dnsix-nat secondary
dnsix-nat source
dnsix-nat transmit-count
Note This command or some of its parameters might not function as expected in the LightStream 1010 ATM switch environment.
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.
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.
Note This command or some of its parameters might not function as expected in the LightStream 1010 ATM switch environment.
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.
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:
Note This command or some of its parameters might not function as expected in the LightStream 1010 ATM switch environment.
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.
No alternate IP address is known.
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:
Note This command or some of its parameters might not function as expected in the LightStream 1010 ATM switch environment.
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.
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.
Note This command or some of its parameters might not function as expected in the LightStream 1010 ATM switch environment.
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.
One message is sent at a time.
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:
Note This command or some of its parameters might not function as expected in the LightStream 1010 ATM switch environment.
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.
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:
access-list (extended)
access-list (standard)
