IMPORTANT:
To avoid packet loss, make sure the speed of the AUX port is slower than the transmission rate of the
modem.
You can connect a device (Device B) to the AUX port of the current device (Device A), and configure the
current device to redirect a Telnet login user to that device. If the redirect enable and redirect listen-port
port-number commands are configured, a user can use the telnet DeviceA-IP-address port-number
command to log in to Device B. If the ip alias ip-address port-number command is also configured to
associate Device A's IP address with the Telnet redirect listening port, a user can use the telnet
DeviceA-IP-address command to log in to Device B. This Telnet redirect function enables a device to
provide Telnet service with its IP address protected.
To configure common AUX user interface settings for modem dial-in accesses:

Command Remarks
1. Enter system view.
system-view N/A
2. Enable copyright information
display.
copyright-info enable
By default, copyright information
display is enabled.
3. Associate the Telnet redirect
listening port with an IP
address of the current device.
ip alias ip-address port-number
By default, a Telnet redirect listening
port is not associated with any IP
address.
4. Enter one or more AUX user
interface views.
user-interface aux first-number
[ last-number ]

5. Configure the baud rate.
speed speed-value
By default, the baud rate is 9600
bps.
6. Configure the parity check
mode.
parity { even | mark | none | odd
| space }
The default setting is none, namely,
no parity check.
7. Configure the number of stop
bits.
stopbits { 1 | 1.5 | 2 }
The default is 1.
Stop bits indicate the end of a
character. The more the bits, the
slower the transmission.
8. Configure the number of data
bits in each character.
databits { 5 | 6 | 7 | 8 }
By default, the number of data bits in
each character is 8.
The setting depends on the
character coding type. For example,
you can set it to 7 if standard ASCII
characters are to be sent, and set it
to 8 if extended ASCII characters
are to be sent.
9. Define a shortcut key for
starting a session.
activation-key character
By default, press Enter to start a
session.
10. Define a shortcut key for
terminating tasks.
escape-key { default | character }
By default, press Ctrl+C to terminate
a task.
