You can use the display user-interface command without any parameters to view supported user
interfaces and their absolute numbers.
Relative numbering
A relative number uniquely identifies a user interface among all user interfaces that are the same type in
the format user interface type + number, starting from 0 and incrementing by 1. For example, the first
console user interface is console 0.

Configuring asynchronous serial interface attributes
For users to Telnet to Device B from Device A, you can connect Device A to Device B through the
asynchronous serial interfaces, and configure the redirect enable and redirect listen-port port-number
commands on Device A. Then, users can use the telnet DeviceA's-IP-address port-number command to
log in to Device B. To facilitate the user login operation, you can associate the Telnet redirect listening
port with Device A's IP address by using the ip alias ip-address port-number command, so users only
need to enter telnet IP-address to log in to Device B.
To configure asynchronous attributes for a serial interface (AUX port or console port):
Step Command Remarks
1. Enter system view. system-view N/A
