922CHAPTER 70: TERMINAL ACCESS CONFIGURATION COMMANDS

VTYs and each VTY corresponds to one application. When multiple VTYs are configured on a terminal with the corresponding switching hotkeys, you can press the switching hotkeys to quickly switch between the VTYs without making any selection on the menu. The connection of the original VTY application is not torn down. This way, dynamic switching between the VTYs (namely, different applications) on a terminal is implemented.

Note that the ASCII value of the hotkey configured must be different from that of any other hotkey configured on the device. Otherwise, hotkey conflicts will occur. For example, the hotkey value cannot be set to 17 or 19 because these two values are used for the hotkeys of flow control. Using a hotkey may not get a response rapidly when the terminal displays too much data.

Example # Configure the hotkey for VTY 1 as <Ctrl+A>, namely, 1.

<Sysname> system-view

[Sysname] rta template abc

[Sysname-rta-template-abc] vty 1 hotkey 1

vty password

Syntax vty vty-numberpassword { simple cipher } string

undo vty vty-numberpassword

View Terminal template view

Parameters vty-number: VTY number, ranging 0 to 7.

simple: Uses a plaint-text password that is displayed in plain text.

cipher: Uses a ciphertext password that is displayed in ciphertext.

string: Password. It is a plain-text string of 1 to 16 characters or a ciphertext string of 24 characters.

Description Use the vty password command to configure the password for VTY authentication.

Use the undo vty password command to cancel the password configured.

By default, no password is configured for VTY authentication.

Note that this command takes effect in RTC terminal access only and is used by the RTC server to authenticate RTC clients. To support terminal access authentication, passwords must be configured on the RTC server and the RTC clients, and authentication succeeds only if the passwords are the same. If authentication is not to be implemented, make sure no password is configured on the RTC server or any RTC client.

Example # Configure the authentication password for VTY 1 as abc.
