40 CHAPTER 1: USING SYSTEM ACCESS COMMANDS Description Use the shell command to enable the terminal service for a user interface. The terminal service is enabled by default. Use the undo shell command to disable the terminal service for a user interface. When using the undo shell command, note the following points. ■ For reasons of security, the undo shell command can only be used on user interfaces other than the AUX user interface. ■ You cannot use this command on the current user interface. ■ You are asked to confirm the command. Example To disable the terminal service on the VTY user interfaces 0 to 4, enter the following from another user interface: system-view System View: return to User View with Ctrl+Z. [SW5500]user-interface vty 0 4 [SW5500-ui-vty0-4]undo shell speed Syntax speed speed-value undo speed View User interface view Parameter speed-value: Specify the transmission rate on the AUX (Console) port in bits per second (bps). This can be any of the following values: 1200, 2400, 4800, 9600, 19200, 38400, 57600, or 115200 . The default rate is 19200 bps. Description Use the speed command to configure the transmission rate on the AUX (Console) port. Use the undo speed command to restore the default rate. This command can only be performed in AUX user interface view. Example To configure the transmission speed on the AUX (Console) port as 9600 b/s, enter the following: system-view System View: return to User View with Ctrl+Z.
