3Com Switch 8800 Configuration Guide
After the terminal service is disabled on a user interface, you cannot log in to the switch
through the user interface. However, the user logged in through the user interface
before disabling the terminal service can continue his operation. After such user logs
out, he cannot log in again. In this case, a user can log in to the switch through the user
interface only when the terminal service is enabled again.
Table 4-8 Enable/disable terminal service
Enable terminal service
Disable terminal service
By default, terminal service is enabled on all the user interfaces.
Note the following points:
For the sake of security, the undo shell command can only be used on the user
interfaces other than Console user interface.
You cannot use this command on the user interface via which you log in.
You will be asked to confirm before using undo shell on any legal user interface.
II. Configuring idle-timeout
Table 4-9 Configure idle-timeout
Configure idle-timeout
Restore the default idle-timeout
By default, idle-timeout is enabled and set to 10 minutes on all the user interfaces. That
is, the user interface will be disconnected automatically after 10 minutes without any
operation.
idle-timeout 0 means disabling idle-timeout.
III. Locking user interface
This configuration is to lock the current user interface and prompt the user to enter the
password. This makes it impossible for others to operate in the interface after the user
leaves.
