The access that a user is allowed:

zAdmin—The admin level user has total access to the Device Server. You can create more than one admin user account but we recommend that you only have one. They can monitor or configure the Device Server through the CLI or Menu.

zNormal—The Normal level user has limited access to the Device Server. Limited CLI commands and Menu access are available with the ability to configure the user’s own configuration settings.

zRestricted—The Restricted level user can only access predefined sessions or access the Easy Port Access menu. Can only view or monitor the Device Server using CLI commands to display information about the Device Server.

zMenu—The menu level user will only be able to access predefined session or access the Easy Port Access menu. The Easy Port Access allows the user to connect to the accessible line without disconnecting their initial connection to the Device Server. Does not have any access to CLI commands.

The prefix that a user types to control the current session. The default value is hex 01, which corresponds to Ctrl-a(^a) (hex value 02 would be Ctrl-b (^b), etc.):

z^a number—To switch from one session to another, press ^a and then the required session number. For example, ^a 2 would switch you to session 2. Pressing ^a 0 will return you to the Device Server Menu.

z^a n—Display the next session. The current session will remain active. The lowest numbered active session will be displayed.

z^a p—Display the previous session. The current session will remain active. The highest numbered active session will be displayed.

z^a m—To exit a session and return to the Device Server. You will be returned to where you left off. The session will be left running.

z^a l—(Lowercase L) Locks the line until the user unlocks it. The user is prompted for a password (any password, excluding spaces) and locks the line. Next, the user must retype the password to unlock the line.

z^r—When you switch from a session back to the Menu, the screen may not be redrawn correctly. If this happens, use this command to redraw it properly.

The User Hotkey Prefix value overrides the Line Hotkey Prefix value. You can use the Hotkey Prefix keys to lock a line only when the line Lock parameter is On.

The amount of time, in seconds, that the idle timer will run. Use this timer to close a connection because of inactivity. When the idle timer expires, because there has been no exchange of data within the specified time, the Device Server will close the connection. The default value is 0 (zero), meaning that the idle timer will not expire (the connection is open permanently). The maximum value is 4294967 seconds. The User Idle Timer will override the Line Idle Timer, with the exception reverse Telnet sessions.

The amount of time, in seconds, that the session timer will run. Use this timer to forcibly close a user’s session (connection). When the session timer expires, the Device Server will end the connection. The default value is 0 (zero), meaning that the session timer will not expire (the session is open permanently, or until the user logs out). The maximum value is 4294967 seconds. The User Session Timer will override the Line Session Timer, with the exception of reverse Telnet sessions.
