Web / command line interface
The router can be configured using several different methods. This section describes how to
configure the web GUI and CLI (command line interface) options.
Automatically log user out if idle for h hours m minutes s seconds
To limit the probability of unauthorized users gaining access to the router, login timeouts are
applied. These timeouts cause an existing connection to be closed after a predefined period.
The default is 20 minutes.
For users connected on the local Async port
Use access level None, Low, Med, High, Super
For security purposes, logging into the router is controlled by a user access level. This
parameter controls the access level that applies when logging in via the local asynchronous
serial port.
Automatically log user out Never / If idle for h hrs m mins s secs
How long the local port allows access before terminating the connection and requiring the
user to log in again. Selecting the Never buttons allows permanent access to the router via
the local asynchronous serial port. If, for security reasons, it is required that the access should
be limited, the appropriate time period can be entered into the text entry boxes.
Disable Remote command echo for Telnet sessions
Enables/disables command echo for remote access. This applies to Telnet and TRANSIP
sessions.
CLI Pre-Login Banner
The router can display a banner before any login information is requested. The parameter
specifies the name of a file that is stored in the flash filing system and contains the text to be
displayed before the request for the username and password. This can be useful for
displaying a standard welcome message or any site-specific user instructions.
