5.3.2. The Port Passwords
The Port Passwords (or User Passwords) allow system
administrators to restrict access to a specific group of ports.
When the APS-8M command mode is accessed with a Port
Password, users may only connect to the RS232 Ports to which
they have been granted access, and review configuration
parameters for those ports. Port Passwords do not grant access
to APS-8M configuration commands.
The configuration menus (/P) for each RS232 port allow a Port
Password to be assigned to each individual port. In order to
allow a Port Password to grant access to a group of APS-8M
ports, the same Port Password is assigned to each port in the
group.
For example, if the Port Password “test” is assigned to ports 3, 4,
and 5, then when “test” is entered at the Password Prompt, the
user will only be able to connect to ports 3, 4, and 5, and will
only be able to view parameters for ports 3, 4, and 5.
If desired, all APS-8M ports can function as both a Supervisor
Port and a User Port, depending on which password is entered at
the login prompt. However, if you wish to prevent a port from
being able to access the Supervisor Mode at all (even with the
Supervisor Password), the Supervisor Mode can be disabled at
the RS232 Ports using the Port Configuration menus as described
in Section 5.5. Note however, that the Supervisor Mode cannot
be disabled at Ports 1 and 2; these ports are designated as SetUp
Ports, and are always allowed password protected access to
Supervisor Level commands.
Note: When Port Passwords are defined, the
APS-8M will not allow you to select a Port Password
that has already been used as the Supervisor
Password.
