by this option.

NOTE: The effective access level is always the lowest one assigned to either the port
or the user. For example, if the Port Access Level assigned is Level-2, but the User
Access Level is Level-3, then only Level-3 access is permitted for the port.
Level-1 – Allows full access and control of the device, including monitoring, diagnostics,
and configuration. The user can add, change, and display configuration options and
perform device testing.
CAUTION: Before changing the communication port’s access level to Level-2 or
Level-3, make sure that the Telnet Session Access Level is set to Level-1 and at least
one Login ID is set to Level-1. Otherwise, access will be lost. If this occurs, you must
reset the unit to the factory defaults and begin the configuration process again.
Level-2 – User limited to display status, run tests, and view configuration option settings.
Level-3 – User limited to display status and view configuration screens only.
