Router Redundancy
Router Redundancy enables SPECTRUM to contact the device through an
alternate port in the event of a primary port failure.
If SPECTRUM is unable to contact the router through the IP address initially
assigned to it (Primary Address), the routerÕs icon turns yellow, and
SPECTRUM attempts to reach the router via the ports on the deviceÕs
Preferred Address list, until contact is made. SPECTRUM then uses that IP
address to obtain network management information from the router until the
Primary Address becomes available again. When contact is re-established
through the Primary Address, the icon turns green.
If SPECTRUM is unable to make contact via any of the Preferred Addresses,
the routerÕs icon turns red, denoting that contact has been lost with the actual
physical device.
