Interface link up not detected

If the firewall complains that it did not detect an interface link up event during automatic assignment, first make sure that the cable is unplugged and that the interface does not have a link light prior to choosing the link detection option. After selecting the option, plug the cable back into the interface and ensure it has a link light prior to pressing Enter. Test or replace the cable in question if it does not show a link light on the switch and/or NIC port once it is connected.

If a network cable is connected directly between two computers and not to a switch, and one of those pieces of hardware is older (e.g. 10/100 NIC) ensure that a crossover cable is being used. Gigabit adapters all support Auto-MDIX and will handle this internally, but many older 10/100 adapters do not. Similarly, if connecting a firewall running AZTCO-FW software to a switch that does not support Auto-MDIX, use a straight-through patch cable.

If the interface is properly connected but the firewall still does not detect the link event, the network interface may not properly detect or report link status to the operating system or driver. In this case, manually assigning the interfaces is necessary.
