Chapter 1 Introduction to the ASA 5580 Specifications Interface Numbering Interfaces are named interface_type slot/port. • The expansion slot numbers are 1 through 9, and increase from right to left. Slot 0 is used for the built-in Management interfaces. Slots 1, 2, and 9 are reserved. • On a network interface adapter, the interfaces are numbered from 0 through 3 (depending on the number of interfaces on the adapter) from the top to the bottom. For example, for a Gigabit Ethernet adapter installed in slot 3, the second interface from the top is called: GigabitEthernet 3/1 For a 10-Gigabit Ethernet adapter in slot 7, the top interface is called: TenGigabitEthernet 7/0 Auto-MDI/MDIX Feature For RJ-45 interfaces, the default auto-negotiation setting also includes the Auto-MDI/MDIX feature. Auto-MDI/MDIX eliminates the need for crossover cabling by performing an internal crossover when a straight cable is detected during the auto-negotiation phase. Either the speed or duplex must be set to auto-negotiate to enable Auto-MDI/MDIX for the interface. If you explicitly set both the speed and duplex to a fixed value, thus disabling auto-negotiation for both settings, then Auto-MDI/MDIX is also disabled. For Gigabit Ethernet, when the speed and duplex are set to 1000 and full, then the interface always auto-negotiates; therefore Auto-MDI/MDIX is always enabled and you cannot disable it.
