Configuration Task List for Physical Interfaces
By default, all interfaces are operationally disabled and traffic will not pass through them.
The following section includes information about optional configurations for physical interfaces:
• Overview of Layer Modes
• Configure Layer 2 (Data Link) Mode
• Management Interfaces
• Auto-Negotiation on Ethernet Interfaces
• Adjust the keepalive timer
• Clear interface counters
FTOS Behavior: S-Series systems use a single MAC address for all physical interfaces while
E-Series and C-Series use a unique MAC address for each physical interface, though this results in no
functional difference between these platforms.
