can combine any two data ports. For example:
•
Data 1 and Data 2
•
Data 3 and Data 4
•
Data 2 and Data 3
•
etc.
Some Cisco appliances contain a fiber optic network interface option. If available, you will see two
additional ethernet interfaces (Data 3 and Data 4) in the list of available interfaces on these appliances.
These gigabit fiber optic interfaces can be paired with the copper (Data 1, Data 2, and Management)
interfaces in a heterogeneous configuration.
