Cisco Cisco Email Security Appliance C170 Guia Do Utilizador

You can create more than one NIC pair, providing you have enough data ports. When creating pairs, you 
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.

VLANs (see 

) are only allowed on the primary 

interface.

When creating NIC pairs, you must specify a name to use to refer to the pair. NIC pairs created in 
versions of AsyncOS prior to version 4.5 will automatically receive the default name of ‘Pair 1’ 
following an upgrade.

Any alerts generated regarding NIC pairing will reference the specific NIC pair by name.

If you enable NIC pairing on an interface that has listeners assigned to it, you are prompted to either 
delete, reassign, or disable all listeners assigned to the backup interface. 

NIC pairing is not available on Email Security virtual appliances.
