Chapter 7 Advanced Network Configuration
NIC pairing is not available on C1x appliances or M-Series appliances. Some C3x, C6x, and X10x
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.

NIC Pairing and VLANs
VLANs (see
) are only allowed on the primary
interface.
NIC Pair Naming
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.
Configuring and Testing NIC Pairing/Teaming
Once you have verified your ethernet media setting, use the
etherconfig
command to configure NIC
pairing. You will be prompted for a name to use to refer to the pair.
The
failover
sub-command switches the active interface. The system will not automatically switch
back to the primary NIC when it comes back on line and the backup interface will remain active in that
case until you explicitly switch the system back over to the primary NIC (by using the
case until you explicitly switch the system back over to the primary NIC (by using the
failover
command) or unless the backup NIC has a failure. See
.
Use the
delete
subcommand to remove NIC pairs.
When configuring NIC pairing, keep in mind that all configuration changes require a commit, except for
failover
. The
failover
command force a failover during the next polling interval which is every 15
seconds once NIC pairing configuration has been committed.
NIC Pairing and Existing Listeners
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.
