NIC Pairing and VLANs NIC Pair Naming 7-4 Cisco IronPort AsyncOS 7.6 for Email Advanced Configuration Guide 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. VLANs (see Virtual Local Area Networks (VLANs), page 7-8) 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. Configuring and Testing NIC Pairing/Teaming NIC Pairing and Existing Listeners 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 failover command) or unless the backup NIC has a failure. See Using the failover Subcommand for NIC Pairing, page 7-6. 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. 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. OL-25137-01

If you continue, the Data 2 interface will be deleted. Do you want to continue? [N]> y The interface you are deleting is currently used by listener "OutgoingMail". What would you like to do? 1. Delete: Remove the listener and all its settings. 2. Change: Choose a new interface. 3. Ignore: Leave the listener configured for interface "Data 2" (the listener will be disabled until you add a new interface named "Data 2" or edit the listener's settings).
