You should verify that NIC pairing is working correctly. To do so:

Use the 

ping

 command in the CLI to test your paired interface by “pinging” an IP address on the same 

subnet as the NIC pair that has been confirmed to return a ping by an independent source.:

Issue a failover command (

etherconfig -> pairing -> failover

). Wait 15 seconds.

Use the 

ping

 command in the CLI to test your paired interface again with the backup NIC as the active 

interface.

Finally, return the NIC pair to its default state by issuing one more failover so that the primary interface 
is now active.

VLANs are virtual local area networks bound to physical data ports. You can configure VLANs to 
increase the number of networks the Cisco IronPort appliance can connect to beyond the number of 
physical interfaces included. For example, a Cisco IronPort C6x appliance has three interfaces: Data 1, 
Data 2, and Management. VLANs allow more networks to be defined on separate “ports” on existing 
listeners. (See 

 for more information.) You can configure 

multiple VLANs on any physical network port. 

 provides an example of configuring several 

VLANs on the Data 2 interface.
