Cisco Cisco Email Security Appliance C160 Mode D'Emploi

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, an 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.
