Ethernet Interfaces
The Cisco IronPort X1050/1060/1070, C650/660/670, and C350/360/370 appliances are equipped with
as many as four Ethernet interfaces located on the rear panel of the system depending on the
configuration (whether or not you have the optional optical network interface). They are labeled:

Selecting IP Addresses and Netmasks
When you configure the network, the Cisco IronPort appliance must be able to uniquely select an
interface to send an outgoing packet. This requirement will drive some of the decisions regarding IP
address and netmask selection for the Ethernet interfaces. The rule is that only one interface can be on
a single network (as determined through the applications of netmasks to the IP addresses of the
interfaces).
