Cisco Cisco Email Security Appliance C160 Mode D'Emploi

The next step assigns and configures a logical IP interface on the physical Ethernet interface named 
Management (on C370, C670, X1070, C380, C680, C390, and C690 appliances) or Data 1 (on C170 and 
C190 appliances), and then prompts you to configure a logical IP interface on any other physical 
Ethernet interfaces available on the appliance. 

Each Ethernet interface can have multiple IP interfaces assigned to it. An IP interface is a logical 
construct that associates an IP address and hostname with a physical Ethernet interface. If you decided 
to use both the Data 1 and Data 2 Ethernet ports, you need the IP addresses and hostnames for both 
connections.

For C370, C670, X1070, C380, C680, C390, and C690 appliances: Cisco recommends using one of 
the physical Ethernet ports to connect directly to the Internet for the purposes of receiving inbound email 
through public listeners, and using another physical Ethernet port to connect directly to your internal 
network for the purposes of relaying outbound email through private listeners. 

For C170 and C190 appliances: By default, the 

systemsetup

 command will configure only one 

physical Ethernet port with one listener for receiving inbound email and relaying outbound email. 

When you configure an interface to relay outbound mail, the system turns on SSH for the interface as 
long as no public listeners are configured to use the interface. 

The following information is required:

A name (nickname) created by you to refer to the IP interface later. For example, if you are using 
one Ethernet port for your private network and the other for the public network, you may want to 
name them PrivateNet and PublicNet, respectively.

The names you define for interfaces are case-sensitive. AsyncOS will not allow you to create two 
identical interface names. For example, the names 

 and 

 are considered as two 

different (unique) names. 

The IP address assigned by your network administrator. This is can be an IPv4 or IPv6 address, You 
can assign both types of IP addresses to a single IP interface.

The netmask of the interface. The netmask must be in CIDR format. For example, use 

/24

 for the 

255.255.255.0 subnet.

IP addresses within the same subnet cannot be configured on separate physical Ethernet interfaces. See 

for more detailed information on Network and IP 

Address configuration. 

For C170 and C190 appliances, the Data 2 interface is configured first.

In the next portion of the 

systemsetup

 command, you type the IP address of the default router (gateway) 

on your network.
