Using the System Setup Wizard
Assign and Configure Logical IP Interface(s)
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.

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.

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.
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.
Note
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.
one Ethernet port for your private network and the other for the public network, you may want to
name them PrivateNet and PublicNet, respectively.
Note
The names you define for interfaces are case-sensitive. AsyncOS will not allow you to create two
identical interface names. For example, the names
identical interface names. For example, the names
Privatenet
and
PrivateNet
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.
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.
Note
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.
Note
For C170 and C190 appliances, the Data 2 interface is configured first.
Specify the Default Gateway
In the next portion of the
systemsetup
command, you type the IP address of the default router (gateway)
on your network.
