Cisco Cisco Email Security Appliance C190 ユーザーガイド

The following information is required when you configure an IP interface:

If you have completed the GUI’s System Setup Wizard (or the Command Line 
Interface 

systemsetup

 command) as described in 

 and committed the changes, one or two interfaces should already be 

configured on your appliance. (Refer to the settings you entered in the “Assign 
and Configure Logical IP Interface(s)” section.) In addition, the Management 
interface is configured on the Cisco IronPort appliance.

The nickname of the interface. 

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

You can enter the netmask in standard dotted octet 
form (e.g. 255.255.255.0) or hexadecimal form (e.g. 
0xffffff00). The default netmask is 255.255.255.0, a 
common class C value. 

Cisco IronPort AsyncOS automatically calculates 
the default broadcast address from the IP address and 
the netmask. 

The hostname that is related to the interface. This 
hostname will be used to identify the server during 
the SMTP conversation. You are responsible for 
entering a valid hostname associated with each IP 
address. The software does not check that DNS 
correctly resolves the hostname to the matching IP 
address, or that reverse DNS resolves to the given 
hostname. 

FTP, SSH, Telnet, IronPort Spam Quarantine, HTTP, 
and HTTPS can be enabled or disabled on the 
interface. You can configure the port for each 
service. You can also specify the HTTP/HTTPS, 
port, and URL for the IronPort Spam Quarantine.
