Cisco Cisco Email Security Appliance C170 Guia Do Utilizador

This chapter includes information about advanced network configuration generally available via the 

etherconfig

 command, such as NIC pairing, VLANs, Direct Server Return, and more. This chapter 

contains the following sections:

Media settings for the ethernet interfaces can be accessed via the use of the 

etherconfig

 command. Each 

ethernet interface is listed with its current setting. By selecting the interface, the possible media settings 
are displayed. See 

 for an example.

The 

etherconfig

 command can be used to set the duplex settings (full/half) as well as the speed 

(10/100/1000 Mbps) of ethernet interfaces. By default, interfaces automatically select the media 
settings; however, in some cases you may wish to override this setting. 

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

systemsetup

 

command) as described in the “Setup and Installation” chapter of the Cisco IronPort AsyncOS for Email 
Configuration Guide and committed the changes, the default ethernet interface settings should already 
be configured on your appliance.

Some Cisco IronPort C3x, C6x, and X10x appliances contain a fiber optic network interface option. If 
available, you will see two additional ethernet interfaces (Data 3 and Data 4) in the list of available 
interfaces on these appliances. These gigabit fiber optic interfaces can be paired with the copper (Data 
1, Data 2, and Management) interfaces in a heterogeneous configuration. See
