Cisco Cisco Email Security Appliance C160 Mode D'Emploi

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

etherconfig

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

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 and committed the changes, the default 
ethernet interface settings should already be configured on your appliance.

Some 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
