Port Security Screening
Administrative Tasks
5. Choose the Apply button to create several screens in a single session, choosing the 
Set Defaults button to retrieve the default values if necessary. Otherwise, click OK 
to create the new screen and return to the Navis EMS-CBGX window. 
Assigning Security Screens to Logical Ports
Once you create the security screens, you must modify existing logical ports to assign 
these screens to the individual logical ports. The default security screens you 
configure for each logical port enable you to quickly pass or block incoming or 
outgoing SVCs, without having to remove or modify the screen you have applied. 
You also have the option of assigning several different security screens to this port, but 
configuring them as “inactive.” You can then activate them as necessary, at a later 
time.
