Chapter 6: Network Tab 
The Network tab allows you to configure settings for the 
management network. There are two ways to access the 
airFiber Configuration Interface:
•  Management Port  Enabled by default. Use a direct 
connection to the Management port for out-of-band 
management.
•  In-Band Management  Enabled by default. In-band 
management is available through the local Data port or 
the Data port at the other end of the link.
The Management port and in-band management share 
the default IP address of 192.168.1.20.
Change  To save or test your changes, click Change.
A new message appears. You have three options:
•  Apply  To immediately save your changes, click Apply.
•  Test  To try the changes without saving them, click Test. 
To keep the changes, click Apply. If you do not click 
Apply within 180 seconds (the countdown is displayed), 
the airFiberX radio times out and resumes its earlier 
configuration.
•  Discard  To cancel your changes, click Discard.
Management Network Settings
In-Band Management  Enabled by default. In-band 
management is available through the local Data port or 
the Data port at the other end of the link.
Note: If In-Band Management is enabled, ensure 
that each airFiberX radio in a link has a unique 
IP Address. If the airFiberX radios use the same IP 
Address, you may lose access via the Data ports.
Management IP Address  The airFiberX radio can use 
a static IP address or obtain an IP address from its DHCP 
server.
•  DHCP  Keep the default, DHCP, to use DHCP reservation 
on your router to assign a unique IP Address. The local 
DHCP server assigns a reserved IP address, gateway IP 
address, and DNS address to the airFiberX radio.
Note: If you select the DHCP option, ensure that 
you use DHCP reservation because if you do not 
know the IP address, then the only way to manage 
the airFiberX radio is to reset the airFiberX radio 
to its factory default settings. (Press and hold 
the Reset button for more than five seconds.) 
Its default Management IP Address is reset to 
192.168.1.20. 
 - DHCP Fallback IP  Specify the IP address the 
airFiberX radio should use if a DHCP server is not 
found.
 - DHCP Fallback Netmask  Specify the netmask the 
airFiberX radio should use if a DHCP server is not 
found.
•  Static  Assign static IP settings to the airFiberX radio.
Note: IP settings should be consistent with the 
address space of the airFiberX radio’s network 
segment.
