Network Protocol
The transport mechanism for voice packets.
Ethernet only: All communications are at the Ethernet frame
layer.
Standard IP: IP communications are used for traffic between
NBX system addresses.
IP On-the-Fly: An implementation of IP communications in
which Layer 2 (Ethernet) devices are temporarily assigned a
Layer 3 (IP) address only when they need to communicate with
a Layer 3 device on a different subnetwork. The IP address is
assigned from an address pool defined by the NBX system
administrator. After the Layer 2 device returns to the idle state
the IP address is returned to the pool of available addresses for
future use.
If you select IP On-the-Fly in the Network Protocol list, you
must return to the Current System Settings window, select IP
Addresses and add the IP addresses associated with IP
On-the-Fly. There may be unpredictable results in other system
functions if you have Network Protocol set to IP On-the-Fly but
do not have any IP addresses.
