Enter the maximum amount of traffic, in kilobits per second, the NXC can receive from the
network through the interface. Allowed values are 0 - 1048576.
MTU Maximum Transmission Unit. Type the maximum size of each data packet, in bytes, that can
move through this interface. If a larger packet arrives, the NXC divides it into smaller
fragments. Allowed values are 1280 - 1500. Usually, this value is 1500.
Connectivity Check These fields appear when you set the Interface Type to External or General.
The interface can regularly check the connection to the gateway you specified to make
sure it is still available. You specify how often the interface checks the connection, how long
to wait for a response before the attempt is a failure, and how many consecutive failures
are required before the NXC stops routing to the gateway. The NXC resumes routing to the
gateway the first time the gateway passes the connectivity check.
