Interface
Parameters
Egress
Bandwidth
Enter the maximum amount of traffic, in kilobits per second, the NXC can send through
the interface to the network. Allowed values are 0 - 1048576.
Ingress
Bandwidth
This is reserved for future use.
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 576 - 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.
