DESCRIPTION
This field is enabled if you select Use Fixed IP Address.
Enter the IP address of the gateway. The NXC sends packets to the gateway when it
does not know how to route the packet to its destination. The gateway should be on the
same network as the interface.
This field is enabled if you set the Interface Type to external or general and select
Get Automatically.
Enter the priority of the gateway (if any) on this interface. The NXC decides which
gateway to use based on this priority. The lower the number, the higher the priority. If
two or more gateways have the same priority, the NXC uses the one that was
configured first.
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.
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.
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.
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.
Select this to turn on the connection check.
Select the method that the gateway allows.
Select icmp to have the NXC regularly ping the gateway you specify to make sure it is
still available.
Select tcp to have the NXC regularly perform a TCP handshake with the gateway you
specify to make sure it is still available.
Enter the number of seconds between connection check attempts.
Enter the number of seconds to wait for a response before the attempt is a failure.
Enter the number of consecutive failures before the NXC stops routing through the
gateway.
Select this to use the default gateway for the connectivity check.
Select this to specify a domain name or IP address for the connectivity check. Enter
that domain name or IP address in the field next to it.
This field only displays when you set the Check Method to tcp. Specify the port
number to use for a TCP connectivity check.
These fields appear when you set the Interface Type to Internal or General.
