This option specifies the network interface CDRouter will use as its primary WAN test interface. This interface must be physically connected to the DUT’s WAN interface. Any Ethernet, wireless or ATM PVC network interface that is properly installed in the Linux host system may be used.
Note that all network interfaces used by CDRouter must be configured with a static IP address of 0.0.0.0 in the Linux host system. CDRouter will automatically configure the IP addresses of all test interfaces based on the configuration options specified here. Please see this Knowledge Base article for more information.
ATM PVC interface names must be specified using the following notation and VPI must be set to zero. For example, if there is only one ATM card and the PVC is connected on VPI = 0, VCI = 32, the interface should be configured as 0.0.32.
<ATM card number>.<VPI>.<VCI>
