Default Route If enabled, the PPPoE interface will be configured as the
default route for any IP traffic to an address matching no
other configured route.
Default Metric The metric of a network route is a property used by a
routing protocol to determine whether one particular route
should be chosen over another.
In conflicting cases, traffic will be directed towards the
gateway containing the lowest value metric.
3.2.4 X.21 Interface configuration
If the Com.X is equipped with an X.21 serial interface (typically for connection to
leased line or frame relay services), the interface is listed as serial0 (X21-1) in the
Interfaces list.
The Com.X X.21 interface is always DTE on the physical layer (although it may act
as protocol DCE in Frame Relay mode). Therefore, the clock and thus the data rate
of the interface is provided by the DCE equipment connected to the X.21 interface,
typically an NTU.

As with other network interfaces, the interface configuration may be edited by double-
clicking the list entry. The availability of the different fields will depend on the Serial
Protocol chosen.
