To display a list of all available interfaces known to the system you can use the
ifstat command.
There are three types of interfaces available on the bintec router, the first of
which is always available. The other interface types will depend on your partic-
ular configuration.
■
Local interface
The local interface is a special interface and is always available on the bin-
tec router.
■
Point-to-point interface
This interface type includes ISDN dialup, ISDN leased lines, serial and X.31
interfaces.
■
Point-to-multipoint interface
This interface type includes LAN connections over LLC2.
1.1.2 Point-to-Point and Point-to-Multipoint Inter-
faces
One of the characteristics of an X.25 interface that must be defined is the en-
capsulation used.
When creating X.25 point-to-point interfaces in the W
you can specify either x25 or x25_ppp encapsulation. By default, x25 encapsu-
lation is used. This allows an interface to be used solely for X.25 traffic. Using
x25_ppp allows PPP and X.25 traffic to be routed over the same interface (i.e.
multiplexing IP datagrams and X.25 packets simultaneously over the same
ISDN channel).
For X.25 point-to-multipoint interfaces, such as Ethernet, you must use the
enx-y-llc interfaces, since not all Ethernet interfaces on the bintec router support
X.25 (i.e. enx-y, enx-y-snap, and enx-y-nov802.3 with x= slot and y= unit.)
