Description Use the
x25 switch svc command to configure an SVC (switching virtual circuit),
indicating the packet to be forwarded to the destination address through the
specified interface.
Use the
undo x25 switch svc command to delete the SVC route.
A device with X.25 switching configured can act as a simple X.25 switch.
The output interface of the SVC switching can be an X.25 interface, or FR
interface Annex G DLCI. The link layer of the output interface must be X.25, or FR
with the Annex G DLCI configured for output.
Before using this command, you should use the x25 switching command to
enable X.25 switching.
By default, no SVC is defined.
