-number: SVC route number.

sub-destdestination-address: Replaces the destination X.121 address, an alphanumeric string of 1 to 15 characters. The system replaces the destination DTE address in the call request packet with the destination-address.

sub-sourcesource-address: Replaces the source X.121 address, an alphanumeric string of 1 to 15 characters. The system replaces the source DTE address in the call request packet with the source-address.

interface interface-typeinterface-number: Interface type and interface number.

dlci dlci-number: Specifies an DLCI. The dlci-numberargument is in the range 16 to 1007.

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.
