tag-switching atm control-vc
To configure the VPI and VCI to be used for the initial link to the Tag Switching peer device, use the tag-switching atm control-vc interface configuration command. The initial link is used to establish the TDP session and to carry non-IP traffic. To clear the interface configuration, use the no form of this command.

Usage Guidelines
This command first appeared in Cisco IOS Release 11.1 CT.
For a router interface (for example, an AIP) ATM Tag Switching can be enabled only on a tag-switch subinterface.
Note
The tag-switching atm control-vc and tag-switching atm vpi subinterface level configuration commands are available on any interface that can support ATM tagging.
On the Cisco LightStream 1010 ATM switch, a subinterface corresponds to a VP tunnel, so the VPI field of the control-vc must match the VPI field of the VP tunnel.
Example
The following creates a Tag Switching subinterface on a router and selects VPI 1 and VCI 34 as the control VC:
interface atm4/0.1 tag-switching
tag-switching ip
tag-switching atm control-vc 1 34
