Configuring a frame relay local virtual circuit

On a DCE or NNI frame relay main interface or subinterface, you must manually create virtual circuits.

On a DTE main interface, you do not necessarily create virtual circuits manually because the device can automatically create virtual circuits according to the settings received from the DCE side. On a DTE subinterface, the virtual circuit must be manually created. When manually creating virtual circuits on a DTE interface, make sure their DLCIs are identical to those used on the DCE.

A virtual circuit number is unique on a physical interface.

If the DLCI of a PVC is changed on the DCE interface, you can perform one of the following operations to enable the DTE to relearn the correct address mappings as soon as possible:

Before doing that, make sure no services will be interrupted.
