cannot map new DLCI

[Refaat M. Saadi]

Dear all,   I'm trying to configure my router to have a new DLCI on one of the sub interfaces. When trying to map that DLCI on "int ser 1/0.x" with DLCI number xyz I receive the error "DLCI xyz is already assigned to int ser 1/0" Using the show frame-relay map doesn't show if there is DLCI xyz assigned to any interface...... I tried to use "Show frame-relay pvc xyz" command, that didn't show any thing, as if that DLCI is not there at all.... What could be the problem?   Best regards, ref
