Hi Alfred,We won't have this on ASR901's radar, and in fact we implemented error message mechanism to alert ourcustomers.  Its a ASIC and feature limitation on ASR901 alone.  Cheers,/Mani

Hi Alfred,We don't support xconnect with ASR901 on SVI.  In fact we implemented the CLI error message while attempting to do so.  We support on EVC and port only.Cheers,/Mani
