ANCP port up message received from DSLAM is wrongly interpreted by ASR1k. ASR1k creates therefore a RADIUS attribute type unknown.

  VSA: l=122 t=unknown-Attribute (201): 009100040000000300810004000000000082000400000000......

Conditions:
different ANCP implementation standards on DSLAM as on Router.
DSLAM with ANCP implementation based on Wadhwa-Draft from 27-DEC 2005
Router with ANCP implmentation based on Wadhwa-Draft from 25-FEB 2007
