The device CR16K serves as a BRAS, originally configured with static sessions on interface 808.

interface Route-Aggregation1.808

 ip subscriber session static ip 172.X.X.X 172.Y.Y.Y

After some time, changes are required, and an error occurs when deleting the static sessions.

undo ip subscriber session static ip 172.X.X.X 172.Y.Y.Y

Operation failed. Cannot delete or modify static session configuration because online static users exist.

Static session entries must be deleted before this command can be removed.

The old version uses the command reset ip subscriber session for deletion.

For on-site devices running version 8530Pxx, the new version does not have this command but allows usingcut access-userDelete user session:
