General consensus is: D in the aggregation facing Downstream, U in the CPE facing Upstream. This is also confirmed by Cisco documentation.

Thanks for the input. -- Tim:> _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
