Notes:
1. To target a subscriber host in a retail service it is mandatory to include the [26-6527-17] Alc-Retail-
Serv-Id attribute. Omitting this attribute results in a CoA NAK with [101] Error-Cause attribute value 
503 (Session Context Not Found).
2. Although a single host is identified, the CoA or Disconnect Message will apply to all hosts of a dual 
stack PPPoE session or IPoE session (if enabled).
