RADIUS CoA and Disconnect Message Attributes
Subscriber Host Identification Attributes
Table 76 details the different attributes that can be used in a CoA and Disconnect Message to
identify one or multiple subscriber host(s).
(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).
(3) Maximum 32 hosts can be targeted in a single CoA or Disconnect Message. When more than 32
hosts are identified, the CoA and Disconnect Message is rejected with [101] Error-Cause attri-
bute value 501 (Administratively Prohibited).
