Alc-AA-App-
Service-Options
Used to apply Application Service Option (ASO) overrides. These attributes
can only be applied if an app-profile is also or has previously been associated
with the AA-sub (explicitly or by default), or else the override is rejected. An
access accept or COA message can send one or more of these VSAs, with
each VSA containing a string with the characteristic name and the value name
pair. To provide multiple ASO attributes, the message can include multiple
ASO VSAs, in addition to an App-profile VSA.
The VSA string contains the characteristic name and the value name. The
format for the Alc-AA-App-Service-Options string must be "char=value". An
equal sign is used as the delimiter between characteristic string and value
string.
Each name can have any character including spaces, except ‘=’. Everything
before the '=' will be interpreted as the character string and everything after the
'=' will be interpreted as the value string. One ASO char=value pair is supported
per VSA, If an ASO char=value pair is not found in a VSA, the message is
rejected. If an ASO char=value does not match a provisioned ASO for the
group/partition for that subscriber, the message is rejected.
An app profile is a defined set of ASO values. App-profiles interact with ASO
overrides in this way:
• The Alc-AA-App-Service-Options VSA is optional on sub create
(with app-profile assignment) and may be used later to modify
policy.
• On a COA if an app-prof VSA is not present all ASO VSAs will be
applied on top of the current policy of the sub.
• On a COA if an app-prof VSA is present, even if it is the same app-
profile as currently applied, ll previous ASO override policy is
removed. Any ASO VSAs in the same COA message as the new
app-profile will be applied on top of the app-profile policy. In this
way, re-sending app-profile resets all ASO state history. On a COA,
if the app-profile changes, and no ASO VSAs exist, all current ASO
overrides are removed.
• If the app-profile changes, and ASO VSAs exist, all current ASO
overrides are removed, and the new ASO overrides are applied to
this new app-profile.
