7750 SR RADIUS Attributes Reference Guide
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:
a) The Alc-AA-App-Service-Options VSA is optional on sub create (with
app-profile assignment) and may be used later to modify policy.
b) 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.
c) 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.
d) 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.
e) A new aa-sub characteristic can be applied, or an existing characteristic
modified, by an ASO VSA.
f) When a ASO VSA is received any existing overrides will remain and the
new overrides are cumulative.
If there are multiple ASO VSAs for the same characteristic in the COA, the
last one will take effect.
