Description (partial)

subdb_svr crash after modifying User Profile in RADIUS

a.	As part of pppoe subscriber bring up, User Profile is downloaded from RADIUS after successful authentication of subscriber.

b.	User profile attributes are of 2 types.
•	Simple/single value attributes
-	Service-Type = Framed-User 
•	Multi value attributes
PQoS_5Mbps_OUT         Cleartext-Password := "cisco"
                cisco-avpair += "ip:qos-policy-out=add-class(sub,(class-default,BROADBAND_VOZ),police(1536,transmit,drop),pri-level(1),set-cos(5))",
                cisco-avpair += "ip:qos-policy-out=add-class(sub,(class-default,BROADBAND_CRITICOS),bw-rpct(50),set-cos(1))",
                cisco-avpair += "ip:qos-policy-out=add-class(sub,(class-default,BROADBAND_BUSINESS),bw-rpct(35),set-cos(1))",
                cisco-avpair += "ip:qos-policy-out=add-class(sub,(class-default,class-default),bw-rpct(15),set-cos(0))",
                cisco-avpair += "ip:qos-policy-out=add-class(sub,(class-default),shape(5324))"

c.	All the downloaded attributes will be converted, encoded into sysdb format and installed in subdb_svr so that relevant config can be available for subdb clients like  qos_ma, ppp_ma, ipv4_ma etc.

d.	As part of CSCup20620, a subdb internal error case is missed (as part of implementation) while installing multivalued attribute (a.k.a. qos).

e.	As part of CSCur17509, error case mentioned in step-d is handled properly.
