OK - that's progress.

How about reducing it further.   Something like:

     qosType = "0"
     profileNb = "1      ;     # or whatever index you are using
     value = "rbQoSProfileType"

     oid = netsnmp.Varbind(value, profileNb, qosType)
     r = netsnmp.snmpget(oid, DestHost = "10.0.0.1", Community
="private", Version = 2)
     print ("Get1: %s")  %(r)

     oid = netsnmp.Varbind(value, profileNb, qosType)
     r = netsnmp.snmpset(oid, DestHost = "10.0.0.1", Community
="private", Version = 2)
     print ("Set: %s")  %(r)

     #oid = netsnmp.Varbind(value, profileNb, qosType)
     r = netsnmp.snmpget(oid, DestHost = "10.0.0.1", Community
="private", Version = 2)
     print ("Get2: %s")  %(r)


Does the initial GET crash?  Or is it just the GET *following* the SET request?
Does it make a difference if you uncomment the line that re-sets the
oid variable
befor the second GET?
