[c-nsp] DHCPv6 accounting on ASR1000

[Christian Schmit]

Hi,
  
 I am trying to setup DHCPv6 accounting to sent start/stop records to a 
radius server however without success so far. TAC told me that apparently 
in IOS XE 3.13 this would be working but not in any previous version like 
IOS XE 3.7.x or 3.10.x according to their tests. We are currently on IOS XE 
3.7.5 for our testing. The TAC engineer however cannot find any known bug 
or information describing this issue.
  
 below is the config I tested:
   
 aaa accounting delay-start all
aaa accounting update periodic 120
aaa accounting network default start-stop group radius
aaa accounting network RADIUS-GROUP1 start-stop group radius
 !
 ipv6 dhcp pool SRV-P1
 prefix-delegation pool IPV6-P1 lifetime 86400 86400
 dns-server x.x.x.x.x.x.x.x

 Is anyone running dhcpv6 accounting successfully on the ASR1k? If yes 
under which IOS XE version?
  
 regards,
 Christian
