[c-nsp] Problem with NTP synchronization

[Jens S Andersen]

Hi list

I'm having problems with ntp after upgrading one Cat6000/Sup2T to 
IOS  15.1(1)SY


After the upgrade it will no longer allow ntp clients to synchronize.

The ntp  access-lists have not changed.

ntp access-group peer 5
ntp access-group serve-only 6

If i remove the ntp access-groups, client syncs works again.

The configuration works fine on a Sup2T with IOS 15.0(1)SY1


15.1 runs ntpv4:
 
sh ntp information
Ntp Software Name       :  Cisco-ntpv4
Ntp Software Version    :  Cisco-ntpv4-1.0
Ntp Software Vendor     :  CISCO
Ntp System Type         :  Cisco IOS / M8572


Can sombody on the list explain whats going on?
