Much appreciated Tony! - Assume that the "oam-pvc 0" is normal (based on 
http://www.cisco.com/en/US/tech/tk39/tk51/technologies_q_and_a_item09186a0080111154.shtml)

...
 vbr-nrt 2048 2048 256
  tx-ring-limit 16
  oam-pvc 0
  encapsulation aal5snap

vs
...
  vbr-nrt 2048 2048 256
  tx-ring-limit 16
  oam-pvc manage
  encapsulation aal5snap

Cheers!

John,
Just "no oam-pvc manage" then to disable all OAM management.

Have a look at this for other possible options:
http://www.cisco.com/en/US/tech/tk39/tk48/technologies_configuration_example09186a0080094570.shtml#summary
It would appear that by using "oam-pvc <0-600> configured without the manage 
keyword" you can stop it from taking any action on OAM received or not.

regards,Tony.

Hi John,
Try "no oam-pvc manage cc" under the PVC to stop sending of
 CC.

regards,Tony.

Hi Guys - We have a number of atm pvcs to carrier (For client tails) and we 
have a small number that experience outages(weekly) - The carrier has been 
investigating for months, and they have requested we disable ATM F5 OAM 
Loopback / Continuity cells on the PVC's on our core(Apparently in some 
instances, there end is not responding to these OAM/CC and they think this may 
be the cause)

I've looked this up, and have come across the following doc: 
http://www.cisco.com/en/US/docs/ios/12_0s/feature/guide/24soamcc.html  but it 
doesnt really state how to stop(disable) our atm pvc from sending the OAM/CC ? 

Platform is 7200 

Cheers
