Jose We have HiPer DSPs and use the OID 1.3.6.1.4.1.429.4.10.36.0 on the ARC card that will return a single value for the number of active ports in a chassis. There are other OIDs around this value that will give you a per DSP card count, if you have the correct version of ARC code (4.1.50) Hope this helps Campbell - To unsubscribe to usr-tc, send an email to "majordomo@xmission.com" with "unsubscribe usr-tc" in the body of the message.
