If you've changed from SNMP version 1 to version 3 on the device, you need to make sure you've done it on the DCE side too. Without knowing exactly what you've done, I suggest looking at k-base FA158442 which should help to guide you in this change. If you need to troubleshoot SNMP itself, perhaps looking at k-base FA226273 will help in troubleshooting SNMP. What version DCE and NMC firmware are you using? There could be issues there as well but without knowing any detail, it's tough to give further guidance.

Thanks for help me, I used the APC SNMP device configuration from DCE client for switch from SNMP v1 to SNMP v3, but after delete the device and discover again the communication from DCE to Device was restore.
