    Node goes down minutes after successfully adding it to NPM


      I have two Cisco switches(A&B) that are attached to other Cisco switches(C&D).  I added switches C and D to NPM, they are working fine.  Using the same commands on switches A&B, I was able to add them to NPM as I have done with every other device. The problem is, minutes after adding them successfully, NPM reports them as down nodes.  However the switches in the middle (C&D) are working fine.  Has anyone had this problem before?  I have other instances where I have multiple SNMP devices stacked on each other, and they are working fine.  This is the first time I've had this issue, and the first time I've been forced to use Cisco devices.  Could this be an issue related to Cisco, or do I need to add SNMP commands to allow pass thru of SNMP traffic?

      Any help is greatly appreciated.
