Ooh, that's a good one!  From your original post we were all assuming that
the Cisco and Motorola gear were directly connected, as the case would have
to be for our "fixes" to work.

In your case, things are different:  the encapsulation is not end-to-end,
but only from the Cisco to the cloud, and from the Motorola to the cloud. 
CDP runs at the datalink layer in SNAP frames, IIRC, which the Motorola gear
doesn't like.  To top it off, not only is CDP in SNAP frames, but it's
cisco-specific.  No wonder the Motorola stuff didn't like it!

Thanks for yet another good troubleshooting quiz!
