The fallback ip was only received after the DHCP request failed - but since each radio had the "default ip" they were all on the same ip

The result was a whole bunch of radios going to the default fallback address which was - you guessed it - the same IP. Fortunately this was about 15 radios. I actually wound up plugging directly into the network segment (switch) and changing each radios default management IP manually. This was actually a network conversion moving from pppoe to DHCP (from their billing server to ours). The fallback IP is only an IP - no subnet, no gateway, so I basically picked a number in their existing legacy subnet that I did not think was being used (something like .70) and put the first radio on .71...second on .72...and so on. When it came time to switch them all to DHCP after the conversion it was pretty easy - but this took a while to do (obviously) I'd change one radio, then keep hitting fresh until the next radio came up. Sometimes I'd get a different radio with each refresh. But - eventually - they were all changed and no radios were on the "initial" fallback ip anymore and - problem solved.

Are the duplicates in the same segment? What type of router is on the headend?

I had to guess which device one of them might be, change the ip and then voila, discovery with dude found a new device which was another nsm2 with same ip.
