CMM4 is available with or without a switch.
I believe the CMMmicro (CMM3) was the only CMM that contained
hub/switches. Everything else was passthrough.

If I am not mistaken, the original CMM had a hub.

My issue with the CMM-type products is they're all switched,
correct? I want no layer two devices between my radio and my router.

.....also the PMP100 SyncInjector from Packetflux ought to work
with ePMP. You might want the gigE version, but in the real world
with a mix of subscribers at different MCS levels I'm not sure how
likely you are to exceed 100x100.
The CMM4 is a much more rugged beast. It is expensive, but you
are not likely to go back and wish you'd bought the cheap one.
My plan is to hook up the internal GPS and have it available, but
also to provide sync over power. Once you are using GPS sync to
re-use channels it becomes critical that it's always working, so
better to have two timing sources available IMO.
They have built in GPS if youre on a budget, not sure why alot
of people are so die hard against using it

I’m looking at ePMP w/channel reuse from a cost-comparison
standpoint. Trying to figure out how much I need to spend
on GPS synch for a 4 AP/ 2 channel cluster. Does it need
to be a CMM4? I will want to be synching multiple POPs…
