I bought IE-2000U-8TC-G last year. They came with ios 15.2(4) EA8 and support PTP.
This year I got a smaller application. So I bought IE-2000U-4TS-G which came with only 4 ports and same ios 15.2(4) EA8.
However, I found that the 4TS-G doesn't support PTP. Its CLI help doen't even show any PTP commands or options.
Do I need to change to the bigger model to get PTP? Is there any ios upgrade to get PTP works in 4TS-G?
