ZTP Not Working After Firmware Upgrade On AIRWAVE - Switches Registered To Airwave Gets Disconnect


There is a new update for Airwave 8.2.5 and 8.2.6 and after that upgrade is performed the switches connected to airwave will get disconnected.  Previously both Airwave and Switches worked on TLS 1.1 which was enabled on the switch by default but after the new update on Airwave the TLS has been updated to 1.2 hence the switches will not be able to register on the Airwave. 


We have customers calling in for the same issue hence wanted to inform about the same as i have already tested on a live network.


Resolution :


Upgrade the switch to latest 16.06.0006




We can configure Airwave to work on TLS 1.1 which is not recommended by Airwave.


We can go ahead and enable TLS 1.2 manually only the switch by command “tls application all lowest-version tls1.2 ”
