Hi,
Thank you very much for your answer.
- What do you see in the logs of the standby controller? Do you see any errors?
Concerning the logs, when we checked with the TAC, there was nothing, as if the AP207 weren't even trying to be attached to the standby... No mistakes... On the other hand, it is clear that during failover, the standby becomes the master and that the AP365s are correctly connected.
- Do you see any connection attempts from the AP in the #show datapath session | include [AP IP ADDRESS]
I'm not at my client's house right now, normally tomorrow I could provide that information.
- Do you see any Flags in the #show ap database?
The only flag found on the terminals is "f" : No Spectrum FFT support
- Is there sufficient licenses/centralized licensing enable?
Yes we have 50 additional licenses, and centralization is enabled. At the beginning of my investigations, I thought that was the problem. So I logged on to the standby during the failover, and I could see that all the licenses were switching correctly.
- Do you have the corresponding DHCP on the Standby?
For the moment, the DHCP server is only on the master, because the range that has been reserved for me for addressing the terminals is /24 and I have 192 APs installed. I was told that I could not set the same IP address range on both controllers.
Thank you so much for your help.
