I have 2 C9500-40X switches with virtual StackWise configured with version 16.8.1a and I have had some problems:
- When I try to configure a vlan I lose connection of the session.
- When I access by Telnet / SSH I sometimes get the message of "connection refused" (I don't have any ACL that denies the traffic)
- When I manage to access the console and when I try to give a show run, it appears that the equipment is in standby mode and it does not allow me to go to global configuration mode.
I have been looking and the problems do not have any antecedents, I already checked the bugs of the version and there are quite a few but none that resembles the errors that I have.
I have the knowledge that the version is not recommended by Cisco and the only solution I have so far is to update the equipment to the most stable version that is published in Cisco.
I hope someone has an idea that could happen and guide me a bit.
