I hope you can support me with the following problem that I presented myself yesterday.
I have an X440-24t (XOS 184.108.40.206-patch1-19) connected to a BD-8810 (XOS 220.127.116.11) via a Link Aggregation.
In this switch I have the primary and secondary DNS servers connected.
As part of the maintenance, XOS is updated to the XOS version 18.104.22.168-patch1-9, which is recommended by Extreme.
After restarting the switch, the DNS servers stopped responding, even the fans showed fail. The equipment could be administered with its administration IP.
When returning to the memory module with the previous version (XOS 22.214.171.124-patch1-19), DNS servers respond normally.
Then load other XOS lower-than-recommended vehicles:
XOS 126.96.36.199 patch1-8
When running these versions the primary server does not respond but the secondary if and the fans do not show errors.
-The wiring is checked and correct.
-Compare the LAG configuration on the BD8810 and X440 and it is the same.
-Install another X440-24t with version 188.8.131.52-patch1-9 and the DNS server stops responding.
I had to leave the equipment with the version that I had to not interrupt services.
DNS servers are virtualized.
I hope you can support me.
