I know the following configuration is doable, but would like to confirm the version of the NX-OS.
I have two core Nexus 9300 switches ( A & B), and two Nexus server 9300 switches ( A & B). I will be configuring dual links from each server switch ( A & B) such as server switch(A) will be connecting to each core switch(A & B in vPC), and server switch(B) will be connecting to each core switch (A&B in vPC), and vice versa.
Is there any software version limitation to configure the above?
You will see that the current long lived release is 9.3.X, and the recommended release (recommendation based on general customer experience) is 9.3.(7).
My suggestion would be to go over the release notes for the respective version and check if there are any potential software bugs (sections open issues and known issues) which can affect your network/devices, based on the features you plan to use.
