Re: Does NOS 5.0.2c and NOS6.0.2c support Mixed-node fabric cluster?

Hi,

 

Mixed version fabric NOS 5.0.2c and NOS 6.0.2e is not supported.

 

show fabric all as you can see with show that fabric has formed (data plane)

 

show vcs will only show fabric members running same version (control plane)

 

The data plane will function with mixed versions this is to support mixed versions during an upgrade when different members may be on different versions of code, but vcs fabric will not form with these mixed versions.

 

The output you see is expected

 

Hope this clears this up

 

Regards

Mick
