I have realized that although I have the following local users configured I cannot access with them, in fact I have added a test one and I cannot.
local user CONFIG
My nexus has aaa configured with an ISE server for authentication, with remote users it works perfect.
aaa CONFIG
My question is because I cannot do it with a local user, another thing that I have noticed is that it does not appear to me to put the "local" option at the end of the aaa command.
This is normal, thanks for your valuable help
