I changed the management IP on a bunch of nexus switches after which I'm not able to login with tacacs/aaa. I can login through local creds though.
I was suggested to remove the tacacs/aaa configs before the change and then add them back. But I did not understand its purpose, and I could still login after the change. But a day later, I'm not able to.
I've done an extensive research across the internet but did not find a definitive answer to this.
