Anyone with experience using ISSU over non-ISSU for upgrading N7K Sup-2? Any pros/cons you can share. I recently bricked a Sup module due to attempting a ISSU (TCN/STP Halted the upgrade and caused the standby sup to loop).
I have a case open, however I would appreciate anyone with a best practice on upgrading these chassis and
why you would use "out-of-service" command and any drawbacks (software guide states you will need to physically remove the module after this command.. WHY?).
Thanks
