I know this video is a few years old now, but still informative. When you upgrade does the process upgrade both the Active and Standby supervisor ? or just the Active first then you manually failover to the standby and repeat the process ?

Thanks for the video, is this process to same for a single supervisor card and a dual supervisor card?

[RePeR]

with dual sup, will the whole switch reboot and be offline or just one sup at a time with transparent failover?

[shubhanshujaiswal]

Why dont we do the ISSU upgrade and be online all the time in case of dual sup as well?
