Nexus Switch Upgrade

[fatalXerror]

Hi Guys, I am not that familiar about Nexus devices but may I know if I do an upgrade in a two node nexus 9k cluster if both switches will reload at the same time regardless if my method is ISSU or not? Thank you

If they are part of vPC - then reload one at a time ( so if the end side have dual connection) - not service effected

if the device is single home that connected to SW1 or SW2 will have service interuption after upgrade and reload time.

make sure you check the release notes and step upgrade may required the verison you looking to upgrade.

exmaple nexus 5K upgrade part of vPC :
