Hi Butturwa,

 

Nice writting !!

 

Question, if i want to upgrade ROMMON and IOS in C4500X VSS, what is the proper step?

 

Start from upgrading passive unit ROMMON, then manually promote this unit become active after restart.

Same action apply to the next unit.

 

Can i upload both ROMMON and IOS into box, set the path and reboot? (shortcut one step)

 

Thanks
