Out of curiosity: Shouldn't the ISSU (incompatible or not) be started exactly by upgrading the IRF Standby member first? ...Chassis 1 in the above scenario.

Hi Yvan,

As soon as we lauched the chassis 1 reboot, point 4 in your message, chassis 2 shut down all its ports, excepted the ones excluded of course, and we had to run the command mad restore to re-establish connectivity int the datacenter.

Hi Parnassus,

So can I assume that the best way to do this kind of upgrade, is to have chassis 1 as master before the operation, to make the operation easier?
