Staged upgrades - some information and a question on timing.

[cmr]

I recently upgraded a network with six switches using the stages upgrades option as below:

The actual device reboots were:

09:26 (26 minutes after schedule)

09:31 (1 minute after schedule)

10:26 (26 minutes after schedule)

10:56 (26 minutes after schedule)

The first device is a 220, the second a 120, the third a stack of a 225 and 210 and the fourth a stack of a 225 and a 210.

Probably worth bearing in mind when using this feature that the 2xx switches all reboot 26 minutes into the window but the 1xx switch only waited 1 minute!

Is this by design or is it a bug?  Anyone else done staged upgrades and experienced the same as above or different?

Hi,

There is a hold off timer of about 25 minutes before the switches reboot when you perform an upgrade to ensure all the switches in the network have finished downloading the firmware.

The reboot after 1 minute of the schedule is not an expected behavior but I would recommend calling the Meraki support to figure out why.

Thanks,
