Solved: Hi Experts, I would like to know if, lets say, we have 5 or 6 switches in a stack, but I want to reload all the devices at once, which command should I use? I have seen the reload slot i d command, but the slot is referencing the switch. Command Reference, Cisco IOS XE Everest 16.6.x (Catalyst 3850 Switches). Removed—A switch that was present in the stack was removed using the reload slot command.

These steps are from a high level view and cover the overall process. Some steps are omitted.

Download the IOS and place it on a thumb drive, or tftp etc.

When complete:

After reboot/reload etc. Living sky casino brunch buffet.

After the switch is back up, if you have a stack type:

If there is a mismatch you can enable auto-upgrade. So all switches added get the later version and “match” the stack.

Cisco 3850 Reload Slot Commands

You must reload the newly added switch only; a full stack reload is not necessary. In this case, the newly added switch is switch 3, so the reload slot 3 command is entered.
Tip: The slot mentioned in these commands designates the switch in the stack (slot 1 = switch 1).

We are currently suffering from a couple bugs (one internal which causes the switch to reboot and one cosmetic bug that just fills up our syslog server). Consequently, we are upgrading a total of 92 Cisco 3850 switches over the course of 2 nights.

I decided to set up constant pings to our devices and use the 'reload at' command to reload all of the switch stacks on all 6 floors of one building at the same time.

We are currently on code version 03.03.05 and are upgrading to 03.07.00 at the advice of Cisco TAC.

I couldn't find much good documentation on the 'reload at' command so I used my test switch stack to figure it out (using the question mark on the CLI is kind of ambiguous).

Below shows what I typed into the CLI:

/noverify Don't verify file signature before reload.

That is what I mean by ambiguous.. It keeps giving me that 'LINE' command.

After some trial and error, I figured out the following command works:

or a specific time:
Switch#reload in 120 (reloads the switch in 2 hours)

Update - 6/10/2015

We are no longer on IOS 03.07.00 and have actually downgraded to 03.06.04 which is the recommended release. We were having some 'bug'gy behavior.
