Cisco Reload Slot Command
Almost all Cisco devices use Cisco IOS to operate and Cisco CLI to be managed. The basic CLI commands for all of them are the same, which simplifies Cisco device management. Here is a Cisco commands cheat sheet that describes the basic commands for configuring, securing and troubleshooting Cisco network devices. You can use the reload at command to schedule a reboot of the whole stack but there is no way that I'm aware of to reload an individual stack member at a specific time, without resorting to third-party tools to issue the reload slot command at a specific time. This video describes how to use the Cisco Reload command. In addition, it provides some strategies for using this command. 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 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:
Cisco Reload Ospf
Cisco 3850 Reload Slot Command
You can also issue the following command to reload on a specific day:
Switch#reload at 20:00 07 Dec Upgrade
or a specific time:
Switch#reload in 120 (reloads the switch in 2 hours)

Reload/Upgrade successful!
Here is what the switch does when you are logged in to it.
