The Cisco Catalyst 3850 is hardware capable for 802.1ae on all ports on the switch. Software support will be available later. What management ports are available on the Cisco Catalyst 3850? The Cisco Catalyst 3850 comes with a 10/100 Ethernet dedicated management port on the backside of the switch right above the console port. 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. For the most part we can plug in the following commands when the stack is already in install mode and the stack comes up without an issue upon reload. Software install file flash:/cat3kcaa-universalk9.SPA.03.06.06.E.152-2.E6.bin new force reload yes.
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.
 LINE Reason for reload
 cancel Cancel pending reload
 slot Slot number card
 
Switch#reloadat ?

 <1-31> Day of the month
 MONTH Month of the year

LINE 
Switch#reloadat 21:05 PDT Jun
LINE 
Switch#reloadat 21:05 ?
 LINE Reason for reload
 
Switch#reloadat 21:05 ?
 LINE Reason for reload
 
Switch#reloadat 21:05 Upgrade ?

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:
Switch#reload at 21:05 6/09/15 Upgrade

As you can see, this shows I am using code version 03.03.02. This is my non-production stack.

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)

Update - 6/10/2015
Reload/Upgrade successful!

Here is what the switch does when you are logged in to it.

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.Cisco switches can be used as plug-and-play devices out of the box but they also offer an enormous amount of features. Although the main purpose of the switch is to provide inter-connectivity in Layer 2 for the connected devices of the network, there are myriad features and functionalities that can be configured on Cisco Switches.
In the following Cisco Switch Commands Cheat Sheet, I have tried to include the most important and frequently-used CLI commands that Cisco professionals encounter in real world networks. I know that the list is not exhaustive but I believe that the most useful commands are included. Make sure to download the whole commands cheat sheet in PDF format below so you can print it or save it on your computer for future reference.
