ReloadWe 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.

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. Edit 1: To set your stack member priorities, you can use the command switch priority. Not everyone knows that the reload command permits to schedule a reboot system; for instance, to plan a night router restart or during a critical configuration (AAA, vty, and so on). There are two ways to schedule a reload system: at: at a specific time/date in: after a time interval The ‘at’ keyword permits to.


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
<cr>
Switch#reloadat ?

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

LINE <cr>
Switch#reloadat 21:05 PDT Jun
LINE <cr>
Switch#reloadat 21:05 ?
LINE Reason for reload
<cr>
Switch#reloadat 21:05 ?

Software Install Command Cisco 3850

LINE Reason for reload
<cr>
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.

NOTE: Mr. Bray recommends disabling the ability to recover the password/config with one of these commands (varies):
no service password-recovery or
system disable password recovery switch all

Apply power to the switch. Immediately press the Mode button while the System LED is flashing. Hold the Mode button until all the system LEDs turn on and remain solid; then release it.
