A commit makes an upgrade, ie. A committed package set will run after a node is reloaded. This example uses the 'software install file' command with the 'auto-rollback' command option to install the bundle onto both switches in a stack via tftp. After the switches reload with the new software, the 'software commit' command is used to stop the rollback timer and commit the candidate package set. Use this command to remove any and all packages and provisioning files that are no longer in use.

URL of the bundle to be expanded. If a network URL is specified, the to keyword must also be used to specify the destination location.

The running command option is not allowed when running in installed mode. The contents are extracted into the same directory as the source bundle by default. If the to option is not entered, the contents will be extracted into the default installation location for the platform.

This example uses the following steps to prepare a switch for booting in installed mode, i. Use the 'software clean file flash:' command to remove any unused package, bundle and provisioning files from flash:. If not used, the software is automatically committed after installation.

A value to zero means the rollback timer is never started and the software is not automatically committed need to use 'software commit '.

Does it look like Configuration register is 0x will be 0x at next reload. These bugs haven been fixed yet, but, there is a permanent work around in place. The configuration-register value needs to be 0x I have seen this in multiple customer cases and this has caused the issue almost every time. Have you checked the configuration register value?

I do not believe switches use configuration register like routers do, at least not the switches. There is a boot variable that you can change for that so instead of using NVRAM it uses another memory to read saved configurations but I checked that and the variable is at its default setting, which reads configuration files from the NVRAM.

I have tested this by issuing "copy running-config startupconfig" and then "show startup" to make sure configuration was saved. After a reload all is gone Gaberivas, I did what you told but i didn't get result, still my switch after reloading loosing all of it's configuration. I just recently had this problem too of config erasing after reload even though i had saved my config both through write mem and copy run start.

Turns out that the config-register parameter from the bootvariables was set to 0x After looking at the switch logs, I was able to see the switch has had "Express Setup" activated. Even though the suggestion by Luke makes sense, there was no cable with the cover thing pressing the mode button so I believe someone might have pressed it.

I'm not sure of how it exactly works Do I need to modify them? If the last switch I shut down is the master he won't take again the master role right?

Isn't it better to start by reloading the Master? Then the standby so the first switch re-take the master role? Buy or Renew. Find A Community. We're here for you! Turn on suggestions. Auto-suggest helps you quickly narrow down your search results by suggesting possible matches as you type.

I suggest that you go ahead and reload. If the config register is then set to 0x then the startup config should work as expected. The config-register command by itself does not fix it.

After executing the command you must reload for the problem to be fixed. Glad to know that you got it solved. Thank you for posting back to the forum to let us know how you fixed it.

Bugs Yexley. If you want to shutdown all the interfaces and turn on later you can use these commands:. So shutdown command is not required, just save your configuration and pull the power cable. I was hoping for a solution like "push the reset button upper left 8 times 1 second apart, and it will gracefully turn off" but NO.

You need a pay raise, my phone call to Cisco went nowhere, wasted 20 min. Very polite and PC. Further clarification. We have various intermittent power outages and it seems after many outages, the configuration corrupted to the point the 3 x 48 matrix stack would not restart and was stuck in some boot up loop.

SO, it would seem prudent to do a "safe" shutdown, just like a cheap PC to avoid many IT hours of being put under the gun and pressure. This is the gist of my first question. In the meantime, I guess we will have to rip the power plugs sorry for the 1st misspell! My opinion. Buy or Renew. Find A Community. We're here for you! Turn on suggestions.
