In today's Tech Talk we are taking you through how to upgrade your Cisco Switch. Instead of the traditional bundle mode, we are showing you the second version, Install Mode. Check it out!
Thanks for this video. I need to add a 3rd 3850 to a stack of two which are running a deprecated IOS version. They are running "install mode". Is there a way to copy the IOS package to tftp and then install it on the 3rd switch?
Hi, Thank you for the video, ok, I'm looking at adding a new switch to several stacks. The older switches were on version 16. are in install mode, the new switches are on version 17.x. We are not ready to commit to the newer IOS yet, so I need to add these switches but keep the existing IOS running, how do I add these new switches effectively downgrading the new ones? Cheers Martin
What if I have physical maintenance scheduled, and I just want to reboot the switch one time (when we are)? If I said NO on the, do you want to reboot the switch now? How may the switch perform the upgrade after a physical reboot, sort of speak
Commands are not clear to see. It would have been good if you have maximised the font or CLI to see which commands you are using. Other than that, it is a useful info...
Hello , I would like to know about the possibility of rollback if there is an issue after upgrading the IOS, could you tell me if it is possible to rollback after the commit? and also, what are the commands to operate the rollback. Thank you in advance
If you want the switch to boot into bundle mode just copy the .bin file to every switch in the stack, then just update the bootvar with the new image name. Example: config t no boot system boot system switch all flash:My.New.IOS.Here.bin end wr Then perform the reload during your next maintenance window. Please make sure the verify the image prior to updating the bootvar.
