Simple and straightforward video that cuts right to the meat of it! Just what I was looking for! Thanks! Should also mention that the "auto-upgrade" only works when the switch is in "Install Mode"
hai ali, i see on show switch there are 5 switch but with priority 10 not become master but standby, could you explain it why?which i know stack always find lowest mac address but if we set priority highest, it's become master
That's right, if you set higher priority it should become the master, in this case I had to reboot the stack and then it came up as expected (the higher priority switch is Master/Active)
The standby switch with second highest priority will assume the role of the Active switch. Setting priority value is important (example: switch 1 priority 15) to make sure a switch is elected as Active.
Hello Ali, to remove the old switch, do you have to issue the command no switch stack-member-number provision on master, or the master will automatically remove the old switch provision?
Yes, to remove it, you have to use the 'no switch stack-member-number provision' on master or the information of that switch will stay as 'provisioned' in the running configs
The priority is 1 by default. You can double check it is 1 if you don't have any previous configurations, so that it doesn't affect other switches when it boots up.
Yes, it has to be the same model, IOS version and license level. The only module you can add to this switch is the Network Module if you need fiber/copper ports for uplinks.
Hello Ali, What about the configuration of the new (replacement) switch? Should we copy all config the same from old failed stack member to new switch? Thank you!
No, you don't have to copy the configurations. The new switch has to be on the correct version and license level, lower priority than the master, and it will get the configs from the master automatically.

Thanks buddy
What if the switch that needs to be replaced is the active switch with highest priority?
The standby switch with second highest priority will assume the role of the Active switch.
Setting priority value is important (example: switch 1 priority 15) to make sure a switch is elected as Active.

Do we need to set the priority on new member switch
The priority is 1 by default. You can double check it is 1 if you don't have any previous configurations, so that it doesn't affect other switches when it boots up.
Hi. If a 3850 in stack mode fails. i will have to replace it for a new 3850? this switch isn't modular right?
Yes, it has to be the same model, IOS version and license level.
The only module you can add to this switch is the Network Module if you need fiber/copper ports for uplinks.
Hello Ali,

No, you don't have to copy the configurations. The new switch has to be on the correct version and license level, lower priority than the master, and it will get the configs from the master automatically.
On which switch you configured that command ?
Software autoupgrade enabled ?
On the master switch of the stack, so that it upgrades the newly joined one to the same IOS version
