Solved: Managing a Cisco 3850 Stack

tekgod001 · ‎05-11-2016

Hello ALL,

I have got a Stack for 4 X 3850 and planning on removing the last member from the stack. I understand I need to Issue the command no switch stack-member-number provision after powering down the switch4. I am trying to find out how the sequential stack cables will be reconnected, in this case I will remove the stack cable connecting switch 3 and 4. Move the stack cable connecting switch 4 and 1 to switch 3, would this require switch 3 to be powered down as well ?

Based on the image below

Hi

No you shouldn't have to power down 3 , stack cables can be removed/connected while device is live without interruption to production traffic

Hello

It would be fine however please be aware as you are doing this the full speed fabric backplane of the stack will be depleted until the stack ring is closed off by connecting switch 3 port 1 into switch 1 port 2

(that if your existing daisy chain stack ring is 1-2, 1-2 , 1-2, 2-1 )
