i have 4 cisco 3850's set up in a stack 1-master 2-secondary 3-member 4-member, however when i unplug-replug a stacking cable both member switches restart, 1 and 2 are unaffected.

stacking is set as

1-2
2-3
3-4
4-1

when a cable is unplugged the switches continue to work fine, however when the cable is plugged back in 3 and 4 restart.

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Do they show as members of the stack?
If you run: show switch

What does it show as their current state?

Make sure you have set the priority for master and backup master manually to avoid an election with one of the members to take over either of those roles unintentionally.

Hi All,

Sorry - poor form, left this to go stale. Basically ended up re configuring the who stack - problem persisted. Transpired one of the stacking cables was bad. It was seen, as 50cm in length etc.,  seemed to work fine, but intermittently just went offline. Swapped this out - all good.

Thanks for the comments/assitance above

Regards
