Hi Dominic,

As you said that switches are in stack, they themselves elect a stack master and which is used for further topology election.

When u change any switch in stack or a switch boots the election process starts to elect the stack master. which causes the toplogy change.

please rate if it helped you.

regards

No new switch were added to the stack and every access port is in portfast/bpduguard.
