マスターが落ちた時のMACアドレスのデフォルトの扱いが
機種ごとに違うのではないかと思って、ドキュメントベースで調べてみました。
デフォルトだと、3750や29060Sが、新しいマスターのMACアドレスになるのに比べて、
3850は元のマスターのMACアドレスを引き継ぐ(stack-mac persistent timer 0と同じ?)
ということでしょうか。

By default, the stack MAC address will be the MAC address of the first active switch, even if a new active switch takes over.

When a master is removed from the stack and a new master takes over, the MAC address of the new master to become the new stack MAC router address.
