BUG on RouterOS 4.11

RouterOS General
1

tested on rb450g:

  • create a bridge1

  • add ether1, ether2 on bridge1

  • delete (no disable) bridge1 without remove first ether1,2 from bridge ports

  • go to interface/ethernet ether2

  • try to set master port … router os says that port is already in bridge

bye

Little help in config RB450G

Well, just deleting the bridge would still have the ethernet ports assigned to a bridge port with “unknown” bridge value.
Delete the bridge ports and assigning the ethernet ports to switch will work again.
