Bridge VLAN's in v7 Firmware

RouterOS General
1

I just started working with v7 routers. I have been avoiding it because I like to stay with Long Term firmware versions, but with new routers, it isn’t really a choice.

In a recent bridge setup I noticed that VLAN interfaces assigned to the bridge and added as ports in the bridge show up as ‘disabled port’. This doesn’t seem to affect functionality but it does not match what I am used to seeing in 6.48 and 6.49. If they are sub-interfaces on the bridge, why do they sow up as disabled?

If you used something like this:

/interface/vlan
add name=vl333 interface=bridge vlan-id=333

/interface/bridge/port
add bridge=bridge port=vl333

… then this is wrong and has been ever since Big Bang. Vlan interfaces should never connect both ends to same bridge, it’s creating a loop. Newest ROS versions just highlite this error for you.
