Etherchannel with Redundant Radio Links

RouterOS Wireless Networking
1

Hi everyone
Here is our current setup:

3850------MikrotikRadio(Bridge)------3850

we are going to increase fault tolerance because cheap radio links are not safe ( We had some failure experiences and down time! )

So we’ll have :

3850 portA-------Mikrotik(bridge)--------Port A 3850
3850 PortB-------Mikrotik(bridge)--------Port B 3850
and port A,B will be in Layer 2 etherchannel

Here is some questions:

  1. Does it work ? ( Mikrotik radios should pass everything fine like a copper link - without any limitation about different protocols )
  2. What happen if RadioA in site A goes down? I mean does etherchannel recognize it ? In theory , when LACP packets are not received in other site , the port won’t be up in etherchannel.
  3. Is there a way to automatically disable ethernet port when wireless connection goes down ? ( it will notify the switch to change state of it’s port to down and everything will be fine )
