MX84 HA vlan mess

@PhilipDAth

After updating my HA topology to what you can see at the end of this thread (see topology with additional red links):

https://community.meraki.com/t5/Security-SD-WAN/MX84-HA-setup-tagged-WAN-ports/td-p/24988

I am now seeing some really weird messages on my log.  

I assume those messages are not harmful, right? 

What I think is happening is that the Internet traffic is landing VLAN1 and it is getting mixed up with my management traffic

[PhilipDAth]

What it means is traffic is being received by that MX on a VLAN with IP addressing belonging to another VLAN.

For example, lets say you have configure this on your MX:

VLAN1: 192.168.1.1/24

VLAN2: 10.0.0.1/24

The MX should not receive traffic from 10.0.0.0/24 on VLAN1 - that traffic should be on VLAN2.

@PhilipDAth I was trying to put my internet traffic in two separate vlans. The issue I am facing now is that switch usw-b is using port#1 as designated port. Port#1 is my connecting to my ISP and it is untagged. Ideally (and w/o modifying my topology) I would like to have port#4 as the designated port. It seems due to spanning tree tie breakers port#1 is designated because it is the lowest port number. Any idea other than either adjusting the path or switching the link between switches from port#4 to port#1?

[PhilipDAth]

Do your switches support adjusting the spanning tree port priority?

@PhilipDAth yes. I guess it is an option. Sor far o guess the option is supported via the CLI but it is not visible within the controller

Is that a better option?
