Two Active Switches With Redundant Uplink
Hi, I am looking to connect both switches to my Firewalla each on port one. I am also looking to create a LAG between the two switches on the sfp ports. I am using the default vlan to assign ip add...
These MS510TXM are not L3 routers. Of course, you can configure two or more VLANs. Don't know anything what should be special about your firewall and it's port 1.
Typical cause for loops could be failed attempts to configure LAGs for example.
Appears somehow you managed to create a loop on your network. Impossible to tell based on what you posted.
- No, the switches are not L3, but port 2 on the FW is connected to one switch and port 3 to the other switch. The switches are connected via SFP. The traffic from the FW is Trunk VLAN 2 & 3. The SFP link is also Trunk 2 & 3. I would think that MSTP could prevent loops?
To answer my own question:
I did not need to enable MSTP since each switch is 1 hop from the router. What I needed to do is under, Switching => STP, enable the option for "Forward BPDU while STP Disabled" and disable "Spanning Tree State". This allows the router to receive the packets that it is sending out and properly map out the network.

Wild guess: These two router ports which are supposed to seamless connect both switches, providing a single STP environment, or for the allows to run two MSTP entities are mainly L3 router ports, without much L2 support - or the L2 STP/MSTP config on your router requires a review.

With al due respect, this reads like a hack, not a solution.
