A quick sanity check if I may. Not looking for solutions\instructions, just a simple yes or no will suffice.
i’m wanting to use l3 routing for some of my subnets but other (the internet of tat) I’d like to still route via my opnsense box which will also be the default route for the subnets that are routed l3 at the switch.
At some point (assuming I get comfortable with extended acl’s) all routing may happen at the l3 switch level but the “mixed” model allows me to get the internal 10gb traffic routed at line speed at not capped at 1gb by the opnsense box, sooner.
is this possible (not how, I can read manuals and earlier posts…) ?

In the layer 3 example above, is it possible to have the switch route traffic but forward things like mdns broadcasts to the opnsense router where they can be reflected to select other vlans?

The easiest way that I can think of is to use a linux box running Avahi with an interface on every VLAN where you want to listen and repeat the mDNS queries to. Be careful with the firewall rules on this machine, or it can be used to "jump" between networks.

Having to do stuff like hoping the mdns-proxy/avahi-reflector would work stably and not cause grief for my wife is why I flattened my network back out after having full layer 3 VLAN routing done on the switch.

What is recommended for firmware L2(sps) or L3(spr)? I will be running some vlans which pfsense is handling the routing on at the moment so should I just stick to L2?

Just install SPR. That way if you ever want to experiment, it doesn't require a firmware update and reload.

Looking for a little help creating a console cable for the brocade switches. I've searched through the thread and saw other examples but for whatever reason my cable does not appear to work.

I hacked up a micro usb cable and attached its wiring to a RJ45 keystone. Green to pin 6, White to pin 3. Red & Black to nothing. And connected that to a cisco RJ45 to USB console cable.

Am I doing something wrong with the wiring?

Is the sps easier to setup or perform better?
Not in any meaningful way that I'm aware of. Fohdeesha's guides assume SPR since it has you assign an IP to a VE. I haven't had to reference it in a while, so I don't recall if he has the L2 only steps in there as well. Probably does, it's pretty thorough.

Not sure if the other switches are different but the 7250 has the following pinout for the miniusb port.mu0.png
So it looks like you are missing a ground wire?

That worked! Thank you!
I still think you are missing a ground which could cause you issues. It probably works because you have an electrical ground through your home that commons up the 2 devices but I wouldn't count on it and could even cause damage if you get too much of a differential between the devices.
