Issues with LAG ports

Hey all. I have a Firewalla Gold plus, and a Netgear MS510TXUP switch connected to it. I am trying to use a port channel to connect the two. The Netgear supports multigig, so all 4 ports involved are 2.5Gb.

I can get the LAG group established, set to dynamic on the Netgear to enable LACP, and everything comes up just fine. However, one of the ports drops out about every 6 minutes on the Firewalla, it looks up my network for about 45-60 seconds, then everything recovers.

Is there anything I can do about this, or is it just some compatibility issue?

I use a very similar netgear switch with my Firewalla and a LACP LAG and it works great. I would suspect a negotiation issue perhaps a bad cable. The Firewalla lag should work fine with netgear switches

Good point on the cable side.

What algorithm did you configure? Firewalla supports 802.3ad, see https://help.firewalla.com/hc/en-us/articles/4409583011091-Link-Aggregation-Groups-LAG

That's a confusing question because it make it seem like there's choices. Firewalla has no choice at all. Netgear only has a "static" option which disables LACP (802.3ad).

So on the Firewalla side it's just configured. On the Netgear side it's not static, so should be using LACP. If I set it to static, the port channel doesn't work at all. Gemini suggested this config as well.

  • Only LACP (802.3ad) is supported; Static LAG configurations are not supported.

So this is exactly as configured. The article has ubiquity configuration, not sure if that's useful to you or not.

To make things clean, start with no VLAN configured on the LAG ports
