Hallo MikroTik, I would like to discuss layer3-offloading (again), I hope some of you guys is reading this. I am trying to understand the actual functionality. The only reference I can find in L3HW Feature Support is: This works only for directly connected networks. Since HW does not know how to…

Try upgrading to v7.6 - maybe you encountered some of the issues above. Running on 7.6 already during the issues, on CRS309. I just tried again with non-tagged ports instead of tagged. And gave it some stress with 8 clients. Same issue: all worked perfectly for an hour or so. And then suddenly…

@Mikrotik What’s the progress on hw offloading vxlan? Particularly on CRS317, we are looking to do a project with 100+ CRS317 switches, L3 HW, and VXLAN. So the vxlan performance would need to be near wire speed. Thanks!

Try disabling Bridge Firewall and see if that helps: /interface bridge settings set use-ip-firewall=no use-ip-firewall-for-vlan=no I now have some funny results: with /interface ethernet switch l3hw-settings set fasttrack-hw=yes icmp-reply-on-error=yes ipv6-hw=no pretty much no traffic passe…

If I however switch global l3-hw-offloading OFF interface ethernet switch set 0 !cpu-flow-control l3-hw-offloading=no mirror-source=none mirror-target=none name=switch1 all of a sudden I get near line speed NAT (I have a 1Gbs WAN and I reach that). I do not see the H flag in the firewall conne…

I will need to test this tomorrow or when I have time. You are probably quite right. When I did a quick check I indeed noticed a load on one core of upto 80%. I did not think about it more as I did not realize that the CRS317 might do 1Gbs as I only looked at the 512 bytes result for 25 rules (423…

Hello, a little bit dumb question… In a basic SOHO enviroment, is L3HW useful only when multiple subnets, firewall rules or routes are involved? As example in a CRS switch L3HW is supported but not usefu (in most of cases), correct?

For soho, if you only have one subnet and you are not using the switch as your main router, then there really is no benefit. If you have multiple subnets/vlans on your network but use a separate router, then yes there is a definite benefit. If you use your crs device as a router, it might be bette…

I’m using a MT router for handling PPPoE, couple of VLANs, Firewall, DHCP, etc… a CRS device wtih the trunk port to the router, connected devices are separated from VLAN A and VLAN B. From what I understand using L3HW is ignoring firewall roules, but those roules are “managed” by the router, in fac…

Here is a snippet - not going into the actual enabling of l3hw as that is in the manual/wiki. This should be most of it to understand how I use it. CRS317 /ip address add address=192.168.6.1/23 interface=vlan600 network=192.168.6.0 add address=192.168.5.1/24 interface=vlan500 network=192.168.5.0 …

how does L3HW actually works?
