CRS125-24g-1s-2hnd Hardware offload?

RouterOS Beginner Basics
1

I have a CRS125-24g-1s-2hnd at work with ROS 6.48.4 and QCA-8513L switch chip. We are simply using it as a switch and WiFi access point. Just have one bridge, no VLAN’s, no firewall, no DHCP server, etc. We’re not having any problems but I noticed that the “H” flag for hardware offloading is not showing in the bridge->ports screen of Winbox. Just curious why this is?

According to this https://wiki.mikrotik.com/wiki/Manual:Interface/Bridge#Bridge_Hardware_Offloading the CRS1xx/CRS2xx series support it so long as you’re just dong the basics like RSTP.

How is anybody supposed to guess unless you provide a configuration export?

Almost all ports in /interface bridge port have “hw=no” … change that to yes (export will not show that property any more as it only shows items set to non-default values).

And ether24 and sfp1 seem to be slugged for some reason.
I would tidy up all these back to the default values (and set the 100 Mbps stuff to 1 Gbps on the ether ports, even though auto is set and overrides them) unless there is a good reason not to.

Strange… In Winbox I didn’t see a way to turn on Hardware offloading. I thought it was automatic so long as you didn’t have something like Vlan filtering enabled. I did it from the command line and it worked. Now I see the option in Winbox show up too. Thanks for the tip. As far as the Ethernet speed goes, most of the equipment at this location has older NIC’s only capable of 100Mbps. Since this is a production environment I’m not going to mess with that right now.

I see what you mean about ether24. I missed the 10Mbps there. Definitely something that needs to be addressed when it be down.

As @sid5632 already noted, that setting doesn’t matter as long as ports are set to autonegotiate. Up to around 6.40 (could be 6.42) default speed setting was 100Mbps and upgrades don’t touch settings … since export shows any settings different from default this setting started to show after default changed. There’s a whole array of speed settings (announced or not) which affect port speed when autonegotiation is enabled.

Got it. Thanks to you both!
