HAP AX2 / AX3 Vlan settings

RouterOS Beginner Basics
1

I am planning to upgrade my router (RB951G-2HnD) and almost decide to by AX2 (or maybe even AX3), but I want to ask about VLAN settings for those devices.
On Bridge Hardware Offloading page I see that for [IPQ-PPE] for these models “Bridge VLAN Filtering” will disable HW. In comments for Bridge VLAN Filtering feature said that:

“Currently, CRS3xx, CRS5xx series switches, CCR2116, CCR2216 routers and RTL8367, 88E6393X, 88E6191X, 88E6190, MT7621 and MT7531 switch chips (since RouterOS v7) are capable of using bridge VLAN filtering and hardware offloading at the same time, other devices will not be able to use the benefits of a built-in switch chip when bridge VLAN filtering is enabled. Other devices should be configured according to the method described in the Basic VLAN switching guide. If an improper configuration method is used, your device can cause throughput issues in your network.”

So can HAP AX2 / AX3 be configured with Bridge VLAN Filtering (even without HW) - will they work with such configuration ?
Will HAP AX2 be enough CPU power for that or better to buy AX3 for VLANs without HW?

Or maybe i need some other configuration for VLANs - i do not understand which configuration is correct for AX2 / AX3 from Basic VLAN switching guide (https://help.mikrotik.com/docs/display/ROS/Basic+VLAN+switching) - “Other devices with a built-in switch chip” or “Other devices without a built-in switch chip” ?

Thank You.

Yes and yes.

And no, there is no other way of configuring VLANs on hAP ax2.

My experience with older hAP ac2 (which also lacks HW offload of bridge … but suports legacy VLAN config on switch chip) is that CPU can bridge at wirespeed. However, hAP ac2 spends most of available CPU cycles when bridging all wired ports which in turn means lack of CPU resources for other tasks (routing, wireless). Official test results show similar performance of both devices, so I’d expect to see similar CPU load due to bridging in software.

Both AX2 and AX3 can run VLAN Filtering, but that will not be hardware accelerated.

Yes. They should handle wire speed quite well.


You’ll have to follow the “other devices without a built-in switch chip” manual at the bottom.

Thanks a lot!
