Use Mikrotik hAP AC3 as combined AP/switch

Sat Jan 08, 2022 3:35 pm

Hi,

I was wondering if it's possible to configure a Mikrotik hAP AC3 as follows:
  • Use ROS 7 with newer wave2 wifi package and thus features.
  • Configure eth1 as a VLAN trunk to an upstream switch.
  • Configure eth2-5 as VLAN access ports bridged to one of the trunked upstream VLAN's.
  • Configure multiple SSID's (virtual AP's) on the 2.4 and 5 GHz radios bridged to one of the trunked upstream VLAN's.
  • Use the switch chip for intra VLAN forwarding on the eth1-5 interfaces, instead of software bridge VLAN filtering, to make use of L2 hardware offloading.
  • Configure an IP in one the trunked upstream VLAN's for device management (SSH/webfig).

So essentially I'd like to use the hAP AC3 as a small VLAN capable wave2 AC accesspoint combined with a 5 port VLAN capable switch with full L2 intra VLAN hardware offloading using the switch chip functionality instead of software bridge VLAN filtering. I already have an existing device that does all the routing (internet/inter VLAN) and firewalling.

The documentation does not really provide me with enough confidence that all this is possible without hitting a limitation somewhere such as having to fall back to software bridge VLAN filtering or the older non-wave2 wifi package.

Anyone using this device in the above fashion and willing to share existing configuration and/or experiences?

No one using the Mikrotik hAP AC3 this way or have any experience to add?

Going from the numerous complaints regarding Mikrotik and wifi on this forum and elsewhere I'm now starting to wonder if this is even something I'd like to undertake and maybe I'd be better off getting a separate VLAN capable switch and accesspoint?

Other hAP with 6.x can do this so it should be possible, just somewhat fiddly.

As RouterOS doesn't support hardware offloading for vlan-aware bridges using the Atheros 8327 switch chip you must:
1. use a non-VLAN-aware bridge (so no setting pvid= or adding anything under /interface bridge vlan)
2. configure the switch chip https://help.mikrotik.com/docs/display/ ... upExamples
3. ensure that vlan-id= and vlan-mode=use-tag are set on any wlan interfaces, remember to include these VLANs for the switch1_cpu switch port

I already have such a VLAN config running on a Mikrotik HEX PoE, using switch chip for offloading instead of VLAN filtering on the bridge, so I'm familiar with the (convoluted) config.

3. ensure that vlan-id= and vlan-mode=use-tag are set on any wlan interfaces, remember to include these VLANs for the switch1_cpu switch port

Is this also possible using ROS 7 and wave2 wifi package?

I don't have one to test, however there is no mention of configuring tagged wlan interfaces in https://help.mikrotik.com/docs/display/ROS/WifiWave2. Until this is fixed you can work around it by creating an /interface vlan attached to the existing bridge for the desired VLAN ID, then add this vlan interface plus the wlan interface to a new bridge.
There are potential issues with this setup but if you ensure that the additional bridge has spanning tree disabled to avoid https://help.mikrotik.com/docs/display/ ... linterface, and potentially use an additional bridge and VLAN interface for each wlan interface to avoid https://help.mikrotik.com/docs/display/ ... einabridge it should work.

My experience with hAP ac2 (pretty similar to hAP ac3, it's got less RAM and less storage than hAP ac3) running ROS v6 is that device is capable of bridging wire-speed without much sweat. I'd expect performance in ROS v7 to be similar to performance in v6.
In order to avoid convoluted config, go with normal vlan-filtered bridge and see if it performs fine. Could be that device will start to sweat under full wireless load (running wave2 driver) ... but the difference will only be when there will be high ether-to-ether traffic ... wireless to ether will be the same, CPU will have to do most of work anyway.

I did that to an Audience.

I also have used the WAVE2 Driver on a hap AC3 as a wap only.

But I think you need a Ruckus h510.

THis is dirt simple.
one bridge
trunk in port
trunk out ports to any other smart devices
access ports out to dumb devices
access wlans out as required.

identify vlans to bridge
assign bridge ports
assign bridge vlans

one interface=manage
trusted vlan is list member
Use manage for ip neighbours and tools winmacserver

Simple IP route to gateway of trusted vlan.
Basically done.

Hmmm, I was looking into going with Mikrotik again after a good experience using a HEX PoE as home internet router but in this case there are too many unknowns for my taste coupled with the not too stellar consumer wifi performance of Mikrotik it seems. I'm going to go with a standalone switch and accesspoint to separate both functions and be able to select both products on merit.

I use my hex as a switch works fine. :-)
Get a better router RB5009, and then something like a TPLINK eap245 if you want plain jane wifi5 or the eap660HD if you want wifi6 for example.

I have a hAP AC2 on my desk as a switch. 1-4 are local area network. Port 5 is EoIP to my office.

I'm very interested in this setup but unfortunately I couldn't get it working.
I think I cannot make the correct connection between the VLAN aware switch and WLANs through the bridge.
I'm using RouterOS 7.7 without any additional packages, including WAVE2.
Perhaps I should just give up trying to benefit from the switch chip hardware offloading?

hap ac3 uses 4019 soc, it is capable of doing this. I have rg450g4 as main router whit wave2 package, all bridge ports are hw offloaded whit switch chip vlan config method. Of course wlan interfaces will not be hw offloaded.

I need exactly this. Of course I'm not expecting WLAN HW offloading, only for Ethernet. May I ask you for some directions how to configure this? I think I'm missing the part with VLAN aware switch chip config and the connection (bridge perhaps?) between it and VLAN aware WLANs. The radio connection to WiFi clients has to be not VLAN tagged.

This is my code snippet form main router. As you can see, vlan interfaces are created on bridge, after that in switch chip menu vlans are tagged and ports configured. But be aware, this type of config can lock you out (switch chip tag must be added last, also rest of config must be correct), so have a config backup and use safe mode. This is overall concept, I suggest you to test in lab env if you can to understand how it functions.

Thank you very much for your kind cooperation!
I *think* I've managed to get the vlans working, perhaps I've missed VLAN tagging on Wireless interfaces and non-VLAN aware bridge. At least VLAN 99 on WiFi and access ethernet ports works as expected.
Now I have another problem. The device is not accessible by IP address via its management interface (VLAN 111 on the snippet below):
/interface wireless

Re: Use Mikrotik hAP AC3 as combined AP/switch

Tue Feb 21, 2023 9:19 pm

It turned out I forgot to enable VLAN filtering on CPU switch port (no.5 in this case):
/interface ethernet switch port set 5 vlan-mode=secure
In my case the device is AP and VLAN-aware switch, it doesn't route and only management IP is needet. Thus all the VLAN interfaces seem unnecessary and now I have only:
/interface vlan add interface=BR1 name=mgmt vlan-id=111
A note about Atheros 8237 says, that the default vlan-header=leave-as-is property should be used. I removed
vlan-header=always-strip
from
/interface ethernet switch port
config.
Now everything works as expected.
Thanks again! I strongly appreciate your help!

Glan it helped. Key here is to follow tag thru the path.
