New option on RouterOS 7.19 datapath.traffic-processing

Mon May 26, 2025 7:16 am

RouterOS 7.19 has a new option:
wifi -> datapath.traffic-processing=(on-cap OR on-capsman)

How to use this?
Does anyone have a positive experience?

There is still no documentation.

good catch. I'm going to sub to hear if anyone has information. This their potential fix to performance issues when using Capsman?

Is that for handling traffic on CAPsMAN as it was on CAPsMAN V1?

How do you expect it to work and how did you test?

Expected traffic processing on capsman, i.e. no need to create bridges on CAPs.
The "datapath not supported" message appeared on CAP's wifi interface after enabling this setting. So i assumed it doesn't work. Maybe some additional configuration needed...
What's really needed is the documentation.

You aways need to assure there is a communication path from caps to manager so a bridge is needed on caps.
Default config does take care of that.

The only thing this setting should change is that traffic from caps-clients is not forwarded locally from caps device itself but first send to capsman manager (encapsulated) and from there it is decapsulated and then forwarded to the final destination.
Haven't tested it myself yet but that's how it works for legacy capsman.

a bridge is needed on caps.
Not true.
WAP01 > /interface bridge print
Flags: X - disabled, R - running 
Works absolutely fine without any bridge. What is really needed is documentation route to capsman (which is indeed exist)
WAP01 > ip route print
Flags: X - disabled, A - active, D - dynamic, C - connect, S - static, r - rip, b - bgp, o - ospf, m - mme, 
B - blackhole, U - unreachable, P - prohibit 
 #      DST-ADDRESS        PREF-SRC        GATEWAY            DISTANCE
 0 ADS  0.0.0.0/0                          192.168.100.1             1
 1 ADC  192.168.100.0/24   192.168.100.251 ether1                    0
P.S. This is obviously ROSv6.

This CAP is hap ac2. I suspect option is not intended to work on wifi-qcom-ac drivers...

Before anyone comes up with more theories about support: has anyone actually tested whether "traffic-processing: on-capsman" works in a wifi-qcom setup?

I'd also like to know this answer if backwards** compatible with wifi-qcom access-points. Or requires the qcom-ac driver....

Tested this on Cap AX. Pushed a new config with a new Datapath linked to the CapsMAN unit.
Did not work. Got the same issue on CapsMAN unit. "datapath not supported". On the CAP I saw nothing at all.
Both CapsMAN CAP are on 7.19.1 so I suspect this is something new that I hope gets introduced sooner or later but we just see nuggets of this right now.
Or MT is just messing with us :)

I've tested that on 2x wAP ax with ROS 7.19.1 with the following setup:
  • each AP has one big trunking bridge
  • each AP has VLAN Tagging for multiple WiFis
where I expected, that traffic-processing=cap means, that the traffic is leaving the AP to the network directly instead of forwarded to capsman and then send to the network.
Result: not working.
