I am using an RB5009 with ROS 7.17rc2 and would like to add multiple wAP ax in future. Do I see it correctly, what I don’t need to add any wireless package, as CAPSmAN is now integrated? I do have
/interface/wifi
which seems to provide the CAPsMAN functionality? My setup is very simple. I have a single bridge without any VLANs.
I currently did prepared this configuration. Is this enough for CAPsMAN on RB5009 side? I want so have 2.4 GHz and 5 GHz on the same SSID. Can I start without certificates? I so plan to use my own CA anyway. The current used certificates are generated by ROS.
You don’t need anything else on RB5009 except for base ROS package, capsman is available and can be used.
High level it looks ok with some remarks:
You allow channels on 5Ghz which may result in overlaps/interference if you use 160MHz on your APs (e.g. 5180 and 5260, 5500 and 5580).
You also let the AP choose which frequency to use (from a limited list). I prefer to choose myself which AP has to use which frequency (through provisioning rules based on radio MAC). But that’s my view.
Since you use datapath, I am going to assume you plan on using VLAN later on ? Be careful with bridge settings on controller and AP then.
Indeed, thanks for the catch. Somehow I was thinking in 80 MHz steps, but yes, I would like to use 160 MHz.
You mean my settings in
/interface/wifi/provisioning/export
, but instead per AP and Radio MAC defined there? I guess, by setting which frequency you mean, so you don’t have any overlapping, which could happen, if AP chooses on its own a frequency from list?
No. I won’t use any VLANs in future. Seems, that I haven’t understood datapath at all. I though, this is always for communication needed.
Yes. If you let them choose, it might still happen some APs end up using the same frequency. And it's a matter of time or luck if/when reselect process will take care of it (at a random moment) and choose another frequency.
Better to choose yourself so you know where it has to be.
This also allows you to avoid some frequency on one side of the building which can perfectly be used on the other side. As an example.
But again, that's my approach. Not everyone does it this way and that's fine too if you accept the consequences
No problem. As it is now it doesn't do anything so you can leave it.
Thanks! My wAP ax now arrived and I did a first test with one device. Works fine with CAPsMAN
I have a small question about that. On my RB5009, “cap-wifi1” and “cap-wifi2” do show up. Is there any way to rename the name? As those interface are auto generated on RB5009 and managed by CAPsMAN, I don’t see any way to rename it?
Also, is this normal, that its shown like:
operated by CAP AA:BB:CC:DD:EE:FF%bridge, traffic processing on CAP.
I mean here
%bridge
. That’s a strange way of display the interface by
%
?
Also suprised, when running a simple speedtest on client, CPU usage on wAP ax goes up to~50%. Is this normal? I suspect, this could be something related to traffic processing on CAP?
Base string to use when constructing names of provisioned interfaces. Each new interface will be created by taking the base string and appending a number to the end of it, a number will only be appended if the string is not unique.
If included in the string, the character sequence %I will be replaced by the system identity of the cAP, %C will be replaced with the cAP's TLS certificate's Common Name, %R, or %r for lowercase, will be replaced with the CAP's radio MAC
Default: "cap-wifi"
Lots of information can be found in the documentation:
Are you using btest, or are you testing with a test tool like iperf (or speedtest)?
Great. Thats helps! Should answer most of my stuff
Neither nor. I meant with client my iPhone and ThinkPad. When both just produce traffic, like speedtest.net, the cpu usage seems pretty high? I have no firewall rules. The wAP ax is only used as a "dumb" AP.
