No fast path on bridge?

acidsas · February 20, 2015, 5:25pm

Hello!

I have a RB922UAGS as a plain wireless bridge. No firewall, nothing running on it. Just a plain WDS bridge. And I don’t get why fast path isn’t available on the bridge?

Obviously fast path not work on software bridge if you activate firewall or other settings than disable fast-path.

Full config?

Are you sure? Here is a quote from wiki:

Bridge handler

Bridge fast path is automatically used if following conditions are met:

no bridge firewall rules (/interface bridge filter, /interface bridge nat) are configured,
/interface bridge settings use-ip-firwall=no,
destination interface queue is set to only-hw-queue,
no mesh, metarouter interface configuration,
sniffer, torch and traffic generator is not running

Do you want to see export compact? I can do it later today.

acidsas · February 20, 2015, 5:43pm

Whoops, I’ve replied to your original post

All the requirements are met for the fast path. I’ll post config a little later.

rextended · February 20, 2015, 5:48pm

Sorry, I’m not english and sometime I misunderstand the question at first time ))

And I never see one point that show if fast path are active or not on bridge, only on other interfaces…
Probably fast path are active, but you can not see by reading one terminal or winbox value…

Make sure that you have wireless-fp (fastpath) package enabled.

acidsas · February 24, 2015, 10:10am

It’s an AC device, so only wireless-fp is available.
P.S. Didn’t pay attention before… Could the vlan on the bridge be the cause of disabled fast path?
@normis, anyone?

macgaiver · February 24, 2015, 10:16am

VLANs doesn’t have Fast path support atm you are right.

acidsas · February 25, 2015, 8:09pm

VLAN is the cause. Here is what support told me:

Hello,

Currently VLANs doesn’t have fast-path support.
It is in our to do list, but currently the interest about this feature is low, so we
are busy implementing other more demanded features.

Your request is noted.
