@JonathanLee said in Differentiated Services (DiffServ) Identifiers:

What TOS would constitute full bandwidth use on pfSense?

pfSense doesn't use those values at all by default. You can use them in rules for shaper queues if you want to or set that for use in other devices the connection is going through.

@steveits Ahh thank you, I did Google quite a bit but didn't find that. I hope there's a solution soon.

Hmm, I'm not sure how to show that per interface. Possibly some combination of netstat -i and netstat -Q

@steveits said in Traffic not matching floating rule:

Check Status/Queues to make sure the traffic isn't actually in the queue and the state counter just isn't counting up.

Check Diagnostics/States and see if the state is matching your source. For instance in order to lower priority on a download the state may be to the webserver:443 and the return traffic matches the state but not the rule. (so, doesn't seem to count up the counter...)

Is low_priority_src a LAN IP behind NAT? If so it can't match, see https://docs.netgate.com/pfsense/en/latest/trafficshaper/advanced.html#shaper-rule-matching-tips for info on tagging it.

Brilliant, thanks so much for the hint/info on tagging!

@ibbetsion

You must have something stuck in there somewhere. I just looked on a spare pfsense box I've got, with no traffic shaping setup at all, and this is the result I see in Diagnostics->Limiter Info

Limiters: No limiters were found on this system.

If you are not using limiters, then note this from the guide;

The ALTQ framework is handled through pf and is closely tied to network card drivers. ALTQ can handle several types of schedulers and queue layouts. The traffic shaper wizard configures ALTQ and gives firewall administrators the ability to quickly configure QoS for common scenarios, and it allows custom rules for more complex tasks. ALTQ is inefficient, however, so the maximum potential throughput of a firewall is lowered significantly when it is active.

pfSense software also supports a separate shaper concept called Limiters. Limiters enforce hard bandwidth limits for a group or on a per-IP address or network basis. Inside of those bandwidth limits, limiters can also manage traffic priorities.

ue0 (USB Ethernet) does not support ALTQ.
