Configuring QoS on a Edge Switch 48 Lite
-
QoS can't help though, as it's simply adding more to the network payload that the switch would have to process.
QoS issues on the LAN are something else entirely, like a poorly designed network, I'd really look at the switches and see if 1) they are in fact saturated 2) that DSCP tagging can't be enabled
-
I guess a better thing to do would be to show us a network topology so we can see what's going on. Hell I need to do the same thing! My head hurts when we talk QoS.
-
Worth mentioning, but these switches have 70 Gbps throughput (which ain't shabby).

That is totally not how anything works.
Of course QoS can help. That is the entire point of QoS.

@jaredbusch would you agree that having QoS enabled on everything on the switch is not helpful?

Each port is still only 1Gbps. That is where the QoS is important.

No I do not agree with you. Having QoS enabled is 100% helpful. That is the entire point of the solution.

@jaredbusch I would only have QoS enabled for specific type of traffic (with DSCP tagging) using blanket QoS has never been helpful in my experience as everything than gets "top priority".
Disagree with me if you want, but tagging specific types of traffic offers better QoS than using blanket functionality.

There is no such thing as "blanket QoS". QoS is always something configured. With a GUI wizard, or by hand, but still configured. No wizard I have ever used give all traffic the same priority as that would defeat the purpose of it.
You are arguing in a cirlce with bad information.

Has anybody set QoS on the switches? Trying to prioritize VOIP on reported saturated switches. I can see from here https://dl.ubnt.com/guides/edgemax/EdgeSwitch_AdminGuide.pdf#ConfQoS.indd%3AAnchor 1%3A285 the edgeswitches do offersome options but not clear on what works better as I have not done QoS on switches before.
It is all configured in the "Legacy" interface of the Switch. I've never used any of this yet.

Looking at this all, I would use
Class of Service->IP DSCPto set the various priories.
Then on the interface tab, change each port form the default trust VLAN to trust IP-DSCP
-
On the otherhand, if you have a voice only VLAN, leave that all alone and specify the Voice VLAN in the Auto VoIP settings.
-
Don't have any vlan set on the the switches, so probably best bet would be
Class of Service->IP DSCPthen right? -
@JaredBusch you've obviously never seen QoS at the Port level for every switch having same exact settings and having to deal with that headache.

Lots of people don't know WTF they are doing and set shit up wrong. That does not invalidate the thing they were setting up. Only their implementation of it.

But you do still want to look at verifying saturation.

@jaredbusch "Lots of people don't know WTF they are doing" Im sometimes one of those people. But I think the problem is due to a lack of proper explanation, training materials and scenarios. Not talking about you specifically but saying in general.
