What Are You Doing Right Now

QoS knowledge was, in the 1990s, considered so basic that you had to do a test on it that gave you zero credit in the MS cert world, other than allowing you to then go on to other certs. Today, you get a Net+ for that same work. The bar has lowered a bit. But that it is entry level "universal" knowledge that you should expect from everyone hasn't changed. Even helpdesk people, while maybe not confident that they know the answers, should know what QoS does any why and when it would be useful.

Oh, ha ha. He thinks that the LAN is saturated? Or he thinks that your outbound WAN is saturated?

He thinks that the LAN is saturated.
How the heck is that happening and why hasn't it been fixed? He actually thinks that your switching backplanes are beyond capacity but hasn't addressed it? How does anyone work?

Part of the point of at least one of the articles was that instead of bandaiding LAN saturation with QoS, you should fix the LAN.

We have added switches because the switches that were put in when I showed up were not performing what we needed and were difficult to administer. We since then upgraded to newer and faster switches and network performance has improved. However, he still insists on VLANing EVERYTHING!!

Well the VLANs might explain the saturation. They cause that.

Was going to bake some tilapia but decided that I wanted some sushi. Real sushi, not sashimi. I don't really do fish sushi, but I like vegetable sushi.

He can VLAN all he wants. But that does not change the fact that QoS on and entire VLAN is not correctly prioritizing the voice traffic.
It is prioritizing all of the traffic on the VLAN. Which includes the broadcast traffic and dns and dhcp and sip as well as the rtp that actually carries the voice traffic.
It is a misconfiguration based on stated intent.
You boss is wrong. Feel free to send this to him.

Can't. Upvote. Enough.

Just caught up on SW for the day, one of the fastest catchups I've ever had after a day offline. It's as if no one was there. And quite a few posts that I stumbled on had zero replies after being up most of the day.

@NerdyDad How many phone calls are active when this happens?

And is the audio an issue bidirectionally or just in one direction? Is there QoS on the WAN?
-
I'm assuming that he knows that if this is happening it would be on extension to extension calls, not only on ones going to the outside.

Made this point to someone on SW today.

@scottalanmiller That's because I was not there
