Cisco → Re: [Config] HUGE Output drops with no load...

Did you read the linked cisco doc? There is a default QoS policy on all ports, but you'll have to dig to see it. Oh, and I ran across a note saying that drop counter is in bytes, not packets on the 3850. Go figure.

It's not so uncommon to see 10G ports head out to a 1G only device. I hate it, but we work with what we have. (what I really hate is seeing 10G ports running at 1G because they're too cheap to buy 10G optics. Really stupid when I have 2 trays of company branded 10G optics.)

I've seen this, and worse.

I call this Layer 8 sponsored SOP

If the distribution switch is all 10G, and the access switch(es) connecting to it are all 1G... This is very common with companies too cheap to replace their access switches -- they're "working just fine."

My previous employer had a QA lab connected 10G-10G at 1G, because they didn't have any 10G-T adapters, and the patch network throughout the building is all twisted pair. (and likely cat5e given the age of the building)

(This, BTW, is the major drawback to owning your facilities. Once it's built, it'll take a natural disaster to get any of it rebuilt. This was one of the biggest thorns for the NJ office; the company owns it, and it's never seen any infrastructure upgrades. Sure, they buy new computers and switches, but things like communications wiring, power wiring, UPSes, HVAC, etc. never gets touched. They haven't even had new paint and carpet.)

I have a location in NYC that still uses 110-block punchdown panels, and I'm fairly certain it's Cat5, not even e.

HQ spends millions on other bullshit. But new wire job? I ain't got no time fo' dat!

To be fair, rewiring an existing structure is a major pain in the ass. We did it to our last office, because we used what was already there. In this case, all the 20yo ceiling tiles were coming down anyway. (being Class A office space, all the wall boxes have conduit... or they were supposed to - turns out some were added later.)

The worst I can recall is a telco HQ with a spider web of OM1 MM between every IDF. ST connector panels! I was always horrified by that BS. They're a telco; they don't do MM. (of course, the 100FX modules in those switches required it. they used those ancient switches longer than Cisco still had them - had to pull one from a display at RTP when one failed. I want to say they were Cat2920's(?) - fixed config cat5002)

Meh. We use a telecom vendor for wiring needs. In the years I've been there, I've yet to ever hear them say "Impossible" or "Can't do it."

I couldn't begin to imagine the shit they go through to get it done. I have admiration and respect for their work.

The bills we get for some of the outrageous jobs I've asked them to do would scare anyone, for sure. But they get it done.

The new headache is fire-proofing and breaking concrete for new conduit. I could swear some of my locations are about tapped out, and something short of tear and rebuild is probably the only best bet. It makes me appreciate not having become a construction worker!

There's no such thing as impossible... just "too expensive". (which is why that NJ office's computer room has box fans for ceiling tiles.)
