RIP in peace

It’s called Telegraf / Prometheus / Elastic. Building your own is crazy.

I will miss "Bad" 👮 Greg grilling Cisco

thank you Greg.

Wish you the best Greg in your next chapter!

Thanks Greg. Been reading for years. Good luck with your future!

The end of an era, take care Greg.

All the best Mr Ferro. Your blog and the podcasts helped get me out of the rut I was in at the start of my career, and for that I am extremely grateful.

Relly good stuff, thanks

I dont see how paying 5 times more is beneficial for customers

Dark information is the best information.

Think outside the box. if you're interesting enough they're using your power supply for egress. How many frequencies can you nest in a laser? Are you monitoring your local airwaves? Am I crazy, or are you just not that interesting? Check your logs on a Monday? lmao

Long time listener but i was on google podcasts which didnt have a section for commenting or like-ing I couldnt fint it atleast.

Man i luv Heavy Strategy. Im not sure what that says about me. I like conflict with smart people maybe?

I think it would be more of LISP-vxlan than EVPN-LISP... (controlplane-encap) I guess using my logic, pure LISP systems would be LISP-LISP...

Great insights from OpenColo on leveraging Nokia's SR Linux network OS for automating BGP peering! It's impressive to see how SR Linux's robust features enable predictable automations and efficient telemetry ingestion for monitoring and operations.

‘Zero trust’ is marketing propaganda. It is total BS. Authentication and re-authentication at the user level and various system component levels has been around for a very long time.

NSX 3.x+ uses NSX-T as its base, so Geneve. "NSX-V" is dead.

With american nuclear power plants, a safety check by the NRC found over 100 instances where critical parts ( valves, gauges, switches, etc) had been replaced with cheaper off the shelf, untested, un- certified parts, many of which were critical to safety! And this was not an in-depth examination of the reactor systems, but a look at easily accessible, SAFETY CRUCIAL COMPONENTS! Another plant was found to be directing radioactive water leaking from a 12" pipe flange into a floor drain, with plastic sheeting, secured with some duct tape, to a wooden broom handle! Sure, we could make nuclear powerplants safer, but as long as they are operated by corporations with the bottom dollar in mind, there will never be safety first! And all these wireless sensors and systems would have to be tested to the demanding circumstances of nuclear radiation! A neutron goes thru nearly anything, and gamma rays destroy both cellular structures and electronics. Hardwired systems are the most substantial and abuse resistant. Even robots failed in the high radiation levels at chernobyl and the huge levels at Fukushima, a million Sieverts out side the reactor buildings, and 3 sieverts is a lethal dose! Now plutonium is found on every land mass, and cesium137 is found from surface to the ocean floor! Strontium90 was found in every scottish childs teeth tested along the coast and near the dounreay reprocessing plant!! This will kill all life on earth, the ocean of peace is now nearly sterile! Salmon are decimated, none at all returning in many rivers on the pacific coast, anchovies and squid and feeder fish industry's are shut down!

thanks for work - previous video about services very informative

great video

Thanks a lot for the great content! 🙏

Thank you Ethan and Ed. Ethan - for asking great questions, Ed- for giving great answers 😁

This fellow also side hustles as an auctioneer.

ive seen unwanted shadow hosting without approval. i dont like intrusion its remote and a dozen or so operators, i spoke to watchdog , HLS Nisa Icann and 20 in total aspects cause i dont support terrorism how do you relax this?? im terrified and want no Mitm indecency...🎉😮..Thanks for any feedback

Thank you for the great interview/tutorial. I liked this format a lot, when someone asks for clarification of specific things. Thanks a lot.

Thank for for this short series. It's good to hear it clearly laid out like this.

Because every vendor is trying to lock us in with their own vendor solution which leaves every organization having to develop their own solution

My fav show, heavy strategy!

Super powerful tool 👏

Ironic. Eric, I just bought your python book earlier today.

CISA, the sister agency to the TSA. Both are theatrics over substance.

In type 2 Seq number is used to identify is the latest one incase the same mac updates comes

This is a fantastic BGP series. Please when will the next set of videos be released? Again thanks a lot Russ White and Packet Pushers

beneš network & butterfly are both 5 stages - but what will be the different ? within them?

Checking back on this, Stability AI may have something to say here.

The biggest problem is people applying with cvs which claim xperience over a massive range of technologies. Many have exposure and are not actual experts. Companies sifting their resumes then make selection choices based on generic keywords due to the volume. Recruitment agencies have the same problem. In the end people who are capable and have not misled people are shafted. Quite how we get found these scumbags is beyond me. Its dog eat dog.

Thanks so much Ed. You have simplified everything for me. You are the best trainer i have learned from 🥰

As a long time network/IT guy, I yelled "yes Grerg!" when he pushed back hard on emotional intelligence. Big thumbs up!

Beautiful explanation. Cleared a ton of my doubts. This praise doesn't just refer to this video; it actually refers to the entire series. Thanks a lot!!

Generally helpful and reasonably clear, but at 21:30 when a butterfly topology is shown to be folded and a different view is shown - WHY, of WHY are different colors used (and it even looks like two groups have the same color)? it would be SO much better to keep the same colors in the transition animation.

As far as the different feature sets baked in (again only focused on Cisco Nexus) - Microburst detection can be useful in some situations. AFD/ETRAP/DPP are all very unique ways to work around being fair to bursty traffic as well as being fair to elephant and mice flows. As far as the gPB telemetry, I've seen a large uptick in this becoming more important. Primarily with the way this data can be used with no CPU overhead to deliver non-sampled full flow records directly to a collector. Built in tools such as Nexus Dashboard Insights can use this data beyond troubleshooting these days to do things like dependency mapping using connectivity analysis allowing you to stitch together security policy based on what's actually happening versus limited logging capabilities of these switches (they are not firewalls and are limited by control plane policing usually). The main problem with telemetry is scale of the collector and Cisco's NDI app is limited to 20,000 flows/sec.

Some corrections on Cisco's Cloud Scale ASICs (since that is what I primarily work with in ACI mode) - They do not use that additional ASIC to do VXLAN encap/decap with routing. That was one of the main purposes of them developing their own silicon. Only the Gen 1 N9K switches used the Broadcom dual ASIC hack. Regarding store and forward versus cut through, with the N9300 for example, it depends on speed of ingress/egress. Given it's a fabric, this makes the most sense. i.e egress interface is same speed or faster it uses cut through and if there is a CRC error, it has to "stomp" the CRC by changing the frame FCS letting other egress ports know that it has already been forwarded but it has errors. If the ingress interface is slower than egress, it defaults to store and forward. I imagine this is the opposite of what you described in relation to speed mismatch. In this case it seems they are smoothing out the difference in signal rate on egress by using the buffer. This of course is different than congestion-related speed mismatch.

Companies need penalties when they get breached. Today they sweep it under the rug, and give everyone credit monitoring.

Being certified no longer means being capable. SANS can not be trusted because they are in the business of certifying. Their interest is not in growing skills and helping people become capable but being certified.

Kubevirt? Obvious advantage is that you get Kubernetes networking (NSX replacement).

Very useful information. Thanks a lot.

Great discussion y'all! Thanks for sharing your insights on what is to come 🙂

Great explanation!

Great content and thanks for sharing. I would suggest slow down a little bit, it is difficult to see the result of the playbooks specially when you are new to Ansible
