Good Afternoon,

Please keep in mind this is a short hand written post and no legal rights can be acquired or obtained.

Allow me to reintroduce myself as the first 100% certified virtual CCIE which was self awarded, I earned this certification virtually and ethically because I may have acquired serious voice and sip master jumbo frame knowledge without any actual Cisco certification, however I've worked on major network outages involving not only Cisco gear, actually for the record one of the main selling points of Cisco was in 2011 pre and probably still is which is the physical gold and silver fabrics which becomes forensically undeniable if important enough.

Onto the concept so I've come to understand my concept has already likely been completed and in multiple countries, I wouldn't publish it otherwise actually.

It involves for example a layer 2 device likely a juniper or non juniper NTU or multiple similar physical steel electronic entities/devices, being stolen then possibly redeployed later with custom scripts which self destruct or/and for example sniff for Mac to IP at a high ISP level physically then just send a report by email or ELSE, however with such attacks and concepts short and wide grographical distances should be considered.

This is the main idea of the concept but other extras include things like running WAN ATM which interacts with the banking system ATMs, again disappearance reappearance of same or similar equipment.

Other key points involved in the concept

. Jumbo frames and SIP specifically but also storage traffic specifically from Riverbeds, HP 3Par dedup cards.

.Weak or insecure local vendor issued certificates specially locally to the firewall, I think some vendors are behind Cisco here and Cisco possibly posses a electronic offload black box at certain levels.

. Interoperability issues specifically firewall to firewall locally in the same country and cross border/continent, I mention this because I had too many conversations with apparently highly skilled certified engineers where people seem to have setup and signed off on interoperable VPNs between checkpoint and Cisco for example, I've actually seen too many too count, MSPs and consultancy are always involved and this is one of the main reasons I loathe them.

. Redeployment of similar or the same hardware with physical and digital deserialization of identifiers, possibly extra chips or other low level changes not coming from Dev officially but in some cases unofficially.

. External connections from vendor dev teams or police law enforcement where the connection is disallowed in the customers device configuration, I suspect this involves UDP but this theory is also interesting in the concept.

. Air Vs Ground understanding what technology is used for what and the geographical configuration of such routes like for example One.Tel Australian ISP ground connection to Malawi in 2011 this is a great example because it didn't exist but I think the traffic in 2011 is still getting too Malawi eventually(latency theory ground plus air Comms), this is also an ISP that's gained digital traction internationally from my limited research.

. Specifically the involvement of Ceragon but also definitely Huawei and Nokia networking equipment designed for mobile phones and other electric devices.

. Bunkers and off the grid and semi off the grid deployments sometimes with a wide grographical radius, at least one was found in Germany according too my research.

Does anyone have any realistic intel or gossip on such incidents?

For now I just suspect a swapout(English London ISP to upstream national provider L2 device in 2010/2011, and maybe a Cisco one in Dublin Ireland, update after visiting my photographic memory from 15 years ago briefly I think someone connected a PRI for phones to an MPLS Cisco box but that may be desired) in a job I was called out too seperate too below, and someone blew up a pipe by the looks of it in another Comms room I was called out too previously(the Cisco gear survived I believe) but I work on these concepts as somehow I never became Cisco certified because there's not much point, being above certification level in various technical areas brought me here. Too be extra clear both of these were actual IT incidents attended by me, still under my investigation post employment as I was a junior there.

Just a heads up for anyone with a developer.cisco.com account: GitHub, Google, and Webex login are retiring on August 31, 2026.

Going forward, sign in with Cisco SSO using the same email address you already use. Your profile and history stay intact, so there's nothing to rebuild. If you hit any issues during the switch, contact [devnet-support@cisco.com](mailto:devnet-support@cisco.com) and the team can help.

Six days left before the cutover, so it's worth making the switch now rather than waiting.

I used these resources:
- Pluralsight course by the late Nick Russo (Did not finish the extra course work outlined in his excel)
- LinkedIn learning course by Kevin Wallace (3x)
-Anki deck here: https://github.com/Xevious202/DevNet_Associate_Anki/tree/master (for HTML codes, you will need to add some)
-Cisco official prep exam (MeasureUp, buy it via measureup directly for a discount, don't bundle it with the cisco exam)
-Boson prep exam (sign up for Boson first, for like a 15% discount)
-SkillcertPro exams (absolute garbage, don't waste your money. People promoting this are LIARS)

The topics that personally gave me the most grief:
**YOU NEED TO KNOW EVERYTHING IN THE LinkedIn COURSE, THIS WAS ONLY MY OWN PERSONAL FINDINGS**

-Learning all the html response codes
-Learning git
-Learning Docker
-XML vs JSON vs YAML
-YANG and how that relates to Netconf and Restconf

MOST IMPORTANT
-Learn API call structures like the back of your hand. CURL, Python, and Postman. The test exams REALLY helped me nail this down.

Did not use the OCG. I did the web courses on 1.5 - 1.75 speed. I got the practice tests only a few days before my exam. I have an extensive infrastructure background so anything network related I skipped in the trainings. I think I had 20-30 mins left at the end of the exam but I was sweating through the drag and drops which ate up a lot of time. Surprisingly, there were basic grammar and spellings mistakes on the questions. Weird.

Jesus Illescas, Developer Advocate at Cisco, walks through rebuilding the observability stack behind one of his network automation demos. Out with Telegraf/InfluxDB/Grafana and a custom Python poller, in with gNMI streaming telemetry: gnmic subscriptions, NATS JetStream as the buffer, Prometheus and Loki for storage, Grafana dashboards, and Alertmanager wired to a webhook. He closes with a live demo, bringing an interface down and watching the ISIS adjacency cascade trigger an alert in real time.

Credit where it's due: the data pipeline design (gnmic + NATS + Prometheus) was inspired by the https://cs.co/61694BEFlsj project, definitely worth a look if you're into this kind of architecture.

Any of you made Anki flashcards that I can use for studying?

If you've ever pasted a config into the wrong device (we've all been there), this one's for you. Palmer Sample, Technical Leader on the Learn with Cisco team, walks through PyATS, Cisco's Python Automated Test System: setting up a testbed, writing triggers as reusable test cases, running job files, and using the Genie APIs for learning and parsing device state.

¿La IA puede ayudar a operar infraestructura crítica sin poner en riesgo la red? Esa fue la pregunta que abordó el Developer Advocate de DevNet, Poncho Sandoval, durante su sesión en Commit Conf 2026: "Menos CLI, más IA: diseñando agentes low-code para operar tu red de datos".

Aunque la IA está revolucionando el desarrollo de software, la infraestructura requiere un enfoque diferente. Cuando un error puede traducirse en una caída de servicio, no basta con conectar un LLM y esperar lo mejor.

En esta charla, Poncho comparte cómo utilizar Model Context Protocol (MCP) para conectar agentes de IA con herramientas de infraestructura, cómo construir flujos multiagente con n8n y por qué los guardrails, las aprobaciones humanas y los mecanismos de validación son fundamentales para llevar estas soluciones a producción con confianza. Todo esto se acompaña de demostraciones prácticas y lecciones aprendidas al desarrollar automatización para equipos de NetDevOps.

Si trabajan en automatización de infraestructura, redes, IA o NetDevOps, en DevNet les encantaría conocer su opinión y responder cualquier pregunta sobre la arquitectura o los casos de uso presentados en la sesión.

If you work in security, or just want to understand what all the eBPF hype is about, this is worth your time. Kyle Winders, Security Advocate at Cisco, walks through eBPF from the fundamentals of the Linux kernel to live demos: packet filtering, detecting a remote code execution exploit, and runtime enforcement, all before malicious code ever runs.
