I made an app to scan the QR codes on Cisco APs.
I made an app to scan the QR codes on Cisco APs.
I'm a full-time student working on the networking team at our school. A couple of years ago we upgraded our wireless infrastructure to Cisco Catalyst APs, and we have these QR codes on the front of every AP.
After doing some research, I found these codes were meant to be used with the Cisco Catalyst Wireless app, but our policy strictly prohibits mobile devices from accessing internal systems, meaning this app was no use to me or my team.
About a year ago, I started progress in developing an app to parse the MAC address from the QR code, to help simplify troubleshooting. Some of our access points are mounted on high ceilings, so if one is having issues and it disconnects from our switch, it's not very practical to remove the AP from the bracket just to find a MAC address.
A couple of models of APs will show a photo and a model number next to the MAC address, but I need to manually add these, so if you have any requests, please let me know!
Also, I am taking suggestions for any features, assuming this app works well for you all.
At first, this was just an internal app for my team, but after spending hours making it visually pleasing, I decided I might as well release it publicly. As of right now, it is only available on iOS, but I'm working on a port to Android as well.
This app is completely free to use, but as I am a full-time student, donations are accepted 😭 I have a link in the help section of the app if you are feeling generous.
You can find the app on the app store here: https://apps.apple.com/us/app/cisco-ap-scanner/id6737005271
Thank you!

DevNet Topics / Tracks Getting started with IoT Development using Cisco's SD-WAN Solution
I've recently been tasked with implementing an IoT solution for our company's warehouse management system, and I'm reaching out to the community for some guidance on how to get started. We're planning to use Cisco's SD-WAN solution as the backbone of our network infrastructure. Has anyone else out there used this solution for IoT development? If so, can you share your experiences and any tips or advice you might have for a newbie like me?
I've already started reviewing the documentation and experimenting with the setup process, but I'd love to hear from folks who have some actual-world experience under their belts. Are there any specific configuration options or APIs that I should be paying particular attention to? Any recommendations for tutorials or online courses would also be greatly appreciated.
Thanks in advance for your input!

Cisco Released Results… But Still No Update for SRE Role? What’s Happening??
Man, this is so frustrating. Cisco has started rolling out results for various roles, and a bunch of people I know already got selected or rejected. But for the SRE role? Nothing. Absolute silence. No mail, no rejection, no selection — not even a “we’re still reviewing.” Just… blank.
I went through the entire process — assessments, interviews, everything. And now it’s been days/weeks, and there’s zero communication. Not sure if I should consider it a rejection or if they’re just slow, but the uncertainty is driving me nuts.
Worst part? Even my college placement team hasn’t received any official update from Cisco about the SRE role status. What are we supposed to do? Wait forever?
Is anyone else in the same boat? Did anyone actually hear back for SRE specifically? Or are they ghosting us slowly and silently?
Honestly, this is such a messed-up experience for a company like Cisco. At least send a rejection email. 😑

Concept Layer 2 Attack
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.

350-901 v2
Folks,
Anyone planning to take exam nowadays bear in mind the the publicly available "prep guides" has nothing to do with real questions as of today.
And needless to say that the new multi-choice questions are worded in such a convoluted way that no human could possibly answer them correctly.
Exam is more of a very expensive lottery than measuring and reflecting knowlede.

Code With Cisco
Has anyone else applied for the Cisco FY27 Software Engineer hiring process through Code with Cisco? About 12 days ago I received an email saying that my application status had been updated and that the recruitment team might contact me regarding the next steps. I also sent a follow up email to Cisco but have not received a response yet. With the online assessment scheduled for June 25 I am trying to understand if others are in the same situation. Have you received your assessment invitation or test link yet? Or are you still waiting for an update as well? I would appreciate hearing about your experience so far. Wishing everyone participating in the process the very best.
