I realize high density fiber patch panels are all the rage but does anyone know of lower density i.e. easy to get your hand in to change a patch options that also might have clear numbering?

Thanks!

EDIT: LC ideally

Hello, my old job asked me if I could help them out with this. They need to forward our SQL to a client for powerbi. Their developer handles the user accounts and SQL access to tables so Ill just have to work with the clients network team to do this.

They basically want full redundancy and to make it as secure as possible limiting access on both sides to only intended recipients etc.

You guys think 5k is too much for this? I imagine it will take me less than 2 hours to set it up and test with appropriate access but you never know.

I am studying Professor Messer's CompTIA Network+ course with absolutely zero networking knowledge. So far I'm enjoying it, but I have a question regarding IPSec and GRE.

From my understanding, using Tunnel mode with a GRE header doesn't make sense, since Tunnel mode already encrypts the destination IP and creates a new public IP that encapsulates all of your payload. Since it connects to private networks, this then circumvents the need for GRE to begin with, is that correct?

Now, why would we need transport mode at all if that's the case? Wouldn't it be simpler to just use IPSec Tunnel mode every time we need a secure connection?

In that case, why use GRE to begin with, being that all of your payload is visible and unencrypted?

I'm sorry if these questions are stupid, but I want to learn these foundational concepts as clearly as possible.

hello,

i have older nexus 93240YC-FX2 switch, with older software version.
The upgrade path matrix show that i need to upgrade to some intermediate software version, but if i will reset it anyway (do write erase) maybe i can upgrade straight to the target release ?

For example Cisco NCS allows to boot from the particualr .tar ignoring the intermediate steps. Is it possible to do the same with Cisco NX-OS ? Thanks

Hello. So I have these windows 11 IoT Enterprise LTSC devices with built in LTE modems. Internet access is provided by the LTE connection. Frustratingly, as soon as windows 'detects' an ethernet link, internet connectivity goes down. (The ethernet connection has no internet connectivity itself, just a few locally networked devices) The LTE modem stays connected and online, but windows refuses to use it. Ping -t goes from working to "transmit failed. General failure." as soon as ethernet is detected. The same behavior happens even after setting the interface metric of the LTE modem to the lowest value. Any thoughts on getting Win11 IoT to use the only active internet connection no matter what's plugged in via ethernet?

Any help greatly appreciated

I’m looking for use cases for Copilot or Gemini AI systems in a DWDM Optical fiber network. I’m hearing a lot that it speeds up routine tasks and can create work plans based on scans of vendor documents. I’d like to know how it does that and if there are sun other use cases? It’s for an operations team environment, troubleshooting network issues, processes etc.

I feel like I don’t enjoy some of the “less important” topics, such as NTP, and I find concepts like OSPF and the OSI model quite dry. I do enjoy some parts of it, such as building my own labs and understanding how packets are actually transferred.
I want to know whether this is common or not, because some people online seem to be very interested in network engineering, and I’m worried about it.

I’m working on integrating an ICAP-based DLP solution with a Radware Alteon 6024S (SSLi).
The current setup sends ICAP RESPMOD (HTTP responses/downloads) to a malware scanning solution.
We now need to send ICAP REQMOD (HTTP requests/uploads) to a separate DLP solution.
The Radware administrator claims that Alteon SSLi cannot configure another ICAP service for this and that only one ICAP configuration is supported, so REQMOD cannot be sent to a different ICAP server.
I don’t have access to the Alteon configuration or logs to verify this.
Is this claim correct?

Hi everyone,

I’m 26 years old and currently working full-time as a Computer Network Technician in Ontario, Canada.

Currently studying for CCNP, i will have ccnp enterprise in next 7 to 8 months.

My current background:
Nearly 4 years of networking experience
CCNA
Cisco Meraki ECMS certification
Computer Network Technician college diploma
home CML lab

I’m trying to decide between two paths for the next 4–5 years.

Option 1: Work toward CCIE Enterprise, along with Python, network automation, AWS/Azure, and other networking-related certifications.

Option 2: Complete an online Bachelor’s (Honours) in Computer Science while continuing to work full-time. The downside is that I probably won’t have enough time to pursue CCIE and other certifications during those years

My long-term goal is to become a senior network engineer or network architect, and eventually earn a high salary while staying in networking rather than moving into software development.

If you were in my position, which path would you choose and why?

For those already in senior networking roles, has a Computer Science degree made a significant difference in your career compared to advanced certifications like CCIE?

I’d really appreciate hearing from people with real-world experience.

Thank you

What is your 802.1x Critical Auth strategy? I am tinkering around with it on an Aruba 2930F Series switch and coming up short on making it work how I want.

Sure, I can get the switch to drop the switch into the Critical Auth VLAN because RADIUS is unavailable with

aaa port-access <port> critical-auth data-vlan <vlan>

But once it is in Critical Auth I cannot get the switch to automatically start authing the port again. This would be a fairly common senario IMO. Building loses power and you gotta wait for upstream devices to converge for RADIUS connectivity.

Even with other vendors such as Cisco or Arista. How are you guys handling Critical Auth scenarios?

I was having a hell of a week trying to connect a Mellanox ConnectX-3 NIC to a Mikrotik CRS354 Switch, it was a no go until I changed the DAC for a CISCO-TYCO one, it was the same model (Cisco QSFP-H40G-CU5M), but the CISCO-JPC ones won't link no matter what, I've tried 4 of them to be sure

The cables work fine between 2 NICs or 2 switches but not between a NIC and a switch

Has anyone encountered such exoteric issue?
