5 years into networking as a software engineer, I feel like I will lose less hair if I avoid hardware programming

Sorry if this is not a good fit for this sub:

I graduated in 2015, and since then I have been involved with some form of Broadcom and using their sdk to configure enterprise routers. I feel that there is a significant hole in my understanding of the underlying system and hardware. I also feel like the knowledge to be gained to work on such systems is probably at a graduate level. Documentation is difficult to parse for most systems and in my current company, it's worse as there is no clear documentation on how the NOS interacts with the Chipset and NPUs. I feel like enterprise networking nearer to the NIC hardware is not for me.

While I can learn switching and routing protocols, I kind of loath having to work below the control plane and in the data plane. My current company's muddled code is not helping either.

Anybody else faced the same problem I am having? What would you recommend that I do?

Destroy me, I am a VAR Salesman for Cisco Networking - Help?

I need some advice from the Networking Gods of Reddit. I am new to tech sales and I am specifically asked to target service providers and we’re primarily a Cisco partner. I am NOT looking for handouts, just some information about how the community prefers to be sold to. Not a Sales “Engineer,” I am the much dumber Account Executive.

Here’s some things I’ve picked up so far:

1. I have no idea what I am talking about

2. I have a 2% chance of telling you something you don’t already know

3. Of that 2% I have an 80% chance of being wrong

4. Cisco is more expensive than most and there’s a big love/hate relationship

5. Most don’t like VARs because the community believes they don’t really offer value

6. You don’t want to talk to me, you want to talk to my engineers

7. You’d like a quick response, quicker quotes

8. Most importantly – LISTEN

I am not asking you how to do my job just merely trying to understand what you want from a VAR and how we could provide that to you specific to networking. If someone was reaching out to provide you a service, what would you like to see and how would you prefer to be contacted?

Mods delete as you wish, I didn’t see any rules specifically against this and looked through past posts and didn’t see too many posts on this topic in the last year.

802.11g channels

Does anyone know how and why 802.11g APs shift channels?

InterVlan Routing with Aruba CX 10.xx

Hope someone can help me out, I am trying to use new gear (Aruba), normally I use Huawei and Cisco Router and Switches, so for me the Aruba CX CLI is something totally new and the configuration are beyond wired. I searched on Youtube and the Hewlett Packard Enterprise forum, but didn't find anything about the configuration of Dot1q and Intervlan Routing on Aruba CX L3 Switches. Can anyone help me out with a little CLI example?

How do I see 802.1x WiFi username and password in Windows 10?

So, I have a windows 10 laptop that I use for school and it's connected to the schools wifi with my credentials. (The schools wifi is secured with 802.1x and it's WPA2 AES) I connected it to the wifi ages ago, and I'm going to get a new laptop soon. The problem is, I don't remember my password. Is there any way for me to see which password I used to log on to my old laptop?

IPv6 to IPv4

I'm "the" networking guy for my group but not "a" networking guy. Also, my little experience is mostly on Dell switches, not Cisco routers. Please keep this in mind while I butcher this request for help.

I have a domain controller on an IPv6 network with a switch and a router (ISR 4321). I have a server on the IPv4 side of the router that needs to join the domain. I'm setting up the router from scratch, so everything is default. In this current environment, there are no firewalls or ACLs. DHCP is not utilized anywhere. Below is the best I can do for a visualization. Not actual IPs, IPv6 is /64, IPv4 is /24. The domain controller is a blade server, so it must connect to that first switch before it can go anywhere else.

I have no control over the two IPv4 networks, I'm not allowed to have a DC on the front-end, no OS based 6to4 tunneling.

Basically I want any server on the 192net side to be able to talk to the domain controller on the IPv6 side well enough to join the domain. The original plan was skip the router and have the DC connect different NICs to each network, but it turns out multi-homing domain controllers is not recommended for several reasons. I thought NAT64 was the way around this, but I can't get it to work (hopefully due to my incompetence).

Option A: Get this to work. NAT64?

Option 3: Switch back to IPv4. We have several reasons for moving to IPv6 that I won't get into. IPv6 is preferred, but if it turns out it's not possible, we can go back to IPv4. Still need to deal with crossing the security networks using NAT or dropping the router and doing some VLAN routing.

So, is what I'm wanting to do possible? Is NAT64 the way to do it? How many licks does it take to get to the center of a tootsie roll pop?

VNC vs RDP over Gigabit LAN

I'm pretty happy with the performance of VNC, but the one nagging issue is that I am using a Intuos tablet that sends pressure data, which VNC doesn't seem to use.

While reading around, I've seen people say that the speed differences between VNC and RDP are minimal over a fast LAN. If that is true and the speeds are similar, I will stick with VNC rather than go down a RDP rabbit hole.

So, will RDP give me a significant speed increase compared to VNC over a gigabit LAN?

Block Dahua Cameras from going outside network

I have 16 Dahua cameras connected to my Unifi gateway. How do I stop them from being able to go out side my network? I basically want them only to be accessed with inside my network.

Subnet Broadcast vs Network Broadcast

It's an apparently trivial question, but how does L2 behave when using those two addresses:

• 255.255.255.255 sends an L2 broadcast to ffff:ffff:ffff
• 192.168.1.255/24 sends L2 frames to ???

Why use different MPLS label at each hop?

I am learning about MPLS and in the various example I came across, provider routers swap labels to a different one at each hop.

Intuitively, if I were a service provider, I'd set up a unique label per LSP.

What are the benefits of swapping the label to another one?
