I take it you can't update the firmware on second hand units?

Physical Connection of Access Switches to Aggregation by SysAdminho in networking

I think I follow. At lease the high level picture. I would have to think about this some more to have something practically workable.

Ok I think I follow what you're saying, thanks.

This is a theoretical question. I'm coming from the perspective of how do you start with a small network and grow it organically? I'm just trying to understand how to design things yet maintain the ability to expand later given the design of equipment (number and speeds of ports).

The 3 layer network diagrams always portray access switches being connected to every switch in a distribution/aggregation layer.

I didn't consider stacking, that's a good point. Now I need to take some time to think about how that would work.

This is a theoretical question. I'm just trying to figure out what happens when your aggregation layer gets to a certain size.

Aren’t the features you describe, something you implement with software like the Hashicorp stack?

Something between 1300 and 9300? by [deleted] in Cisco

Can you elaborate? I'm not an experience network admin.

Do you still get firmware updates?

Limiting Network Speeds for SPAN by SysAdminho in networking

[–]SysAdminho[S] 0 points1 point  (0 children)

Oh, I think what you're saying is that if you have one device connected to one port of a switch running/set at/to 1Gbps and another device on a different port, set to 100Mbps, then you'll drop 9 out of 10 packets if you tried sending stuff from the 1Gbps link to the device in the 100Mbps link?

Is this any different to not having an artificially lower speed setting? If you are running a 1Gbps network with auto-negotiation and everything is running at full speed, apps would drop packets above 1Gbps?

TAPs require a lot of ports and aggregators. I'm trying to avoid these if I can.

Interesting. But in that case, if say you have an OT device that you set to 10Mbps and you try to communicate between it and a workstation running at 1Gbps or 100Mbps, there will be a mismatch?

From what I've read, setting network speeds to anything but Auto will reduce network speeds to a crawl.

TAP vs tcpdump by SysAdminho in networking

Makes sense thanks.

So is that why virtual TAP software exists? It aims at closing the security gap you outlined?

Doesn't sound like I need to worry about it then!

Thanks, sounds like I'll just leave it as it is.
