Is there any software for testing the switch?

Question

Iron

There is a very large box of stupid unmanaged switches. I want to weed out from the heap only what works stably, the rest is junk.
I searched in the open spaces, I found one comprehensive program, but it is like a pentest, it is configured terribly and is expensive.
I would like to understand from the test:
1) Are all ports working
2) Real throughput
3) Poppy table ceiling, etc.
How to test the switch?

Answer 1

In any case, you will have to assemble a stand from several traffic sources / receivers. It can be either Mikrotik or Comp . The cisco also has an IP SLA , but it's still more of an application level test, not a channel one.
Again, there are speeds of interfaces, and there are speeds of logic inside. Not all pieces of iron will give out the peak speed of the interface under load on absolutely all ports, and when loaded on a pair of ports, even the most deshman will most likely give out quite a lot. Therefore, it is necessary to build a stand with a sufficient number of loading ports.
Poppy limit can be checked with scapy. Some knowledge of python programming is required. Generate random outgoing poppies in a loop, flood them, and send pings in parallel. Another participant just sits and listens. When he also starts to hear pings, the poppy table overflowed and our switch became a hub :).

Answer 2

With unmanaged switches it's harder. Try SNMP, I think you will get most of the data. Well, to get real data, collect a laboratory.
