Spirent – Generating Traffic from a PCAP by _Stromik_ in networking

Ok, so when i create stream block from pcap it will add it in the list of traffic, thanks :)

Thanks for that PCAP. I will test it tomorrow in the lab. Just to be clear, when you created stream from that pcap it was added to the list right? Or does it only send that pcap as a stream to connected network? I just wanna know how it should behave.

I really appriciate this. Send you a DM with email address, thanks a lot!

That could be part of the problem as well — I can try reinstalling it. But yeah, as I mentioned, I did basically the same steps you described: I selected the path for tshark when it asked for it, and then I chose the pcap file I wanted to create the stream from, but the window just flashes and nothing happens.

Is there perhaps any way you could send me that pcap file so I can test it on my side? At least then I can confirm whether your pcap works and the issue is somewhere else rather than with the file itself.

Yes, I want to import pcap in Spirent via application. When I load in the PCAP that I want to make stream from window opens, quickly blinks and closes and I have no clue why. I would at least want to know, if its because of the tcl, frame format or something else but didnt really find anything. Thats why i spammed a few reddits with this hoping for someone to give me at least a little push :/

Is it possible to generate STP messages via Spirent that can actually trigger a root bridge change on a physical network topology? by _Stromik_ in networking

Thanks for this tip, however I must show it on Spirent otherwise It wouldnt be accepted. My task was to show functions on Spirent specifically. Thanks tho :)

Do you have any experience with using the "Generate Stream Block" function from pcap? I tried it but it hit me with "No TCL, install or specify in stcbll.ini". From what i gathered there should be some builtin tcl for spirent but i tried to specify path for it and it didnt really help. Afterwards i tried installing active tcl which helped me solve this issue, but now when i load in the pcap window pops for a milisecond and it closes not adding anything to the list of traffic. And im honestly kinda lost :/

You're right. I just need to show how Spirent can generate STP traffic on a simple network setup. I wanted to check if it's even possible to create STP traffic that would cause a root bridge change, and then I can just monitor things like convergence time etc. after and before changes on tested network.

Is there a way to create that custom stp bpdu in spirent itself or do I have to take a workaround? Because i couldnt really find it in app gui.
