TDR or similar cable test diagnostics

[Eduardo_Mendiza]

Hello everyone,

I would like to know if the summit series has any TDR functionalities or similiar failure detection features on copper cables. I know the summit series has a run diagnostics command, but, from what I've read, it only tests ASIC and packet loopback.

Cheers.

Ed

Hi David,
Try this: https://github.com/extremenetworks/EXOS_Apps/tree/master/Cablediags

I had found that previously and get the below error
"Downloading to SwitchError: Failed to download image - Error: File could not be unwrapped."

These attempts have been on a X440-48p running 16.2.5.4

David, I ran into this same issue today. I found that by downloading the image via TFTP to my desktop and then uploading it to the switch using "download image x.x.x.x summitX-cablediag-1.1.0.3.xmod vr vr-default" I was able to install it successfully.

Justin,

Thanks for the reply, that worked well for getting the image on the switch.

Unfortunately it still wont run.

440-G1 running 16.2.5.4-patch1-7 and I get the below error.

* Staging-Rack.9 # run script cablediag.py -p 16
cablediag: 1.1.0.3

Do you want to continue cable diagnostics? [y/N]: y
Collecting port cable diagnostic information may take a moment...

Son of a gun, you're right. Just did the same thing for me. Tried it on two different switches, an x440 and an x460, both running 16.2.4.5 patch1-8 and the failed the same way.
