Hi Friends,

We have been reported, in our network, our teleprescence device is rebooting  very often. After the intial  troubleshooting, it has been decided as Issue is occuring due to the lan Network

i am doing an Lan Audit to find Any   issue with Lan.

As of now, layer 2 is fine.

I am running an layer 1 test now.

When i did a cable diagnostics, i got the below ouptut, which is very different.

Could you  guys confirm whether cabling Is normal here.
