Hi guys,
So I faced a really weird problem. I have a QFX5110 switches bundled into Virtual Chassis. And I have a standalone Cisco Catalyst 3560 switch.
I'm trying to setup a simple trunk between them and I just can't The biggest problem is that the interfaces doesn't even come up on both ends!
I tried to do command
show interfaces diagnostics optics ge-0/0/26
But it doesn't even get me any output !
What is going on ?
Any ideas what might be wrong, why even Layer 1 doesn't work ?
What is funny when I will take the cable off the Juniper and put into Cisco switch, everything between Cisco's just work.
Here is the details on Cisco switch.
