Hi Everyone,
I'm trying to figure out why my virtual chassis is not linking with other switches.
Before I installed them, I had everything configured correctly and was working properly.
Here is what I have:
All ex4300 switches (7 in total).
All QSFP's are JNP-QSFP-40G-LR4's.
0.0 is core switch. All other #.0 link to 0.0. All #.1's link to #.0 (same room).
SMF is used to link all #.0's to 0.0
All #.0 <-> #.1, and 0.0 <-> 2.0, runs are using the QFX-QSFP-DAC-3M Direct Attach Cable.
0.0 and 2.0 are Routing Engines (2.0 is backup). All other switches are line cards.
VC is preprovisioned.
I did just turn on No-split detection on the master. Had to take down backup and it caused the master to stop working.
It looks like this:
0.0 SMF 1.0
0.0 DAC 2.0
0.0 SMF 3.0 DAC 3.1
0.0 SMF 4.0 DAC 4.1
The longest run, to 4.0, being 200-300ft.
What is working:
0.0 <-> 2.0 (But it uses the direct attach Cable).
I talked to my fiber installer and the fiber was certified before he left. I've tried different patch cables. Nothing.
He did say to change the polarity but not sure how to do that...
Any help would be appreciated.
