Looks like stuck in a boot loop. I'd suggest trying to perform new SW load via USB. I'd also suggest using 12.3R12-S6(latest) instead of 15.1, but that has nothing to do with your current situation;...

This is really a question you should be asking whomever your Juniper reseller/partner would be, or else your local Juniper sales team. Why not QFX5110-48S (or similar)? 4 x QSFP28 (native 100GE or...

Is the ESX Server also in 192.168.168.0? If yes, then all that is required is VLAN 10 (I might have used VLAN 168 instead. It is just a number.) to be a member of tagged trunk between EX3300 and...

yes, the new ESX behind EX3300 will be in same network 192.168.168.0 as DMZ on MX. I will schedule that after hours closer to the end of this week and post my findings. Thank you all so much for your...

Hi, I'm a bit confused on what the recommeded upgrade path for this scenario. Do I need to upgrade to 14.x something before going all the way to 15.1R6? Thanks!

Actually in this case you can upgrade directly from any 12.3 release to any 15.1 release. I might suggest you remain on 12.3 for a while longer, as 15.1 has been shown to not be 100% stable with older...

The QFX5110-48S has 48 x SFP+ ports and 4 x 100G QSFP28 ports. All SFP+ ports can run both as 10G and 1G ports.Should fit your requirements :-)

There is no reason, as no knew functionality or fixes, to even consider 14.x for the legacy EX products. In my experience 12.3R9+ has been guite stable with these products and at this time I only...

How many uplink do you have between MX and EX? Case 1 -if it is only 1 uplink then, you need to allow all the vlans on MX side as well. As per your description you seem to have allowed only vlan...
