The copper optic warning is 100% based on physical limitations, nothing else.
People have “forced” optics into places they should not go, with poor results.
If you need more than a few 10GE-BaseT ports, then yes your best approach would
be QFX5100-48T. I would still recommend staying away from

Hi guys,
thank you for your responses.
Sorry, my first email was not clear enough that I require Base-T (copper) ports.
QFX5110 etc. are looking great on paper, but with copper optics the docs are
saying:
###
Caution
Do not place a copper transceiver in an access port directly above or below
Have you considered EX4600?
It is like a QFX5100 but with less feature support. I have 2x in an MC-LAG
which has been great, but it supports Virtual Chassis too.

I would highly recommend going with QFX5110 instead of QFX5100 – same
everything but QFX5110 offers L3 VXLAN which QFX5100 does not. I know you do
not need this today, but down the road who knows. EVPN/VXLAN appears to be the
new architecture for most networks, plus QFX5110 has QSFP28

I have 2x QFX5100-96s for an L2 core in a VC. Primary function is
mitigating exuberant computer research traffic; I have some unique
firewalls on every interface uplink to an EX2200/4200. Twice a year we
also push 8.5Gbs for 180 minutes to image systems on an EX4200 stack; no
other traffic notices
Hi all,
we have migrated our core (8-10x Racks, BGP default route, LACP to the ToR,
VLAN, L3, nothing fancy) to a VC of 2x 4200-24T with 12.3R12-S9. 12.3R12-Sx is
a recommend version for EX4200. We have had a kernel panic (no JTAC) and I am
not confident with this old setup anymore.
