The QFX5200-32C device ports, (
100 Gbps QSFP28 transceivers
40 Gbps QSFP+ transceivers
100 Gbps active optical cables (AOC)
NOTE: For interoperability with other QFX Series switches, ensure
auto-negotiation on the QFX5200 is disabled.
40 Gbps AOC
QSFP28 direct attach copper (DAC) cables
QSFP+ DAC cables
QSFP+ to QSFP+ direct attach copper break out (DACBO) cables (100 Gbps breaks
out to 50 Gbps or 25 Gbps)
QSFP+ to SFP+ DACBO cables (40 Gbps breaks out to 10 Gbps)
For downstream traffic, the QFX5200-32C has 32 physical or 128 logical ports (32 x 4)
that can be used for port channelization. The 100 Gigabit Ethernet ports can be
channelized using breakout cables either to 2 independent downstream 50 Gigabit
Ethernet or to 4 independent 25 Gigabit Ethernet ports. The default 100 Gigabit Ethernet
ports can also be configured as 40 Gigabit Ethernet and in this configuration can either
operate as dedicated 40 Gigabit Ethernet ports or can be channelized to 4 independent
10 Gigabit Ethernet ports using breakout cables.
4— 32 QSFP28 ports
