    The QFX5120-48T is a 10GbE/100GbE data center leaf and campus distribution switch featuring:
    ● 48 dual-speed 1GbE/10GbE RJ-45 copper downlink ports
    ● Six dual-speed 100GbE (QSFP28)/40GbE (QSFP+) uplink ports
    ● Up to 1.08/2.16 Tbps (uni/bidirectional) of L2 and L3 performance, with latency as low as 800 nanoseconds
    ● A 2.2 GHz quad-core Intel CPU with 16 GB memory and 100 GB SSD storage
    Using breakout cables, 40GbE QSFP+ ports 50 and 51 can be channelized into four 10GbE SFP+ ports each, increasing the total number of 10GbE ports per switch to 56.

    QFX5120-32C

    The QFX5120-32C is a compact 100GbE data center leaf-and-spine and campus distribution switch featuring:
