Overview
The port panel of the QFX5220-128C consists of 128 high-density 100-Gigabit Ethernet quad small
form-factor pluggable solution (QSFP28) ports and the management panel. The highly flexible ports support
100-Gbps or 40-Gbps port speeds; 100-Gbps speed is the default, 40G-Gbps must be configured. The
QFX5220-128C supports channelizing the QSFP28 ports to 4 independent 25-Gbps speed interfaces.
The switch has two dedicated 10-Gigabit Ethernet ports and when the 128 ports are configured for
40-Gbps speeds, 32 of the 128 ports can be channelized to 4 x 25-Gbps. See Figure 6 on page 33 .
