Port Partitioning

On some ExtremeSwitching Universal switch models, you can configure QSFP28 ports either as single ports or as multiple, partitioned ports. In a partitioned port, with appropriate cabling, the original physical port can accommodate multiple data lanes at lower bandwidths.

The following partitioning options are available:

  • Two 50 Gb ports
  • One 40 Gb port (default)
  • Four 25 Gb ports
  • Four 10 Gb ports
Note: These ports do not support 1x100Gb
