Port Partitioning

On some ExtremeSwitching switch models, you can configure QSFP28 and QSFP+ 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:
