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:

100 Gb One QSFP28 port with one of the following:

Note: These ports do not support 1x100Gb
For information about configuring partitioned ports, see the ExtremeXOS 31.1 Command Reference
