Port Partitioning
On some ExtremeSwitching Universal switch models, you can congure 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:

Ports 1-27 and 29-32 with one of the following:
• One 100 Gb port (default)
• One 40 Gb port
• Two 50 Gb ports (Switch Engine only)
• Four 25 Gb ports
• Four 10 Gb ports
• One 1 Gb port with the 10506 QSA adaptor
(both Switch Engine and Fabric Engine)
Note: Port 28 cannot be partitioned and is
40/100G capable only.
