On some Extreme Networks 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:
| Switch Model | Port Bandwidth | Port Partitions |
|---|---|---|
| 7720-32C | 100 Gb or 40 Gb | Ports 1-27 and 29-32 with one of the following:
Note: Port 28 cannot be partitioned and is 40/100G capable only.

For information about configuring partitioned ports, see the Switch Engine Command References for your version of the Switch Engine operating system, or the Fabric Engine Command References for your version of the Fabric Engine operating system.
