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:

Table 1. QSFP28 and QSFP+ Port Partitioning
Switch model	Port bandwidth	Port partitions
X465 (all models) SFP28	25 Gb	One 10 Gb port
X465 (all models) QSFP+	40 Gb	One 40 Gb port or Four 10 Gb ports
X670-G2-48x-4q QSFP+	40 Gb	One 40 Gb port or Four 10 Gb ports
X590 (all models) QSFP28 and QSFP+	100 Gb	One 100 Gb port with one of the following: Two 50 Gb ports Four 25 Gb ports
X590 (all models) QSFP28 and QSFP+	40 Gb	One 40 Gb port or Four 10 Gb ports
X690 (all models) QSFP28 and QSFP+	100 Gb	One 100 Gb port with one of the following: Two 50 Gb ports Four 25 Gb ports
X690 (all models) QSFP28 and QSFP+	40 Gb	One 40 Gb port or Four 10 Gb ports
X695 (all models) QSFP	100 Gb	One 100 Gb port (default) with one of the following: Two 50 Gb ports One 40 Gb port Four 25 Gb ports Four 10 Gb ports
X870 (all models) QSFP28 and QSFP+	100 Gb	One 100 Gb port with one of the following: Two 50 Gb ports Four 25 Gb ports Note: On X870-96x-8c series switches, an optional Switch Port Speed License is required to increase the data rate to 100 Gb on physical ports 1 through 24. No license is required for 100 Gb capability on physical ports 25 through 32.
X870 (all models) QSFP28 and QSFP+	40 Gb	One 40 Gb port or Four 10 Gb ports
