Port Partitioning

On some ExtremeSwitching Universal 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:

Table 1. Port Partitioning
Switch Model	Port Bandwidth	Port Partitions
5720 (all models) QSFP28 (U1 and U2 ports)	100 Gb	One U1 or U2 port with one of the following: One 100 Gb port (default) Two 50 Gb ports (Switch Engine only) One 40 Gb port Four 25 Gb ports Four 10 Gb ports
5720-VIM-6YE SFP28	25 Gb	The 5720-VIM-6YE has two speed groups, each with three ports that can be partitioned with the following: Three 1 Gb ports Three 10 Gb ports Three 25 Gb ports (default)
5720-VIM-2CE QSFP28	100 Gb	The 5720-VIM-2CE has two ports, each of which can be partitioned with the following: One 100 Gb port (default) One 40 Gb port Four 25 Gb ports Four 10 Gb ports
