Port Partioning

With port partitioning (or channelization), you can configure a single port to operate as four individual ports. Port partitioning is supported for the following port speeds:
40 Gbps (QSFP+)
When partitioned, the port operates as four seperate 10 Gbps ports while using QSFP+ cables.
100 Gbps (QSFP28)
When partitioned, the port operates as four seperate 25 Gbps ports while using QSFP28 cables.

When partitioning either 40 Gbps QSFP+ ports or 100 Gbps QSFP28 ports, only the eight even numbered ports can be partioned. The lower odd numbered port interface is blocked when the higher even numbered port interface is partioned. You can use 40GBASE-CR4 (copper) or 40GBASE-SR4 (fiber) or 100GBASE-CR4 (copper) or 100GBASE-SR4 (fiber) breakout cables to connect the 40/100 Gigabit Ethernet ports to other servers, storage devices, and switches. For breakout cable details, see Extreme Networks Pluggable Transceivers Installation Guide.

Ports are not partitioned by default. If partitioning is not enabled, the ports display the existing port format as “slot/port”. When partitioning is enabled, ports display the format as “slot/port/sub-port” in the input/output.
