Port Partitioning - Extreme Networks ExtremeSwitching X435 Series Hardware Installation Manual

ExtremeSwitching Switches
connect copper ports x and y on a switch, and then insert SFPs into ports x and y, the switch
assigns the copper ports as active ports and the fiber ports as redundant ports.
Hardware identifies when a link is lost and responds by swapping the primary and redundant ports to
maintain stability. After a failover occurs, the switch keeps the current port assignment until another
failure occurs or a user changes the assignment using the CLI. For more information about configuring
automatic failover on combination ports, see the

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:
