automatic failover on combination ports, see the ExtremeXOS 22.6 User Guide.
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:

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.
