Partitioning High Bandwidth Ports

The ExtremeSwitching 5520 switch QSFP28 ports in Ethernet mode can be configured for 40G (default), 2x50G, 4x25G or 4x10G. These ports are normally configured for stacking. To use these for Ethernet, you must disable stacking support.

Note

100G is not supported on the ExtremeSwitching 5520 series switches QSFP28 ports.

Note

When replacing a Universal switch (for example, the ExtremeSwitching 5420 series or ExtremeSwitching 5520 series switch) that is not in a stack, stacking-support should be disabled before applying a configuration where port partitioning is enabled on either of the Universal ports (U1 or U2).

Additionally, on ExtremeSwitching 5520 (with 5520-VIM-4YE) switches, the 25G ports can be partitioned into 10G.

Note

This partition allows all ports to be converted either as 10G or as 25G and not both. To partition the 25G ports, apply the 4x10 option in the following command to the first VIM port (port 33 for 24-port models and port 57 for 48-port models).

To partition the ports, enter the following command:

configure ports [port_list | all] partition [1x100G | 1x40G | 2x50G | 4x10G | 4x25G]

Additionally, on ExtremeSwitching 5720 switches with 5720-VIM-6YE, the VIM ports can be partitioned to 3x1G, 3x10G or 3x25G. With 5720-VIM-2CE, the VIM ports can be partitioned to 4x10G, 4x25G, 1x40G or 1x100G.

Version 32.5 adds support for ports with different max speed capabilities to be part of the same Link Aggregation Group (LAG). This lets you change the speed and the auto-negotiation configuration of a port that is part of a LAG without unconfiguring and reconfiguring the LAG. This feature also supports dynamic repartitioning of the LAG ports without deleting and then recreating the LAG.
