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.
Note100G is not supported on the ExtremeSwitching 5520 series switches QSFP28 ports.
NoteWhen 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.
NoteThis 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.
NoteBecause of the nature of these ports at the physical layer level, the 10G side may show a remote or local linkup.
