TitleHow to configure different port speeds on the X870
Objective
Configure the ports on the X870 to run at the different speeds.
Environment
X870-32c
X870-96x-8c
Procedure
There are two different models of the X870. The first step is to determine which model you have.

1. The X870-32c has 32 unrestricted QSFP28 ports available that can be configured to the following speeds:
  • up to 32x100Gb
  • up to 32x40Gb
  • up to 64x50Gb
  • up to 128x25Gb
  • up to 128x10Gb
2. The X870-96x-8c has 96 10Gb ports on 24 QSFP28 ports that are restricted to 10Gb. It also has 8 unrestricted QSFP28 ports that can be configured to the following speeds:
  • up to 8x100Gb
  • up to 8x40G
  • up to 16x50Gb
  • up to 32x25Gb
  • up to 32x10Gb
For restricted ports, the speed is limited to 10Gb. Each restricted QSFP28 port can be used as 4x10Gb ports.

For unrestricted ports, the default speed is 100Gb. To change the speed you must partition the QSFP28 port:
configure port <port number> partition <partition speed>
 
Each unrestricted QSFP28 port can be partitioned to the following speeds:
  • 1x100G
  • 1x40G
  • 2x50G
  • 4x25G
  • 4x10G
Lastly, you must configure the speed of the partitioned port:
configure port <port number> auto off speed <speed> duplex <duplex>
 
 
Additional notes
If more higher speed ports are needed on the X870-96x-8c, then a license can be purchased to add 25Gb/40Gb/50Gb/100Gb capability to groups of 6 QSFP28 restricted ports. Up to four licenses can be applied per switch.
