Usage Information

The speed command is supported only on the Management and Fibre Channel interfaces. This command is not supported on Ethernet interfaces.

  • To configure oversubscription for bursty storage traffic on a FC interface, use the speed command. Oversubscription allows a port to operate faster, but may result in traffic loss. For example, QSFP28 port groups in 4x8GFC mode support 16GFC oversubscription on member interfaces. QSFP28 breakout interfaces in 4x16GFC mode support 32GFC oversubscription.
  • The no version of this command resets the port speed to the default value auto.
Example
OS10(conf-if-fc-1/1/2)# speed 16
