Connectivity Guide

speed (Fibre Channel)
Congures the transmission speed of a Fibre Channel interface.
Syntax
speed {8 | 16 | 32 | auto}
Parameters Set the speed of a Fibre Channel interface to:
• 8 — 8GFC
• 16 — 16GFC
• 32 — 32GFC
• auto — Set the port speed to the speed of the installed media.
Defaults Auto
Command Mode INTERFACE
Usage Information
The speed command is supported only on Management and Fibre Channel interfaces. This command is not
supported on Ethernet interfaces.
• To congure oversubscription for bursty storage trac on a FC interface, use the speed command.
Oversubscription allows a port to operate faster, but may result in trac 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
Supported Releases 10.3.1E or later
speed (Management)
Congures the transmission speed of the Management interface.
Syntax
speed {10 | 100 | 1000 | auto}
Parameters Set the Management port speed to:
• 10 — 10M
• 100 — 100M
• 1000 — 1000M
• auto — Set the port to auto-negotiate speed with a connected device.
Defaults Auto
Command Mode INTERFACE
Usage Information
The speed command is supported only on Management and Fibre Channel interfaces. This command is not
supported on Ethernet interfaces.
• When you manually congure the Management port speed, match the speed of the remote device. Dell EMC
highly recommends using auto-negotiation for the Management port.
