NUM Status Description Q Ports
1 down
Supported Releases 10.2.0E or later
shutdown
Disables an interface.
Syntax
shutdown
Parameters None
Default Disabled
Command Mode INTERFACE
Usage Information
This command marks a physical interface as unavailable for trac. Disabling a VLAN or a port-channel causes
dierent behavior. When you disable a VLAN, the L3 functions within that VLAN are disabled, and L2 trac
continues to ow. Use the shutdown command on a port-channel to disable all trac on the port-channel, and
the individual interfaces. Use the no shutdown command to enable a port-channel on the interface. The
shutdown and description commands are the only commands that you can congure on an interface that is
a port-channel member.
Example
OS10(config)# interface ethernet 1/1/7
OS10(conf-if-eth1/1/7)# no shutdown
Supported Releases 10.2.0E or later
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.
