The commands in this chapter apply to the Cisco MDS 9000 Family of multilayer directors and fabric switches. All commands are shown here in alphabetical order regardless of command mode. See “About the CLI Command Modes” section to determine the appropriate mode for each command.
hardware ejector enable
To enable the hardware card ejector functionality when the ejector lever is unlocked, use the hardware ejector enable command.
Syntax Description

Usage Guidelines
This command does not require a license.
The purpose of the ejector release button on the supervisor or linecard is to unlock the ejector release lever. When enabled, this command causes the supervisor to power down when the ejector release button is pressed. In the case of a linecard, both ejector release buttons have to be pressed in order for the power down of the linecard to occur.
Examples
This example shows the configuration command to enable the hardware power down feature when the ejector release button(s) are pressed:
This example shows the configuration command to disable the hardware power down feature when the ejector release button is pressed:
hardware fabric crc
To enable internal CRC detection and isolation functionality, use the hardware fabric crc command in configuration mode. To disable this functionality, use the no form of the command.
hardware fabric crc [threshold threshold-count]
Syntax Description
Specifies the threshold count, taken over a 24-hour period, consecutively. The range is 1 to 100. |

The following example shows how to disable internal CRC detection and isolation:
hash
Specifies the vsan ID where this flow is accelerated. The range is from 1 to 4093. |
|
To configure a hash algorithm for an IKE protocol policy, use the hash command in IKE policy configuration submode. To revert to the default, use the no form of the command.
Syntax Description
Specifies the MD51 hash algorithm. |
|
Specifies the SHA2. |
|
Defaults
Command Modes
IKE policy configuration submode.
Command History
|
|
Usage Guidelines
To use this command, the IKE protocol must be enabled using the crypto ike enable command.
Examples
The following example shows how to configure the hash algorithm for the IKE protocol:

host
To configure the host PWWN for the flow, use the host command. To delete a flow from a given flowgroup, use the no form of the command.
host {pwwn target pwwn vsan vsan id [tape] [compression]}
no host {pwwn target pwwn vsan vsan id [tape] [compression]}
Syntax Description
Specifies the vsan ID where this flow is accelerated. The range is from 1 to 4093. |

host
Use the host command to configure the switch offline state, the mainframe access control parameters, and the mainframe time stamp parameters. To disable the configuration or to revert to factory defaults, use the no form of the command.
host { control [ switch offline] | port control | set-timestamp }
no host { control [ switch offline] | port control | set-timestamp }
Syntax Description
(Optional) Allows the host to move the switch to an offline state and shut down the ports (default). |

Usage Guidelines
By default, the clock in each VSAN is the same as the switch hardware clock. Mainframe users are allowed to change the VSAN-clock.
Examples
The following example prohibits mainframe users from moving the switch to an offline state:
The following example allows the host to move the switch to an offline state and shut down the ports:
The following example prohibits mainframe users to configure FICON parameters in the Cisco MDS switch (default):
The following example allows mainframe users to configure FICON parameters in the Cisco MDS switch:
The following example prohibits mainframe users from changing the VSAN-specific clock:
The following example allows the host to set the clock on this switch (default):

hw-module logging onboard
To configure on-board failure logging (OBFL), use the hw-module logging onboard command. To disable this feature, use the no form of the command.
hw-module logging onboard [ module slot ] [ log-type ]
no hw-module logging onboard [ module slot ] [ log-type ]
Syntax Description
Defaults

Usage Guidelines
OBFL data uses the module’s persistent logging facility to store data in its CompactFlash memory. When OBFL is disabled, the persistent logging facility discards all entries sent to it for logging.
Examples
The following example configures on-board failure logging of memory leak events on module 2:
