firmwareKeyShow

Displays the public key used for signed firmware validation.

Synopsis firmwarekeyshow

Description This command displays the contents of the public key used for validating the integrity of firmware images when

signed firmware validation is enabled.

Notes A firmware key should be installed on every switch as a part of the Fabric OS installation. The presence of a

firmware key does not imply that the firmware signature is checked during firmwareDownload. Signed Firmware

Download must be enabled before the public key can be used for signature validation.

Use the configure command to enable Signed Firmware Download.

If Signed Firmware Download is enabled, and if the validation succeeds, firmware download proceeds normally. If

the firmware is not signed or if the signature validation fails, signed firmware download fails.

Refer to the Fabric OS Administrator's Guide for complete details on upgrading or downgrading firmware.

The execution of this command is subject to Virtual Fabric restrictions that may be in place. Refer to "Using Fabric

OS Commands" and "Command Availability" for details.

Operands None
