SPDM Commands

nv show system security spdm

	nv show system security spdm Show list of component integrity ERoT in the BMC, with their measurements if present and certificate-chains.
Syntax Description	N/A
Default	N/A
History	25.02.1884
Example	Copy Copied! `admin@nvos:~$ nv show system security spdm Component Id HashingAlgorithm --------------- --------- ---------------- ERoT_BMC_0 CertChain None ERoT_CPU_0 CertChain None ERoT_FPGA_0 CertChain None ERoT_NVSwitch_0 CertChain None ERoT_NVSwitch_1 CertChain None` Copy Copied! `admin@nvos:~$ nv show system security spdm ERoT_BMC_0 operational ------------------ ----------- measurements HashingAlgorithm None certificates Id CertChain`
REST API	GET https://<ip>/nvue_v1/system/security/spdm
Related Commands	nv action generate system security spdm nv show system security spdm measurements nv show system security spdm certificates
Notes	The output differs between JSON and regular "nv show" formats. The regular display will only show a list of ERoT and only if the relevant fields are present. In contrast, the JSON output is much longer, comprising five ERoT responses. In th output, when the name of the component is listed, the possible outcomes are as follows: (enum:ERoT_BMC_0, ERoT_CPU_0, ERoT_FPGA_0, ERoT_NVSwitch_0, ERoT_NVSwitch_1)

nv show system security spdm certificates

	nv show system security spdm certificates Shows certificate-chain of component integrity ERoT in the BMC.
Syntax Description	N/A
Default	N/A
History	25.02.1884
Example	Copy Copied! `admin@nvos:~$ nv show system security spdm ERoT_BMC_0 certificates operational -- ----------- Id CertChain nv show sys sec spdm ERoT_CPU_0 certificates -ojson { "CertificateString": "-----BEGIN CERTIFICATE-----\n…AX\n-----END CERTIFICATE-----\n", "CertificateType": "PEMchain", "CertificateUsageTypes": [ "Device" ], "Id": "CertChain", "Name": "MGX_ERoT_CPU_0 Certificate Chain", "SPDM": { "SlotId": 0 } }`
REST API	GET https://<ip>/nvue_v1/system/security/spdm/ERoT_BMC_0/ certificates
Related Commands	nv action generate system security spdm nv show system security spdm measurements nv show system security spdm
Notes	The output differs between JSON and regular "nv show" formats. The regular display will only show a list of ERoT and only if the relevant fields are present.

nv show system security spdm measurements

	nv show system security spdm measurements Shows certificate-chain of component integrity ERoT in the BMC.
Syntax Description	N/A
Default	N/A
History	25.02.1884
Example	Copy Copied! `admin@nvos:~$ nv show system security spdm ERoT_BMC_0 certificates operational ------------------ ----------- measurements HashingAlgorithm None nv show sys sec spdm ERoT_CPU_0 measurements -ojson { "HashingAlgorithm": "None", "SignedMeasurements": "", "SigningAlgorithm": "None", "Version": "unknown" }`
REST API	GET https://<ip>/nvue_v1/system/security/spdm/ERoT_BMC_0/ measurements
Related Commands	nv action generate system security spdm nv show system security spdm certificates nv show system security spdm
Notes	Result differs on Json and nv show format – regular show will show only list of ERoT and if fields are present

nv action generate system security spdm

	nv action generate system security spdm Generate measurements on BMC.
Syntax Description	nonce	64 char hex string
