nv action change system date-time

Configures the Cumulus Linux software clock. The switch contains a battery backed hardware clock that maintains the time while the switch powers off and between reboots. When the switch is running, the Cumulus Linux operating system maintains its own software clock.

During boot up, the switch copies the time from the hardware clock to the operating system software clock. The software clock takes care of all the timekeeping. During system shutdown, the switch copies the software clock back to the battery backed hardware clock.

The date format is YYYY-MM-DD. The time format is HH:MM:SS.

nv action clear system api session user <user-id>

Clears an NVUE user session.

NVUE uses sessions to authenticate and authorize requests. After authenticating the user with the first request, NVUE stores the session in the nvued cache. NVUE authenticates subsequent interactions within the session locally, eliminating the need to repeatedly check with external authentication servers. This process enhances system performance and efficiency, making it ideal for high-traffic environments.

• If you make changes to a user group, password, RADIUS, TACACS, or LDAP server setting locally on the switch, NVUE clears the current session automatically.

• If you make changes directly on the RADIUS, TACACS, or LDAP server, you must clear the user session with the nv action clear system api session user <user> command or clear all sessions with the nv action clear system api session command.

  If you do not clear a user session after making changes directly on the RADIUS, TACACS, or LDAP server, NVUE uses the existing session for authentication and authorization until the session times out (up to 60 minutes).

Command Syntax

Version History

Introduced in Cumulus Linux 5.10.0

Example

cumulus@switch:~$ nv action clear system api session user admin

nv action import system security ca-certificate <cert-id>

Imports a CA certificate.

Cumulus Linux includes a self-signed certificate and private key to use on the server so that it works out of the box. The switch generates the self-signed certificate and private key when it boots for the first time. The X.509 certificate with the public key is in /etc/ssl/certs/cumulus.pem and the corresponding private key is in /etc/ssl/private/cumulus.key.

NVIDIA recommends you use your own certificates and keys.

• You can import a maximum of 50 CA certificates on the switch.
• The CA certificate you import contains sensitive private key information. NVIDIA recommends that you use a secure transport such as SFTP, SCP, or HTTPS.
• If the certificate is passphrase protected, you need to include the passphrase.
• You must provide a certificate ID (<cert-id>) to uniquely identify the certificate you import.

Introduced in Cumulus Linux 5.7.0

Example

cumulus@switch:~$ nv action import system security ca-certificate tls-cert-1 passphrase mypassphrase data "<public-key>" 

nv action import system security certificate <cert-id>

Imports an entity certificate or certificate bundle.

Cumulus Linux includes a self-signed certificate and private key to use on the server so that it works out of the box. The switch generates the self-signed certificate and private key when it boots for the first time. The X.509 certificate with the public key is in /etc/ssl/certs/cumulus.pem and the corresponding private key is in /etc/ssl/private/cumulus.key.

NVIDIA recommends you use your own certificates and keys.

• You can import a maximum of 25 entity certificates on the switch.
• The certificate you import contains sensitive private key information. NVIDIA recommends that you use a secure transport such as SFTP, SCP, or HTTPS.
• If the certificate is passphrase protected, you need to include the passphrase.
• A certificate bundle must be in .PFX or .P12 format.
• You must provide a certificate ID (<cert-id>) to uniquely identify the certificate you import.
