download ssl certificate

download ssl ipaddress certificate {ssl-cert | trusted-ca | ocsp-signature-ca | {csr-cert {ocsp [on | off]}} file_name

Description

Permits downloading of certificate file(s) from files stored on a TFTP server.

Syntax Description


`ipaddress`	Specifies the IP address of the TFTP server.
ssl-cert	Specifies SSL/TLS certificate (default).
trusted-ca	Specifies CA certificates.
ocsp-signature-ca	Specifies signature CA files.
`file_name`	Specifies the name of the certificate file.
csr-cert	Specifies an SSL/TLS certificate signed through a Certificate Signing Request (CSR) generated by the switch. Trust chain verification is performed during download.
ocsp	Specifies using or not using Online Certificate Status Protocol (OCSP) for certificate checking.
on	Enables OCSP for SSL/TLS certificate signed through CSR generated by switch.
off	Disables OCSP for SSL/TLS certificate signed through CSR generated by switch (off).

Default

If no option is selected, SSL/TLS certificate (ssl-cert) is the default.

By default, OCSP is disabled.

Usage Guidelines

If the download operation is successful, any existing certificate is overwritten. For SSL/TLS certificates, after a successful download, the software attempts to match the public key in the certificate against the private key stored. If the private and public keys do not match, the switch displays a warning message similar to the following: Warning: The Private Key does not match with the Public Key in the certificate. This warning acts as a reminder to also download the private key.

Note

You can only download a certificate key in the VR-Mgmt virtual router.

Downloaded certificates and keys are not saved across switch reboots unless you save your current switch configuration. After you issue the save command, the downloaded certificate is stored in the configuration file and the private key is stored in the EEPROM.

You can purchase and obtain SSL certificates from Internet security vendors.
