Chapter 4 C Commands crypto key zeroize rsa Send documentation comments to [email protected] crypto key zeroize rsa To delete an RSA key pair from the switch, use the crypto key zeroize rsa command in configuration mode. crypto key zeroize rsa key-pair-label Syntax Description key-pair-label Specifies the RSA key pair to delete. The maximum size is 64 characters. Defaults None. Command Modes Configuration mode. Command History Release 3.0(1) Modification This command was introduced. Usage Guidelines If you believe the RSA key pair on your switch was compromised in some way and should no longer be used, you should delete it. After you delete the RSA key pair on the switch, ask the CA administrator to revoke your switch's certificates at the CA. You must supply the challenge password you created when you originally requested the switch's certificates. Before deleting a key pair, you should delete the identity certificates corresponding to it in various trust points if the identity certificates exist, and then disassociate the key pair from those trust points. The purpose of this is to prevent accidental deletion of a key pair for which there exists an identity certificate in a trust point. Note The trust point configuration, certificates, and key pair configurations are made persistent only after saving to the startup configuration. To be consistent with this configuration behavior, the delete behavior is also the same. That is, the deletions are made persistent only after saving to the startup configuration. Use the copy running-config startup-config command to make the certificate and key pair deletions persistent. Examples The following example shows how to delete an RSA key pair called testkey. switch# config terminal switch(config)# crypto key zeroize rsa testkey OL-16217-01, Cisco MDS SAN-OS Release 3.x Cisco MDS 9000 Family Command Reference 4-137
