Configuring the Host Name and IP Domain Name

You must configure the host name and IP domain name of the switch if they are not already configured.
This is required because switch FQDN is used as the subject in the identity certificate. Also, the switch
FQDN is used as a default key label when none is specified during key-pair generation. For example, a
certificate named SwitchA.example.com is based on a switch host name of SwitchA and a switch IP
domain name of example.com.
Caution Changing the host name or IP domain name after generating the certificate can invalidate the certificate.
To configure the host name and IP domain name, refer to the Cisco MDS 9000 NX-OS CLI Configuration
Guide.

Generating an RSA Key-Pair

RSA key-pairs are used to sign and/or encrypt and decrypt the security payload during security protocol
exchanges for applications such as IKE/IPsec and SSH, and they are required before you can obtain a
certificate for your switch.
To generate an RSA key-pair using Fabric Manager, follow these steps:
Expand Switches > Security and then select PKI in the Information pane.
Step 1
Click the RSA Key-Pair tab.
Step 2
