Connectivity Guide

3. Use the security profile to configure X.509v3-based service; for example, to configure RADIUS over TLS authentication
using an X.509v3 certificate, enter the radius-server host tls command:
radius-server host {hostname | ip-address} tls security-profile profile-name
[auth-port port-number] key {0 authentication-key | 9 authentication-key |
authentication-key}
Example: Security profile configuration and use for RADIUS over TLS authentication

Cluster security
When you enable VLT or a fabric automation application, switches that participate in the cluster use secure channels to
communicate with each other. The secure channels are enabled only when you enable the cluster (VLT or fabric) configuration
on a switch. OS10 installs a default X.509v3 certificate-key pair, which is used to establish secure channels between peer
devices in a cluster.
In a deployment where untrusted devices access the management or data ports on an OS10 switch, you should replace
the default certificate-key pair used for cluster applications. Create a custom X.509v3 certificate-key pair by configuring an
application-specific security profile with the cluster security-profile command.
When you replace the default certificate-key pair for cluster applications, ensure that all devices in the cluster use the same
custom certificate-key pair or a unique certificate-key pair issued by the same CA.
CAUTION:
While you replace the default certificate-key pair, cluster devices temporarily lose their secure
channel connectivity. It is, therefore, recommended that you change the cluster security configuration during a
maintenance window.
This example shows how to install an X.509v3 CA and host certificate-key pair for a cluster application. For more information,
see:
● Importing and installing a CA certificate — see Manage CA certificates.
● Generating a CSR and installing a host certificate — see Request and install host certificates.
1. Install a trusted CA certificate.

home:// GeoTrust_Universal_CA.crt
OS10# crypto ca-cert install home://GeoTrust_Universal_CA.crt
