Default SSL Configuration
The standard HTTP server is enabled.
SSL is enabled.
No CA trustpoints are configured.
No self-signed certificates are generated.
SSL Configuration Guidelines
When SSL is used in a switch cluster, the SSL session terminates at the cluster commander. Cluster
member switches must run standard HTTP.
Before you configure a CA trustpoint, you should ensure that the system clock is set. If the clock is not
set, the certificate is rejected due to an incorrect date.
In a switch stack, the SSL session terminates at the stack master.
Configuring a CA Trustpoint
For secure HTTP connections, we recommend that you configure an official CA trustpoint.
A CA trustpoint is more secure than a self-signed certificate.
Beginning in privileged EXEC mode, follow these steps to configure a CA trustpoint:
Command Purpose
Step 1 configure terminal Enter global configuration mode.
Step 2
hostname hostname Specify the hostname of the switch (required only if you have not
previously configured a hostname). The hostname is required for security
keys and certificates.
Step 3
ip domain-name domain-name Specify the IP domain name of the switch (required only if you have not
previously configured an IP domain name). The domain name is required
for security keys and certificates.
Step 4 crypto key generate rsa (Optional) Generate an RSA key pair. RSA key pairs are required before
you can obtain a certificate for the switch. RSA key pairs are generated
automatically. You can use this command to regenerate the keys, if
needed.
Step 5 crypto ca trustpoint name Specify a local configuration name for the CA trustpoint and enter CA
trustpoint configuration mode.
Step 6
enrollment url url Specify the URL to which the switch should send certificate requests.
Step 7
enrollment http-proxy host-name
port-number
(Optional) Configure the switch to obtain certificates from the CA
through an HTTP proxy server.
Step 8 crl query url Configure the switch to request a certificate revocation list (CRL) to
ensure that the certificate of the peer has not been revoked.
