Want to summarize with AI?

Details the configuration, provisioning, management, and verification of locally significant certificates (LSCs), including RSA key and PKI trustpoint setup, certificate enrollment, AP LSC provisioning, trustpool management, and secure wireless network authentication using both GUI and CLI procedures.

Configure RSA key for PKI trustpoint

Generate RSA cryptographic keys for PKI trustpoint authentication and secure communications.

RSA keys are essential components of PKI infrastructure, providing the cryptographic foundation for certificate-based authentication and encryption on wireless controllers.

Before you begin

Ensure the device is in a stable operational state and has sufficient processing resources for key generation.

Procedure

Enter global configuration mode.
Example:
```
Device# configure terminal
```
Generate RSA key for PKI trustpoint.
Example:
```
Device(config)# crypto key generate rsa exportable general-keys modulus key-size label RSA-key-label
```
Example:
```
Device(config)# crypto key generate rsa exportable 
general-keys modulus 2048 label lsc-tp
```
exportable is an optional keyword. You may or may not want to configure an exportable-key. If selected, you can export the key out of the box, if required.
- key-size: Size of the key modulus. The valid range is from 2048 to 4096.
- RSA-key-label: RSA key pair label.
Return to privileged EXEC mode.
Example:
```
Device(config)# end
```

The RSA key is successfully generated and labeled for use with PKI trustpoint configurations.

Configure PKI trustpoint parameters

Configure a PKI trustpoint with RSA key parameters for certificate enrollment and authentication.

PKI trustpoints define the relationship between the device and a Certificate Authority (CA), enabling secure certificate-based authentication and encryption.

Before you begin

Ensure the CA server is accessible and configured to accept certificate requests.

Procedure

Enter global configuration mode.
Example:
```
Device# configure terminal
```
Create a new trustpoint for an external CA server.
Example:
```
Device(config)# crypto pki trustpoint trustpoint-name
```
Example:
```
Device(config)# crypto pki trustpoint microsoft-ca
```
The trustpoint-name refers to the trustpoint name.
Specify the URL of the CA on which your router should send certificate requests.
Example:
```
Device(ca-trustpoint)# enrollment url HTTP-URL
```
Example:
```
Device(ca-trustpoint)# enrollment url http://CA_server/certsrv/mscep/mscep.dll
```
HTTP-URL: URL of the file system where your router should send certificate requests. An IPv6 address can be added in the URL enclosed in brackets. For example: http://[2001:DB8:1:1::1]:80. For more enrollment method options, see the enrollment url (ca-trustpoint) command page.

Create subject name parameters for the trustpoint.

Example:

Device(ca-trustpoint)# subject-name subject-name

Example:

Device(ca-trustpoint)# subject-name C=IN, ST=KA, L=Bengaluru, O=Cisco, CN=eagle-eye/emailAddress=support@abc.com

Map RSA key with that of the trustpoint.
Example:
```
Device(ca-trustpoint)# rsakeypair RSA-key key-size
```
Example:
```
Device(ca-trustpoint)# rsakeypair ewlc-tp1
```
- RSA-key: RSA key pair label.
- key-size: Signature key length. Range is from 360 to 4096.

Configure revocation checking method.

Example:

Device(ca-trustpoint)# revocation {crl | none | ocsp}

Example:

Device(ca-trustpoint)# revocation none

Return to privileged EXEC mode.
Example:
```
Device(ca-trustpoint)# end
```

The PKI trustpoint is now configured with the specified parameters and ready for certificate enrollment operations.

Authenticate and enroll a Public Key Infrastructure (PKI) trustpoint (GUI)

Authenticate and enroll the PKI trustpoint with CA server (CLI)

Establish secure communication between the device and Certificate Authority by authenticating and enrolling a PKI trustpoint.

PKI trustpoints enable secure certificate-based authentication. The authentication process fetches the CA certificate, while enrollment generates and submits a certificate request to obtain a client certificate.

Before you begin

Ensure the PKI trustpoint is configured and the CA server is accessible.

Procedure

Enter global configuration mode.
Example:
```
Device# configure terminal
```

Fetch the CA certificate.

Example:

Device(config)# crypto pki authenticate trustpoint-name

Example:

Device(config)# crypto pki authenticate microsoft-ca

Accept the CA certificate.

Example:

Device(config)# % Do you accept this certificate? [yes/no]: 
yes Trustpoint CA certificate accepted.

Enroll the client certificate.

Example:

Device(config)# crypto pki enroll trustpoint-name

Example:

Device(config)# crypto pki enroll microsoft-ca
%
% Start certificate enrollment .. 
% Create a challenge password. You will need to verbally 
provide this password to the CA Administrator in order to 
revoke your certificate. For security reasons your password 
will not be saved in the configuration.
Please make a note of it.

Enter a challenge password to the CA server.
Example:
```
Device(config)# password
```
Example:
```
Device(config)# abcd123
```
Re-enter the challenge password to the CA server.
Example:
```
Device(config)# password
```
Example:
```
Device(config)# abcd123
```

Include the router serial number in the subject name.

Example:

Device(config)# % Include the router serial number
in the subject name? [yes/no]: yes

Exclude IP address from the subject name.

Example:

Device(config)# % Include an IP address 
in the subject name? [no]: no

Request certificate from CA.

Example:

Device(config)# 
Request certificate from CA? [yes/no]: yes
% Certificate request sent to Certificate Authority
% The 'show crypto pki certificate verbose
client' command will show the fingerprint.

Return to privileged EXEC mode.
Example:
```
Device(config)# end
```

The PKI trustpoint is authenticated and enrolled with the CA server, enabling secure certificate-based communication.

Import a CA certificate to the trustpool (GUI)

PKI Trustpool Management is used to store a list of trusted certificates (either downloaded or built in) used by the different services on the controller. This is also used to authenticate a multilevel CA certificate. The built in CA certificate bundle in the PKI trustpool receives automatic updates from Cisco if they are not current, are corrupt, or if certain certificates need to be updated.

Perform this task to manually update the CA certificates in the PKI trustpool.

Note

If your LSC has been issued by an intermediate CA, you must import the complete chain of CA certificates into the trustpool. Otherwise, you will not be able to provision the APs without the complete chain being present on the controller. The import step is not required if the certificate has been issued by a root CA.

Follow these steps to import a CA certificate to the trustpool using GUI:

Procedure

Choose Configuration > Security > PKI Management.
In the PKI Management window, click the Trustpool tab.
Click Import.
In the CA Certificate field, copy and paste the CA certificate. Link together the multiple CA certificates in .pem format.
Click Apply to Device.
