Configure Trustpoints and Install Certificates on MDS 9000 Switches

Introduction

This document describes the configuration steps for the configuration of Trustpoint and Certificates in the MDS switches.

Background Information

Public Key Infrastructure (PKI) support provides the means for the Cisco Multilayer Director Switch (MDS) 9000 Family switches to obtain and use digital certificates for secure communication in the network. PKI support provides manageability and scalability for IP Security (IPsec), Internet Key Exchange (IKE), and Secure Shell (SSH).

Prerequisites

You must configure the host name and IP domain name of the switch if they are not already configured.

switch# configuration terminal
switch(config)# switchname <switchName> 
SwitchName(config)# ip domain-name example.com 

Note: Changing the IP host name or IP domain name after generating the certificate can invalidate the certificate.

Understanding of few related keywords

Trustpoint : A locally configured object that contains informtion about a trusted Certificate Authority (CA), including the local RSA keypair, the CA public certificate(s), and the identity certificate issued to the switch by a CA.  Mutiple trustpoints can be configured to enroll switch identity certificates from multiple CAs.  The complete identity information in a trust point can be exported to a file in the password-protected PKCS12 standard format. It can be later imported to the same switch (for example, after a system crash) or to a replacement switch. The information in a PKCS12 file consists of the RSA key-pair, the identity certificate, and the CA certificate (or chain). 

CA Certificate : This is the certificate that is issued by the Certification Authority (CA) in respect to itself. There could be an Intermeidate or Subordinate CA in the setup.  In that case, this could also refer to the Intermediate or Subordinate CA public certificate.

Certificate Authorities (CAs) : Devices that manage certificate requests and issue identity certificates to entities such as hosts, network devices, or users. CAs provide centralized key management for such entities.

RSA keypair : Generated with cli in the switch and associated with the the trustpoint.  For each trustpoint configured on the switch, you must generate a unique RSA keypair and associate it with the trustpoint. 

Certification Signing request (CSR) This is request that is generated from the switch and sent to CA to be signed. Against this CSR the CA sends back the Identity Certificate.

Identity Certificate : This is the certificate that is signed and issued by the Certification Authority for the switch from which the CSR is generated.  Once a CSR is submitted to a CA, the CA or an administrator provides the Identity Certificate by e-mail or through a web browser.  In order to paste an Identity Certificate into an MDS trustpoint, it must be in standard PEM (base64) format.

Requirements

Root CA .

Sub CA Certificates (If the Identity Certificates are signed by the Sub CA) In this case CA certificates of Sub CA are also required to be added in the switch.

Identity Certificate

Configure

Step 1

Generate an RSA key-pair

switchName# configure terminal 
switchName(config)# crypto key generate rsa label <rsaKeyPairName> exportable modulus xxx  

(Valid modulus values are (default) 512, 768, 1024, 1536, 2048, and 4096)

Step 2

Create a CA Trust Point and Associate the RSA keypair with the Trustpoint

The switch FQDN is used as a default key label when none is specified during key-pair generation.

switchName(config)# crypto ca trustpoint <trustpointName>
switchName(config-trustpoint)# enroll terminal 
switchName(config-trustpoint)# rsakeypair <rsaKeyPairName>

Step 3

Authenticating a Trust Point Certificate Authority

If the CA being authenticated is not a self-signed CA, then the full list of the CA certificates of all the CAs in the certification chain needs to be input during the CA authentication step. This is called the CA certificate chain of the CA being authenticated. The maximum number of certificates in a CA certificate chain is 10.

When Only there is Root CA

switchName# configure terminal

switchName(config)# crypto ca authenticate <trustpointName> 

input (cut & paste) CA certificate (chain) in PEM format;
end the input with a line containing only END OF INPUT :

Blue color Text -> This is copied from the CA certificate (open in any text editor) and pasted when prompted in the switch CLI.

Red Color Text -> This is to be entered to end the certifcate.

Any Error in in the the certificate results in this

failed to load or parse certificate
could not perform CA authentication

If you try to authenticate from a Sub CA certificate without adding the Root CA certificate you get

incomplete chain (no selfsigned or intermediate cert)
could not perform CA authentication

If everything is good

Create the certificate request..
Create a challenge password. You  need to verbally provide this

For security reasons your password not be saved in the configuration.
Please make a note of it.

Include the switch serial number in the subject name? [yes/no]: no

-----END CERTIFICATE REQUEST-----

The challenge password is not saved with the configuration. This password is required in the event that your certificate needs to be revoked, so you must remember this password.

Note: Do not use the '$' character for your password.  It causes the CSR to fail.

Copy this starting from

-----BEGIN CERTIFICATE REQUEST-----

Untill

-----END CERTIFICATE REQUEST-----

Save this outside the switch. This needs to be forwarded to the Root CA or Sub CA (whichever one signs) via email or another method.  The CA returns a signed Identity Certificate.

NX-OS 8.4(1) and later.

As a fix for Cisco bug ID CSCvo43832 , the enrollment prompts were changed in NX-OS 8.4(1).

By default, the Subject Name is the same as the switch name.

The enrollment prompts also allow an Alternate Subject Name and multiple DN fields.

Note: The DN field prompts with numbers as examples can accept any string with that range of characters.  For example, the State DN prompt says:

Enter State[1-128]:

It takes any string from 1 to 128 characters.

switchName# configure terminal
switchName(config)# crypto ca enroll <trustpointName>
Create the certificate request ..
Create a challenge password. You need to verbally provide this
password to the CA Administrator in order to revoke your certificate.
