5.2(1)	This command was introduced.

Usage Guidelines

In Cisco NX-OS releases prior to 5.2(1), you must use the setup utility to change or reapply the default CoPP policy. You can access the setup utility using the setup command.

Beginning with Cisco NX-OS Release 5.2, the CoPP best practice policy is read-only. If you want to modify its configuration, you must clone it using the copp clone profile command. Cloned policies are treated as user configurations.

When you use in-service software downgrade (ISSU) to upgrade to Cisco NX-OS Release 5.2, the policy attached to the control plane is treated as a user-configured policy. Check the CoPP profile using the show copp profile command and make any required changes.

If you use ISSU to downgrade from Cisco NX-OS Release 5.2, CoPP reports the incompatible configuration and instructs you to clone the CoPP profile. In the lower version, all configurations are restored in user-configuration mode.

This command does not require a license.

Examples

This example shows how to apply the default CoPP best practice policy on the Cisco NX-OS device:

Defaults

None

Command Modes

Global configuration

Supported User Roles

network-admin
vdc-admin

Command History

Release	Modification
4.1(2)	This command was introduced.

Usage Guidelines

You can use this command to authenticate the CA to the Cisco NX-OS device by obtaining the self-signed certificate of the CA that contains the public key of the CA. Because the CA signs its own certificate, you should manually authenticate the public key of the CA by contacting the CA administrator when you execute this command. The CA certificate or certificate chain must be available in Privacy Enhanced Mail (PEM) (base-64) encoded format.

Use this command when you initially configure certificate authority support for the device. First create the trustpoint using the crypto ca trustpoint command using the CA certificate fingerprint published by the CA. You must compare the certificate fingerprint displayed during authentication with the one published by the CA and accept the CA certificate only if it matches.

If the CA to authenticate is a subordinate CA (it is not self-signed), then another CA certifies it, which in turn may be certified by yet another CA, and so on, until there is a self-signed CA. In this case, the subordinate CA has a CA certificate chain. You must enter the entire chain during CA authentication. The maximum length that the CA certificate chain supports is ten.

The trustpoint CA is the certificate authority that you configure on the device as the trusted CA. The device accepts any peer certificate if it is signed by a locally trusted CA or its subordinates.

---

Note The trustpoint configuration that you create with the crypto ca trustpoint command persists across device reboots only if you save it explicitly using the copy running-config startup-config command. The certificates and CRL associated to a trustpoint are automatically persistent when you save the trustpoint configuration in the startup configuration. Otherwise, if you do not saved the trustpoint in the startup configuration, the associated certificates and CRL are not automatically persistent because they cannot exist without the corresponding trustpoint after the device reboots.

To ensure that the configured certificates, CRLs, and key pairs are persistent, always save the running configuration in the startup configuration.

---

This command does not require a license.

Examples

This example shows how to authenticate a CA certificate called admin-ca:

switch# configure terminal

switch(config)# crypto ca authenticate myCA

input (cut & paste) CA certificate (chain) in PEM format;

4.1(2)	This command was introduced.

Usage Guidelines

A Cisco NX-OS device enrolls with the trustpoint CA to obtain an identity certificate. You can enroll your device with multiple trustpoints and obtain a separate identity certificate from each trustpoint.

When enrolling with a trustpoint, you must specify an RSA key pair to certify. You must generate the key pair and associate it to the trustpoint before generating the enrollment request.

Use the crypto ca enroll command to generate a request to obtain an identity certificate from each of your trustpoints that correspond to authenticated CAs. The certificate signing request (CSR) generated is per the Public-Key Cryptography Standards (PKCS) #10 standard and is displayed in the PEM format. You then cut and paste the certificate and submit it to the corresponding CA through an e-mail or on the CA website. The CA administrator issues the certificate and makes it available to you either through the website or by sending it in an e-mail. You need to import the obtained identity certificate that corresponds to the trustpoint using the crypto ca import trustpoint-label certificate command.

---

Note The device does not save the challenge password with the configuration. Record this password so that you can provide it if you need to revoke your certificate.

---

This command does not require a license.

Examples

This example shows how to generate a certificate request for an authenticated CA:

switch# configure terminal

switch(config)# crypto ca enroll myCA

 Create the certificate request ..

 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.

4.1(2)	This command was introduced.

Usage Guidelines

Trustpoints have the following characteristics:

•A trustpoint corresponds to a single CA, which a Cisco NX-OS device trusts for peer certificate verification for any application.

•A CA must be explicitly associated to a trustpoint using the crypto ca authenticate command.

•A Cisco NX-OS device can have many trustpoints and all applications on the device can trust a peer certificate issued by any of the trustpoint CAs.

•A trustpoint is not restricted to a specific application.

•The Cisco NX-OS device can optionally enroll with a trustpoint CA to get an indemnity certificate for itself.

You do not need to designate one or more trustpoints to an application. Any application should be able to use any certificate issued by any trustpoint as long as the certificate satisfies the application requirement.

You do not need more than one identity certificate from a trustpoint or more than one key pair associated to a trustpoint. A CA certifies a given identity (name) only once and does not issue multiple certificates with the same subject name. If you need more than one identity certificate for a CA, define another trustpoint for the same CA, associate another key pair to it, and have it certified if the CA allows multiple certificates with the same subject name.

---

Note Before using the no crypto ca trustpoint command to remove the trustpoint, you must first delete the identity certificate and CA certificate (or certificate chain) and then disassociate the RSA key pair from the trustpoint. The device enforces this sequence of actions to prevent the accidental removal of the trustpoint with the certificates.

---

This command does not require a license.

Examples

This example shows how to declare a trustpoint CA that the device should trust and enter trustpoint configuration mode:

switch# configure terminal 

switch(config)# crypto ca trustpoint admin-ca

Command History

Release	Modification
4.1(2)	This command was introduced.

Usage Guidelines

This command deletes the CA certificate or certificate chain corresponding to the trustpoint CA. As a result, the trustpoint CA is no longer trusted. If there is an identity certificate form the CA, you must delete it before you can delete the CA certificate. This prevents the accidental deletion of a CA certificate when you have not yet deleted the identity certificate obtained from that CA. Deleting the CA certificate may be necessary when you no longer want to trust the CA because the CA is compromised or the CA certificate has expired.

---

Note The trustpoint configuration, certificates, and key pair configurations are persistent only after saving to the startup configuration. Deletions become persistent only after you save the running configuration to the startup configuration.

Enter the copy running-config startup-config command to make the certificate and key pair deletions persistent.

---

Note Setting the SXP retry period to 0 seconds disables the timer and retries are not attempted.

This command requires the Advanced Services license.
