Cisco CCNA (640-553) Security Training - Using The "Certificate" Command

In at present's article, I'm going to chop-chop inform you in regards to the Cisco IOS certificates chain configuration mode command named "certificate".     

Network directors (such as you) use the "certificate" command to manually add or delete certificates.    

Below is the command syntax:    

certificates certificate-serial-number     

As you possibly can see, the command may be very simple to implement; the certificate-serial-number argument, is the serial variety of the certificates that's to be both added or deleted.    

In the examples beneath, the certificates with the serial variety of "0123456789ABCDEF0123456789ABCDEF" is being added; then deleted. (Example #1 is including and Example #2 is deleting)   

Example #1

Router>allow  

Router#configure terminal  

Router(config)#crypto ca certificates chain ittechtipsca  

Router(config-cert-chain)#certificates 0123456789ABCDEF0123456789ABCDEF  

Router(config-cert-chain)#finish  

Router#copy run begin 

Example #2

Router>allow  

Router#configure terminal  

Router(config)#crypto ca certificates chain ittechtipsca  

Router(config-cert-chain)#no certificates 0123456789ABCDEF0123456789ABCDEF  

% Are you certain you wish to take away the certificates [yes/no]? sure  

% Be certain to ask the CA administrator to revoke this certificates.  

Router(config-cert-chain)#finish  

Router#copy run begin     

As you possibly can see, the way in which to delete a certificates is to kind the phrase "no" in entrance of the command.    

And, in case you determine to make use of the command, ensure your router(s) is in operation Cisco IOS 11.three T or larger.
