Smart Licensing

1. In config mode:

 call-home
  vrf management
  service active
  contact smart-licensing
  source-interface MgmtEth0/RP0/CPU0/0
  profile CiscoTAC-1
   active
   destination address http https://tools.cisco.com/its/service/oddce/services/DDCEService
   destination transport-method http
  !
 !
 
 crypto ca trustpoint Trustpool
  vrf management

2. In exec mode:

Our NCS' didn't ship with all the CA's, so we downloaded them:

 crypto ca trustpool import url http://www.cisco.com/security/pki/trs/ios.p7b

3. Check to make sure CA's were installed (should be more than five certs now):

 show crypto ca trustpool

4. Now license the router:

 license smart register idtoken <insert_token_here>

 show license status
