Here's a Cisco link and a video tutorial to configure Cisco Smart Licensing Using Policy (CSLU). Below are the commands to be used in a Cisco IOS-XE device.
In the Cisco Smart Software Manager (CSSM, a.ka. Smart License), click the blue hyperlink > CLSU Transport URL.
ip name-server <PRIMARY DNS IP> <SECONDARY DNS IP>
ip domain lookup
ip domain lookup source-interface Loopback0
ip http client source-interface Loopback0
license smart transport cslu
license smart url cslu https://<ON PREM SMART LICENSE SERVER IP>/cslu/v1/pi/<VIRTUAL ACCOUNT>
crypto pki trustpoint SLA-TrustPoint
revocation-check none
#license smart sync all
I've configured CLSU in a Cisco 8000v router
C8000v#conf t
Enter configuration commands, one per line. End with CNTL/Z.
C8000v(config)#ip name-server 10.6.6.7 10.8.8.9
C8000v(config)#ip domain lookup
C8000v(config)#ip domain lookup source-interface Loopback0
C8000v(config)#ip http client
C8000v(config)#license smart transport cslu
C8000v(config)#license smart url cslu https://myccsm01.com/cslu/v1/pi/my-va-4
C8000v(config)#crypto pki trustpoint SLA-TrustPoint
C8000v(ca-trustpoint)# revocation-check none
C8000v(ca-trustpoint)#end
C8000v#write memory
