Nexus 9000 Smart Licensing Configuration

In this short post, I’ll give you the configuration script I put together to configure Smart Licensing on a Cisco Nexus 9000 switch.

Nexus Smart Licensing Configuration Script

In the following configuration script, I provide the CLI commands I use to configure Smart Licensing on a Nexus 9000 switch using its out-of-band (OOB) management interface that’s under the default VRF management.

To avoid any issues when registering your Nexus switch, make sure that name servers are reachable over the management VRF before entering the token.

config terminal

ip domain-lookup

interface mgmt0
 ip address <mgmt_IP_address>/<mask_bits>
 no shut
 exit

vrf context management
 ip route 0.0.0.0/0 <default_route_next_hop>
 ip domain-name <customer_domain.local>
 ip name-server <your_DNS_server>
 exit

license smart vrf management <<<< this is the default - showing the command for you to be aware
license smart transport smart
exit

license smart trust idtoken <token> all <<<< "all" for all Supervisors

If you have two supervisor cards, the token you create should allow two uses. See next section below on creating a Smart License token.

These are show commands that you can use to verify the configuration.

show license status
show license summary
show license all
show license tech support
show license udi
show license usage

When you display the default configuration for license smart, you’ll see that the default transport is cslu and that needs to change to smart. Also, notice the vrf management is the default.

nexus-switch#  show runn all | inc "license smart"
license smart transport cslu
license smart url smart https://smartreceiver.cisco.com/licservice/license
license smart url cslu cslu-local
license smart usage interval 30
license smart vrf management
no license smart source-interface

Here’s the show license status output BEFORE configuring smart licensing.

This is what you should see AFTER you configure Smart Licensing on a Cisco Nexus switch. The Trust Code should update in about ten seconds, but the Usage Reporting section should completely update in about ten minutes.

nexus-switch# 

This command allows to unregister the switch.

license smart deregister

But now, how do you obtain the token to register with the Smart Account?

How to Create a Smart Account Token?

For Cisco partners, you need to request access to your customer’s Virtual Account. Your customer needs to go to https://software.cisco.com, scroll to Account Administration and click on Manage Account. Click on Users and then the Add Users button.

Once you have access, go to https://software.cisco.com and log in. You’ll need your Cisco username and password. Once on the home page, click on Manage Licenses under Smart Software Manager.

Click on the Inventory link and then on the New Token button.

Add a Description, the number of days you’d like this token active, and how many times you’d like to use this token when registering Cisco equipment. For instance, I normally use a token per device, so if I have two core switches at Site A, I create two tokens, one for Site A Core-A and another one for Site A Core-B. Each token with a Max. Number of Uses of 1; however, you could use the same token for both core switches and have a Max. Number of Uses of 2. I try to add a description that tells me in the future where I used that token.

After you click on the Create Token button, you’ll land back at the previous screen. Click on the little blue box with a white arrow to copy the token.

Now you can use this token in the script I gave you in the previous section.

  1. Thanks very much for these smart licensing guides, Cisco’s own documentation, especially for those of us using an on-prem license server, is pretty awful

    • Hi Andy. After going through these hurdles, I try to break them down and post them in easy-to-understand articles. I’m glad they help. Thank you!
