NX-OS Nexus 7018 License-id for Chassis or Supervisor

[canero]

Hello,

For a single chassis supervisor, if we have license for  VDC for 7018 Chassis, and we want to change the single supervisor with a spare one,  can we install the backed-up license from the supervisor to the new supervisor. This is important because if the license is chassis based, we may be able to use the same license file for the spare supervisor, or if it is supervisor based we may need to contact TAC for a license rehosting procedure.

Also, if a grace period starts for a demo purpose, and after 120 Day grace period, is it possible to repeat the demo or poc with restarting the grace period, or a license needs to be bought?

Thanks in Advance,

Best Regards,

On the NX-OS Licensing guide it mentions about the serial number of the device (but we could not be sure if the device means chassis or supervisor)

Obtaining the License Key File

You can obtain new or updated license key files.

Procedure

---

Step 1

Obtain the serial number for your device by entering the show license host-id command. The host ID is also referred to as the device serial number. switch# show license host-idLicense hostid: VDH=FOX064317SQ Tip   Use the entire ID that appears after the equal sign (=). In this example, the host ID is FOX064317SQ.

License is based on chassis serial number seen under show inventory. If you look at the License file name it is named with chassis serial number. If you replace the supervisor you do not need to transfer license by calling TAC but you can copy the license file to new supervisor bootflash and run install license command from bootflash to install license into new supervisor.

Krunal is correct on the License Hostid. It is based on the chassis SN.

For grace period, the answer will be no, you cannot reset it. You will have get the permanent license if you would like to use it after the grace period expired.

Hello Jerry,

Thank you, so only time we need to rehost the license is during a chassis change,
