Question about SLR - Authorization Code

[mhiyoshi]

Hi all,

Normally if the customers do not want to connect to the internet then SLR is one of options in my understanding.

So now I am looking at the the following URL which is about SLR operation below.

https://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst_slr/b-169-9000-series-SLR-cg/b-169-9000-series-SLR-cg_chapter_00.html#task_ukn_ldm_bfb

I would like to know if the device can generate the SLR Authorization code on CSSM.

Next step is to install the code to the devices such as Cat9K. 

However if the installation process is temporarily stopped then the code can be expired? 

If yes how long or it is not expired.

If there is any related CCO manual, please let me know.

Best Regards,

Hi,

However if the installation process is temporarily stopped then the code can be expired? 

No, you install the permanent license once and it will never expire, no mater how many times you upgrade the IOS.

Hi Reza,

Thank you for your support! I can understand that normally authorization code is not expired.

However actually is it about the perpetual Network Essentials & Advantages right?

How about DNA Essentials & Advantages which are subscription license for each 3,5,7 years.

Actually when the subscription licenses count start?
