Serial Number Change Nexus 9000V

Hi All,

 

I installed a N9kV switch for vxlan testing, Requested License from Cisco licensing team and they provided me a demo license for about 60 days. At some point I reloaded the nexus switch it boots up with a new serial number and I lost my license. Every time I reload it comes with the new serial number.

 

Before reloading the switch:

Mod  MAC-Address(es)                         Serial-Num
---  --------------------------------------  ----------
1    00-0c-29-57-c3-9b to 00-0c-29-57-c3-e2  9PRNTDB91UF

 

After reloading the switch:

 

Mod  MAC-Address(es)                         Serial-Num
---  --------------------------------------  ----------
1    00-0c-29-57-c3-9b to 00-0c-29-57-c3-e2  9YB3J2F5HSC

 

Itseems the change in serial number only not in mac address and UUID . How to prevent this serial number change, I was banging my head to find the root cause for this. Any help would be greatly appreciated :)

 

N9kV version: nxos.7.0.3.I6.1.bin

 

Thanks and Regards,

Prem

It’s becuasue you don’t have a permanent license. The temporary license is only good tell the next reboot.
