Hi friend!
I have checked the diagnostic and normal commands and unfortunately, the display license information command doesn’t exist in the NE8000 X4 device.
A list with the license commands can be found here.
Note that in S12700 devices, the display license information command displays license information about the master and standby switches in a CSS system.
If a switch is not in a CSS system, the display license information command displays license information about the switch only. If a CSS system contains the master and standby switches, the display license information command displays license information about the master and standby switches.
Hope to help you!
