Nexus Dashboard Controller License Consumption

Nexus Dashboard controller license consumption

Nexus Dashboard (ND) controller or cluster is bundled with Day2Ops applications. These applications request for controller licenses such as controller-ess, controller-adv, or controller-pre from the NX-OS switch. Based on this request, the corresponding licenses such as NXOS_ESSENTIALS, NXOS_ADVANTAGE, or DCN_PREMIER are used on the switch.


Note

If you downgrade from NX-OS Release 10.5(2)F to a lower image version, and upgrade to the 10.5(2)F or later versions, you must verify the controller license again.

You can verify the license usage using the show license controller usage or show license usage commands.

This is a sample output for show license controller usage command. 

switch# show license controller usage 
cluster01
NXOS_ESSENTIALS: TRUE
NXOS_ADVANTAGE: FALSE
DCN_PREMIER: FALSE

cluster02
NXOS_ESSENTIALS: FALSE
NXOS_ADVANTAGE: TRUE
DCN_PREMIER: FALSE

cluster03
NXOS_ESSENTIALS: FALSE
NXOS_ADVANTAGE: FALSE
DCN_PREMIER: TRUE

This is a sample output for show license usage command.

When the feature is enabled on the NX-OS switch with the license feature on the ND controller side, the highest between the two licenses is used. This is a sample output that depicts this scenario.
