(CWNCM) Cisco Works Network Compliance Manager HA Licensing

In order to have high availability in a CWNCM environment you need both core licenses and high availability (HA) licenses. This is true for both the core software and also the node licenses.

So for example, if you want to manage 600 nodes and have HA servers you would need the Core and HA software license as well as 600 node and 600 HA node licenses:

CWNCM-1.7-CORE-K9
CWNCM-1.7-HA-K9
CWNCM-1X-INC100
CWNCM-1X-INC500
CWNCM-1X-HAINC100
CWNCM-1X-HAINC500

Please note CWNCM is now end of life, but I'm keeping note of this just in case... The recommended replacement is either Cisco Prime or to buy HPs Network Automation, CWNCM is an OEM of HPs network Automation product.
