I've had NPM discover several ASA 5506's, and when I managed them with NPM I forced NCM to use the Adaptive Security Appliance template.
But still NPM shows "Wireless Controller" as the type of network device, when these have no wireless capabilities.
How does one inform NPM these are ASA's, not WLC's? Wait for a new version of NPM to come out, so there are new MIB's?
