New Cisco devices showing as "Wireless Controller"

Hi All,

Using NPM 11.5 I've added 3 new devices this week, 2x Cisco Nexus 56128P switches and a Cisco 897VM-M router.

All 3 devices are showing up under "Cisco" without a model type and when you click on them, the device type shows as "Wireless Controller" (which can be edited). The main issue is that I'm having to customise the node screen to add in the standard things like Interface monitoring, also it isn't pulling the serial number. In the case of the 897 router, it's not able to monitor hardware stats either.

Any help would be greatly appreciated.
