You use Cisco Discovery Protocol (CDP) polling to allow FortiNAC to gather information about network devices more quickly and efficiently. Network devices that are configured for CDP collect and store information about the network devices they manage or can contact. Devices that have the capacity for CDP must have the feature configured on the device's firmware.
CDP polling is enabled by default.
- Go to System > Settings > Network Device.
- Select Enable Cisco Discover Polling.
- If required, select Maximum Cisco Discovery Depth set a limit for the number of layers from the FortiNAC that are queried.
- Select Save Settings.
