Automatic Discovery is the simplest way of discovering devices on network, due to minimal input to Discovery. IP Address is alone enough to initiate the discovery and all other inputs will come from System Default Parameters.
From the “Discovery” menu click “Automatic Discovery”.
Follow the below steps to initiate Discovery:
Provide the IP address(s) in the given textbox
Input can be a single Device management IP Address or “list of Device Management IP Address separated by comma or semicolon or single space” or Device IP address in CIDR format
Select the NCCM Process where it should managed
Manage includes Configuration Download, Device Inventory, Operation Data Download and Configuration Upload
Select the Notifier profile for the Device, so that Download events (failed to download, configuration change, Syslog) will be notified to users configured in the notifier profile
Select Device credential Profile (only if the Range of Input Devices has same credential to manage) or keep it as Select Device Credential profile. NCCM will automatically find the right profile for each device during discovery
Select Configuration profile (only if the Range of Input Devices can have the same profile to manage) or keep it as ‘Select Configuration Profile’. NCCM will automatically find the right Profile for each device during discovery
Select Connection protocol (for all the Range of Input Devices which can have same Connection protocol) or NCCM will automatically set the default connection Protocol from System Parameters
Select Running Configuration Download protocol (for all the Range of Input Devices which can have same Configuration Download protocol) or NCCM will automatically set the default Download Protocol from System Parameters.
Select Startup Configuration Download protocol (for all the Range of Input Devices which can have same Configuration Download protocol) or NCCM will automatically set the default Download Protocol from System Parameters.
Select OS Image Download Protocol (for all the Range of Input Devices which can have same OS Download protocol) or NCCM will automatically set the default OS Download Protocol from System Parameters
Select Inventory Download protocol (for all the Range of Input Devices which can have same Inventory Download protocol) or NCCM will automatically set the default Inventory Download Protocol from System Parameters.
Select other configuration Download protocol (for all the Range of Input Devices which can have the same other configuration Download protocol) or NCCM will automatically set the default other configuration Download Protocol from System Parameters.
Select or deselect filter by ping
If Filter by Ping is enabled then NCCM will filter the PING response devices and send those Devices for Discovery process.
If Filter by ping is not selected then NCCM will send all devices IP to Discovery process for SNMP Scan. Discovery could take more time when it discovery’s not PING devices.
Select Ping Time (in seconds). This will be used only when Filter by Ping is enabled.
Click ‘Discover’ to start the process immediately. Click ‘Cancel’ to abort the operation.
Discovery Progress and completion summary reports the count of Success and Failure devices through specific Discovery Protocols.
On Successful discovery, Download Jobs (per device) will be created automatically with inputs given on Discovery Page and from System Default (like Schedule for each Job as Daily 10 AM), and the Configurations, Operational Data’s will be downloaded immediately.
Devices Grid page will list out all discovered Devices with inventory and configuration details.
click “Automatic Discovery”.
