Discovering Networks Using OpManager Plus

 

You can discover devices on a network by either specifying a range or the entire network

OpManager Plus uses ICMP/Nmap to discover the devices on a network.

  1. Discovering devices from an IP Range
  2. Discovering a complete network
  3. Discovering devices by CSV import
  4. Discovering Interfaces
  5. Scheduled discovery

Discover a Range

To discover devices from a selected range specify the start and end ip address and select the netmask for the devices to be discovered within that range.

  1. Go to Settings > Discovery > Discovery - Input
  2. Select IP Range: Select this option to specify the range.
  3. Start IP: Specify the IP address of the device in the range from where OpManager Plus should start discovery.
  4. End IP: Specify the IP address till which OpManager Plus should discover.
  5. Netmask: Select the correct netmask.
  6. Discovery Credentials: Select the configured Credentials to be used for discovery.
  7. Click Discovery for the discovery to start.

 

Discover a complete network

  2. Select CIDR: Select this option to discover an entire network.
  3. Network IP: Specify the Network IP to be discovered.
  4. Credentials: Select the credentials and SNMP settings as mentioned above.
  5. Click Discovery for the discovery to start.

Discover by Importing from a file

You can import a set of IP addresses for discovery from a csv file.

  1. Go to Settings > Discovery > Discovery - Input
  2. Select CSV File Import
  3. Create a csv file (as shown below) with the details of name/ipaddress of the device, displayname and device type.
  4. Browse and select the CSV file from which you want the devices discovered and imported.
  5. Provide the correct netmask.
  6. Click Discovery for the discovery to start.

Note: If you are using DHCP protocol on your network, make sure that both the forward and reverse lookup gets resolved before you add the devices to OpManager Plus.

 

Discover Interfaces

  1. Go to Settings > Discovery > Discovery - Interface
  2. Select Category, Devices, Interface Type and Status
  3. Click Discover to discover the interfaces

 

 


Scheduled Discovery

  1. We can have Opmanager Plus do a scheduled discovery at specific intervals which sweeps the IP range you entered and adds the devices using the conditions mentioned during the discovery.
  2. This can be saved as a profile to be executed per schedule and the report can be e-mailed as well.
  3. We can have Discovery reports which gives you information on what device was added and when.
