Run Network Discovery

The Discovery Sessions page searches a network and discovers devices. A discovery session:

• Can automatically provision discovered devices with tests and start monitoring them immediately.
• Can be scheduled on a recurring basis.
• Should be limited to class-C networks instead of class-B or larger.

Prerequisites

Discovery requires the appropriate shared credentials be defined for the networks you want to scan.

Procedure

1. Navigate to the Administration > Discovery page.
   • A list of existing Discovery sessions displays.

   

2. Click the add icon, then click the Network Discovery icon.

   

   The Create Discovery Session dialog displays.

   

3. Enter the following values:
   • Department
   • Discovery Name - Enter a name.
   • Discovery Location - Your DGE extension was assigned a unique location when it was installed. Select it from the drop-down list. Most private networks use the same range of IP addresses. This is how Traverse identifies which network you want to run Network Discovery on.
   • Discovery Type - Network
   • Network Scan Range - Enter a network subnet starting value followed by the network mask. Example: 192.168.1.0/255.255.255.0. The DGE extension you installed must have network access to the range of IP addresses you specify.
   • Perform Discovery on a Schedule - If checked, enter the number of intervals to wait between recurring discovery session runs.
   • Start Monitoring Discovery Immediately - If checked, newly discovered devices are provisioned with tests, becoming managed assets, and begin being monitored immediately. If unchecked, devices are discovered but not yet provisioned.
4. You can now click Apply or...
5. Click Advanced to enter values in these optional fields.

   Note: Ignore these advanced features for your first run of network discovery.

   • SNMP Community Strings/Credentials - Optionally toggle each SNMP credential to include or exclude it from the discovery session.
     • Bolded text means the credential is included.
     • Unbolded text means the credential is excluded.
   • VMware Hypervisor Credentials - Optionally enter a VMware credential to discover additional information about VMware hypervisors.
   • Filter by Device Type
   • Physical Connectivity - Topology
     • Discover new devices and new/updated topology
     • Update topolog information for provisioned devices only
   • Seed Router - Discover connected devices from following 'seed' router (must be SNMP enabled)
     • IP address of seed router
     • Limit search within number of hops
