Device Types

The Discovery app lists and analyzes the types of devices explained in this section. Different data may be available to the LR 10G depending on the device type, how it was discovered, and your configured settings.

For descriptions of the different Details cards and screens, see Discovery Details.

The images in the rest of this section show examples of data that Discovery may display for each device type.

Routers

LR 10G discovers IP routers by monitoring traffic and querying hosts.

Switches

Switches are also discovered by monitoring traffic and querying hosts.

Unknown Switches

Unknown switches are detected indirectly by analyzing traffic going through surrounding switches. The LR 10G cannot identify the switch, but it can sense where a switch is active on the network via the device MAC addresses in that space.

The LR 10G numbers the switches as they are discovered. (These numbers may change each time the discovery process runs.)

The Unknown Switches Details screen shows the number of devices connected to the switch. Tap the Connected Devices card to view the connected devices, which may provide clues about the location of the unknown switch.

Network Servers

Network servers include NetBIOS, DHCP, and DNS servers.

Hypervisors

VMware hypervisors are discovered via SNMP. The hypervisor's SNMP agent must be enabled for the LR 10G to discover it and classify it as a hypervisor.

Virtual Machines

VMware virtual machines are discovered from VMware client table in SNMP-enabled VMware hypervisors. Devices are also classified as Virtual Machines if they have a VMware MAC.

Wi-Fi Clients

Wireless clients are discovered through SNMP queries with a linked connection through a management or test port.

VoIP Phones

VoIP discovery provides visibility into the VoIP and layer 2/3 configuration of the network.

Printers

The LR 10G identifies IP printers via the SNMP Printer MIB and IPX printers via diagnostic requests and queries.

SNMP Agents

SNMP agents are discovered using SNMP queries. See SNMP Configuration.

NOTE: If LR 10G cannot discover the SNMP agents on your devices, they may be connected to another subnet, like a management subnet. Solve this issue by adding the subnet to Extended Ranges.

See also SNMP Details.

Network Tools

The LR 10G can also identify other NetAlly network testers, such as other EtherScope nXGs, AirChecks, CyberScopes, LinkRunners, and Test Accessories.

The image above shows several NetAlly tools as they appear in the main Discovery list.

LR 10G displays all the information it can gather about each tool on the Details screen.

Hosts/Clients

Other hosts and clients are discovered by traffic monitoring and querying. If a host cannot be identified as belonging to one of the other categories (Switch, Router, VoIP device, etc.) then it is categorized as Host/Client.

NOTE: A MAC address that begins with LocalAdm indicates that the address has been locally randomized to prevent unauthorized tracking.
