Discover

Discover is the application for Corporate Networks that inspects and identifies the network topology, generating adequate documentation for equipment analysis, resource use and change management.

Resources

Discover allows you to obtain a breakdown of the infrastructure resources consumed and collects the following data

Identification of all allocated IP addresses in use to obtain allocated L3 resources.

MAC

Identification of MAC addresses and the Ethernet interface manufacturer database. Universal and local addresses, normally used by virtual machines, are also identified.

Graphic

Creation of a Network Diagram correlating interconnection points, interfaces, speed and their state: active, inactive or standby.

Equipments

Identification of network equipment through sysDescr, evaluating and classifying the types of equipment on the network: routers, switches, controllers, APs, telephones, printers, servers and workstations. For each network element, obtain correlated data and aggregate data for the topology survey.

Router

Model, version, firmware, uptime, hardware configuration and connected networks

Switch

Model, version, firmware, uptime, hardware configuration, uplink ports, spanning-tree data

WiFi Controler

Model, version, firmware, uptime, hardware configuration, AP data (if available in manufacturer's SNMP)

Requirements

The following requirements must be configured on the target network before Discover can be applied

Access

Access through a list of users/passwords/IP, or use of a single authorized account to execute all equipment query commands

Manageable Equipment

Network equipment must be managed to obtain topology data and/or interconnection documentation. If unmanaged concentrator equipment is used (e.g. switches), the topology will identify all connected equipment as being an undefined cloud

Community

Community SNMP for configured reading

SSH

SSH released for access to network equipment and limited Linux machines for querying resources used

Windows

For Windows machines, the availability of a Microsoft SNMP agent and “read-only” community query release is essential.

CDP and LLDP

The use of CDP and LLDP is highly recommended. Through the use of CDP and LLDP in network equipment, the determination of uplinks, ports and topology is very precise. CDP is available on all Cisco equipment and also on equipment from Meraki, HP, Aruba, Palo Alto, etc. LLDP is used by Dell, Juniper, CheckPoint, etc. equipment. Both protocols run exclusively on network infrastructure equipment.

Firewall

Lista de redes que devem ser avaliadas no Discover e ponto inicial de varredura. Devido ao uso de firewalls ou de redes de operadoras o “discover” pode não ser capaz de ultrapassar os limites das bordas dos perímetros. Assim, cada rede será avaliada individualmente.

On the Fly

The software runs on a single Linux virtual server and data is stored in a database. The database maintains the entire execution history and can be consulted to evaluate changes and possible equipment insertions.

The entire operating interface is carried out through a “browser” where the information for executing and viewing reports and diagrams is configured.
