What a strong network documentation & discovery engagement should achieve
Layer 2 and Layer 3 boundaries, routing, segmentation, resilience, internet edges, management access, addressing, DNS/DHCP dependencies and monitoring are designed as a system.
Discovery before change
Discovery includes topology, configuration, traffic patterns, critical paths, current faults and physical constraints. Changes are staged with explicit backout paths and validation of dependent services.
Designed to remain supportable
Configuration backup, monitoring, capacity trends, firmware lifecycle, diagrams and ownership standards are established so the network remains supportable after project completion.
A clear responsibility boundary
Work ranges from targeted remediation through full campus, multi-site and datacentre network programmes.
