Network Inventory Checklist

Why Network Inventory Matters

Network infrastructure is the backbone of your IT operations. Yet most Indian SMEs do not have a complete inventory of their switches, routers, firewalls, and access points. When a switch fails, the IT team spends hours tracing cables and checking configuration backups. A proper network inventory reduces recovery time from hours to minutes.

Core Network Devices

• Router: Model, firmware version, WAN IP, ISP details, contract expiry, management interface IP.
• Core Switch: Model, software version, number of ports, VLAN configuration, stacking status, uplink speed.
• Access Switches: Model, location (rack/floor), connected devices count, PoE budget used/available.
• Firewall: Model, firmware version, throughput capacity, active rule count, VPN tunnel count, licence expiry.
• Wireless Controller: Model, managed AP count, firmware version, SSID configuration.
• Access Points: Model, location, channel assignment, signal strength at installation, connected client count.

Supporting Infrastructure

• Patch Panels: Location, port count, labelling scheme, termination standard (T568A/B).
• Cable Runs: Source patch panel / port, destination wall jack / device, cable category (Cat5e/Cat6/Cat6a), length, and testing certification reference.
• UPS Units for Network: Model, capacity (VA/W), battery age, runtime at current load, last battery replacement date.
• Server Room PDU: Model, input capacity, outlet configuration, load per phase, remote management capability.

Documentation Standards

Every network device should have: a label with hostname and IP address affixed to the device, a network diagram showing physical and logical topology (updated after every change), configuration backup stored in a central repository (not on the device itself), and console/management access credentials stored in a password manager.

Audit Checklist

• Physical verification of every network device against the register.
• Firmware version audit — are any devices running end-of-life software?
• Port utilisation audit — which ports are used, which are free, which are dead?
• Cable condition check — replace damaged or unlabeled cables.
• Environmental check — device temperatures, fan noise, dust accumulation.
• Configuration backup verification — latest backup stored and tested for restorability.

Review Cadence

Full network inventory audit biannually. Configuration backup verification weekly. Firmware review quarterly. Cable and environmental check during every site visit by a technician. Any network change (new switch, VLAN change, firmware upgrade) triggers an immediate inventory update.
