Topology
L2 Physical
How your network is physically wired.
The L2 Physical perspective shows the cable-level shape of your network — which device is plugged into which port on which switch. It's built from LLDP and CDP neighbor data, so any device that reports neighbor information appears as a container in this view, with its interfaces and ports as nodes inside.
What you see
- Containers: Devices that report LLDP/CDP neighbors — typically managed switches and routers
- Nodes: Their interfaces and ports
- Connections: Physical links, derived from each side's neighbor table
What drives it
LLDP and CDP run on managed network gear. When Scanopy queries a device with valid SNMP credentials, it pulls the neighbor table and uses it to draw links between interfaces. Devices that don't report neighbor data simply don't appear here — that's expected for unmanaged switches and most endpoints.
When to use it
- Troubleshooting connectivity at the cable level
- Planning physical changes (port moves, recabling)
- Auditing port utilization and trunk configuration
