The **Network topology** screen draws the physical network as the network itself reports it — what is behind this switch, what this desktop is plugged into. Open it from **Assets → Topology**. If you don't see this in your navigation, your administrator can switch the module on under **Administration → Modules**, or it may not be included in your plan. It is part of **IT asset discovery** there. The topology map centred on a core switch, with its ports listed in the panel beside it The topology map centred on a core switch, with its ports listed in the panel beside it The map is built from what [discovery](/assets/discovery) collects from network equipment: the neighbours each device announces on its ports (by LLDP or CDP) and the addresses each switch has learned on its ports. Nothing here is drawn by hand. ## The header | Figure | What it counts | | - | - | | **devices on the map** | Devices currently drawn | | **connections** | Links currently drawn | | **not yet discovered** | Neighbours announced on a port that no sweep has found | ## Choosing what to draw | Control | What it does | | - | - | | **Around a device** | Centres the map on one device. Empty (**The whole site**) draws everything | | **How far** | Appears once a device is chosen: how many connections out from it to draw | | **Site** | Limits the map to one site. Empty means **Every site**. Hidden while the map is centred on a device | | **Show desktops, printers and phones on switch ports** | On by default. Turn it off to draw only the network equipment and the links between it | A very large network is cut at a maximum number of devices; the screen says so, and centring on a device shows the rest around it. ## Map How to read it: | On the map | What it means | | - | - | | A coloured outline | Network equipment — switches, routers, firewalls, access points | | A dotted outline | A device not yet linked to an asset | | A solid line | A link between two pieces of network equipment, labelled with the ports at each end | | A dashed line | A device on a switch port | | A dashed amber outline | A neighbour that announced itself but has not been discovered | The shape tells you the kind of device. Click a device to open its panel: | Part | What it shows | | - | - | | **Kind** | Switch, router, firewall, access point, server, virtual machine, printer, laptop, desktop, phone, storage, or device | | **Reports itself as** | Its make and model as it reports them | | **Address** | Its IP address | | **Asset** | The linked asset, as a link, or **not linked to an asset** | | **Connected ports** | How many of its ports have something discovery knows connected, and a table of each **Port** and what it is **Connected to** | **Centre the map here** makes that device the centre. ## Links The Links tab listing each connection The Links tab listing each connection Every line on the map is a row here, so the network can be read without the drawing. | Column | What it shows | | - | - | | **One end** / **Other end** | The two devices, with the port at each end where known | | **How it is known** | **LLDP** or **CDP** (the devices announced each other), or **on a switch port** (the switch learned the device's address on that port) | | **Since** | When the link was first seen | | **Asset relationship** | **recorded** when the connection is also recorded between the two assets in the register | **Show on the map** switches to the map, centred on the device at the first end and with its panel open. ## Not yet discovered Announced but not discovered: a switch heard by CDP on a core switch port Announced but not discovered: a switch heard by CDP on a core switch port **Announced but not discovered** lists network equipment that announced itself on a discovered device's port and that no sweep has found. Each is an address worth authorising a sweep of; once it is discovered, the cable to it is drawn. | Column | What it shows | | - | - | | **Name** | What it calls itself | | **Address** | Its announced IP address | | **Platform** | Its make and model as announced | | **Heard on** | The device and port it was heard on | | **By** | LLDP or CDP | | **Last heard** | When it last announced itself | Seeing this screen needs permission to view scans, discovered devices and the software found on them.
