The multi layer topology

One drawing, layers you turn on and off, built from what your devices say about their neighbours.

At a glance

  1. WhereInventory, then Multi-Layer Topology.
  2. AccessNeighbors module and the permission to view topology.
  3. DataCDP and LLDP for links, routing and transport protocols for their layers.

The demo estate's multi layer topology.

What the screen shows

The layers

L2 discovery (CDP, LLDP, interface names, VLANs), Spanning Tree (port states, root, instance), L3 routing (OSPF, EIGRP, BGP, IS-IS, IPv6), VPN and transport (tunnels, xconnect, VPLS, LDP, VXLAN, EVPN).

View options

Subnet hulls, external devices (off by default here), hide orphans, zones, IP phones, access points, icons by type or vendor, protocol colours, busiest uplinks, new and lost links.

A device's panel

Click a node: overview, interfaces, neighbours, services, routes. A route trace is available from the page.

What you can do

  1. 1

    Save a view

    Save as keeps the layers and filters. A view over all devices is shared; a view pinned to some devices stays with the active tenant. Built-in views cannot be edited.

  2. 2

    Arrange the drawing

    Move nodes: positions are kept server side, with a history; Reset starts over. Positions and zones export and import as a file.

  3. 3

    Export

    PNG, SVG, PDF or .drawio from the toolbar.

Limits and things to know

A device shows without links

Links come from CDP and LLDP. A device that does not run them has no neighbours; collect its neighbours too.

The other topologies

Neighbors Topology and the L2 Services point to point topology are BETA pages. Each protocol page also has a Topology tab filtered to its layer.
