Under Maps you open three maps: IP Segments, IP Networks and Topology. All three draw the same captured devices, but for three different questions—which distributors connect the segments, which devices sit in which segment, and how the devices are physically connected.

IP Segments

IP Segments shows the IPv4 segments and the distributors between them. A Segment is an IPv4 network address in CIDR notation. A distributor is a device with addresses in more than one segment—router, firewall or L3 switch. Only distributors are nodes here, the segments a distributor serves appear as connections between them. Every other device is contained in its segment and does not appear as a node of its own. Each segment carries a kind, shown in its detail area and derived from its address and the number of distributors on it: A firewall acts as a policy boundary; every other distributor—router, L3 switch—connects segments without a rule. If the map does not recognize a firewall, it shows it as an ordinary distributor. The detail area shows this as the distributor’s role. The role and the kind sit side by side in the same detail area but mean different things: the role of the distributor and the kind of the segment.

IP Networks

IP Networks shows every captured device at the IPv4 segments it holds an address in. Segment, kind and role work as in IP Segments. To keep the picture manageable, the map combines:
  • A segment with only its own devices is combined into a single entry—the network address in the header, one row per device, grouped by device type.
  • A redundancy pair of distributors appears as one Unit, a framed group.
  • Pure coupling segments on a single distributor are combined into one node from two upward.
IP Segments has neither the combined entry nor the Unit, because no device there sits in a single segment alone.
A device with no address in a known segment is counted but not drawn.
Neither IP Networks nor IP Segments checks whether two segments overlap or whether an address is assigned twice. Do not rely on these maps to find IP conflicts.

Topology

Topology shows every captured device and the connections between them—with bandwidth and ports. No segment orders the picture here; the connection alone does that. Each device appears as one of three forms: A firewall additionally carries an indented frame that marks it as a policy boundary. If the map does not recognize a firewall, it shows it as an ordinary device without that frame. Bandwidth always colors every connection by its speed class. The port names of a connection appear as soon as the pointer rests on it. Several connections between the same two devices appear combined as one line with a number. If a device carries ports, its detail area shows a section on port usage, and a button there opens a second column beside it: one tile per port, grouped by port group. A port without a fixed number sits at the end of its group, with a lightning bolt instead of a digit.

The shared toolbar

All three maps carry the same toolbar. A Preset saves a set of settings—arrangement, Starting From, location filter and the checkmarks of Display—but not the search text. It applies either to you alone or, with the Everyone badge, to every user of the data source; without the right to save for everyone, that choice stays visible but locked. If the map deviates from the applied preset, the button carries a dot. Without write permission in the area, the buttons for saving, editing, overwriting and deleting presets are missing; you can still apply a preset. Reset settings returns arrangement, Starting From, location filter, legend and Display to the state without remembered settings.

The legend

The legend is divided into named sections. The explanation of a row, such as how a Switch stack is drawn, appears as soon as the pointer rests on the row. In Topology, one section lists the forms—Switch, Switch stack, Several devices grouped and Access point and other devices—and another lists the bandwidth classes: below 1 Gbit/s, 1 to under 10 Gbit/s, 10 Gbit/s and above, and not reported. Moving around a map, selecting in it and exporting it work the same in all three—see Understanding Maps. The data for the maps is produced by scanning, see Scanning Fundamentals.
