What does SNMP add over a normal scan?

The switch's own knowledge. A bridge-table walk tells you which physical port an address lives behind — information no amount of pinging from outside will produce.

Is it overkill for ten devices?

For discovery, yes. Its audience is people who cable patch panels and need the map to be correct in a year, not people counting phones on WiFi.

What should I configure before the first run?

SNMP read access on every switch, at minimum a community string for lab gear or SNMPv3 credentials anywhere serious. Without it the port mapper has nothing to correlate.

Engineer's Toolset: when the LAN pays your salary

The Toolset is not a faster version of the free tools — it is a different instrument. This entry logs what it adds once you manage switches: SNMP correlation, port maps and answers that survive staff turnover.

Switch Port Mapper view in Engineer's Toolset — The question it answers: which physical port is this address behind?

The thing free tools cannot do

Ping from outside tells you an address exists. The switch's bridge table tells you which port it lives behind — and only SNMP walks that table. The Port Mapper joins ARP data with the bridge table and prints a map from address to wall socket. When a colleague asks "where is this printer physically plugged in", the answer takes a click, not a crawl under desks.

Ping Sweep in Engineer's Toolset — The sweep inside the Toolset: familiar output, professional surroundings.

Before the first run

SNMP read access on every switch, without exception: a community string for lab gear, SNMPv3 credentials anywhere serious. The Toolset is a fine instrument, but it cannot correlate tables it is not allowed to read. Sort credentials first and the rest of the evening is quiet.

Home networks, skip this. The licence price assumes professional use. A home router offers nothing to correlate; a free sweeper answers the home question completely. Come back when there is a patch panel in your life.

What it is not

Not a monitoring platform. It diagnoses and documents on demand; continuous watching is a different product. Teams that need both usually run a monitoring platform next to it — the Toolset's job is the map, not the alarm.
