Scenario
Two persistence layers exist: - Running config — the live, in-memory configuration. Every command you type lands here immediately. - Startup config — what the box loads on boot. After making changes, you copy running-config startup-config (short: wr m / write memory) to make them survive a reload. Forget this and your "fix" disappears the next time the box reboots. Beyond CLI, netverdict's workspace also offers (without grading here): - ⤓ config in the Inspector side-drawer — downloads <hostname>-running-config.txt. - Save scenario — bundles topology + per-device CLI history into a .netverdict.json you can share or stash. - Export pcap — every frame the sim has captured, opens cleanly in Wireshark.
