Pick a ticket and fix it from the command line of a simulated access switch, ACCESS-SW-01. Abbreviations, ? and Tab work like the real thing. Run the right show commands, make the fix, and the ticket closes.
Tip: Enter runs · ↑ ↓ history · Tab completes · ? lists options · Ctrl+Z leaves config mode · pipes like | include work.
The switch state has to be fixed, and you have to have run the commands that prove what was wrong. The checklist ticks as you go. Hints are there when you're stuck.
A 48-port PoE access switch with PCs, IP phones, printers, two APs and a trunk to the distribution switch. Port security, BPDU guard, err-disable recovery, PoE budget, speed and duplex, VLANs and trunks all behave like the real thing. Output follows IOS XE formats; names, addresses and MACs are made up.
Each ticket links to the matching section of the Network Ops Analyst Field Guide. Start with its Quick Workflow: show interfaces status, then the MAC table, then neighbours.
