L2 Security Troubleshooting Capstone: Trust Boundary
Advanced Layer-2 security capstone. Neither PC on the access switch can get an address, and the help desk has already 'checked the DHCP server'. You get the symptoms and the requirements — no fault list. Work from show output to find every misconfiguration across the switch and the router, repair them, and prove both hosts recover. Several faults are layered: fixing the first one changes the symptom without ending the outage.
