Local Time with Timezones over NTP Bundle lab · $29.99
Two-router /30 point-to-point lab. R1 is an authoritative UTC NTP master (stratum 3). Configure R2 as an NTP client to R1 and display local time in MST/MDT while remaining synchronized to UTC. Reinforces that NTP distributes UTC and the router applies timezone/daylight-saving only to presentation.
Learning objectives Configure a Cisco IOS router to synchronize its clock using NTP to a reachable authoritative master Apply a local timezone offset for display without altering the underlying UTC timebase Enable recurring daylight-saving time (summer-time) so the displayed time automatically adjusts Verify NTP status and local-time presentation with show commands Troubleshooting focus Confirm L2/L3 reachability on the /30 point-to-point link before blaming NTP Understand that NTP distributes UTC; verify timezone/summer-time for local display Allow time for NTP to select and mark a source; grade by configuration presence, not by convergence Check for typos in timezone sign (west of UTC is negative) and daylight-saving rule syntax What's included in the package Work / baseline CML import — lab-work.yaml Topology diagram — topology.svg Print-ready topology diagram (PDF) — topology.pdf Step-by-step learner guide (Markdown — for Obsidian/VS Code) — lab-guide.md Branded PDF lab guide — open in any viewer (Adobe/Preview) — lab-guide.pdf Getting-started README — README.md Verification checklist — verification-checklist.md How this lab is graded Build it your way. Where a lab lets you choose a value — a VLAN name, an interface description — grading checks that you configured it, not which name you picked. Names that another line has to reference, like an ACL applied with access-class, are stated in the guide and do have to match.Addresses, modes and protocol keywords are exact. An IP address, a subnet mask, switchport mode trunk, an encapsulation — these carry the meaning of the lab, so they are graded as written in the guide.Grading reads your saved configuration. Export the lab from CML after you have configured it, and make sure anything you set is in the running-config — a change that only exists in a terminal session never reaches the grader.You can submit as many times as you like. Your best score stands, and each attempt tells you which checks passed so you can work the gaps.Scored something you believe is correct? Use Report an issue on this page — that is exactly how the grading fixes in the changelog got found. Download access New here? See how the download → build in CML → grade loop works.
