Port Security: Voice + Data on One Access Port

Harden a real desk port that carries both data (PC) and voice (IP phone) using switchport voice vlan and access vlan on a single access port. Apply port security with a maximum that accounts for two MAC addresses (phone + PC) so a third device is restricted. A deliberate trunk allow-list drift on the inter-switch link initially blocks the Voice VLAN; learners must repair the trunk and then verify port-security state on the desk port.

Port Security: Violation Shutdown & Manual Recovery

Hands-on CCNA L2 switching lab: build a small campus with a distribution switch and two access switches carrying a shared user VLAN over 802.1Q trunks. Harden access ports with sticky port-security in violation shutdown mode. Intentionally seed and diagnose broken trunks/host VLANs, restore end-to-end host reachability, then trigger a port-security violation to observe err-disabled behavior and perform manual recovery.

CCNA Port Security 2: Sticky Secure MAC Learning

Two access-layer switches have a VLAN 20 connectivity problem: users in one wiring closet cannot reach users in the other. Diagnose and repair the issue, then deploy sticky secure MAC learning on the host-facing access ports so each port dynamically learns and persists its connected host's MAC. Verify sticky entries in show commands and confirm same-VLAN host connectivity end-to-end.

CCNA: Native VLAN & Untagged Traffic on 802.1Q

Hands-on CCNA switching lab focused on the native VLAN and tagging behavior on 802.1Q trunks. Users in one VLAN currently cannot reach their peers across a switch-to-switch trunk; you will standardize the native VLAN away from VLAN 1 to a dedicated parking VLAN, diagnose and correct the trunk configuration, verify the untagged VLAN on both ends, and confirm same-VLAN host reachability across the trunk.

VLAN Trunking 6: DTP and Trunk Hardening

Hands-on DTP negotiation and trunk hardening across a 3-switch path. You will observe dynamic trunking behavior (auto vs desirable), fix an allow-list drift that blocks user VLAN transport, and then harden the trunks to static with nonegotiate and a non-default native VLAN. End-to-end host reachability in the same VLAN proves success.

Trunk Verification & Diagnosing a Silent VLAN

An advanced CCNA switching lab focused on verifying 802.1Q trunks and diagnosing a silent VLAN after a switch refresh. The topology uses three layer-2 switches (a distribution switch between two access closets) and two Alpine hosts, and users in VLAN 20 at one closet cannot reach their VLAN 20 peers at the other closet across the trunk path. Learners use show interfaces trunk, show interfaces switchport, and show vlan brief to locate the break and restore predictable Layer-2 forwarding without adding any Layer-3 configuration.

Trunking Basics: Access Ports vs Trunk Ports

Hands-on CCNA switching lab contrasting single-VLAN access ports with 802.1Q trunks. You begin with the inter-switch link configured as a plain access port, so only one VLAN reaches the router-on-a-stick gateway while the other cannot. You will diagnose the connectivity problem, convert the link into a properly hardened 802.1Q trunk, and validate that both VLANs regain access to their gateway.

CCNA VLAN Trunking 7: Trunking Across Three Switches

Build an end-to-end 802.1Q path across three Cisco IOS Layer-2 switches so VLAN 10 transports user traffic from an access port on the left switch to an access port on the right switch through a middle switch. Harden trunks (native VLAN 999, nonegotiate) and verify with show interfaces trunk. Then intentionally break the allow-list to see the outage and restore service.

Native VLAN Mismatch: Diagnosing a Broken Trunk with CDP

Diagnose and remediate a trunk misconfiguration between an access switch and a distribution switch so that same-VLAN hosts across two access switches can communicate end-to-end. Use CDP and trunk verification commands to investigate the fault and restore proper trunk operation, without introducing any Layer-3 routing.

Default Routes & the Gateway of Last Resort

Build a small hub-and-branch network to master default static routes and the gateway of last resort. Each branch uses a default route toward the hub; the hub holds specific routes back to branch LANs. Verify routing tables and end-to-end host connectivity, then troubleshoot common misconfigurations.

Static Routing Between Branches Through an HQ Hop

Deploy IP addressing and bidirectional static routing across a three-router topology to connect two branch LANs through an HQ hop. Practice verification from end hosts, analyze routing tables, and troubleshoot asymmetric reachability.

IPv4 Addressing Fundamentals: Interfaces, Gateways & Reachability

Beginner CCNA lab focusing on IPv4 addressing and basic Layer 3 verification on a small branch network. You will assign IP addresses to router interfaces, confirm end-host default gateways, and verify connected reachability using host-based pings. You will also learn to read 'show ip interface brief' and 'show ip route' to confirm operational state before any routing beyond directly-connected networks is configured.

What's unlocked, and what's free

Subscription access, and the labs that need none.

A subscription unlocks every lab on this page for as long as it's active — the whole daily back catalogue, not just the labs published after you join, plus every series lab. Bundles and study paths aren't sold separately; the subscription is the only plan.

Free labs need no subscription at all: every lab you can build and grade without one is the sample, plus the opening lab of each series.
