Lab - Configure VLANs and Trunking
Part 1: Build the Network and Configure Basic Device Settings
Part 2: Create VLANs and Assign Switch Ports
Part 3: Maintain VLAN Port Assignments and the VLAN Database
Part 4: Configure an 802.1Q Trunk between the Switches Part
5: Delete the VLAN Database
Background / Scenario
Modern switches use virtual local-area networks (VLANs) to improve network performance by separating
large Layer 2 broadcast domains into smaller ones. VLANs can also be used as a security measure by
controlling which hosts can communicate. In general, VLANs make it easier to design a network to
support the goals of an organization.
VLAN trunks are used to span VLANs across multiple devices. Trunks allow the traffic from multiple VLANS to
travel over a single link, while keeping the VLAN identification and segmentation intact.
In this lab, you will create VLANs on both switches in the topology, assign VLANs to switch access ports,
verify that VLANs are working as expected, and then create a VLAN trunk between the two switches to
allow hosts in the same VLAN to communicate through the trunk, regardless of which switch the host is
actually attached to.
: The switches used with CCNA hands-on labs are Cisco Catalyst 2960s with Cisco IOS Release 15.2(2)
(lanbasek9 image). Other routers, switches, and Cisco IOS versions can be used. Depending on the model
and Cisco IOS version, the commands available and the output produced might vary from what is shown in
the labs. Refer to the Router Interface Summary Table at the end of the lab for the correct interface identifiers.
