Cisco ICND2 1.1: Implementing VLANS and Trunks

This course is included in our On-demand training solution.


As small networks grow and become more complex, greater functionality and control over network components (delivered through more sophisticated network devices such as switches and routers) becomes critical. Most Cisco hardware platforms implement Cisco IOS Software, including switches and routers. This software enables network services in Cisco products, including carrying the chosen network protocols and functions; controlling access and prohibiting unauthorized network use; and adding interfaces and capability as needed for network growth. You use the command-line interface (CLI) of the Cisco IOS Software to enter the configuration details into the Cisco switches and routers that implement the network requirements of an organization. This course provides a review of the Cisco IOS command-line interface (CLI) structure and the Cisco IOS commands that are used to create a basic router and switch configuration.
A VLAN is a group of end stations with a common set of requirements, independent of their physical location. A VLAN has the same attributes as a physical LAN, except that it lets you group end stations even when they are not physically located on the same LAN segment. A VLAN also lets you group ports on a switch so that you can limit unicast, multicast, and broadcast traffic flooding. Flooded traffic that originates from a particular VLAN floods only to the ports belonging to that VLAN. VLAN trunks with IEEE 802.1Q tagging facilitate interswitch communication with multiple VLANs. Cisco Catalyst switches feature VLAN Trunking Protocol (VTP) to simplify management of VLANs across multiple switches. Understanding the operation of VLANs and the associated protocols is important for configuring, verifying, and troubleshooting VLANs on Cisco access switches. This course also describes VLAN operations and their associated protocols.

Target Audience

Anyone wishing to obtain the Cisco Certified Network Associate (CCNA) certification that validates the knowledge and skills required to successfully install, operate, and troubleshoot small to medium size enterprise branch network. Network administrators, network engineers, network managers, network designers, and project managers. Candidates who have completed the 640-822 Interconnecting Cisco Networking Devices Part 1 (ICND1) exam associated with the Cisco Certified Entry Network Technician certification which is the first step in achieving the Cisco Certified Network Associate certification.
