Your company should have a scalable and flexible network, and you can achieve that goal by having a hierarchical, layered design.Today, switches are not only Layer 2 devices, many of them are capable of performing Layer 3 features. With some Cisco switches, you can reallocate system resources in order for the switch to optimize support for specific features. This reallocation is done through changing of the SDM template. For example, if you want to implement IPv6 addressing on an access layer switch, you will need to change the SDM template. Cisco Discovery Protocol is a great tool to perform network discovery, but it is a Cisco proprietary solution. LLDP is a standard alternative to Cisco Discovery Protocol. PoE is a LAN technology that allows you to supply devices, such as IP phones and wireless APs, with power over an Ethernet cable. Supplying the device with power over the same cable as data eliminates the need for a power adapter, lowers the cost of implementation, provides easier maintenance, and provides greater installation flexibility than with traditional wiring. This course begins with an overview of all the components associated with a well-designed campus network. This course also explains the difference between Layer 2 and multilayer switch operation, how to change and verify the SDM template, and how to enable and verify LLDP neighbors. Lastly, this course will cover PoE and how to verify power consumption on a switch. This course offers the official training for the Implementing Cisco IP Switched Networks 2.0 certification exam which is a component exam for the CCNP and CCDP certifications. Passing this exam will also refresh CCNA certification, which expires after three years.

Target Audience
This course is intended for students who are looking for real-world switching knowledge, and those that are considering CCNP and CCDP certification. This course's discussion of switching could also benefit early CCIE Routing and Switching candidates.
