Continuous access to applications, data, and content demands a network wide resilience to increase IP network availability. A high-availability network is achieved by applying network-level resiliency, system-level resiliency, management, and monitoring. Network-level resiliency is achieved by adding redundant devices and connections into the network. System-level resiliency is achieved by adding redundant modules, such as power supplies, supervisor engines, and other components, to a modular device. Added redundancy often results in added complexity of the network. Complexity of the network can be reduced by the implementation of switch virtualization. Management and monitoring systems alarm the network operators, so they can respond to network and system outages and place appropriate actions to prevent a network QoS reduction or downtime. Different tools and features are available to monitor and manage network devices, traffic flows, and consistency with the SLAs. The course covers how to configure NTP and SNMPv3. It also covers how to configure a basic IOS IP SLA for network monitoring, local and remote SPAN and how to verify switch virtualization. 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.
