Switching Infrastructure Connectivity

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

Overview

Merely interconnecting all devices via full duplex Ethernet does not allow for fault tolerance. Providing alternative pathways is part of the core deployment model of a Cisco architecture, but it must be managed with Spanning Tree protocol to avoid the catastrophic looping issues that go hand-in-hand with Ethernet switching redundancy. Although Spanning Tree protocol is often necessary, it can prevent the usage of parallel links. EtherChannel allows the usage of parallel links in an environment where STP is eliminating redundant pathways. Knowing how to work with these technologies allows a network engineer to build a redundant Ethernet network that can be scaled with port aggregation technologies. This course covers configuration aspects of switch connectivity such as speed and topological selection induced by STP and EtherChannel. This course is one of a series in the Skillsoft learning path that covers the objectives for the Cisco exam Building Cisco Service Provider Next-Generation Networks Part 1 exam (640-875 SPNGN1). This exam counts toward the CCNA Service Provider certification.

Target Audience

This course is targeted at networking engineers who must interface with Cisco IOS, IOS XR and IOS XE devices. Additionally, those who have a need to understand technologies used in the service provider realm will benefit.

Prerequisites

None
