Basic Understanding of Core Switch.pdf

Core switch is designed to meet the most demanding enterprise network requirements such as reliability, high speed, and scalable. It supports the next-generation Ethernet speeds with 10/25 Gigabit Ethernet at the aggregation and 40/100 Gigabit Ethernet to meet the high volume of traffic driving from the edge into the core. This article provides some understanding of core switches.
