21. Switching Technology Comparison Dumb Line Card without capabilities to determine switching path All traffics MUST be processed by “Control Card” Switching performance relies on “Control Card” Packets always be transmitted back and forth between Control Cards and Line Cards Intelligent Line Card with capability to determine switching path Synchronized switch/route information on Control Card and Line Card Layer 2/3/4 Local on board switching capability Fastest forwarding, near zero-wait Centralized Switching V.S Distributed Switching Legacy Catalyst 6500 HP A7500 with SA mudules Product Overview

22. Ports Control Card Line Card Drawback of Centralized Switching All traffics MUST go through control card even traffic in/out on the same line card. 2 Route and VLAN forwarding information is stored in control card. Before sending packets, dumb line card needs to ask control card 1 Ports Poor performance is resulted from waiting transmit permit while sending packets 3 Product Overview
