Chapter 1 Overview
Network Configuration Examples
QoS and policing on the switches provide preferential treatment for certain data streams, if required.
They segment traffic streams into different paths for processing. Security features on the switch
ensure rapid handling of packets.
Dual homing of servers to dual switch stacks with redundant Gigabit EtherChannel and cross-stack
EtherChannel provide fault tolerance from the server racks to the core.
Using dual SFP uplinks from the switches provide redundant uplinks to the network core. Using SFP
modules provides flexibility in media and distance options through fiber-optic connections.
The various lengths of stack cable available, ranging from 0.5 meter to 3 meters provide extended
connections to the switch stacks across multiple server racks, for multiple stack aggregation.
