Summary
LAN Design
Process that explains how a LAN is to be implemented
Factors to consider in LAN design include
Collision domains
Broadcast domains
Network latency
LAN segmentation
Summary
Switch forwarding methods
Store & forward – used by Cisco Catalyst switches
Cut through – 2 types
Cut through
Fast forwarding
Summary
Symmetric switching
Switching is conducted between ports that have the same bandwidth
Asymmetric switching
Switching is conducted between ports that have unlike bandwidth
Summary
CISCO IOS CLI includes the following features
Built in help
Command history/options
Switch security
Password protection
Use of SSH for remote access
Port security
