This 2-day course provides a foundation for understanding
router and switch configurations and for enabling routing
protocols used in today's networks. Compare and contrast
the performance, overhead, routability, and integrity issues
surrounding today's major LAN/WAN protocols.
Objetivos
You will learn :
To enable Spanning Tree for network loop protection
Protocol structure and terminology
Subnetting and address masking
To configure VLANs to isolate broadcasts within different
domains
How to analyze and decode network traffic to optimize
LAN and WAN performance
To configure DHCP for IP address assignment on workstations
and routers
Key features of the OSPF, PPP,
Frame Relay, and HDLC wide
area protocols
¿A quién se dirige este curso?
Networking professionals who need a fundamental understanding
of today's major protocols.
IT managers, network administrators, network designers, network
engineers, technicians, telecom managers
