One of the keys to understanding Cisco is the OSI model. The OSI model permits people to understand how internetwork works and it serves as a guideline or framework for creating and implementing network standards, devices, and internetworking schemes. Some of the advantages of the OSI model include: • It allows for the breaking down of complex operation into simple elements; • Enables engineers to specialize the design and development of modular elements; and • It provides standards for plug and play and multivendor integration | 640-607 fest kino LEODrMQ THE LuftM IM IT TESTING HM CEFJTIEICnTlIDM TdDLEl Study Guide Cisco Certified Network Associate CCNA Version 1 -1- 640-607 CCNA OSI Upper Lower Data Link Layer Network Layer Transport Layer LAN Physical Layer CISCO DEVICE Command Basis Switch Switch Configuration using the Command Basic Router Common CLI Error Basic Router Advance Router OBTAINING NETWORK CDP Related Telnet Router Router CATALYST 1900 Frame Avoiding Spanning Tree Spanning Tree Path Spanning Tree Protocol Spanning Tree How Frame Are Switch Catalyst 1900 Switch Configuration Virtual TCP TCP Connection TCP IP Internet IP Addressing -2- 640-607 Address Configuring IP ROUTING Route Routing Administrative Routing Protocol ACCESS Access List Access List Standard IP Access Extended IP Access Verifying and Monitoring Access NOVELL INTERNETWORK PACKET EXCHANGE IPX PROTOCOL SUITE .47 Encapsulation CISCO AND WIDE AREA NETWORK WAN .50 WAN Connection WAN Layer 2 FRAME Subinterface Connection Obtain Frame Relay Lab 1 - Configure a name and passwords for a Lab 2 - Configuring Router Lab 3 - Configuring Static Lab 4 - Configuring RIP and Restoring Lab 5 - .
