 | Ethernet Cables: Crossover Cables and Straight Through Cables
Ethernet cables and understanding how to hook up network devices via crossover cables and straight through cables is essential to any networking engineer or Cisco certification student. After watching this short microlearning IT training video, you’ll be able to connect network devices with confidence. Brought to you as part of the Cisco Answers IT video training series. | 00:04:15 | |
 | Crossover Cables and Straight Through Cables Test Yourself
Crossover cables and straight through cables, time to test yourself on how well you understand when to use which ethernet cable as part of your network. Previous IT training videos in the Cisco Answers IT series will help you if you have any difficulty with this test. | 00:03:01 | |
 | RJ45 Connectors, RJ45 Wiring, Unshielded Twisted Pair (UTP) and More
Another microlearning IT training video on ethernet cables. In this short educational piece, we look the cable ends and the wiring inside of standard ethernet cables. What is an RJ45 connector? What does unshielded twisted pair mean? How are RJ45 connectors wired? Another microlearning piece of education for your busy day as part of the Cisco Answers IT Microlearning video training series. | 00:04:37 | |
 | Configuring OSPF
In this video, Cisco Technical Leader Raymond Viscaina demonstrates basic configuration of Open Shortest Path First (OSFP). OSPF, an Interior Gateway Protocol (IGP), facilitates communication between multiple networks by exchanging routing information between gateways. Raymond utilizes 3 Cisco routers and 3 Cisco switches interconnected with the use of Ethernet and Serial cables to create a meshed environment. Raymond sets up the various interfaces with unique IPv4 addresses and subnet masks by operating within the Cisco Command Line Interface (CLI). Raymond then advertises the newly created networks and verifies successful communication throughout the environment using a ping test. | 00:02:45 | |
