| 1. | - Five Crucial Commands for Verifying Cisco Switch Network Status and Operational State
- Aug 11, 2015
- A network engineer needs to be conscious of the state of the network and every device connected to it. But when your network consists of multiple devices connected at a distance, how can you test connections and keep on top of network performance? Sean Wilkins, co-author of CCNA Routing and Switching 200-120 Network Simulator, discusses five basic commands you need to know and use correctly to maintain your Cisco network.
