You are the network administrator for a growing business. When you were hired, the organization was small, and only a single switch and router were required to support your users. During this time, you monitored log messages from your router and switch directly from each device's console. The organization has grown considerably in recent months. Now you manage eight individual switches and three routers. It's becoming more and more difficult to monitor these devices and stay on top of issues in a timely manner. What should you do? Use Syslog to implement centralizaed logging. Use a remote access utility, such as SSH, to access router and switch consoles remotely. Consolidate network resources down to one or two switches. Hire additional resources to help monitor and manage your network infrastructure.
