Cisco IOS Embedded Event Manager (EEM) is a powerful and flexible subsystem that provides real-time network event detection and onboard automation. It gives you the ability to adapt the behavior of your network devices to align with your business needs. Customers can use EEM to create and run programs or scripts directly on a router or switch. The scripts are referred to as EEM Policies and can be programmed using a simpleCLI-based interface or using a scripting language called Tool Command Language (TCL). EEM allows customers to harness the significant intelligence within Cisco IOS Softwareto respond to real-time events, automate [...]

Few days ago, Cisco announced the results of the latest Internet Routing in Space (IRIS) testing, marking the first-ever software upgrade of an Internet Protocol (IP) router aboard a commercial satellite while in orbit.

Cisco’s IRIS technology will let you make a VoIP call over the satellite  – and here’s the kicker – without using any terrestrial infrastructure to route the call. That’s a radical departure from current communications satellite technology, which relies on ground-based [...]

Often in a network environment, it is needed to manage a router/switch via console, but what can you do if you don’t have a computer with a serial interface? You can use another router! It is easy to do it. 1) Connect the console interface of the router/switch to the router aux interface using a rollover cable. Rollover cables essentially have one end of the cable wired exactly opposite from the other. As you can see below, this essentially “rolls over” the wires.
