Cisco Embedded Event Manager (EEM) is a feature included in Cisco's IOS operating system (and some other Cisco OSes such as IOS-XR, IOS-XE, and NX-OS) that allow programmability and automation capabilities inside the device. EEM allows the behavior of a Cisco device to adapt to specific user requirements by allowing scripting, thresholding ...
Earlier, Cisco switches ran CatOS. Cisco IOS is a package of routing, switching, internetworking and telecommunications functions integrated into a multitasking operating system. Although the IOS code base includes a cooperative multitasking kernel, most IOS features have been ported to other kernels such as QNX and Linux for use in Cisco products.
In computer networking, Point-to-Point Protocol (PPP) is a data link layer (layer 2) communication protocol between two routers directly without any host or any other networking in between. [1] It can provide loop detection, authentication, transmission encryption, [2] and data compression.
