The Point-to-Point Protocol over Ethernet (PPPoE) is a network protocol for encapsulating Point-to-Point Protocol (PPP) frames inside Ethernet frames. It appeared in 1999, in the context of the boom of DSL as the solution for tunneling packets over the DSL connection to the ISP's IP network, and from there to the rest of the Internet.
PPP, PPPoE and PPPoA are widely used in WAN lines. PPP is a layered protocol that has three components: [4] An encapsulation component that is used to transmit datagrams over the specified physical layer. A Link Control Protocol (LCP) to establish, configure, and test the link as well as negotiate settings, options and the use of features.
The original PoE standard, IEEE 802.3af-2003, [1] now known as Type 1, provides up to 15.4 W of DC power (minimum 44 V DC and 350 mA) [2] [3] on each port. [4] Only 12.95 W is guaranteed to be available at the powered device as some power dissipates in the cable.

Bootstrap – when device contacts the server for the first time, the server URL changed, or the device settings were reset to default; Periodic – the device is scheduled to perform a periodic session, as per the PeriodicInformInterval settings; Connection request – the device responds to the server's request for a connection;
PPPoX (PPP over X) designates a family of encapsulating communications protocols implementing Point-to-Point Protocol.. Specific implementations: PPPoE: PPP over Ethernet – which can use 802.1q VLANs
CHAP is also used in PPPoE, for authenticating DSL users. As the PPP sends data unencrypted and "in the clear", CHAP is vulnerable to any attacker who can observe the PPP session. An attacker can see the user's name, CHAP challenge, CHAP response, and any other information associated with the PPP session.
