*Automatic self configuration: Using [[Link Control Protocol]] it has to negotiate protocol features like Address-and-Control-Field-Compression (ACFC), escaped characters, and the compression, encryption (like [[Microsoft Point-to-Point Encryption|MPPE]]) and authentication methods to use.

*Access control and authentication: Using protocols like [[Challenge-handshake authentication protocol]] (CHAP) or [[Password authentication protocol]] (PAP) it has to provide and check authentication data.

*Layer 3 configuration: If using [[Internet Protocol Control Protocol]] (IPCP), it will negotiate or determine [[Internet Protocol|IP]] parameters such as the [[IP address]]es, the [[maximum transmission unit]], and [[name server]] addresses. Some versions may also support [[Internetwork Packet Exchange Control Protocol]] (IPXCP) and [[AppleTalk Control Protocol]] (ATCP) for routing [[IPX]] or [[AppletalkAppleTalk]] over the link.

*After negotiation is complete, it has to set up the required network interfaces and routes, so that the connection is run by the [[Kernel (computer science)|kernel]].
