Figure 64. Inspecting the LAG Status Using the show lacp command
The point-to-point protocol (PPP) is a connection-oriented protocol that enables layer two links over
various different physical layer connections. It is supported on both synchronous and asynchronous lines,
and can operate in Half-Duplex or Full-Duplex mode. It was designed to carry IP traffic but is general
enough to allow any type of network layer datagram to be sent over a PPP connection. As its name
implies, it is for point-to-point connections between exactly two devices, and assumes that frames are
sent and received in the same order.
