Notice that the sixth line lists encapsulation as PPP, and the seventh line
tells us that LCP is open. Remember that LCP's job is to build and maintain
connections. The ninth line tells us that IPCP, CDPCP, and ATCP are open.
This shows the IP, CDP, and AppleTalk support from NCP. The eighth line
reports that we are listening for IPXCP.
You can verify the PPP authentication configuration by using the debug ppp
authentication
command.
