C ONFIGURING PPP
Note: A thorough understanding of PPP protocol is required before you attempt to change the
PPP configuration. By changing the PPP configuration, you are changing the PPP protocol
negotiation parameters. These parameters only need to be changed when you are
attempting to interoperate with devices that do not provide a standard PPP
implementation. Changing these parameters can result in PPP option negotiation failure
and the inability to communicate with remote devices. The default parameters are
adequate for most sites.
