CHAPTER 8 DATA-LINK PROTOCOLS (ENCAPSULATION)

Each encapsulation option is presented in a separate section in this chapter. Not all data-link protocols are available for all interfaces.

PPP (The Point-to-Point Protocol)

PPPis the only encapsulation option than can be either synchronous or asynchronous. It is important to choose between them in CONFIG =>INTERFACE =><LINK> =>PHYSICAL before entering the Encapsulation menu. The menu options depend on this choice. (Note: not all interfaces support both the synchronous and asynchronous modes. In this case, there is no physical menu.)

The configuration of the PPP data-link protocol is confined to one menu, CONFIG =>INTERFACE =><LINK> =>ENCAPSULATION =>PPP. Information about all the parameters appearing in this menu is provided in the table below. Not all parameters will appear for all interfaces.

PPP Menu CONFIG =>INTERFACE =><LINK> =>ENCAPSULATION =>PPP

Parameter	Description
MLPPP	Enables Multilink PPP on this interface. MLPPP is described in the CyROS
	Reference Guide for each interface that supports it.
Leased, Dial-in, etc.	Applies for MLPPP = Yes. Type of line used on this link.
Identification for This Bundle	Applies for MLPPP = Yes and Dial-outor Leased. An integer value.
Total Number of lines for	Applies for MLPPP = Yes. Maximum number of links allowed in the bundle.
This Bundle
PPP Inactivity Timeout	Applies to asynchronous connections only. The connection is closed when data
	does not pass through the line for this period of time.
Enable Van Jacobson IP	Allows the link to receive compressed packets. This type of compression is
Header Compression	useful for low-speed links and/or small packets. It is not recommended for fast
	links, as it requires CPU time.
Transmit Compressed	Applies when Enable Van Jacobson IP Header Compression is Yes. This
Packets	parameter causes the link to send compressed packets.
