Selecting the Link Layer Protocol

"
3162-A2-GB20-40
Two link layer protocols, Point-to-Point Protocol (PPP) and Serial Line Internet
Protocol (SLIP), are supported for connection to an external SNMP manager,
Telnet device, or network device (e.g., a router). PPP can be used for
synchronous or asynchronous operation. SLIP can be used for asynchronous
operation only.
The DSU/CSU implementation of PPP supports the following:
H
Full negotiation of PPP's Link Control Protocol (LCP).
H
Active negotiation of LCP when the connection is established.
H
Maximum Request Unit (MRU) sizes up to 1500 bytes, but the DSU/CSU will
attempt to negotiate down to 500 bytes.
H
The DSU/CSU provides a unique LCP magic number derived from the unit
serial number and the elapsed time.
H
Full negotiation of escape characters.
The DSU/CSU implementation of PPP does not support Link Quality Reports
(LQR), compression, encryption, Password Authentication Protocol (PAP) or
Challenge Handshake Authentication Protocol (CHAP).
The DSU/CSU implementation of SLIP supports a fixed MRU size of 1006 bytes.
