WAN Protocols
This device supports the following WAN protocols over the WAN port:
• Point-to-Point Compression Control Protocol (CCP) as defined by RFC 1962
• Point-to-Point Protocol (LCP) as defined by RFC 1661
• Point-to-Point Protocol (BNCP) as defined by RFC 1638
• Point-to-Point Protocol (IPCP) as defined by RFC 1473
• Point-to-Point Protocol (IPXCP) as defined by RFC 1552
• Frame Relay as defined by RFC 1490
• Frame Relay Data Compression Protocol (DCP) as defined by FRF.9
• Inverse Multiplexing (IMUX)
• Dynamic Host Configuration Protocol (DHCP) as defined by RFC 1541
• Network Address Translation (NAT) routing as defined by RFC 1631
• Password Authentication Protocol (PAP) and Challenge Handshake Authentication Protocol
(CHAP) under PPP as defined by RFC 1994
• Point-to-Point Protocol Link Quality Monitoring (LQM) as defined by RFC 1333
• Frame Relay Link Management Interface (LMI) as defined by ANSI T1.617 Annex D and ITU
Q.933 Annex A
• Frame Relay Data Encapsulation as defined by RFC 1490
• Frame Relay Data Compression Protocol (DCP) as defined by FRF.9
PPP is a data link layer industry standard WAN protocol for transferring multi-protocol data traffic
over point-to-point connections. With this protocol, options such as security, data compression,
and network protocols can be negotiated over the connection.
Frame Relay is a packet-switching data communications protocol that statistically multiplexes
many data conversations over a single transmission link. Data Compression (DCP) allows Frame
Relay to negotiate compression over Frame Relay permanent virtual circuits (PVCs).
