Chapter 2: About the CSX2002-4CSX200 Installation GuideCSX200 Firmware SupportThe CSX200 firmware supports IEEE 802.1d bridging, and IP and IPX routing,. Wide AreaNetworking includes Point-to-Point Protocol (PPP), and Frame Relay. Remote access is via Fullor Fractional T1, E1, Synchronous, Digital Data Service, ISDN, or HDSL connections.This device supports industry-standard protocols, security features, compression algorithms andnetwork management tools to ensure interoperability with equipment from other vendors.IEEE 802.3 EthernetThe CSX200 provides a standard 802.3 Media Access Control (MAC) layer for Ethernetcommunications. All bridging and routing protocols are supported across the Ethernet link.WAN ProtocolsThis device supports the following WAN protocols over the WAN port:• Point-to-Point Compression Control Protocol (CCP) as defined by RFC 1962• Dynamic Host Configuration Protocol (DHCP) as defined by RFC 1541• Network Address Translation (NAT) routing as defined by RFC 1631• 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 1332• Point-to-Point Protocol (IPXCP) as defined by RFC 1552• 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• Point-to-Point Protocol Multilink Protocol (MP) as defined by RFC 1717• Frame Relay Link Management Interface (LMI) as defined by ANSI T1.617 Annex D and ITUQ.933 Annex A• Frame Relay Data Encapsulation as defined by RFC 1490• Frame Relay Data Compression Protocol (DCP) as defined by FRF.9
