The NetVanta® 4430 is an access router designed for higher-bandwidth applications supporting up to eight T1s for Internet access, corporate Frame Relay, point-topoint connectivity, ADSL, VPN, and carrier Ethernet connections.

Modular Hardware

Residing in a 1U high, 19" rackmountable metal enclosure, the NetVanta 4430 is a single platform that offers one wide module slot, two Network Interface Module (NIM) slots, dual Gigabit Ethernet LAN ports (copper or fiber) for true LAN segmentation or DMZ applications, and one 10/100Base-T Fast Ethernet port for management or routing. The single wide module slot within the NetVanta 4430 will house the Octal T1/E1 Wide Module, while the NIM slots will support a variety of the NetVanta NIMs and Dial Backup Modules (DIMs). For dial backup, an analog modem DIM or an ISDN BRI DIM is available for preventing downtime by dialing around a failed circuit to any PPP-compliant device.

Standards Protocols

The versatile hardware platform of the NetVanta 4430 is further complemented with the AOS. The AOS allows for the support of static and default routes, demand and policy-based routing, and allows for fast, accurate network convergence using routing protocols such as BGP, OSPF, RIP, and PIM Sparse Mode for multicast routing. In addition, the AOS terminates MPLS, Frame Relay, Multilink Frame Relay, PPP, Multilink PPP, PPPoE, PPPoA, RFC 1483, and HDLC Wide Area Network (WAN) protocols. Multihoming is also available to provide redundant or backup WAN links to multiple ISPs, guaranteeing a wide-area connection.


QoS is also supported for delay-sensitive traffic like VoIP or video. To prioritize mission-critical traffic and control network congestion, the NetVanta 4430 uses Low Latency Queuing, Weighted Fair Queuing (WFQ), Class-based WFQ, and DiffServ marking to establish priority of IP packets routed over the WAN. The NetVanta 4430 also includes Enhanced QoS support for Ethernet WAN connections including the ability to prioritize traffic by VLAN.

VoIP Ready

In combination with the QoS features, a specialized Session Initiation Protocol (SIP) Application Layer Gateway (ALG) allows SIP traffic to traverse NAT-enabled firewalls. For an enterprise network, this interoperability allows IP PBXs, phones, and other SIP-based devices to set up, tear down, and pass voice and call control messages seamlessly through the integral NAT-enabled firewall. The NetVanta 4430 also supports VQM to capture MOS, jitter, delay, and packet loss statistics necessary to troubleshoot VoIP calls over the WAN. This powerful, yet graphically intuitive, diagnostic tool allows for quick isolation of network issues to ensure superior call quality.


The AOS provides a powerful, high performance stateful inspection firewall that can identify and protect against common Denial of Service (DoS) attacks like TCP syn flooding, IP spoofing, ICMP redirect, ping of death, and IP reassembly problems. In addition, the AOS is capable of providing an inherent URL-filtering package without the use of an external server. URL-filtering is another level of security that allows system administrators to restrict Internet access by permitting or denying specific URLs. This URL filtering feature also includes the ability to produce top website reports of the most frequently requested websites, allowing system administrators to modify the URL filter lists. The NetVanta 4430 also adds the support for IPSeccompliant VPN. The NetVanta 4430 supports up to 1,000 simultaneous VPN tunnels, while also supporting encryption algorithms like DES, 3DES, and AES. With this upgrade, the NetVanta 4430 is fully compatible with other IPSec VPNequipped NetVanta products.


The AOS offers both a CLI that mimics the widely deployed industry de facto standard and an intuitive Web-based GUI with stepby- step configuration wizards.
