Introduction to the Cisco IGX 8400 Series
This guide describes the IGX hardware that runs Release 9.3.30 or later of the Cisco WAN Switching
System Software (switch software) and provides instructions for provisioning services across networks
containing an IGX node. The descriptions cover both common and unique aspects of the
Cisco IGX 8410, 8420, and 8430 models.
For a description of how to install and start an IGX switch, refer to the Cisco IGX 8400 Series
Installation Guide.
For information about the BPX, see Chapter 1, “The BPX Switch: Functional Overview,” in the
Cisco BPX 8600 Series Installation and Configuration guide.
Features of the IGX 8400 Series
Like other Cisco switches, the IGX node operates in public or private wide-area networks (WANs). An
IGX node can support OC3, T3, E3, T1, E1, ATM standards-based inverse multiplexing (also known as
IMA) for T1 or E1, fractional T1 or E1, or subrate digital transmission facilities. The IGX cell relay
technology provides maximum throughput with minimum delays. Cell relay performance characteristics
are the heart of efficient digital networks and make the IGX node an ideal choice for a high-performance,
multimedia platform. Key features of the IGX switch include:
• A 1 gigabit per second (Gbps) cellbus for high-speed switching and a redundant 0.2 Gbps bus for
backup.
• Full compatibility with Cisco BPX 8600 series system software.
• Up to 64 lines, 32 trunks, and 3500 connections on the Cisco IGX 8420 and Cisco IGX 8430
models.
• IGX configuration and management through Cisco WAN Manager or the switch software
command-line interface (CLI).
• High performance switching suitable for a variety of protocols/applications, including
Asynchronous Transfer Mode (ATM), Frame Relay (FR), voice, fax, slow-scan and full-bandwidth
video, and synchronous or asynchronous data.
• Six cabinet models, which consist of:
– An 8-slot standalone unit
– An 8-slot rack-mount unit
– A 16-slot standalone unit
– A 16-slot rack-mount unit
