18-Port GBIC-Enabled Gigabit Ethernet Line Card

(WS-X4418-GB)

The Cisco Catalyst 4000 Series 18-port Gigabit Ethernet line

card provides two ports of dedicated 1000BaseX GBIC-based

Gigabit Ethernet uplinks, as well as up to 16 GBIC-based ports

for high-performance Gigabit Ethernet server connectivity.

The 16 server ports can burst to Gigabit Ethernet line rate and

share 8 Gbps of full-duplex bandwidth into the switching

fabric. Because all ports use GBICs, the amount of

oversubscription can be controlled by varying the number of

GBICs used. All ports can utilize Gigabit EtherChannel for

high-speed interconnection applications. The server ports use

the standard IEEE 802.1x ﬂow control (PAUSE frame)

mechanism to control Gigabit Ethernet host trafﬁc.

Key Benefits

High Performance and Cost-Effective Gigabit Ethernet

Connectivity

Delivering advanced switching solutions that scale bandwidth

as you add ports, the Cisco Catalyst 4000 Series solution is

wire-speed Layer 2 and Layer 3 gigabit switching solutions.

Layer 2 switching is powered by a 24-Gbps, 18-Mpps engine

and Layer 3 switching is powered by a scalable 8-Gbps,

6-Mpps engine. Supporting a very low latency, centralized,

shared-memory switching fabric architecture, the Cisco

Catalyst 4000 Series enables high performance, Gigabit

Ethernet server connectivity and Gigabit Ethernet to the

desktop. By blending advanced engineering and advances in

manufacturing, the Cisco Catalyst 4000 Series delivers

powerful Gigabit Ethernet switching solutions at a very

cost-effective price point.

Functionally Transparent Gigabit Ethernet Line Cards

The Cisco Catalyst 4000 Series architecture enables

customers to easily upgrade all Gigabit Ethernet line cards on

their Catalyst 4000 systems to higher-layer switching

functionality by simply adding new fabric engine modules

such as a new Layer 3 services module. This enables

customers to easily upgrade their networks to deploy new

higher-layer functionality on their Gigabit Ethernet switching

solutions without replacing existing Gigabit Ethernet line

cards.

Scalable and Reliable Gigabit Ethernet Solutions

The modular chassis ﬂexibility, variety of Gigabit Ethernet

modules, and hardware and software redundancy features

ensure that the Cisco Catalyst 4000 Series meets customers’

needs by delivering reliable, fault-tolerant, and scalable

Gigabit switching solutions. Cisco Gigabit EtherChannel

technology, which is based on proven EtherChannel

technology pioneered by Cisco and extensively deployed in

networks worldwide, enables customers to deploy

multigigabit links in server farms that scale up to 8 Gbps ports

for each Gigabit EtherChannel. Port redundancy with

UplinkFast and PortFast, Spanning Tree Algorithm

enhancements, and link redundancy with Gigabit

EtherChannel, across Gigabit links, ensures reliable and

fault-tolerant operations of critical applications.

Gigabit Ethernet Solutions with Proven Cisco Catalyst

Enterprise Software

The Cisco Catalyst 4000 Series Gigabit Ethernet solutions

deliver consistent, high-end enterprise features by supporting

the same software feature set as that of the industry-leading

Cisco Catalyst 2900, 5000, and 6000 Series. With consistent

software and user interfaces, customers can retain their

knowledge base and continue to grow their networks with

Cisco Catalyst 4000 Series Gigabit Ethernet solutions and

interface seamlessly with other Catalyst 2900, 5000, and 6000

Series switches in the network.
