Cisco 4-Port and 8-Port 10BASE-T/100BASE-TX
Fast Ethernet Shared Port Adapter, V2

The Cisco

I-Flex approach combines shared port adapters (SPAs) and SPA interface

processors (SIPs), providing an extensible design that enables service prioritization for

data, voice, and video services. Enterprise and service provider customers can take

advantage of improved slot economics resulting from modular port adapters that are

interchangeable across Cisco routing platforms. The Cisco I-Flex design maximizes

connectivity options and offers superior service intelligence through programmable

interface processors that deliver line-rate performance. Cisco I-Flex enhances speed-to-

service revenue and provides a rich set of quality-of-service (QoS) features for premium

service delivery while effectively reducing the overall cost of ownership. This data sheet

contains the specifications for the Cisco 4-Port and 8-Port 10BASE-T/100BASE-TX Fast

Ethernet Shared Port Adapters, Version 2 (Cisco Fast Ethernet SPAs; refer to Figure 1).

Product Overview

The Cisco Fast Ethernet SPAs are available on high-end Cisco routing platforms, offering the

benefits of network scalability with lower initial costs and easy upgrades. The Cisco SPA/SIP

portfolio continues the company's focus on investment protection along with consistent feature

support, broad interface availability, and the latest technology. The Cisco SPA/SIP portfolio allows

deployment of different interfaces (packet over SONET/SDH [POS], ATM, Ethernet, etc.) on the

same interface processor.

Fast Ethernet interfaces are commonly used to interconnect routers or other devices within a

central office or data center or in a metropolitan-area network (MAN). With Cisco Fast Ethernet

SPAs, users can mix and match SPA ports with other types of interfaces in the same slot. Each

SPA provides standards-based Fast Ethernet implementation for compatibility and interoperability.

Applications

The Cisco Fast Ethernet SPAs can be used in any combination of the following applications:
