Interface Flexibility (I-Flex) design combines shared port adapters (SPAs) and SPA interface processors (SIPs), taking advantage of
an extensible design that helps enable service prioritization for voice, video, and data services. Enterprise and service provider customers can
take advantage of improved slot economics resulting from modular port adapters that are interchangeable across Cisco Systems

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 8-port Fast Ethernet SPA (refer to Figure 1).

Product Overview
The Cisco 8-port FE SPA is available on high-end Cisco routing platforms offering the benefits of network scalability with lower initial costs
and ease of 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 for interconnecting routers or other devices within a central office or data center or in a
metropolitan-area network (MAN). With 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 multiple applications, including:
•
Inter- and intrapoint of presence (POP) aggregation
•
Metro Ethernet
•
Internet peering
