The Cisco WS-X4712-SFP-E Catalyst 4500E 12-Port Gigabit Ethernet SFP Line Card is a high-performance modular interface card designed for Cisco Catalyst 4500E Series switches. It provides 12 nonblocking Gigabit Ethernet SFP ports with support for compatible 1G and 100FX SFP transceivers, delivering flexible fiber connectivity for enterprise campus, distribution, aggregation, and service provider networks. With 12 Gbps per-slot capacity and line-rate forwarding, it provides reliable optical connectivity for bandwidth-intensive network environments.
The WS-X4712-SFP-E integrates with compatible Catalyst 4500E Supervisor Engines and inherits platform-level forwarding and QoS capabilities. It supports Layer 2 through Layer 4 services, VLANs, IPv4/IPv6 networking, jumbo frames up to 9,216 bytes, Cisco TrustSec, and IEEE 802.1AE hardware-based encryption on supported configurations. Compatible with Cisco IOS XE releases such as 3.5.0E and later, the module provides scalable and secure fiber expansion within Catalyst 4500E deployments.
The Cisco WS-X4712-SFP-E is an ideal solution for enterprise campus networks, fiber backbone connectivity, distribution-layer switching, data center aggregation, Metro Ethernet deployments, and service provider access networks. Its modular SFP architecture enables organizations to select appropriate optical transceivers for different fiber types and distances while extending the capabilities of an existing Catalyst 4500E switching infrastructure.
