The Cisco WS-X6848-TX-2T Gigabit Ethernet Interface Module is a high-density line card designed for Cisco Catalyst 6500 and Catalyst 6800 Series modular switches. Featuring 48 auto-sensing 10/100/1000 Gigabit Ethernet RJ-45 ports and an integrated Distributed Forwarding Card 4 (DFC4), it delivers wire-speed Layer 2 and Layer 3 forwarding for enterprise campus, aggregation, distribution, and data center networks.
The module provides 48 Gigabit copper Ethernet interfaces, enabling high-density access connectivity for workstations, servers, IP phones, wireless access points, and other Ethernet-enabled devices. Support for 10/100/1000 Mbps auto-negotiation and Auto MDI/MDIX simplifies deployment across a wide range of network environments.
Equipped with an integrated DFC4 forwarding engine, the WS-X6848-TX-2T performs distributed hardware-based packet forwarding directly on the line card, significantly reducing traffic processing demands on the supervisor engine. This architecture improves overall system scalability while delivering wire-speed Layer 2 and Layer 3 switching with ultra-low latency.
The line card supports advanced enterprise networking features including IEEE 802.1Q VLANs, inter-VLAN routing, IPv4, IPv6, hardware-based Access Control Lists (ACLs), Quality of Service (QoS), multicast, EtherChannel, Link Aggregation (LACP), and jumbo frame support, depending on the installed supervisor engine and Cisco IOS software.
Designed for seamless integration into Cisco Catalyst 6500 and Catalyst 6800 Series chassis, the hot-swappable modular design allows installation and replacement with minimal disruption to network operations. The module is optimized for deployment with Supervisor Engine 2T and compatible Catalyst 6800 supervisor engines, providing enterprise-class performance and high availability.
Ideal for enterprise campus networks, distribution layer switching, data center connectivity, network aggregation, high-density access deployments, and service provider infrastructure, the Cisco WS-X6848-TX-2T 48-Port Gigabit Ethernet Line Card with DFC4 delivers scalable wire-speed performance, advanced hardware forwarding, and reliable connectivity for mission-critical networking environments.
