In terms of data handling, the WS-X6904-40G-2T implements advanced queuing mechanisms, including Class of Service (CoS) and Differentiated Services Code Point (DSCP) based queue mapping. These mechanisms, along with the Deficit Weighted Round Robin (DWRR) and Weighted Random Early Detection (WRED) schedulers, ensure prioritized data delivery and effective congestion management. The module is also equipped with significant port buffers, featuring 10 MB for ingress and 176 MB for egress, facilitating smooth data flow and reducing packet drops.
Supporting jumbo frames up to 9216 bytes, this module is capable of handling large data packets, improving network efficiency and reducing processing overhead. It is designed to maximize port density within a chassis, allowing up to 32 x 40 Gigabit Ethernet ports or 128 (+2 Supervisor Uplink) 10 Gigabit Ethernet ports in a 6509-E chassis, further extendable in a Virtual Switching System (VSS) configuration.
Compatibility is a key aspect of the WS-X6904-40G-2T, supporting both the Cisco IOS Supervisor Engine 2T and 2TXL. It comes with 2 GB of onboard memory and meets rigorous environmental standards, including various ETSI ETS 300 019 classes for storage, transportation, and stationary use. The module's physical dimensions are 1.2 x 14.4 x 16 inches, and it weighs 12 lbs, making it a compact yet powerful addition to the Catalyst 6500 Series switches.
Operating within a temperature range of 0 °C to 40 °C and a storage temperature range of -40 °C to 75 °C, the module is designed for reliability in various environmental conditions. Its power requirement stands at 468 W, and it features intuitive indicators for status, link, and blue beacon signals, simplifying maintenance and monitoring.
- Supports up to 64 x 40 Gigabit Ethernet ports per VSS in a 6509-E chassis.
- Equipped with advanced queuing and scheduling mechanisms for efficient data handling.
- Designed for compatibility with Cisco Catalyst 6500 Series switches and IOS Supervisor Engine 2T and 2TXL.
