DATA SHEET CISCO CATALYST 4948-10GE SWITCH 10 Gigabit Ethernet Switching for High-Performance, Rack-Optimized Server Switching PRODUCT OVERVIEW The Cisco® Catalyst® 4948-10GE Switch is a wire-speed, low-latency, Layer 2–4, 1-rack-unit (1-RU), fixed-configuration switch for rack-optimized server switching.
KEY FEATURES AND BENEFITS Wire-Speed Performance in All Directions The Cisco Catalyst 4948-10GE delivers wire-speed throughput with low latency for data-intensive applications using a 136-Gbps switching fabric with a 102 million packets per second (mpps) forwarding rate in hardware for Layer 2–4 traffic. High-performance switching is maintained regardless of the number of route entries or Layer 3 and 4 services enabled.
SOFTWARE CONFIGURATION OPTIONS Table 1 describes the software configuration options for the Cisco Catalyst 4948-10GE. Table 1.
Sharing, shaping, and strict-priority configurations determine scheduling of egress traffic. The Catalyst 4948-10GE also supports Dynamic Buffer Limiting (DBL), a congestion-avoidance feature. For details about the QoS features (including DBL) on the Catalyst 4948-10GE, refer to the QoS on Cisco Catalyst 4500 Series supervisor engines overview at: http://www.cisco.com/en/US/partner/products/hw/switches/ps4324/prod_white_papers_list.
