WS-C4928-10GE: Cisco 4900M Switch WS-C4928-10GE, 28-ports, L3- Managed, Rack-mountable 1U, Gigabit Ethernet
The Cisco Catalyst 4928 10 Gigabit Ethernet Switch is a wire-speed, Layer 2 to 4, 1-rack-unit (1RU) switch designed for space-constrained LAN distribution and core applications. This switch offers exceptional performance, bandwidth, and reliability for medium-density, multilayer aggregation of high-performance LAN access switches. High performance and scalability of intelligent network services are made possible with dedicated specialized resources known as ternary content addressable memory (TCAM). Ample TCAM resources (64,000 entries) enable high feature capacity, providing wire-speed routing and switching performance with concurrent provisioning of services such as quality of service (QoS) and security, helping ensure scalability for today’s network requirements with ample room for future growth.
The Cisco Catalyst 4928 10 Gigabit Ethernet Switch offers flexible and highly available aggregation solutions for nonstop unified network services. Enterprise-grade features such as dynamic routing, dual hot-swappable power supplies, and redundant field-replaceable fans enhance switch availability.
The switch is well-suited for space- and power-constrained deployments because of its compact 1RU form factor, economical power needs, and efficient cooling. Ideally suited to support secure converged applications such as Cisco TelePresence and Cisco Unified Communications, the switch delivers high-performance intelligent switching with its robust feature set.
- Wire-speed performance in all directions
The Cisco Catalyst 4928 10 Gigabit Ethernet Switch delivers wire-speed throughput with low latency for data-intensive applications using a 96-Gbps switching fabric with a forwarding rate of 72 million packets per second (mpps) in hardware for Layer 2 to 4 traffic. High-performance switching is maintained regardless of the number of route entries or Layer 3 and 4 services enabled. Hardware-based Cisco Express Forwarding routing architecture enables increased scalability and performance. X2 10 Gigabit Ethernet optics provide 20 Gigabit Ethernet wire-speed uplinks for maximum traffic throughput.
- Power-supply redundancy for nonstop operations
The Cisco Catalyst 4928 10 Gigabit Ethernet Switch provides reliability for critical applications with 1 + 1 redundant, hot-swappable internal AC or DC power supplies. The 1 + 1 power supply design provides A-to-B failover when power supplies are connected to different circuits. You can mix AC and DC power supplies in the same unit for maximum deployment flexibility. The switch also has a hot-swappable fan tray with four redundant fans for additional serviceability and availability.
- Comprehensive management
The Cisco Catalyst 4928 10 Gigabit Ethernet Switch includes a single, dedicated 10/100 console port and a single, dedicated 10/100 management port for offline disaster recovery and remote out-of-band management. Remote in-band management is available with the Simple Network Management Protocol (SNMP), Telnet Client, Bootstrap Protocol (BOOTP), and Trivial File Transfer Protocol (TFTP). The management port has two operating modes designed to increase operational efficiency and availability. During normal system operation the management port operates as a standard out-of-band management port. Network administrators can use standard command-line interface (CLI) commands to monitor and configure the switch without interrupting the data flow. The Cisco Catalyst 4928 10 Gigabit Ethernet Switch delivers a comprehensive set of management tools to provide the visibility and control required for LAN switching. These web-based management tools offer numerous services, including software deployment and quick isolation of error conditions.
