High-Performance Space-Constrained Branch-Office Switching with Enterprise-Grade Features

Product Overview

The Cisco® Catalyst® 4928 10 Gigabit Ethernet Switch (4928-10GE) is a wire-speed, Layer 2 to 4, 1-rack-unit (1RU) switch designed for space-constrained LAN distribution and core applications. Based on the proven Cisco Catalyst 4500 Series hardware and software architecture, 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 28 wire-speed 1000BASE-X Small Form-Factor pluggable (SFP) ports and 2 wire-speed 10 Gigabit Ethernet (X2 optics) ports. Exceptional reliability and serviceability are delivered with optional internal AC or DC 1 + 1 hot-swappable power supplies and a hot-swappable fan tray with redundant fans (Figure 1).

Figure 1.      Cisco Catalyst 4928 10 Gigabit Ethernet Switch with Hot-Swappable Fan Tray and Power Supplies    


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.

Figure 2.      Branch Office Network Design

The 28-port downlink density is ideally suited for branch-office locations where a collapsed distribution core is the most common network architecture (Figure 2). The downlink ports provide both an aggregation point for all access switches and connectivity and policy services for traffic flows. The uplink ports connect the LAN to the external networks, including remote data centers and branch offices. The SFP downlink ports are compatible with many different optics types, allowing network architects to mix and match to meet specific network requirements.

Key Features and Benefits

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. When the system is in Remote Monitoring (RMON) mode, the management port operates in a disaster-recovery mode. In this state the operator can reload new Cisco IOS® Software images from a TFTP server. 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. With CiscoWorks solutions and embedded CiscoWorks CiscoView, you can configure the switch to manage devices, VLANs, traffic, and policies. These web-based management tools offer numerous services, including software deployment and quick isolation of error conditions.
