    • Cisco 4900 Switches, Main Features&Model ComparisonCisco Catalyst 4900 Series Switches deliver high-performance, low-latency wire-speedLayer 2 and 3 services in a small form factor (1 or 2 rack units).The Catalyst 4900 Series is ideal for space-constrained deployments.Data Center: Top-of-Rack Server Aggregation Architectural Flexibility: Increased link use without buffer overflow and Layer 2 and 3 support at the access layer as needed Investment Protection: Smooth transition from 10/100/1000 to 10 Gb Ethernet interfaces Simplified Management: Edge switch auto-provisioning
    • Transport Flexibility: Support for a wide range of storage, high-performance computing, and video applicationsBranch Offices: LAN Collapsed Core and Distribution Aggregation Interface Flexibility: Support for a wide range of Gb Ethernet and 10 Gb Ethernet interfaces High Performance: Up to 320 Gbps forwarding capacity Multilayer Support: Support for main routing protocols and IPv6 in hardware High Availability: Hot swappable redundant power supply and fans Investment Protection: Simple migration from Gb to 10 Gb EthernetNOTE:The latest addition to the Cisco Catalyst 4900 Series is the Cisco Catalyst 4948E.It inherits all the features of the award-winning Catalyst 4948 10Gb Ethernet Switch andalso offers 10Gb Ethernet uplinks, front-to-back airflow, and IPv6 in hardware.The following table compares the features of the Cisco Catalyst4948, 4948 10 GigabitEthernet, 4928 10 Gigabit Ethernet, 4948E, 4948E-F and 4900M Switches.Cisco Catalyst 4900 Series Switches Model Comparison - Hardware FeaturesFeature and Cisco Cisco Cisco Cisco Catalyst CiscoDescription Catalyst Catalyst Catalyst 4900M Catalyst 4948 4948 10 4928 10 4948E
