This software upgrades a 3Com® SuperStack® 3 Switch 4400 SE 24-Port to the same feature set as a 3Com SuperStack 3 Switch 4400 24-Port, with Quality of Service (QoS) traffic control, edge security, and configuration enhancements.

Advanced multilayer traffic classification, prioritization, and filtering help maintain service levels for real-time applications such as voice over IP (VoIP). User authentication improves network edge security, while the switch configuration backup and restore function saves administrative costs.

• Makes the 3Com SuperStack 3 Switch 4400 SE 24-Port functionally identical to the 3Com SuperStack 3 Switch 4400 24-Port
• Enhanced QoS capabilities—including support for multilayer traffic classification, IEEE 802.1p prioritization, DiffServ marking, and wirespeed application filtering and blocking—optimize the performance of delay-sensitive, real-time applications
• Automatic identification and prioritization for 3Com NBX® Networked Telephony Solution VoIP traffic keeps voice quality high no matter what other applications are running on the network
• Edge security with IEEE 802.1x Network login authenticates all users as they enter the network through the RADIUS (remote access dial-in user service) control protocol server, keeping unauthorized users from accessing network resources and data
• Switch configuration backup and restore eases administration when configuring, replacing, recovering, and moving network devices
• Transparent webcache redirection improves web performance and reduces network administration
