  • 3Com XRN (eXpandable Resilient Networking) technology allows implementation of high availability configurations using two interconnected SuperStack 3 Switch 4900 family switches, scaling the connections to 48 wirespeed Gigabit Layer 3 switching ports (with purchase of optional 3Com XRN Interconnect Kit, available now, or future GBIC Fabric Interconnect)
  • Advanced Layer 2 and Layer 3 functionality - such as multicast filtering, enhanced QoS/CoS services, virtual LANs, and multilayer traffic classification and prioritization?provides network-wide traffic control
  • 3Com-developed ASIC architecture delivers 56 Gbps multilayer switching capacity per unit, wire-speed performance across all ports, and a forwarding rate of more than 41 million pps
  • Layer 3 switching capabilities - such as IP unicast using static routes, RIP/RIPv2, and CIDR - help enhance performance, provide network control and security, and enable routing between VLANs
  • Support for high availability software features such as Link Aggregation using 802.3.ad, Resilient links, Spanning Tree and Rapid Spanning Tree (802.1w), seven groups of RMON, and e-mail alerts
  • Security features like RADIUS client support and Routed Access Control Lists protect sensitive network information and ensure that users have access to authorized resources
