Key Benefits
®
XRN Technology
Prioritize Business Critical Traffic
3Com XRN™ (eXpandable Resilient
Networking) technology allows
implementation of high availability
configurations using two interconnected
3Com SuperStack 3 Switch 4900s or
Switch 4900 SXs, scaling the backbone
to 24 wirespeed Gigabit Layer 3
switching ports.
Advanced Class of Service support
including support for four queues per
port, 802.1p, and multilayer packet
classification capabilities to allow
prioritization of critical traffic.

Wirespeed, non-blocking Gigabit Ethernet
switching across all ports delivers maximum performance for heavily utilized
networks. The use of XRN Technology
Layer 3 switching capabilities such as
support for IP unicast routing using
static routes, OSPF*, RIP/RIPv2, CIDR,
and UDP Helper, enhance performance, provide network control and
security, and enable logical network segmentation.
intelligent forwarding can scale the
performance of two units to 48 Gbps.
