3COM  3Com® SuperStack® 3 Switch 4950 3C17706-US
The 3COM 3C17706-US you're interested in is a: High-performance, flexible-media Gigabit Ethernet switching over copper with optional XRN™ technology support; 24 ports.
Flexible Switching for the Backbone
Deliver
multilayer gigabit switching performance at the backbone with this Gigabit
switch. Supporting both copper and fiber connectivity, this switch provides a
unique combination of high performance and media flexibility for a building or
wiring closet aggregator, as well as for a server farm. This flexible switch
provides six fixed 1000BASE-SX ports, 12 fixed 10/100/1000 copper ports, and six
fixed GBIC ports that can support a combination of 1000BASE-SX, 1000BASE-LX, and
1000BASE-LH70 (long-haul Gigabit Ethernet).
The SuperStack 3 Switch 4950
supports 3Com Gigabit Multilayer Switching software, which offers feature-rich
Layer 2 functionality, Layer 3 switching for IP networks, and advanced traffic
prioritization and security capabilities to accommodate the ever growing
requirements of enterprise networks.
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, or GBIC Fabric Interconnect with GMS Advanced Feature
License)
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 OSPF, IP unicast using static routes,
RIP/RIPv2, and CIDR—help enhance performance, provide network control and
security, and enable routing between VLANs (OSPF available with purchase of GMS
Advanced Feature License, 3C1770v4)
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
Optional 1000BASE-SX, 1000BASE-T, 1000BASE-LX and GBIC-based expansion
modules deliver four ports of high-performance, feature-rich switching over
copper or multimode fiber
3Com® Network Supervisor, (60-day trial version included with the switch),
offers discovery, mapping, monitoring, and alerting for easy network
administration
