3Com 3300 MM SS II Switch 24port 10/100+ Matrix Module |
Overview: The 3C16988 Refurb SuperStack II Switch 3300MM delivers breakthrough pricing for 10/100 Ethernet/Fast Ethernet switching, saving customers up to 50 percent over comparable competitive solutions. The 3300 MM plug-and-play switch has an integrated matrix module links with 3Com®SuperStack® II Switch 1100s and other 3Com® SuperStack® 3 Switch 3300s to create a virtual switch with up to 102 switched ports. Its three matrix or stacking connectors let you stack up to four switches together.. Specifications Total ports: 24 autosensing

Benefits:
Web-based management Security Disconnect Unauthorized Device (DUD) Roving Analysis Port (RAP) RMON support Class of Service (CoS) CoS can be defined simply as a method for prioritizing various traffic types. 3Com switches can support two methods of enabling CoS on Ethernet networks. The first method is IEEE 802.1D (incorporating 802.1p), which enables eight levels of prioritization; and the second method is 3Coms innovative PACE® technology, which allows the user to specify certain applications as high priority. A hardware feature, dual queues, is used to exploit these traffic prioritization schemes; the dual queues functionrequired for CoSwill automatically enable a second port buffer for high-priority traffic thereby allowing the traffic to bypass lower priority data for faster processing within the switch. Traffic Management Flow control Broadcast traffic control Network Availability Backup power supplies Resilient links Spanning tree Port trunking VLANs VLANs allow PCs, workstations, and other resources, including printers and file servers, to be organized into logical, broadcast domains so that only devices within the same domain can communicate with each other. 3Com switches allow users to implement VLANs on their network using one of two schemes: IEEE 802.1Q, including GVRP, which enables the auto-learning of VLANs, or 3Coms VLT. Both methods allow for the configuration of VLANs based on ports and/or MAC addresses for maximum flexibility and security. For 802.1Q VLANs, a port on a switch can be assigned to a VLAN; all other switches learn about that VLAN when the switches automatically communicate that knowledge via the GVRP protocol. Switches supporting both VLAN schemes can be used to provide seamless migration from VLT to IEEE 802.1Q environments that preserve investment in current LAN developments and equipment.
