Extreme Networks 15020 48-Port 1000Mbps Ethernet Switch

Product Description

The Summit48 provides 10/100 Mbps aggregation in service provider data centers, server farms, metropolitan area networks, multi-tenant buildings, and wiring closets. It integrates seamlessly into networks while delivering high port density, wire-speed performance and low cost of ownership.With 48 switched 10/100 Mbps auto-negotiating Ethernet ports and two full-duplex GBIC-based 1000Base-SX, LX or LX-70 Gigabit Ethernet ports, Summit48 has a 17.5 Gbps non-blocking switch fabric and a forwarding rate of 10.1 million packets per second. Summit48 comes with wire-speed Layer 2 and wire-speed basic Layer 3 switching using static routing or RIP V1/V2 routing protocols. For easy scalability, the Summit48 upgrades to full Layer 3 switching with a simple upgrade key. The full Layer 3 switching includes support for protocols such as OSPF, DVMRP, PIM and IPX routing of multiple encapsulation types.

MODEL- SRW2048 VENDOR- LINKSYS FEATURES- 48-Port 10/100/1000 Gigabit Switch with WebView 48-port 10/100/1000 + 4 shared mini-Gigabit Switch with WebView! The Linksys WebView Managed switch allows you to expand your network securely. Configuration of the switch is secured using SSL for Web access and SSH for Telnet access. User control is secured using 802.1x security using a RADIUS authentication mechanism and can also be controlled using MAC filtering. Extensive QoS features makes the solution ideal for real-time applications like Voice and Video. The 4 priority queues together with the Weighted Round Robin and Strict Priority scheduling techniques facilitate efficient co-existence of real-time traffic with data traffic allowing them each to meet their QoS needs. Individual users or applications can be prioritized above others using various Class of Service options - by port layer 2 priority (802.1p) Layer 3 priority (TOS or DSCP) or IPv6 Traffic Class. Intelligent Broadcast Multicast and Unknown Unicast storm control minimizes and contain the effect of these types of traffic on regular traffic. IGMP Snooping limits bandwidth-intensive video traffic to only the requestors without flooding to all users. Incoming traffic can be policed and outgoing traffic can be shaped allowing you to control network access and traffic flow. There are features that allow you to expand and grow your network of switches. Link aggregation allow multiple high-bandwidth trunks between switches to be setup. This also provides a level of reliability in that the system continues to operate if one of the links break. Spanning Tree (STP) Fast Spanning Tree and Multiple Spanning Tree allow you to build a mesh of switches increasing the availibility of the system.
