The Cisco SD2005 5-port 10/100/1000 Gigabit switch provides nonblocking, wire-speed switching for your 10-, 100-, & 1000-megabit network clients. Use this switch to replace your current workgroup hub or switch, & you can upgrade your high-requirement workstations to full Gigabit speeds as necessary, while continuing to service other clients at their current speeds. Or build your network from the ground up, with appropriate link speeds for each users requirements. Either way, its perfect for graphics, multimedia, & other applications that have to move large files across the network quickly. With the Cisco SD2005, you can connect your existing 10/100 Ethernet network to a Gigabit server backbone without any additional equipment. All ports have automatic medium dependent interface (MDI) & MDI crossover (MDI-X) detection, so you dont have to worry about the cable type. Each port independently & automatically negotiates for best speed & whether to run in half- or full-duplex mode. Address learning & aging is supported, as well as 802.3x flow control with head-of-line blocking prevention to keep your high-speed clients from bogging down in lower-speed traffic. Fast store-&-forward switching prevents damaged packets from being passed on to the network. World-famous Cisco reliability gives you peace of mind, & the ultra-compact case design is sure to fit into your workgroup environment. Let the Cisco SD2005 5-port 10/100/1000 Gigabit switch kick your network into high gear. Please note: networking components such as switches, routers & wireless devices require that speeds & standards be consistent throughout the network to gain optimum performance.

Linksys Service Provider (SPS) switches deliver cost-effective Metro Ethernet Access solutions. These products are optimized for Multi-tenant Units (MTU) & Multi-Dwelling Units (MDU) where Triple Play (Vo IP, Video, & Data) services are delivered by the service provider to multiple businesses or homes in close proximity. The Linksys SPS208G Managed switch, with its combination of intelligence & small size, make it ideal for space-constrained environments where security & uptime are important. It offers a gigabit copper or pluggable SFP module for optional optical interface for connecting to the core network. The SPS switches facilitate the delivery of multiple services over a layer 2 network with support for Q-in-Q. This allows customer VLANs to be kept separate across the service provider backbone. Also, for efficient delivery of multicast traffic (like video) to multiple customers, these switches provide support for a variation of MVR (Multicast VLAN Registration). Network security is a primary concern for service providers, & the SPS family of switches delivers a number of advanced features that alleviates this concern. Support for Dynamic ARP Inspection eliminates the man-in-the-middle attack. IP Source Guard prevents a subscriber (or malicious user) from using an IP address not assigned to them. DHCP Guard eliminates rogue devices from behaving as a DHCP server. STP Root Guard prevents a rogue spanning tree device from advertising that it should be the root bridge thereby having the Spanning Tree network compromised by an outside device. Unauthorized access to the network is protected through 802.1X port & multi-session authentication & MAC Filtering / Port Security. 802.1X requires client to authenticate themselves before the port will pass data. An additional security feature is Access Control Lists (ACLs) which restrict network use to certain users, groups, or applications. Also, the SPS switches secure Management traffic with support for SSH, SSL, & SNMPv 3. The Management capabilities of the SPS switches include support for DHCP option 82, allowing for assignment of IP addresses to subscribers on the basis of where they connect to the network. Configuration of the switches can be performed through a Graphical User Interface or through a Command Line Interface (CLI). The switches also support SNMP for management from a Network Management station. Please note: networking components such as switches, routers & wireless devices require that speeds & standards be consistent throughout the network to gain optimum performance.
