MODEL- DES-3550           VENDOR- D-LINK
   
FEATURES- DES3550-DLINK - Stackable 48-port Switch
       Managed stackable layer 2 switch with (48) 10/100Base-T ports, plus 
        (2) 10/100/1000 Copper/SFP ports.
       D-Link s DES-3550 is a high-performance, managed, stackable Layer 2 
        switch that provides an ideal solution for workgroups and 
        departments. The D-Link Single IP Management (SIM) allows to 
        cluster up a virtual stack of up to 32 DES-3526 and/or DES-3550 
        dispersed switches with fewer distance limitation through a single 
        IP address. The clustering environment spans buildings, making it 
        perfect for business that requires multiple building deployment. 
        The (48) 10/100Mbps Fast Ethernet ports allow desktops to access 
        network resources through flexible 2 Gig uplinks. The entire 
        virtual stack can be managed via a single IP address for simplified 
        network administration.
       Utilizing an 13.6Gbps switch capacity and support for 8,000 MAC 
        addresses, the DES-3550 Stackable Layer 2 Switch is a wire-speed, 
        high performance switch ideal for workgroups or departments. The 
        DES-3550 supports port trunking with up to 6 trunk groups with 2 to 
        8 ports in each group per stack. Port trunking enables business 
        users to increase availability and aggregated bandwidth between 
        servers and/or other switches, optimizing the transport of business 
        critical data. The DES-3550 can utilize either the 10/100Mbps or 
        the 1 Gbps port to cluster up to 32 units within a D-Link SIM 
        stack.
       By widely supporting IEEE approved specifications, the DES-3550 
        Stackable Layer 2 Switch leverages your existing investment in a 
        multi-vendor environment, while maximizing compatibility of mission 
        critical features such as, Spanning Tree (802.1d), QoS (802.1p/
        DiffServ/TCP&UDP port number), VLANs (802.1Q), and network 
        management (SNMP/RMON/BOOTP/Telnet/Web).
       The DES-3550 s robust support of standards-based network management 
        protocols (SNMP/RMON/BOOTP/ Telnet/Web/TFTP) and port mirroring 
        enables the DES-3550 to be easily integrated into many third-party 
        network management packages.
       The DES-3550 Stackable Layer 2 Switch brings advanced enterprise 
        functions to a more affordable level while supporting advanced 
        features: D-Link Single IP Mangement, Dual Images, L2/L3/L4 (QoS), 
        802.1x (Port-based Authentication), 802.1x (MAC-based 
        Authentication) IGMP snooping, 802.1w (Rapid Spanning Tree), 802.1s 
        (Multiple Spanning Tree group), 802.3ad (Link Aggregation), and 
        802.1q (VLANs). L2/L3/L4 (ACLs) can be configured based on: 
        Protocol type, 802.1p, DSCP, MAC Address, IP Address, and/or 
        TCP/UPD Port Number. These features facilitate the deployment of 
        enterprise applications such as: VOIP, streaming media, and 
        multicast content delivery (IP video conferencing and software 
        deployment).
