FEATURES- TigerStack II 10/100/1000
       Stackable 24-Port 10/100/1000 managed switch with 4 Gigabit combo 
        ports and 2 optional 10G uplinks.
       SMC Networks' TigerStack II 10/100/1000 Switches are the newest in a
        series of "Next Generation" high performance stackable switches 
        that deliver high scalability, wire-speed Gigabit performance, high 
        availability, 10 Gigabit Ethernet uplinks, and redundant power 
        options. These switches are the first to include both IPv4 and IPv6 
        Management options enabling future proofed flexibility and 
        maintainability.
       The TigerStack II 10/100/1000 1000 SMC8824M/SMC8848M stacks up to 
        8 units in a stack, providing up to 384 Gigabit ports. A stack can
        be created with either of the 24 or 48 port switches, providing
        unprecedented flexibility. It provides up to 48 built-in copper 
        Gigabit ports, including (4) Combo SFP ports supporting either 
        copper links or SFP adapters for easy, flexible connection to 
        fiber-based Gigabit media and a switching capacity of up to 
        176Gbps. The two 10G module slots on the rear of the switch provide 
        support for XFP 10G connections. These provide high bandwidth 
        connections to the core of a network and are in additon to the two
        stacking connectors giving high capacity connections to the other 
        units in the stack.
       The SMC8824M/SMC8848M switches feature a variety of network 
        management options for both IPv4 and IPv6: console CLI, telnet, 
        web, SNMPv1/v2/v3, RMON, TFTP, Port Mirroring, BootP, and DHCP. It 
        also supports a variety of advanced traffic management options 
        including: 802.1x, Bandwidth Control, Broadcast Storm Control, and 
        support for IGMP Snooping v1/v2.
       The SMC8824M/SMC8848M provides a robust and consistent set of
        QoS/CoS, VLAN, and security features. It supports 8 priority queues 
        for 802.1p/ToS/DiffServ, with classification and marking based on 
        MAC SA/DA, IP SA/DA, and/or TCP/UDP. Security features include: 
        802.1x (Port Authentication), port security, and Access Control 
        Lists (ACL) based on MAC address, IP address, and/or TCP/UDP port 
        numbers. It also provides extensive support for GVRP, 802.1q, and a 
        flexible VLAN implementation including port, tagged and protocol 
        based VLANs. The SMC8824M/SMC8848M is the latest example of SMC's 
        continued commitment to our channel partners and customers to be 
        the industry leader in cost-effective, reliable, high performance, 
        feature-rich switches.
* High-port density and migration protection in a small footprint
   Supports 24 or 48 10/100/1000Mbps including 2 stacking ports and 2 
   optional 10G uplink slots in a 1RU chassis.
* Advanced Management Support
   Introduces IPv6 Management support to enhance the standard IPv4 
   management interfaces.
* QoS
   Support eight levels of priority, with weighted fair queuing and L2/3/4 
   IP precedence--ensures smooth transmission of mission critical data.
* VLAN with GVRP and 802.1v
   Support VLANs based on frame tags or ports, plus support for automatic 
   GVRP LAN registration spanning tree per VLAN--provides maximum security 
   and bandwidth efficiency.
* IGMP Snooping
   Only allows IP Multicast traffic transmission to the registered members, 
   resulting bandwidth savings--reduce IP multicast traffic and increase 
   LAN performance.
* MultiLink Trunking with LACP
   Can group links between switches to provide higher bandwidth of up to 
   16Gbps.
* Comprehensive security support
   Currently supports RADIUS, IEEE802.1x, SSH, SSL,TACACS+, ACL.
* Redundant Power Supply
   Provides backup power in case of power failure.
