Gigabit Managed Switch UKG2804GM-S(24 electric+4 optic)
Gigabit Managed Switch UKG2804GM-S is a L2/L4 Gigabit managed switch with 2410/100M/1000M RJ45 electrical ports and 4 SFP optical ports. The hardware supports wire-speed switching of the second layer. Users can set the various functions of switches through the Ethernet port by WEB and telnet. Built-in ARP and DOS defense system can effectively defense the ARP, DOS, and a variety of virus attack. It is also equipped with many powerful features: overall ACL, spanning tree, a storm suppression, Bandwidth Control, IGMP Snooping, Port security etc, very suitable for small and medium-sized enterprises, campus network, hotel and MAN tandem application.
Product features:
1. Support four-elements binding IP+MAC+RORT+VLAN, having the higher security;
2. It's unique in the industry with self-defense AUTO-DOS function in the kernel of BCM chip;
3. RJ45 ports of 6000V lightning-enhanced design can effectively extend the life of the product;
4. MSTP:support IEEE 802.1s standard, effectively prevent network loop storm, and downward compatibility to STP, RSTP;5. Storm suppression:set broadcast, multicast and DLF flow rate;6. IGMP Snooping: IGMP version 2 (RFC 2236): IGMP of Snooping is used establishing multicast group to forward the multicast packet when the multicast packet overflow network, avoid wasting bandwidth;7. Powerful ACL access control list, support ACL based on the port, MAC, achieving network monitoring, flow regulation, priority weight markers as well as data forwarding control easily;8. Seasoned security function: AAA certification, 802.1x certification, and defense ARP and DOS attack;
9. Line speed filtration-store-forward mode, providing the true non-blocking switching structure;
Support port mirroring, port aggregation, port speed limit function;
11. UKG2804GM-S of Gigabit SFP ports and electrical port 23, 24 to realize multiplex.
