Designed for workgroups & departments, TL-SG5428 from TP-LINK provides full set of layer 2 management features. It delivers maximum throughput where you need it — to high-performance workgroups at the edge of the network, or as a backbone for Gigabit Ethernet switches & high-speed servers in small networks. Moreover, TL-SG5428 switch also comes equipped with 4 SFP slots, giving you greater network flexibility. This TP-LINK L2 managed switch has robust security & management features. An advanced Access Control List (ACL, L2 to L4) & the TP-LINK strong safeguard provide security coverage from core to edge & protect against broadcast storm, ARP & Denial-of-Service (Do S) attacks, etc. Quality of Service (Qo S, L2 to L4) provides enhanced traffic management capabilities to move your data smoother & faster. Anymore, the easy-to-use web management interfaces, along with CLI, SNMP & RMON, mean faster setup & configuration with less downtime. For workgroup & departments requiring cost-sensitive Layer 2 Switch, & additional Gigabit capability, TP-LINK L2 managed Switch TL-SG5428 can provide you the ideal access-edge solution. LLDP serves to reduce the complexities of the network Link aggregation (LACP) increases aggregated bandwidth, optimizing the transport of business critical data IEEE 802.1s Multiple Spanning Tree, provides high link availability in multiple VLAN environments. Support IEEE 802.1d/w/s Spanning Tree (STP/RSTP/MSTP) IGMP snooping allows the forwarding of multicast packets such as streaming audio & video, without increasing network broadcast congestion. Non-blocking Layer 2 Switching Capacity GVRP (GARP VLAN Registration Protocol) allows automatic learning & dynamic assignment of VLANs Supports 4K active VLAN groups & 4K VLAN IDs Q-in-Q increases the network scalability by providing a hierarchical structure Supports 802.1P, Class of Service (Co S) with 4 priority queues per port Rate limiting confines the traffic flow accurately according to the preset value Supports multiple industry standard user authentication methods such as 802.1x, RADIUS Authentication, Supports 400 IP-MAC-Port-VID Binding entries IP Source Guard prevents IP spoofing attacks such as Do S Port Security enhances the security of all ports L2/L3/L4 Access Control Lists restrict untrusted access to the protected resource Virtual stackable provides high scalability & easy Single-IP-Management Supports Telnet, Cisco like CLI, SNMP v 1/v 2/v 3, RMON & web access Supports SSL & SSH encryptions Port Mirroring enables monitoring selected ingress/egress traffic
