Designed for workgroups and departments, TL-SL5428 from TP-Link provides wire-speed performance and 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 Fast Ethernet switches and high-speed servers in demanding small networks.

 

IP Clustering allows up to 32 TL-SG5426/TL-SL5428 switches to be managed by a single IP, regardless of geographical locations. With all units identified by a single IP address, the stack could be configured, monitored, maintained as a single object.

Tra¬ffic running across units in this virtual stack utilizes full-duplex interfaces and network wires, eliminating costly and cumbersome cables, minimizing the impact of any single point of failure.

Standard management features are included such as SNMP v1/v2c/v3, RMON, intuitive web-based GUI, industry standard Command Line Interface(CLI).

With link aggregation, spanning tree protocol and virtual stack, a highly intelligent and scalable topology could be established, fulfilling the enterprise customers’ requirement of building a unified, resilient network.

Access Control Lists (L2/L3/L4) restrict access to sensitive network resources by denying packets based on source and destination MAC addresses, IP addresses, TCP/UDP ports. This is done by hardware, so switching performance would not be compromised.

Moreover, Dynamic ARP Inspection which protects the network from "man-in-the-middle" attacks, IP Source Guard which prevents IP spoofing attacks such as DoS, together with 802.1x port-based authentication provide robust security to the network.

To integrate voice, data and video service on one network, TL-SG5426 applies rich QoS policies. Administrator can designate the priority of the traffi¬c based on a variety of means including IP or MAC address, TCP or UDP port number, etc, so voice and video are always clear, smooth and jitter free.

For other multimedia-on-demand application such as IPTV, TL-SG5426 provides advanced features for easy stream management. For example, IGMP snooping ensures the switch intelligently forward the multicast stream only to the appropriate subscribers while IGMP throttling & filtering restrict each subscriber on a port level to prevent unauthorized multicast access

+ 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.

+ Multicast snooping automatically prevents flooding of IP multicast traffic.

+ Root Guard protects root bridge from malicious attack or configuration mistakes

+ GVRP (GARP VLAN Registration Protocol) allows automatic learning and dynamic assignment of VLANs.

+ Supports 255 active VLAN groups and 4K VLAN IDs.

+ Q-in-Q increases the network scalability by providing a hierarchical structure.

+ Supports L2/L3/L4 granular CoS 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 and TACACS+ Authentication

+ IP Source Guard prevents IP spoofing attacks such as DoS.

+ Dynamic ARP Inspection blocks ARP broadcasts from unauthorized hosts, preventing "man-in-the-middle" attacks.

+ L2/L3/L4 Access Control Lists restrict untrusted access to the protected resource.

+ IP Clustering provides high scalability and easy Single-IP-Management.

+ Supports Telnet, Cisco Like CLI, SNMP v1/v2c/v3, RMON and web access, which are all secured by SSHv2.

+ Port Mirroring enables monitoring selected ingress/egress traffic.

+ 802.1ab LLDP automated device discovery protocol for easy mapping by NMS
