Main Features

• Green Energy
  • TR‐S2528D series comply with IEEE 802.3az (Energy‐Efficient Ethernet) standard, dramatically lower power consumption
  • With Innovative port‐LED Shut‐off function, the user can automatically set the switch port‐LED UP or DOWN at a specified time period according to their needs to achieve functional, energy‐ saving correct results.
  • Full account of low noise requirements of the environment, TR‐S2528D uses smart fan strategies to real‐time temperature monitoring system, and reduce the noise pollution.
• Simple and Flexible Operation and Maintenance
  • Full Ethernet OAM technology (IEEE802.3ah/802.1ag), VCT, DDM (Digital Diagnostic Monitoring) and other features achieve rapid detection of the network failures; reduce operation and maintenance difficulty.

• Enhanced Security
  • TR‐S2528D series provide a variety of security mechanisms like SYN Flood, Land, ICMP Flood attack prevention and other DOS class technology, BPDU Guard and Root Guard which avoid accidental topology loops and prevent illegal edge devices become root to cause unnecessary flapping.
  • IEEE 802.1X port‐based access control ensures all users are authorized before being granted access to the network. User authentication is carried out using any standard‐based RADIUS server.
  • Access Control Lists (ACLs) can be used to restrict access to sensitive network resources by denying packets and forward by different policies. User‐defined ACL provides more flexible access control for users.
  • TR‐S2528D series support DHCP snooping, which prevents DHCP attacks and illegal DHCP SERVER by setting trust ports and untrust ports. With DHCP Snooping binding and option82 enabled, it can combine modules like dot1x and ARP, or implement user‐access‐control independently.
  • TR‐S2528D series support much more L2 security features such as ARP guard, Anti‐ARP scanning, and other ARP and MAC Security technology to protect network security and reliability.
• High Reliability
  • TR‐S2528D series support 4 Gigabit uplink ports, which could be designed to offer redundant uplinks with various ring protection applications, effectively raised the expansibility and performance of network.
  • G.8032 provides sub‐50ms  protection  and  recovery  switching  for Ethernet traffic  in  a carrier ring topology. TR‐S2528D series support G.8032 v2 and can be deployed in a variety of complex network topologies including single ring, tangent ring, intersecting rings, double rings and other home networking.
  • Built‐in 4K lightning protection for ports on TR‐S2528D series effectively resists lightning, reduces equipment damage significantly.
• High adaptability VLAN Features
  • TR‐S2528D series support 802.1Q and port based VLAN as well as MAC based VLAN, Voice VLAN and Protocol VLAN.
  • Abundant QinQ technology including Normal QinQ, Selective QinQ, and Flexible QinQ, gives users maximum freedom to configure QinQ policy.
  • N:1 VLAN Translation feature can translate multiple VLAN tags in the frames from access ports into one specified VLAN Tag. It provides a strong technical support for QoS policy convergence.
• Abundant Multicast Features
  • TR‐S2528D series also support MVR (Multicast VLAN Register), selectively allows traffic to cross between different VLANs for bandwidth and security reasons. With MVR Trunk function, which could associate multicast VLAN to trunk port, TR‐S2528D series combines the VLAN data into the same link, saving lots of resources for users.

• • TR‐S2528D series could prevent multicast traffic from flooding via IGMP Snooping, while multicast traffic is only forwarded to ports associated to multicast devices.
