PD1-S21-2281-POE
Features

Excellent Performance:
  • 36 Gbps switch fabric, hardware routing, wirespeed L2 forwarding rate: 9.5 Mpps.
  • 80-km transfer by Gigabit optical fiber, direct connection to WAN.
High security and reliability:
  • IEEE 802.1x and other methods for user authentication.
  • Powerful ACL supports L2-L7 data filtering.
  • QinQ support. Double VLAN security.
Easy maintenance:
  • Automatic recognition for straight-through or crossover cables.
  • Stackable physically and through cluster technology. Central management with unified IP address saves IP addresses.
  • Management via CONSOLE port, Web, SNMP, Telnet, etc.
  • Support (Terrabit Networks) Prodigy Director, HP Open View, Cisco Works 2000.
Traffic and broadcast control:
  • Auto-detection and restraining of broadcast storm, IGMP snooping, effectively restrict broadcast flooding.
  • Full- and half- duplex traffic control.
  • Ethernet port rate limiting with 1 M step size.
  • QoS support.
  • Jumbo frame.
