The list of features below highlights the significant features of the xStack
®
 DGS-3400 Series. 
•  IEEE 802.3z compliant 
•  IEEE 802.3x Flow Control in full-duplex compliant 
•  IEEE 802.3u compliant 
•  IEEE 802.3ab compliant 
•  IEEE 802.3ae compliant (for optional XFP module) 
•  IEEE 802.1p Priority Queues 
•  IEEE 802.3ad Link Aggregation Control Protocol support. 
•  IEEE 802.1X Port-based and MAC-based Access Control 
•  IEEE 802.1Q VLAN 
•  IEEE 802.1D Spanning Tree, IEEE 802.1W Rapid Spanning Tree and IEEE 802.1s Multiple Spanning Tree support 
•  IEEE 802.3af Power-over-Ethernet support for the DGS-3426P 
•  Stacking support in either Duplex-Ring or Duplex-Chain topology 
•  Access Control List (ACL) support 
•  IP Multinetting support 
•  Protocol VLAN support 
•  Single IP Management support 
•  Access Authentication Control utilizing TACACS, XTACACS, TACACS+ and RADIUS protocols 
•  Dual Image Firmware 
•  Simple Network Time Protocol support 
•  MAC Notification support 
•  System and Port Utilization support 
•  System Log Support 
•  High performance switching engine performs forwarding and filtering at full wire speed up to 128Gbps. 
•  Full- and half-duplex for all gigabit ports. Full duplex allows the switch port to simultaneously transmit and receive data. It 
only works with connections to full-duplex-capable end stations and switches. Connections to a hub must take place at half-
duplex. 
•  Support broadcast storm filtering 
•  Non-blocking store and forward switching scheme capability to support rate adaptation and protocol conversion 
•  Supports by-port Egress/Ingress rate control 
•
  Efficient self-learning and address recognition mechanism enables forwarding rate at wire speed 
•  Support port-based enable and disable  
•  Address table: Supports up to 8K MAC addresses per device 
•  Supports a packet buffer of up to 3 Mbits 
•  Port Trunking with flexible load distribution and fail-over function 
•  IGMP Snooping support 
•  MLD Snooping support (MLD v1 and v2) 
•  SNMP support
