Advanced Features
Wake On LAN
This Wake-on-LAN function can wake up the system from the sleeping mode to the fully powered
mode over the network immediately and automatically. Once the system is awake, it can be
directed to run management utilities. This function increases end-user productivity by avoiding
disruptions during working hours.
QoS
The QoS function allows the DGE-530T to transmit and receive tagged frames, such as 802.1p
priority tagged frames and 802.1Q VLAN tagged frames. In order for QoS to function on the DGE-
530T, it must be connected to a switch that supports and is configured for QoS. These priority
tagged frames will let real-time programs optimally utilize the network bandwidth. High priority
packets will be processed before low priority packets.
Jumbo Frames
Jumbo Frames are Ethernet frames that are larger than 1518 bytes. Jumbo frames may be used
to reduce server CPU utilization and improve wire efficiency.
By implementing extra data in fewer packets, jumbo frames can increase throughput and
decrease CPU utilization. However, additional latency may be introduced.
End-to-end network hardware must support this capability or these packets will be dropped.
Consult your network administrator or switch manual for more information concerning
configuring and understanding Jumbo Frames.
•
Supported protocols are limited to IP (TCP, UDP).
•
Jumbo frames require compatible switch connections that forward jumbo frames.
Contact your switch vendor or manual for additional information.
•
There is no benefit to configure jumbo frames if standard size Ethernet frames (64
to1518 bytes) are used.
•
Jumbo frames may be simultaneously used with VLANs.
NOTE: To implement QoS on the DGE-530T, it must be connected to a
switch or other device that supports and is configured for 802.1p QoS.
NOTE: Jumbo frames settings on a switch must be set to 8 bytes or larger
than the adapter settings for Windows operating systems, and at least 22
bytes larger for all other operating systems.
