Adapter Properties
• 802.1p QoS Packet Tagging. Enables or disables IEEE 802.1p tagging to send network traffic with different priority levels.
o Default = Off
o Range = Off; On
• Coalesce Buffers. Specifies the number of memory buffers available to the driver in case the driver runs out of available map registers. This buffer area is also used when a packet consists of many fragments. If no coalesce buffers or map registers are available, the driver is forced to queue the packet for later transmission. The preferred method of transmitting data is to use map registers, since it is the most efficient method.
o Default = 8
o Range = 1–32
• Flow Control Settings. The Flow Control property allows the user to enable or disable the receipt or transmission of PAUSE frames. PAUSE frames enable the adapter and the switch to control the transmit rate. The side that is receiving the PAUSE frame will momentarily stop transmitting. The recommended selection is Off and it is the default setting. To disable Flow Control, select Off from the Value list on the Advanced tab.
o Default = Off
o Range = Off, Generate, Respond, Respond and Generate Off. PAUSE frame receipt and transmission is disabled Generate. PAUSE frame transmission is enabled Respond. PAUSE frame receipt is enabled
