Using Broadcom Advanced Control Suite 4: Broadcom NetXtreme II Network Adapter User Guide Enables and disables TOE offload when using the IPv4 protocol. The default is Enabled. TCP Connection Offload (IPv6) Enables and disables TOE offload when using the IPv6 protocol. The default is Enabled. Pause on Exhausted Host Ring For BCM57711 and BCM57712 network adapters, there are two possible scenarios that can trigger pause frames to be generated: a host ring buffer is exhausted or the on-chip buffers are depleted. With RSS enabled inside the system, it is possible to achieve better Ethernet throughput if no pause frames are being generated in a case where a host ring buffer (of multiple RSS rings) is exhausted. The default is Disabled. Viewing Resource Information The Resources section of the Information tab displays information about connections and other essential functions for the selected network adapter. NOTE: Some information may not be available for all Broadcom network adapters. Information Tab: Resources Bus Type The type of input/output (I/O) interconnect used by the adapter. Adapters Supporting Remote PHY The following properties are specific to blade servers using a NetXtreme II BCM5708S adapter that supports the Remote PHY feature. Chassis PHY Ethernet@Wirespeed This property is the same as Ethernet@Wirespeed, and is only available when the blade server is attached to a pass-through module. Chassis PHY Flow Control This property is the same as Flow Control, and is only available when the blade server is attached to a pass-through module. Chassis PHY Speed & Duplex This property is the same as Speed & Duplex (excludes 1 Gb Full Auto), and is only available when the blade server is attached to a pass-through module. Chassis SW Flow Control This property is the same as Flow Control, and is only available when the blade server is attached to a switch module. Chassis SW Speed & Duplex This property is the same as Speed & Duplex (SerDes), and is only available when the blade server is attached to a switch module. Configuring System Settings System Management on the Configurations tab allow you to view and change the values of the available properties for the system. The potentially available properties and their respective settings are described below. Chimney Offload State Enables TCP Offload Engine (TOE) for the entire system. On Windows Server 2008 operating systems, the options are Enable (default) and Disable. For Windows Server 2008 R2, the options are Enable, Disable, and Auto (default). If Chimney Offload State is configured for Auto, then a 10 Gbps network adapter will have TOE enabled, but not for a 1 Gbps network adapter. To enable TOE for individual network adapters, configure Chimney Offload State to Enable and also enable TCP Connection Offload (IPv4) or TCP Connection Offload (IPv6) from the Advanced area of the Configuration tab. file:///T|/htdocs/NETWORK/BroadCom/71921/NetXtremeII/en/bacs.htm[9/26/2012 3:29:48 PM]
