Introduction BACS overview BACS is an integrated utility that provides useful information about each network adapter installed in a system. BACS provides views of property values and traffic statistics for network objects. BACS also enables modification of property values. BASP functionality configures VLANs and runs within BACS systems that use at least one Broadcom-based network adapter. Starting BACS From the Control Panel, click Broadcom Control Suite 4 to start the BACS.
• Greyed out device icons indicate the device is currently disabled. Context View selector The Context View selector appears below the menu bar and includes the filter and tab categories. Expand or collapse the categories that appear on the tabs in the Context View pane. To display a category, select the box next to the category name. Filter view A multiple host environment using different adapters with many manageable elements can be difficult to view, configure, and manage.
• Status Bar displays/hides the status bar. • Broadcom Logo displays/hides the logo on BACS to optimize the maximum viewable space. Tools menu Options configure BACS preferences. iSCSI menu • Discovery Wizard locates targets and helps to configure the HBA. • Manage Targets Wizard manages targets. • Manage iSNS Servers manages iSNS servers to allow discovery, management, and configuration of iSCSI devices. • Manage Discovery Portals manages iSCSI discovery portals.
Configuration Configuring preferences When the BACS program is installed, an icon in the Windows taskbar appears. Use the Options window to turn this icon on or off. Enabling or disabling the BACS tray icon 1. From the Tools menu, select Options. 2. Select or clear Enable BACSTray (enabled by default). 3. Click OK. Setting Explorer View refresh time 1. From the Tools menu, select Options. 2. Select Auto to set the Explorer View refresh time to 5 seconds.
6. Type the User name and Password. 7. Select Persist to save the information for this host. The host appears in the Explorer Pane the next time you open BACS, and you do not need to enter the host IP address or host name when connecting to the host. For security reasons, you must enter the User name and Password. 8. Click OK. Managing the host At the host level, you can view host information and configure parameters from the Information and Configuration tabs.
Viewing adapter information Select the network adapter in the Explorer View pane, and then select the Information tab to view adapter-level information. Viewing resource information You can view information about connections and other essential functions for the selected network adapter from the Resources section of the Information tab. The available information depends on the network adapter. • Bus Type is the type of input/output (I/O) interconnect used by the adapter.
• Management Firmware indicates the version installed on the system. • Vendor ID indicates the vendor ID. • Device ID indicates the adapter ID. • Subsystem Vendor ID indicates the subsystem vendor ID. • Subsystem ID indicates the subsystem ID. • External PHY Firmware Version indicates the external PHY firmware version. Configuring adapter parameters Select the network adapter in the Explorer View pane, and then select the Configuration tab to configure adapter-level parameters.
1. Select the Ethernet controller in the object explorer. 2. Select PortX (where X is either 0 or 1) below the adapter in the object explorer. Various components of the port are displayed below the port in the object explorer. 3. Click the plus sign icon next to the port to expand or collapse the tree below. 4. Select Information tab in the Context View Panel on the right side.
o LSO prevents an upper level protocol such as TCP from breaking a large data packet into a series of smaller packets with headers appended to them. o CO allows the TCP/IP/UDP checksums for send and receive traffic to be calculated by the adapter hardware rather than by the host CPU. • LiveLink IP Address is the network address of the LiveLink enabled adapter. • Local Connection identifies the module to which the blade server is attached. • o Chassis SW is the chassis switch module.
• MAC Address is the physical media access control address that is assigned to the adapter by the manufacturer. The physical address is never all 0s. • Permanent MAC Address is the unique hardware address assigned to the network adapter. • Offload Capabilities are capabilities supported by the adapter. This information is only available for certain adapters.
• Frames Rx OK is a count of the frames that were successfully received. This does not include frames received with frame-too-long, frame check sequence (FCS), length, or alignment errors, nor frames lost due to internal MAC sublayer errors. This counter is incremented when the receive status is reported as Receive OK. • Directed Frames Tx is a count of directed data frames that were successfully transmitted.
• Session format error is the number of sessions with errors due to inconsistent fields, reserved fields that are not 0, non-existent LUNs, and so forth. • Sessions failed is the number of failed sessions. Custom statistics Total Offload iSCSI Connections is the total number of offloaded iSCSI connections. Session Statistics The statistics in this area only pertain to the named session. • Session Name is the name used for the session between the initiator and the target.
• MAC Rx w/ no Pause Command enables MAC control frames with no pause command. • MAC Sent X-on indicates that MAC Transmit with X-on is on. • MAC Sent X-off indicates that MAC Transmit with X-on is off. • Large Send Offload Transmit Requests is the number of times the adapter was requested to transmit a packet performing TCP segmentation. • Total Offload TCP Connections is the total number of offloaded TCP connections. • SR-IOV Switch Statistics shows the statistics for SR-IOV switches.
To set the IP address of the iSCSI HBA for iSCSI offload: 1. Click the name of the iSCSI device in the SCSI controller section of the Explorer View pane. 2. To set the IP address, do one of the following: o For IPv4 DHCP and IPv6 DHCP protocols, select Enable to set the IP address dynamically using a DHCP server (not available for iSCSI booted adapters). o For other protocols, select Disable to set the IP address using a static IP address. 3.
CLI commands Configuring with the CLI utility An alternate method to BACS for configuring network adapters is BACSCLI, a utility that enables you to view information and configure network adapters using a console in either a non-interactive command line interface (CLI) mode or an interactive mode. BACSCLI provides information about each network adapter and enables modification of property values. For a complete list of commands and examples, see the BACSCLI ReadMe text file available with the installation.
