Problem: The BCM57810 10 GbE NIC does not support 10 Gbps or 1 Gbps WOL link speed.
Solution: The BCM57810 10 GbE NIC can only support 100 Mbps WOL link speed due to power consumption limitations.
Problem: When setting the Jumbo MTU property to 5000 bytes or greater and forcing Flow Control on network adapters
that support a link speed of 10 Gbps, the system performance performs at less than optimal levels.
Solution: If Jumbo MTU is set to 5000 bytes or greater, ensure that Flow Control is set to Auto.
Problem: iSCSI Crash Dump is not working in Windows.
Solution: After upgrading the device drivers using the installer, the iSCSI crash dump driver is also upgraded, and iSCSI
Crash Dump must be re-enabled from the Advanced section of the BACS Configuration tab.
Problem: In Windows Server 2008 R2, if the OS is running as an iSCSI boot OS, the VolMgr error, “The system could not
successfully load the crash dump driver,” appears in the event log.
Solution: Enable iSCSI Crash Dump from the Advanced section of the BACS Configuration tab.
Problem: The Broadcom NetXtreme II adapter may not perform at optimal level on some systems if it is added after the
system has booted.
Solution: The system BIOS in some systems does not set the cache line size and the latency timer if the adapter is added
after the system has booted. Reboot the system after the adapter has been added.
Problem: Although the Broadcom 5708S SerDes adapter is capable of connecting at speeds up to 2.5 Gbps when licensed
and configured, Windows Task Manager incorrectly reports the speed at 2 Gbps.
Solution: This reporting error is a known Microsoft issue. Locate the actual link speed from Viewing Vital Signs in BACS.
Problem: Cannot configure Resource Reservations in BACS after SNP is uninstalled.
Solution: Reinstall SNP. Prior to uninstalling SNP from the system, ensure that NDIS is enabled via the checkbox on the
Resource Configuration screen, available from the Resource Reservations section of the Configurations tab (see Viewing
Resource Reservations). If NDIS is disabled and SNP is removed, there is no access to re-enable the device.
Problem: TOE performance is more susceptible to packet loss when flow control is disabled.
Solution: Enable flow control to reduce the number of packets lost.
Problem: A DCOM error message (event ID 10016) appears in the System Even Log during the installation of the Broadcom
adapter drivers.
Solution: This is a Microsoft issue. For more information, see Microsoft knowledge base KB913119 at http://
support.microsoft.com/kb/913119.
Problem: Performance is degraded when multiple BCM57710 network adapters are used in a system.
