1 10GigEthr-02 overview NOTE: The Web 1301 release of 10GigEthr-02 has been replaced by the equivalent AR 1303 release. For more information, see the 10GigEthr-02 (iexgbe) B.11.31.1303 Ethernet Driver Release Notes. The 10GigEthr-02 bundle contains the PCIe 10 Gigabit Ethernet iexgbe driver.
Flex-10 HP Flex-10 allows each 10 Gigabit Ethernet adapter to be configured by HP-UX as eight LAN devices. Each port in a dual-ported mezzanine or LOM represents a single, wired connection to network hardware as follows: • In a Blade Virtual Connect environment, the NIC is configured in Flex-10 mode. Each port is logically divided into up to four individual network devices which share the total bandwidth of the network connection. For more information about HP Virtual Connect, see http:// h18004.www1.hp.
• TCP segment reassembly in driver • Jumbo Frames • Multicast and Promiscuous mode • IPv6 • IEEE 802.

lan3 current values: New Transmit Flow Control = Off NOTE: The warning message incorrectly displays the Tx flow control state as Off when it should be On. This is a known issue (see “Known problems and limitations” (page 8)). • Attempting to turn on Rx flow control for a Flex-10 interface on which the MTU size is greater than 1500 (enabling Jumbo Frames) brings up the warning message shown in the following example.

systems with MC/Serviceguard might exhibit a system Transfer Of Control (TOC), thereby inhibiting Serviceguard recovery from a link outage or network connectivity problem. Severity: Medium Workaround: Resolve the problem by resetting the link. Statistics will then be collected and updated properly.
• Rx flow control is disabled in Flex-10 mode In Flex-10 mode (Virtual Connect), Rx Flow control is disabled by default. Attempts to enable Rx flow control are not honored by the driver, because the driver and hardware cannot determine whether Jumbo Frames are disabled across all FlexNICs. Severity: Medium Workaround: No workaround necessary. • Using ncweb to change number of receive queues causes an error message.
