AD386A PCIe 10 Gigabit Ethernet Card Overview

Product Overview

10 Gigabit Ethernet Link Settings

This section explains the options available in lanadmin to support the 10 Gigabit Ethernet driver. The lanadmin(1M) tool is

used to display and set parameters. Table 2 lists the parameters that can be set with lanadmin -X or displayed with lanadmin -x.

NOTE When your system is rebooted, settings that were made via the lanadmin(1M) command will be lost. To

retain configuration settings permanently in the configuration file (/etc/rc.config.d/

hpicxgbeconf),

use the NCWeb (HP-UX 11i v3) or SAM(HP-UX 11i v2) utility or manually edit the configuration file.

Option Setting

help Lists the -X or -x options.

-x card_info Displays adapter and driver revision and settings.

-x speed Displays the speed and duplexity of the link. The card always operates at 10Gbits/s, full

duplex mode. Autonegotiation is also not supported.

-x vmtu Displays the value of the virtual MTU for TCP Segmentation Offload (TSO). For details, see

TCP Segmentation Offload. Default: On.

-x cko Displays the driver checksum offload (CKO) settings.

-x drv_pr Displays whether the adapter/driver supports large packet reassembly for incoming TCP

packets.

-x drv_coal Displays driver interrupt coalescing thresholds and ranges.

-x drv_fctrl Displays the driver flow control settings.

-x drv_mq Displays information on driver queues.

-x help Displays available commands to get driver settings.

-x vpd

Displays

HP Vital Product Data of the adapter. NOTE: The initial EFI driver version

supported is 1.0.0.02. The VPD may display 1.0.0.f as the EFI driver version, but both EFI

driver versions are equivalent.

-X vmtu Sets the TSO vmtu value. For details, see TCP Segmentation Offload. Default: On.

-X recv_cko_on Enables hardware TCP/UDP (IPv4) checksum offload on receive. The receive side CKO is

On (enabled) by default.

-X recv_cko_off Disables hardware TCP/UDP (IPv4) checksum offload on receive. The receive side CKO is

On (enabled) by default.

-X send_cko_on Enables hardware TCP/UDP (IPv4) checksum offload on transmit. The transmit side CKO is

ON (enabled) by default. For details, see Checksum Offload.

-X send_cko_off Disables hardware TCP/UDP (IPv4) checksum offload on transmit. The transmit side CKO is

ON (enabled) by default. For details, see Checksum Offload. When transmit CKO is disabled,

TSO is also implicitly disabled.
