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/
hpixgbeconf), use
the SAM utility or manually edit the configuration file.
Table 2 Link Card Parameters that lanadmin can Display (-x) or Set (-X)
Option Setting
help Lists the -X or -x options
-x card_info Displays adapter and driver revision and settings
-x cko Gets the driver checksum offload (CKO) settings
-x drv_coal Displays driver interrupt coalescing thresholds and ranges
-x drv_fctrl Gets the driver flow control settings
-x drv_mq Gets the number of driver queues
-X fctrl_thresh Sets flow control threshold. Default: 75
-X rx_coal Sets receive interrupt coalescing ranges and frame counts
Usage: lanadmin -X [tx|rx]_coal rng R1 R2 R3 frc A B C D timer T1 <ppa>
Note: When using jumbo frames (9000 MTU), the optimal setting for receive interrupt
coalescing is different than the default. For setting this, see the Receive Interrupt Coalescing
section in this guide.
-X tx_coal Sets transmit interrupt coalescing ranges and frame counts
-X rx_fctrl Sets receive side flow control (generate pause frames). The range of values is: on/off. Default:
On.
-X tx_fctrl Sets transmit side flow control (response to pause frames). The range of values is: on/off.
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. When transmit cko is disabled,
TSO is also implicitly disabled.
-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.
