Ethernet Support Guide for HP-UX 11i v3

The ppa is obtained from the output of the lanscan command (for an example, see Section 2.3
(page 16)).
To set the parameter for multiple ports or functions, enter the nwmgr command multiple times,
specifying a unique PPA each time.
Parameter values that are set with the nwmgr command take effect immediately. They do not persist
across reboots unless the --sa option is specified with the command.
Setting Ethernet parameters in a configuration file — changes take effect at
next startup
In the driver's configuration file, you set the parameter value for a specific port by appending the
port number in brackets to the parameter name, in the following format:
parameter-name[ppa]
For example, to turn off transmit flow control on port 2 of an iocxgbe driver, specify the
HP_IOCXGBE_TX_FLOW_CONTROL parameter as follows:
HP_IOCXGBE_TX_FLOW_CONTROL[2]=OFF
The configuration file allows you to apply the value to all ports or functions on the device by omitting
the “[ppa]” string.
Changes to the configuration file parameter values take effect the next reboot or when running the
driver's startup script. The configuration file defines and saves parameter values so that they persist
across reboots.
Using startup scripts to test configuration file settings and apply them to the
running system
The startup script applies the configured values to the kernel during run time. The startup script is
executed automatically after each reboot. You can also run a startup script manually by providing
the argument start, as in the following command example for an iexgbe driver's startup script:
/sbin/rc2.d/S307hpiexgbe start
This startup feature allows you to experiment with the current values. When a desired configuration
is achieved, you can then preserve it for posterity. HP recommends setting tested values permanently
to persist across reboots.
Names and locations of driver configuration files and startup scripts
Table 6 (page 22) lists each driver's configuration file and startup script along with their location
on the system. Edit configuration files using an editor such as vi.
