• Speed, Duplexity and Autonegotiation
The exact steps involved in configuring your Gigabit Ethernet card will vary
depending on the type of card you have. The following information should be helpful:
NOTE Any changes made to your configuration files will not take effect until you reboot the
system.
— Ethernet partners are two Ethernet devices which are connected by an Ethernet
cable (CAT5 or Fiber). For example, two Ethernet cards connected directly to
each other by a cable, or an Ethernet card connected to an Ethernet hub or
switch.
— You may set the speed and duplexity for Ethernet partners manually or allow
the card to automatically set themselves by turning autonegotiate on. Set the
partners according to the Supported Configurations table in Chapter 1.
— Setting the speed and duplexity parameters for 1000Base-T cards is done
differently than for 1000Base-SX cards. The following information describes
both:
— 1000Base-T cards
To configure the card for autonegotiation, enter the AUTO_ON parameter in
the driver configuration file. If your driver is gelan, then the file would be
/etc/rc.confi.d/hpgelanconf, and the entry would be:
HP_GELAN_SPEED=AUTO_ON
If your driver is igelan, then the file would be /etc/rc.confi.d/hpigelanconf, and
the entry would be:
HP_IGELAN_SPEED=AUTO_ON
To configure the card manually, enter the appropriate parameter from the
table below in the driver configuration file. If your driver is gelan, then the
file would be /etc/rc.confi.d/hpgelanconf, and the entry would be:
HP_GELAN_SPEED= <parameter>
If your driver is igelan, then the file would be /etc/rc.confi.d/hpigelanconf, and
the entry would be:
HP_IGELAN_SPEED= <parameter>
