AD193A/AD194A PCI-X 4 Gigabit Fibre Channel and Gigabit Ethernet Combination Card Overview

Hardware and Software Installation Procedure

Optional Step: Configure Jumbo Frames Size (Jumbo frames are supported only at 1000 Mbit/s)

• Jumbo frames for the iether driver on HP-UX 11i v1 and HP-UX 11i v2 of September 2004 (or later) have an MTU in the

range of 1501 to 9000 bytes.

If you are using Jumbo Ethernet frames, ensure that:

— all end stations on a given LAN

have the same maximum transmission unit (MTU) setting;

— intermediate stations such as switch ports in your LAN have an MTU equal to or greater than the end station’s MTU.

• Obtain the PPA number of the card by entering lanscan.

• Choose one of two configuration methods that will permanently save your configuration.

— use the GUI-based system admin manager (SAM).

To use SAM, type sam at the HP-UX system prompt; then double-click Networking and Communications, and then

Advanced Configuration--see Ethernet Support Guide for details, and then do the steps for verifying the MTU size;

edit the following configuration file using an editor such as “vi”:

/etc/rc.config.d/hpietherconf.

Set the mtusize by editing:

HP_iether_MTU[i]=mtusize , and insert the proper interface name:

HP_iether_MTU[i]=HP_iether_INTERFACE_NAME. When the system reboots, the interface will be configured for

jumbo frame operation.

• Verify MTU change by entering netstat -rn. If MTU has not changed, enter the following commands:

$ifconfig lan PPA_number unplumb

$ifconfig lan PPA_number ip_address netmask netmask up

• To check (or verify) the current Ethernet frame size, enter:

$lanadmin -m PPA_number

An alternative way to temporarily configure jumbo frame size is to enter:

lanadmin -M mtu_size PPA_number.

Using lanadmin is temporary because it will not preserve your settings across reboots.

The PPA_number is the one we obtained from the output of lanscan. For using Jumbo Frames with the iether Gigabit

Ethernet driver on HP-UX 11i v1 or HP-UX 11i v2 of September 2004 (or later), set the mtu_size to a number in the range of

1501 to 9000 bytes.

For Further Information

For further information on the Gigabit Ethernet and Fibre Channel as implemented in this card, please refer to

http://docs.hp.com and then look under Networking and Communications. This card’s information is primarily located

under the subsection called “Combination Cards.”

1. In the Jumbo Frames discussion, “LAN” means that the end stations do not have any routers or layer 3 switches in

between them.
