4-6 Configuring the Network Interface
Rev. 1.0 Copyright © 2000–2001 by LSI Logic Corporation. All rights reserved.
After the Openboot PROM probes the adapter’s FCode PROM, a
local-mac-address property is created in the adapter’s device node. The
property’s value corresponds to the Ethernet number that can be used
with the adapter.
The device driver, or any other qfe adapter utility, can use this
local-mac-address property for configuring that Ethernet interface.
4.4.5 Conflicting With Fast Ethernet Switches
There are two Fast Ethernet (100BASE-T) switches that may present
difficulties when working with the ITI8241C-S Fast Ethernet PCI adapter:
•
Bay Networks model 28115/ADV
•
SynOptics model 28115
If you use the adapter with these switches, you will encounter difficulties.
Please refer to the Sun Microsystems bug ID 4071199 for more
information. A patch is available from Sun Microsystems that fixes these
difficulties.

4.4.6 Increasing Performance on Enterprise Servers
If you deploy four ITI8241C-S Four Port Fast Ethernet adapters in an
Enterprise Server, you may experience slow performance and response
times during peak periods of high network traffic. This poor performance
is usually caused by applications that use data buffer and socket buffer
sizes greater than 8 Kbytes.
Improved performance can be achieved by adjusting the application’s
data buffer size to be less than or equal to 8 Kbytes.
