Sun FastEthernet PCI Adapter Installation and User’s Guide • July 1997  
 
 
Auto-Negotiation  
A key feature of the Sun FastEthernet PCI Adapter is auto-negotiation. The  
auto-negotiation protocol, as specified by the 100BASE-T standard, selects the  
operation mode (half-duplex or full-duplex) and auto-sensing protocol selects the  
speed (10 Mbps or 100 Mbps) for the adapter.  
The link speed and modes supported by the Sun FastEthernet PCI Adapter are listed  
as follows in decreasing order of priority:  
100 Mbps, full-duplex  
100 Mbps, half-duplex  
10 Mbps, full-duplex  
10 Mbps, half-duplex  
When the system is booted, the Sun FastEthernet PCI Adapter advertises these  
capabilities to the Link Partner at the other end of the link (a hub, switch, or another  
network interface card (NIC) in a host system). If the Link Partner also supports  
auto-negotiation, it will advertise its capabilities over the link. The common highest  
priority mode supported by both sides is selected automatically for the link  
operation.  
If the Sun FastEthernet PCI Adapter is connected to a remote system or to an  
interface that is not capable of auto-negotiation, your system automatically selects  
the speed and half-duplex mode.  
If the Sun FastEthernet PCI Adapter is connected to a Link Partner in which  
auto-negotiation protocol is not operational, you can configure the device to not use  
this protocol and force the driver to set up the link in the mode and speed of your  
choice.  
Refer to the Platform Notes: The hme Fast Ethernet Device Driver document for more  
information on the hmedevice driver and auto-negotiation. This document is also  
available in the Solaris AnswerBook.

Monitoring Network Activity  
Perform the following task to verify that the system recognizes the Ethernet  
connection. Make sure that you are connected to an active network.  
To monitor network activity or incoming network packets, type the following at  
the okpromp:  
ok apply watch-net <full path name of the hmeinterface>  
Internal loopback test -- succeeded.  
Transceiver check -- passed.  
Looking for Ethernet Packets.  
‘.’ is a Good Packet. ‘X’ is a Bad Packet.  
Type any key to stop.  
............................................  
Note – In the example above, <full path name of the hmeinterface> is the full path name  
of the hmeinterface. Use the show-devscommand at the okprompt to display the  
full path name of the hmedevice.  
Rebooting the System  
After you have examined the network activity, perform a reconfiguration boot on  
your system so the operating environment can recognize the Sun FastEthernet PCI  
Adapter.  
Perform a reconfiguration boot on the system.  
ok boot -r  
Refer to the Solaris 2.x Peripherals Handbook for more information.

Sun FastEthernet PCI Adapter Installation and User’s Guide • July 1997  
 
   
Configuring Host Files  
After installing the Sun FastEthernet PCI Adapter, you must create a  
hostname.hme<num> file for its Ethernet interface. You must also assign an  
IP address and a hostname for its Ethernet interface in the /etc/hostsfile.  
Your system motherboard Ethernet interface (network) uses the hmedriver as well,  
with an interface identified as hme0. (The number 0following hmerepresents the  
first instance of the interface.)  
You may see the interface(s) represented in the /etc/path_to_instfile.  
To Prepare Your System for the Sun FastEthernet  
PCI Adapter  
1. Create an /etc/hostname.hme1file.  
The number 1following hmerepresents the second instance of the hmedevice. Use  
the hme2extension for a second FastEthernet adapter, and so on.  
Do not create /etc/hostname.hme<num> files for the Sun FastEthernet PCI  
Adapter channels you do not plan to use. The /etc/hostname.hme<num> file  
must contain the hostname for the appropriate network interface.  
The hostname should have an IP address and should be entered in the  
/etc/hostsfile.  
The hostname should be different from any other hostname of any other interface,  
for example: /etc/hostname.hme0and /etc/hostname.hme1cannot share  
the same hostname.  
The following is an example of the /etc/hostname.hme<num> files required for  
a machine called zardozthat will be known as zardozand zardoz-1on the  
networks connected to the hme0and hme1Ethernet interfaces.  
zardoz # cat /etc/hostname.hme0  
zardoz  
zardoz # cat /etc/hostname.hme1  
zardoz-1  
Chapter 3  
Using the Sun FastEthernet PCI Adapter  
11  
 
     
2. Create an appropriate entry in the /etc/hostsfile for each active hmechannel.  
Using the example in Step 1, you will have:  
zardoz # cat /etc/hosts  
...  
127.0.0.1  
localhost  
129.144.10.57 zardoz  
129.144.11.83 zardoz-1  
loghost  
Booting from the Network  
You can use the Sun FastEthernet PCI Adapter interface as the boot device for your  
system.  
To Boot from the Network  
1. At the okprompt, type:  
ok show-devs  
The show-devscommand lists the system devices. You should see the full path  
name of the hmedevice, similar to this example:  
/pci@1f,2000/SUNW,hme@1,1  
2. Type:  
ok boot /pci@1f,2000/SUNW,hme@1,1

Sun FastEthernet PCI Adapter Installation and User’s Guide • July 1997  
 
   
Post-Installation Procedures (Optional)  
Perform the tasks in the following sections to customize the performance of the Sun  
FastEthernet PCI Adapter.  
Configuring Driver Parameters  
The hmedevice driver controls the SUNW,hmeEthernet device. The device driver  
automatically selects the link speed using the auto-negotiation protocol with the link  
partner. (See “Auto-Negotiation” on page 9.)  
You can manually configure the hmedevice driver parameters to customize each  
SUNW,hmedevice in your system in three ways:  
Configure the hmedriver parameters generally for all SUNW,hmedevices in the  
system by entering the parameter variables in the /etc/systemfile.  
Set a parameter on a per-device basis by creating the hme.conffile in the  
/kernel/drvdirectory.  
Use the ndd(1M)utility to temporarily change a parameter. This change is lost  
when you reboot the system.  
Refer to the Platform Notes: The hme Fast Ethernet Device Driver document for more  
information on configuring driver parameters. This document is also available on  
the Solaris AnswerBook.  
Increasing TCP/ IP Performance  
You can increase the TCP/ IP performance of the Sun FastEthernet PCI Adapter by  
changing the TCP highwater mark to 64K. This can be done with the ndd(1M)  
utility as shown in the following procedure.  
Chapter 3  
Using the Sun FastEthernet PCI Adapter  
13  
 
     
To Increase TCP/ IP Performance  
As superuser, type:  
# ndd -set /dev/tcp tcp_xmit_hiwat 65535  
# ndd -set /dev/tcp tcp_recv_hiwat 65535  
# ndd -set /dev/tcp tcp_cwnd_max 65534  
The changes will take effect immediately and affect all system networking interfaces.  
Forcing Network Speed Between 10 Mbps and  
100 Mbps  
To Force Network Speed Between 10 Mbps and 100 Mbps  
1. At the okprompt, use the show-devscommand to list the system devices.  
The full path name of the hmedevice, similar to this example, is displayed:  
/pci@1f,2000/SUNW,hme@1,1  
2. Type:  
ok nvedit  
3. Type the following, pressing the Return key at the end of line 0:  
0: probe-all install-console banner  
1: apply transfer-speed=10 <full path name of the hme device>  
4. Press the Control-C keys after typing <full path name of the hme device>.  
Note – In the above example, the speed is forced to 10 Mbps. To force the speed to  
100 Mbps, replace 10with 100.

Sun FastEthernet PCI Adapters  
local-mac-addressProperty  
The network interface of the Sun FastEthernet PCI Adapter is assigned a unique  
MAC (Media Access Control) address, which represents the 48-bit ethernet address  
for the channel. The OpenBoot™ firmware reports this MAC address via the  
local-mac-addressproperty in the device nodes corresponding to the network  
interfaces.  
A system is not obligated to use this assigned MAC address if it has a system-wide  
MAC address. In such cases, the system-wide MAC address applies to all network  
interfaces on the system.  
The device driver, or any other adapter utility, can use the network device's MAC  
address (local-mac-address) while configuring it. In future Solaris releases, you  
will be able to use the channel's MAC address when booting over the network.  
The mac-addressproperty of the network device specifies the network address  
(system-wide or local-mac-address) used for booting the system. To start using  
the MAC addresses assigned to the network interface of the Sun FastEthernet PCI  
Adapter, set the NVRAM configuration variable local-mac-address?to true.  
ok setenv local-mac-address? true

External Transceivers  
Some external transceivers support multiple link capabilities, such as 100BASE-T4,  
100BASE-TX, and 10BASE-T, but not auto-negotiation. In this case, the driver  
attempts to bring-up the link in the highest priority capability in the following  
descending order of priority:  
100BASE-T4  
100BASE-TX  
10BASE-T  
To bring-up your external transceiver in a lower priority capability, you must  
configure the driver parameters to force the link to the desired mode.  
Refer to your external transceiver documentation or the Platform Notes: The hme Fast  
Ethernet Device Driver document for more information on forcing the link mode.  
When using an external transceiver with the Sun FastEthernet PCI Adapter,  
your system may not report the speed at which the link is operating, either  
10 or 100 Mbps.

Using the selftestDiagnostics  
The following tests are available to help identify problems when the system  
containing the Sun FastEthernet PCI Adapter does not boot.  
The FCode selftestis added to the device tree during the probing phase of the  
OpenBoot PROM start-up sequence. You can invoke the FCode selftest  
diagnostics by using the OpenBoot user interface testor test-allcommands. If  
you encounter an error while running the diagnostics, appropriate messages will be  
displayed. Refer to the OpenBoot 3.x Command Reference Manual for more information  
on the testand test-allcommands.  
selftestexercises most functionality of the adapter sub-section by sub-section and  
checks for the following conditions:  
Isolates faulty FRUs  
Checks, with a high confidence, that no hardware fault exists on  
No Trouble Found (NTF)  
Checks connectivity during adapter card installation  
Verifies that all components are functional
