46 Sun Quad FastEthernet 6U CompactPCI Adapter Installation and User’s Guide • June 2000
If the adapter is connected to a link partner with which the autonegotiation protocol
fails to operate successfully, you can configure the device not to use this protocol
and force the driver to set up the link in the mode and speed of your choice. See
“Setting Forced Mode Using the
ndd Utility” on page 70 for more information.
Setting the local-mac-address
Property
Each of the four network interfaces of the adapter has been assigned a unique
medium access control (MAC) address, which represents the 48-bit Ethernet address
for that network interface. The OpenBoot firmware reports this MAC address by
means of the
local-mac-address property 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 the device. A network interface’s
MAC address can be used when booting over the network.
The mac-address property 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 interfaces of the adapter, set the
NVRAM configuration variable
local-mac-address? to true , as shown in the
procedure below.
▼ To Set the local-mac-address Property to the
Network Interfaces
Before starting this procedure, make sure that all network activity over the adapter’s
network interfaces has stopped.
1. Log in to the system as superuser.
Refer to the system’s documentation for the correct procedure. For example, if you
are logging into a Netra ct series server, refer to the Netra ct Server Service Manual.
