Parameter Value Description
TransmitMaxBD
1 to 500 (*3)
(default: 128)
The number of buffer descriptor to wait
for an interrupt for transmitting is
specified. (*5)
fjgi* (*6)
<LinkSpeed_A>
:<DuplexCapabilities_A>
:<FlowControl_A>
:<fjgi_mtu>
:<AutoNegotiation_A>
:<Role_A>
:<ReceiveTicks>
:<TransmitTicks>
:<ReceiveMaxBD>
:<TransmitMaxBD> (*7)
Parameter setting values are specified for
every instance.
Refer to the description of each parameter
for the meaning of each value.
*1: Parameter is supported on 10/100/1000Base-T (SE0X7GD1X, SE0X7GQ1X, SE0X7GQ2X) adapters only.
*2: Parameter is effective only when AutoNegotiation_A=On. When AutoNegotiation_A=Off, it becomes FlowControl_A=None.
*3: Specify the value as a decimal figure.
*4: Parameter is supported on 10/100/1000Base-T (SE0X7GD1X, SE0X7GQ1X, SE0X7GQ2X) adapters in 1000Mbps mode only.
*5: These ReceiveTicks, TransmitTicks, ReceiveMaxBD or TransmitMaxBD parameters are tuning parameters about the performance.
*6: Please put a decimal number (instance number) in place of the asterisk (
*
).
The fjgi* parameter is used prior to parameters to all instances if the fjgi parameter is specified with LinkSpeed_A,
DuplexCapabilities_A, FlowControl_A, fjgi_mtu, AutoNegotiation_A, Role_A, ReceiveTicks, TransmitTicks, ReceiveMaxBD or
TransmitMaxBD parameters.
*7: The default values are used when setting values are omitted.
[Parameter Setting]
The following examples show how to set the fjgi.conf file.
- The location of the fjgi.conf file depends on the model of the host system as described below:
1. SPARC Enterprise Txxxx series and SPARC T3 series
/platform/sun4v/kernel/drv/fjgi.conf
2. SPARC Enterprise Mxxxx series
/platform/SUNW,SPARC-Enterprise/kernel/drv/fjgi.conf
- How to set a parameter to all instances
Example 1: The parameters for all instances are set to "Auto-Negotiation is disabled", "Connect at 100Mbps" and "Half-Duplex
operation is enabled".
The parameter values need to be set by character strings like AutoNegotiation_A="Off", LinkSpeed_A="100" and
DuplexCapabilities_A="Half".
The following is added to the fjgi.conf file:
AutoNegotiation_A="Off"
LinkSpeed_A="100"
DuplexCapabilities_A="Half";
Example 2: The parameters for all instances are set to "Auto-Negotiation is enabled", "Connect at 100Mbps" and "Full-Duplex
operation is enabled".
