1 Installing and Conf iguring the ge Device Driver These Platform Notes include instructions for installing and configuring the software used by the Sun GigabitEthernet adapter .
2 Platform Notes: The Sun GigabitEthernet Device Driver • March 1999 2. Use the prtconf -pv command to determine if the system already contains a GigabitEthernet ( ge ) device. For Sun GigabitEthernet/S : For Sun GigabitEthernet/P: 3. Install the software.
Installing and Configuring the ge De vice Driver 3 2. Use the grep command to search the /etc/path_to_inst f ile for ge instances. For Sun GigabitEthernet/P: For Sun GigabitEthernet/S: In these examples, the 0 instance is for the first GigabitEthernet adapter installed in each system.
4 Platform Notes: The Sun GigabitEthernet Device Driver • March 1999 Conf iguring the Driver Parameters This section provides an overview of the capabilities of the GigabitEthernet ASIC used in the adapters, lists the available ge driver parameters, and describes how to configur e these parameters.
Installing and Configuring the ge De vice Driver 5 Driver Parameter V alues and Def initions T ABLE 1 describes the parameters and settings for the ge driver .
6 Platform Notes: The Sun GigabitEthernet Device Driver • March 1999 Def ining the Current Status The read-only parameters described in T ABLE 2 explain the operational mode of the interface. Based on the value of these parameters, you can determine the current status of a link.
Installing and Configuring the ge De vice Driver 7 Interpacket Gap Parameters The GEM ASIC supports the programmable Interpacket Gap (IPG) parameters ipg1 and ipg2 . The total IPG is the sum of ipg1 and ipg2 : 0.096 microseconds for the link speed of 1000 Mbps.
8 Platform Notes: The Sun GigabitEthernet Device Driver • March 1999 T ABLE 5 defines the lance_mode and ipg0 parameters. Operational Mode Parameters T ABLE 6 describes the operational mode parameters and their default values.
Installing and Configuring the ge De vice Driver 9 Reporting Local PCS Capabilities T ABLE 7 describes the read-only PCS capabilities that GEM PCS supports. These parameters define the capabilities of the hardwar e. Reporting the Link Partner Capabilities T ABLE 8 describes the read-only link partner capabilities.
10 Platform Notes: The Sun GigabitEthernet Device Driver • March 1999 If the link partner is not capable of autonegotiation (when lp_1000autoneg_cap is 0) the remaining information described in T ABLE 8 is not relevant and the parameter value = 0.
Installing and Configuring the ge De vice Dr iver 11 ▼ T o Specify the Device Instance for the ndd Utility Before you use the ndd utility to get or set a parameter for a ge device, you must specify the device instance for the utility . 1. Check the /etc/path_to_inst f ile to identify the instance associated with a particular device.
12 Platform Notes: The Sun GigabitEthernet Device Driver • March 1999 ▼ T o Use the ndd Utility in Non-Interactive Mode This section describes how to modify and to display parameter values.
Installing and Configuring the ge De vice Dr iver 13 ● T o list all the parameters supported by the ge driver , type ndd /dev/ge ? . (See T ABLE 1 through T ABLE 8 for parameter descriptions.) Autonegotiation Mode By default, autonegotiation is set to on .
14 Platform Notes: The Sun GigabitEthernet Device Driver • March 1999 2. Set adv_1000autoneg_cap to 0 . Setting Parameters Using the ge.conf File Y ou can also specify the properties described in this section on a per-device basis by creating a ge.conf f ile in the /kernel/drv directory .
Installing and Configuring the ge De vice Dr iver 15 Note – The “name” property in the ge.conf file should be the same value as the “compatible” property . In this case, the value is SUNW,sbus-gem . See page 7 for more information about the .
16 Platform Notes: The Sun GigabitEthernet Device Driver • March 1999 ▼ T o Set Parameters Using the ge.conf File on a PCI adapter 1. Set the ipg1 and ipg2 parameters for the above devices in the kernel/drv/ge.conf file. 2. Save the ge.conf f ile.
Installing and Configuring the ge De vice Dr iver 17 1. At the command line, use the grep command to search the /etc/path_to_inst f ile for ge interfaces. For Sun GigabitEthernet/P : The following example shows the device instance fr om an adapter installed in slot 1.
18 Platform Notes: The Sun GigabitEthernet Device Driver • March 1999 3. Create an appropriate entry in the /etc/hosts f ile for each active ge interface.
Installing and Configuring the ge De vice Dr iver 19 ▼ T o Perform a Net-Install of the Solaris Envir onment Over the ge Interface This procedur e is applicable only if you are installing the Solaris operating environment over the network using the ge interface.
20 Platform Notes: The Sun GigabitEthernet Device Driver • March 1999 3. At the ok prompt, type: The show-nets command lists the system devices. Y ou should see the full path name of the network device, similar to the examples below . For Sun GigabitEthernet/P: For Sun GigabitEthernet/S: 4.
Un punto importante, dopo l’acquisto del dispositivo (o anche prima di acquisto) è quello di leggere il manuale. Dobbiamo farlo per diversi motivi semplici:
