Sun Microsystems Ethernet PCI-X Adapter manual Configuring the Network Host Files

Page 31

Configuring the Network Host Files

After installing the driver software, you must create a hostname.ixgenumber file where number = the instance number of the ixge interface.) for the adapter’s Ethernet interface. You must also create both an IP address and a host name for its Ethernet interface in the /etc/hosts file.

Caution – Ensure that the optical transceiver is correctly seated before configuring the interface.

1.At the command line, use the grep command to search the /etc/path_to_inst file for ixge interfaces.

#grep ixge /etc/path_to_inst "/pci@9,600000/ethernet@1" 0 "ixge"

In the example above, the device instance is from a Sun 10-Gigabit Ethernet PCI-X adapter. For clarity, the instance number is in bold italics.

2.Use the ifconfig command to set up the adapter’s ixge interface.

Use the ifconfig command to assign an IP address to the network interface. Type the following at the command line, replacing ip-addresswith the adapter’s IP address:

#ifconfig ixge0 plumb ip-addressup

Caution – If the optical transceiver is unplugged after the interface has been configured using the ifconfig command, you must unconfigure and reconfigure the interface.

On Solaris operating systems, use the following commands to unconfigure and reconfigure the interface:

#ifconfig ixge0 down

#ifconfig ixge0 unplumb

#ifconfig ixge0 plumb ip-addressup
