Sun Microsystems Gigabit Ethernet MMF/UTP Adapter To Specify Device Instances for the ndd Utility

▼To Specify Device Instances for the ndd Utility

Before you use the ndd utility to get or set a parameter for a ipge device, you must specify the device instance for the utility.

1.Check the /etc/path_to_inst file to identify the instance associated with a particular device.

#grep ipge /etc/path_to_inst "/pci@780/pci@0/pci@1/network@0" 0 "ipge" "/pci@780/pci@0/pci@1/network@0,1" 1 "ipge" "/pci@780/pci@0/pci@8/network@0" 2 "ipge" "/pci@780/pci@0/pci@8/network@0,1" 3 "ipge" "/pci@7c0/pci@0/pci@2/network@0" 4 "ipge" "/pci@7c0/pci@0/pci@2/network@0,1" 5 "ipge" "/pci@7c0/pci@0/pci@9/network@0" 6 "ipge" "/pci@7c0/pci@0/pci@9/network@0,1" 7 "ipge"

The instance numbers in the previous example are in bold italics for clarity. Instances 0, 1, 4, and 5 are 4 on-board ipge copper ports. Instances 2 and 3 are dual- port ipge PCI-Express Dual Gigabit Ethernet MMF device (in PCI-E slot 0) Instances

6and 7 are dual-port ipge PCI-Express Dual Gigabit Ethernet UTP device (in PCI-E slot 1).

2.Use the instance number to select the device.

#ndd -set /dev/ipge instance instance-number

For example:

#ndd -set /dev/ipge instance 6

The device remains selected until you change the selection.

Noninteractive and Interactive Modes

You can use the ndd utility in two modes:

■Noninteractive
