Which interface is net2 and net3 ?

UNIX Solaris
1

Hi,
This is Solaris-10, T4-4 machine. Datacenter guy has plugged two cat6 cables in net2 and net3 interface. Other end which is going to switch port is already patched for both.
I need to configure two IP's on two NIC interfaces, but not able to figure out, which are the ports cable is plugged in. igb0 and igb1 are already in use.

Is there any short way to know instead of plumbing all interfaces and configure IP and then try to make it up ?

dladm show-ether

dladm show-phys

ipadm

NOTE: ipadm will not show the interfaces up until you have actually established communications with the network.

Seems like those commands are for Solaris-11.

When I say net2 and net3, it means that was written on that port where cable was plugged in on back side.

Try running prtdiag and looking for NET2 and NET3. This will show a device path for the interface. Use grep to look for that path in /etc/path_to_inst. The last two path_to_inst fields are the instance number and the instance name. The line will look like this: <path> 2 "igb" or similar. In this example, the device would be igb2.

Hope this helps.

It is looking like this -->

/# prtdiag -v | egrep -i "net2|net3"
/SYS/RIO/NET2     PCIE  network-pciex8086,10c9
/SYS/RIO/NET3     PCIE  network-pciex8086,10c9
 
/# cat /etc/path_to_inst | grep -i igb
"/pci@400/pci@1/pci@0/pci@2/network@0" 0 "igb"
"/pci@400/pci@1/pci@0/pci@2/network@0,1" 1 "igb"
"/pci@600/pci@1/pci@0/pci@4/network@0" 2 "igb"
"/pci@600/pci@1/pci@0/pci@4/network@0,1" 3 "igb"
"/pci@600/pci@1/pci@0/pci@4/network@0,2" 4 "igb"
"/pci@600/pci@1/pci@0/pci@4/network@0,3" 5 "igb"
"/pci@600/pci@2/pci@0/pci@3/network@0" 6 "igb"
"/pci@600/pci@2/pci@0/pci@3/network@0,1" 7 "igb"
 /# cat /etc/path_to_inst | grep -i 10c9
 /# cat /etc/path_to_inst | grep -i 8086
 /#

prtdiag prints multiple lines per device. You need to look at the second line under NET2 and NET3. That will have the path.

Looking at your path_to_inst data, I would suspect NET2 is igb6 and NET3 is igb7. igb2-5 looks to be a quad network card.

Ok, here I got -->

/SYS/RIO/NET2     PCIE  network-pciex8086,10c9
                        /pci@600/pci@2/pci@0/pci@3/network@0
/SYS/RIO/NET3     PCIE  network-pciex8086,10c9
                        /pci@600/pci@2/pci@0/pci@3/network@0,1
 /# cat /etc/path_to_inst | grep -i "/pci@600/pci@2/pci@0/pci@3/network@0"
"/pci@600/pci@2/pci@0/pci@3/network@0" 6 "igb"
 /# cat /etc/path_to_inst | grep -i "/pci@600/pci@2/pci@0/pci@3/network@0,1"
"/pci@600/pci@2/pci@0/pci@3/network@0,1" 7 "igb"

Does it mean that it is igb6 and igb7 ?

You are correct. I am able to configure IP on them. Thanks

Great!!

Indeed they are, all I saw was Sparc T4-4. My apologies.
