Solaris 11 – How to Create VNIC and Assign a IP ?

How to assign Static IP address in Solaris 11? Is it possible to assign multiple IP address to NIC ? First we will the basic difference between older version of Solaris and Solaris 11.In Solaris 10, according to the NIC manufacturer,physical network interfaces are named (Ex:bge,e1000g,nxge).But in Solaris 11 onwards,the inconsistencies names are hidden from the view and all the interfaces will be named as net0,net1…netx . 

If you want to know which “netx” name has been mapped to physical interface (Ex:bge0,e1000g,nxge), you can see those information using below command.

root@Unixarena-SOL11:~# dladm show-phys
LINK MEDIA STATE SPEED DUPLEX DEVICE
net0 Ethernet up 1000 full e1000g0
net1 Ethernet up 1000 full e1000g1
net2 Ethernet up 1000 full e1000g2
root@Unixarena-SOL11:~#

To show all dladm level devices,including VNIC’s & aggregation links,use the below command.

root@Unixarena-SOL11:~# dladm show-link
LINK CLASS MTU STATE OVER
net0 phys 1500 up --
net1 phys 1500 up --
net2 phys 1500 up --

In Solaris 11,you can give a meaning full description(net1/oracle_VIP) to all the IP address on the system unlike Solaris 10. (e1000g1:2)

 ASSIGNING A NEW IP TO NIC

Let see how to assign IP address to the  physical interface “net1″(e1000g1).
1.Plumb the IP interface

root@Unixarena-SOL11:~# dladm show-phys
LINK MEDIA STATE SPEED DUPLEX DEVICE
net0 Ethernet up 1000 full e1000g0
net1 Ethernet up 1000 full e1000g1
net2 Ethernet up 1000 full e1000g2
root@Unixarena-SOL11:~#
root@Unixarena-SOL11:~# ipadm create-ip net1


2.Assign the static IP address to net1.

root@Unixarena-SOL11:~# ipadm create-addr -T static -a local=192.168.2.200/24 net1/WebIP

Note:WebIP – IP description.

3.Verify  whether IP address is configured or not.

root@Unixarena-SOL11:~# ifconfig  net1
net1: flags=1000843 mtu 1500 index 7
inet 192.168.2.200 netmask ffffff00 broadcast 192.168.2.255
ether 0:c:29:98:1:e4
root@Unixarena-SOL11:~# ipadm
NAME CLASS/TYPE STATE UNDER ADDR
lo0 loopback ok -- --
lo0/v4 static ok -- 127.0.0.1/8
lo0/v6 static ok -- ::1/128
net0 ip ok -- --
net0/v4 static ok -- 192.168.2.51/24
net0/v6 addrconf ok -- fe80::20c:29ff:fe98:1da/10
net1 ip ok -- --
net1/WebIP static ok -- 192.168.2.200/24
root@Unixarena-SOL11:~#

You have successfully assigned the IP address to interface net1 (e1000g1).

VNIC(VIRTUAL INTERFACE)

Now you have a question in mind that, how to assign multiple IP address to single interface (Like Solaris 10′s  - e1000g1:1,e1000g1:2…..).  ?  Solaris 11 has brought the new concept called VNIC. You can create N no of VNIC’s using single physical interface and possible to create on top of aggregation as well.These VNIC are treated as actual physical interface and possible to assign to local zones with  full access to it.It is possible to run snoop on it.

You can also give a meaningful name to VNIC(virtual interface). Let’s see how can create a new VNIC using interface net2 (e1000g2).

1.List out the physical interface.

root@Unixarena-SOL11:~# dladm show-phys
LINK MEDIA STATE SPEED DUPLEX DEVICE
net0 Ethernet up 1000 full e1000g0
net1 Ethernet up 1000 full e1000g1
net2 Ethernet unknown 1000 full e1000g2
root@Unixarena-SOL11:~#


2.Create a new VNIC using net2 (e1000g2). Here the VNIC name “UnixArena1″

root@Unixarena-SOL11:~# dladm create-vnic  -l net2 UnixArena1


3.Plumb the virtual interface

root@Unixarena-SOL11:~# dladm create-vnic  -l net2 UnixArena1
root@Unixarena-SOL11:~# ipadm create-ip UnixArena1
root@Unixarena-SOL11:~# ifconfig UnixArena1
UnixArena1: flags=1000842 mtu 1500 index 8
inet 0.0.0.0 netmask 0
ether 2:8:20:de:13:31
root@Unixarena-SOL11:~#


4. Assign a IP address to VNIC. (Like a physical interface) and verfiy.

root@Unixarena-SOL11:~# ipadm create-addr -T static -a local=192.168.2.199/24 UnixArena1/primaryIP
root@Unixarena-SOL11:~# ifconfig UnixArena1
UnixArena1: flags=1000843 mtu 1500 index 8
inet 192.168.2.199 netmask ffffff00 broadcast 192.168.2.255
ether 2:8:20:de:13:31
root@Unixarena-SOL11:~# ipadm
NAME CLASS/TYPE STATE UNDER ADDR
UnixArena1 ip ok -- --
UnixArena1/primaryIP static ok -- 192.168.2.199/24
lo0 loopback ok -- --
lo0/v4 static ok -- 127.0.0.1/8
lo0/v6 static ok -- ::1/128
net0 ip ok -- --
net0/v4 static ok -- 192.168.2.51/24
net0/v6 addrconf ok -- fe80::20c:29ff:fe98:1da/10
net1 ip ok -- --
net1/WebIP static ok -- 192.168.2.200/24
root@Unixarena-SOL11:~#


5.Let me try to run snoop on VNIC which we have create now.

root@Unixarena-SOL11:~# snoop -d UnixArena1
Using device UnixArena1 (promiscuous mode)
192.168.2.75 -> 192.168.2.255 NBT NS Query Request for CGI[1c], Success
192.168.2.75 -> 192.168.2.255 NBT NS Query Request for CGI[1c], Success

192.168.2.75 -> Unixarena-SOL11 TCP D=22 S=53896 Ack=1465483610 Seq=3118040569 Len=0 Win=16367

The same way you can create a multiple VNIC and assign a new IP address to it.Hope you got some idea about Solaris 11 networking part which is completely different from Solaris 10.

Thank you for reading this article.
