Network Configuration Profile
Solaris 11 uses profile-based network configuration. It has 2 configuration modes :
1. Automatic – Uses DHCP to obtain network configuration (IP address, router and DNS) from any of the connected ethernet interfaces. Do not support hot swapping of interfaces and IPMP.
2. Manual (DefaultFixed NCP) – interfaces needs to be manually configured using dladm and ipadm commands. Also called as DefaultFixed NCP. Supports hot swapping of interfaces and IPMP.
Configuring the IP address
Step 1 : Set the NCP
We would set the NCP to DefaultFixed profile in order to configure the IP address manually.
To check the current NCP setting:
# netadm list TYPE PROFILE STATE ncp Automatic disabled ncp DefaultFixed online loc Automatic offline loc NoNet offline loc DefaultFixed online
As seen in the output above, the NCP is set to DefaultFixed. In case it is not set, use netadm command to set it to DefaultFixed :
# netadm enable -p ncp DefaultFixed
Step 2 : Check the link status
The command “dladm show-dev” does not work in Solaris 11. The command to check the link status in Solaris 11 is :
# dladm show-phys LINK MEDIA STATE SPEED DUPLEX DEVICE net0 Ethernet up 1000 full e1000g0
Now if you see, there is a device alias name net0 for e1000g0. Starting Solaris 11, all the network ports would be identified by an alias in a generic format of net#.
Step 3 : Create a new interface
The ipadm command creates the new interface to be configured :
# ipadm create-ip net0
Check the newly created interface :
# ipadm show-if IFNAME CLASS STATE ACTIVE OVER lo0 loopback ok yes --- net0 ip down no ---
Step 4 : Creating IP address
# ipadm create-addr –T static –a local=192.168.1.10/24 net0/wan
-T specifies either static, dhcp or addrconf (for IPv6) types of addresses. The string wan can be any random string used to identify the interface.
To check the interface status of the interface :
# ipadm show-if IFNAME CLASS STATE ACTIVE OVER lo0 loopback ok yes -- net0 ip ok yes --
To check the configured IP address :
# ipadm show-addr ADDROBJ TYPE STATE ADDR lo0/v4 static ok 127.0.0.1/8 net0/wan static ok 192.168.1.20/24 lo0/v6 static ok ::1/128
Delete the interface / Unplumb
In Solaris 11, If we want to unplumb the interface, we have to delete it. Also, even in case you want to change the IP address of the interface, you have to delete it first and then re-create it to assign the IP address it.
# ipadm delete-ip net0
