Verify that you see the ib0.8002 output.
Step 6
Configure the new interface just as you would the parent interface. (See the 
.)
The following example shows how to configure the new interface:
host1# ifconfig ib0.8002 192.168.12.1 netmask 255.255.255.0
Removing a Subinterface Associated with a Specific IB Partition
To remove a subinterface, perform the following steps: 
Step 1
Take the subinterface offline. You cannot remove a subinterface until you bring it down.
The following example shows how to take the subinterface offline:
 
host1# ifconfig ib0.8002 down
Step 2
Remove the value of the partition key to the file as root user.
The following example shows how to remove the partition 80:02 from the primary interface ib0: 
host1# /usr/local/topspin/sbin/ipoibcfg del ib0 80:02
Step 3
(Optional) Verify that the subinterface no longer appears in the interface list by entering the ifconfig -a 
command.
The following example shows how to verify that the subinterface no longer appears in the interface list:
host1# ifconfig -a
