Chapter 3 IP over IB Protocol
Subinterfaces
Creating a Subinterface Associated with a Specific IB Partition
To create a subinterface associated with a specific IB partition, perform the following steps:
Step 1 Create a partition on an IB SFS. Alternatively, you can choose to create the partition of the IB interface
on the host first, and then create the partition for the ports on the IB SFS. See the Cisco SFS Product
Family Element Manager User Guide for information regarding valid partitions on the IB SFS.
Step 2 Log in to your host.
Step 3 Add the value of the partition key to the file as root user.
The following example shows how to add partition 80:02 to the primary interface ib0:
host1# /usr/local/topspin/sbin/ipoibcfg add ib0 80:02
Step 4 Verify that the interface is set up by ensuring that ib0.8002 is displayed.
The following example shows how to verify the interface:
host1# ls /sys/class/net
eth0 ib0 ib0.8002 ib1 lo sit0
Step 5 Verify that the interface was created by entering the ifconfig -a command.
The following example shows how to enter the ifconfig -a command:
host1# ifconfig -a
