a time) and make sure pings continue to work, regardless of if we have either cable

plugged in, or both cables plugged in.

In Example 7-11, we lost a total of three pings while pulling and adding cables. Ping

packet 9 was lost when we pulled the first cable, ping packets 21 and 22 were lost when

we reinserted the first cable and pulled the second cable.

Example 7-11 InfiniBand host pinging the default gateway while cables being pulled and re-added

7.5.4 CLI reference for this section

This section includes what the appropriate CLI looks like after the steps were executed in the

GUI to create TG1, as well as after the changes made to the 4948. It is a useful reference for

those wanting to understand the CLI better, or for those that simply want to use the CLI and

not the GUI to achieve this task.

Note that we only include the commands that effect the area of the device we configured. We

do not include the entire device configuration.
