4.
Select the appropriate radio button to export either the coni guration of the distributed
switch and all the distributed ports groups or just the coni guration of the distributed
switch.
5.
Optionally, supply a description of the exported (saved) coni guration, then click OK.
6.
When prompted if you want to save the exported coni guration i le, click Yes.
7.
Use your operating system's File Save dialog box to select the location where the exported
coni guration i le (named backup.zip) should be saved.
Once you have the coni guration exported to a i le, you can then import this coni guration
back into your vSphere environment at a later date to restore the saved coni guration. You can
also import the coni guration into a different vSphere environment, such as an environment
being managed by a separate vCenter Server instance.
To import a saved coni guration, perform these steps:
1.
Log into a vCenter Server instance using the vSphere Web Client.
2.
Navigate to the distributed switch whose coni guration you'd like to restore.
➢
3.
From the Actions menu, select All vCenter Actions
Restore Coni guration. This opens
the Restore Coni guration wizard.
4.
Use the Browse button to select the saved coni guration i le created earlier by exporting
the coni guration.
5.
Select the appropriate radio button to restore either the distributed switch and all distrib-
uted port groups or just the distributed switch coni guration.
6.
Note that if vSphere automatically saved a previous version of the coni guration (to pro-
tect against loss of management connectivity), this dialog box will also have the option
of restoring the previous coni guration. In this case, you do not need to select the saved
backup i le.
7.
Click Next.
8.
Review the settings that the wizard will import. If everything is correct, click Finish; oth-
erwise, use Back to go back and make changes.
Both vSphere Network Rollback and the ability to manually export or import the coni gu-
ration of a distributed switch are major steps forward in managing distributed switches in a
vSphere environment.
Most of the work that a VMware administrator needs to perform will revolve around distrib-
uted port groups, so let's turn our attention to working with them.
Working With Distributed Port Groups
With vSphere Standard Switches, port groups are the key to connectivity for the VMkernel and
for VMs. Without ports and port groups on a vSwitch, nothing can be connected to that vSwitch.
The same is true for vSphere Distributed Switches. Without a distributed port group, nothing
can be connected to a distributed switch, and the distributed switch is, therefore, unusable. In
the following sections, you'll take a closer look at creating, coni guring, and removing distrib-
uted port groups.
