You can tag an EC2 Instance in multiple ways. This section describes the steps to tag an EC2 Instance manually.
To manually add a tag to an existing EC2 Instance
Select check box of the Instance that you want to tag.
Click Actions > Instance Settings > Add/Edit Tags.
Click Save to tag the Instance with entered key and value.
Verify the tag on the Instances page under the EC2 Dashboard.
With the Instance still selected, click the Tags tab to view the associated tags in the panel at the bottom of the page. This provides confirmation that the EC2 Instance has been tagged.
You can now use that tag while defining address object mappings in the SonicOS management interface.
