Managing Subnet Tags

Scenarios

You can add tags to subnets to help you identify and organize them.

You can add a tag to a subnet when creating the subnet, or you can add a tag to a created subnet on the subnet details page. A maximum of 10 tags can be added to each subnet.

A tag consists of a key and value pair. Table 1 lists the tag key and value requirements.
