Managing Subnet Tags

Scenarios

A subnet tag identifies a subnet. Tags can be added to subnets to facilitate subnet identification and administration. 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 20 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.
