Managing Subnet Tags

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

You can add tags when creating a subnet or add tags to existing subnets.

Each cloud resource can have a maximum of 20 tags.

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