Managing NAT Gateway Tags

Scenarios

A NAT gateway tag identifies the NAT gateway. Tags can be added to NAT gateways to ease NAT gateway identification and administration. You can add a tag to a NAT gateway when creating the NAT gateway. Alternatively, you can add a tag to a created NAT gateway on the NAT gateway details page. A maximum of ten tags can be added to each NAT gateway.

Only public NAT gateways support tag management.

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