# View the state of a Capacity Reservation
<a name="capacity-reservations-view"></a>

Amazon EC2 constantly monitors the state of your Capacity Reservations.

Due to the [eventual consistency](https://docs.amazonaws.cn/ec2/latest/devguide/eventual-consistency.html) model followed by the Amazon EC2 API, after you create a Capacity Reservation, it can take up to 5 minutes for the state of the Capacity Reservation to reflect that it is `active`. During this time, the Capacity Reservation might remain in the `pending` state. However, it might already be available for use, in which case attempts to launch instances into the Capacity Reservation would succeed.

------
#### [ Console ]

**To view your Capacity Reservations**

1. Open the Amazon EC2 console at [https://console.amazonaws.cn/ec2/](https://console.amazonaws.cn/ec2/).

#### [ Amazon CLI ]

**To describe your Capacity Reservations**
