# DescribeCloudAvailableBandwidthTiers

## 1. API Description

This API (DescribeCloudAvailableBandwidthTiers) is used to query Cloud Connect Available Bandwidth Tiers

{% hint style="info" %}
**Notes**

* When modifying the Cloud Connect bandwidth limit, use the cloudPortId parameter to query the available bandwidth tiers for the target Cloud Connect.
* An empty result means there is currently no available bandwidth for the Cloud Connect.
