# CreateQosPolicyGroup

## 1. API Description

This API (CreateQosPolicyGroup) is used to create a QoS policy group to apply shared bandwidth rate limiting to EIPs, IPv6 addresses, or UNMANAGED egress IPs within the same group.

{% hint style="info" %}
**Bandwidth Limit**

* The minimum bandwidth limit is 10,000 Mbps (10G) by default.
* If you need a bandwidth limit lower than 10G, please contact [Zenlayer Support](https://www.zenlayer.com/support/).
  {% endhint %}
