# Change Bandwidth

{% hint style="info" %} <mark style="color:blue;">**Note**</mark>

<mark style="color:blue;">Both links of an HA instance must maintain the same bandwidth specification. Bandwidth changes apply to both links simultaneously; setting different values for each link is not supported.</mark>
{% endhint %}

## Procedures

You can initiate a bandwidth change from either of the following locations:

* **List page**: Hover over the instance row → **Actions** → **Change Bandwidth**
* **Details page**: Go to instance details → **Information** → **Network Bandwidth Configuration** → **Change Bandwidth**

Enter the new bandwidth value in the dialog and click **Confirm** to submit.

{% hint style="info" %} <mark style="color:blue;">**Note**</mark>

<mark style="color:blue;">If the change fails on either link, the system automatically rolls back and restores the original bandwidth.</mark>
