Last updated: 2025-03-14 17:44:08

This document describes how to adjust the specification of LCU-supported CLBs. For more information about specifications, see Instance Specifications Comparison.
Note:
If the selected specification is lower than the existing specification, the new specification may not meet the business requirements, which may bring packet loss due to rate limiting.
For pay-as-you-go LCU-supported CLBs, the selected specification is the maximum speed limit, and the LCU unit price remains unchanged.
Directions
1. Log in to the CLB console and click Instance management in the left sidebar.
2. On the Instance management page, select a region in the top-left corner. Locate the target instance in the instance list, and choose More > Adjust specification under Operation.
﻿
Click an LCU-supported CLB to open the Basic information page, and select Billing information > Instance specification > Adjust specification.
﻿
3. In the Adjust specification window, set the target specification, and click Confirm.
Note：
1. If the bandwidth limit of the selected target specification is lower than the current bandwidth limit, adjust the current bandwidth limit first, or select another specification.
2. If the selected target specification is lower than the existing one, there is a risk that the downgraded specification cannot meet business needs well. This may cause packet loss due to speed limitation and affect your business. Please confirm the adjustment operation once again.
