Updated at：2025-10-16
Description

- For cross-account scenarios, only the initiator can perform bandwidth resizing;
- Prepay peering connections can only be subject to bandwidth scaling up, rather than scaling down;
- Postpay peering connections can be subject to both bandwidth scaling up and scaling down;
