Why Does the CBH Traffic Bandwidth Exceed the Threshold?

Symptoms

An error is reported indicating that the traffic bandwidth exceeds the threshold. As a result, the CBH system cannot be used and managed resources cannot be accessed through CBH.

Possible Causes

The traffic bandwidth used by CBH exceeds the maximum shared bandwidth or dedicated bandwidth of the bound EIP.

Solution

  1. Locate the cause of the EIP bandwidth restriction. For details, see How Do I Know If My EIP Bandwidth Has Been Exceeded?
  2. Reconfigure the bandwidth of the EIP bound to the CBH instance. A bandwidth larger than 5 Mbit/s is recommended. For details, see VPC Shared Bandwidth Overview.
