Binding an EIP to a CBH Instance

An EIP must be bound to a CBH instance if you want to perform any of the following operations (the minimum EIP bandwidth is 5 Mbit/s):

  • Log in to the CBH system using a web browser. URL: https:// EIP of the CBH instance, for example, https://10.10.10.10.
  • If the mobile SMS login is configured, you need to obtain the verification code through the mobile phone. If the EIP is not configured, you cannot receive SMS messages.
  • Interconnect with LTS to send logs. For details, see Configuring LTS.
  • In V3.3.2.0 and earlier versions, if no EIPs are bound to a CBH instance, operations such as changing the version specifications, upgrading the version, and starting or restarting the instance will fail.

Constraints

When binding an EIP to a CBH instance, the operation can be done on the CBH console only. Otherwise, you cannot log in to the CBH instance using IAM.

Prerequisites

  • You have purchased at least one elastic IP address (EIP).
    • An EIP can be bound to only one cloud resource. A CBH instance cannot share an EIP with other cloud resources.
    • The same account must be used to purchase CBH instances and EIPs to be bound to them, and the instances and EIPs must be in the same region.

Procedure

  1. Log in to the management console.
  2. Locate the row containing the instance to which you want to bind an EIP. In the Operation column, choose More > Configure Network > Bind EIP.
  3. In the displayed dialog box, select an EIP in the Unbound status and click OK.

    After the binding is successful, the Login button will be enabled. You can check the bound EIP in the EIP column.

    If no EIPs are available, create one. For details, see EIP Overview.
