Assigning a Shared Bandwidth


When you host a large number of applications on the cloud, if each EIP uses dedicated bandwidth, a lot of bandwidths are required, which incurs high costs. If all EIPs share the same bandwidth, your network operation costs will be lowered and your system O&M as well as resource statistics will be simplified.

Assign a shared bandwidth for use with EIPs.


  1. Log in to the management console.
  2. Click in the upper left corner and choose Networking > Elastic IP.
  3. In the navigation pane on the left, choose Elastic IP and Bandwidth > Shared Bandwidths.
  4. In the upper right corner, click Buy Shared Bandwidth. On the displayed page, configure parameters as prompted.

    Table 1 Parameter descriptions



    Example Value

    Billing Mode

    A shared bandwidth can be billed on a yearly/monthly or pay-per-use basis.

    • Yearly/Monthly: You pay for the bandwidth by year or month before using it. No other charges apply during the validity period of the bandwidth.
    • Pay-per-use: You pay for the bandwidth based on the amount of time you use the bandwidth.



    Regions are geographic areas that are physically isolated from each other. The networks inside different regions are not connected to each other, so resources cannot be shared across different regions. For lower network latency and faster access to your resources, select the region nearest you.


    Bandwidth Type

    Select a type of the shared bandwidth based on your EIP type.

    • Standard: Dynamic BGP and premium BGP EIPs can be added to a shared bandwidth of this type.

    In the CN-Hong Kong region, only dynamic BGP EIPs can be added to standard shared bandwidths.


    Billed By

    The billing method for the shared bandwidth.

    You can specify a shared bandwidth to be billed by bandwidth.



    The bandwidth size in Mbit/s.


    Enterprise Project

    The enterprise project that the EIP belongs to.

    An enterprise project facilitates project-level management and grouping of cloud resources and users. The name of the default project is default.



    The name of the shared bandwidth.


    Required Duration

    The duration for which the purchased EIP will use. The duration must be specified if the Billing Mode is set to Yearly/Monthly.
