Apply for EIP

• Apply for an EIP, which can be used to bind to any BCC instance
• Identity Verification is required for creation of EIP, if you fail to pass identity verification, you can go to identity verification under security authentication in [Baidu Open Cloud Console](https://console.bce.baidu.com/qualify/? =1567871861163#/qualify/result) for authentication.
• Billing class can be referred to Billing.

  public void createEip(EipClient eipClient, String name, int bandwidthInMbps, Billing billing) {
        CreateEipRequest createEipRequest = new CreateEipRequest();
        // Set name of created eip 
        createEipRequest.setName(name);
        // Set public network bandwidth, in Mbps 
        createEipRequest.setBandwidthInMbps(bandwidthInMbps);
        // Set order information 
        createEipRequest.setBilling(billing);
    
        CreateEipResponse createEipResponse = eipClient.createEip(createEipRequest);
    
        System.out.println(createEipResponse.getEip());
  }
  

Capacity Expansion and Reduction of EIP Bandwidth

• Used for the bandwidth capacity expansion and reduction of specified EIP
• Check whether EIP capacity expansion and reduction state is completed by querying EIP list

  public void resizeEip(EipClient eipClient, String eip��int bandwidthInMbps) {
        eipClient.resizeEip(eip, bandwidthInMbps);
  }
  

Bind EIP

• Bind EIP to an instance, and only BCC is supported currently.
• Only the EIP in available state supports binding operation.
• The bound instance cannot have any existing EIP binding relationship
• The bound instance cannot be in arrearage state.

  public void bindEip(EipClient eipClient, String eip, String instanceId, String instanceType) {
        eipClient.bindEip(eip, instanceId, instanceType);
  }
  

Unbind EIP

• Unbind the specified EIP
• The unbound EIP must have been bound to any instance.

  public void unbindEip(EipClient eipClient, String eip) {
        eipClient.unbindEip(eip);
  }
  

Release EIP

• Release the specified EIP, and the released EIP cannot be recovered.
• If EIP is bound to any instance, it can be released after unbinding.

  public void releaseEip(EipClient eipClient, String eip) {
        eipClient.releaseEip(eip);
  }

Query EIP List

• EIP list can be queried according to multiple conditions.
• If it is only needed to query the details of a single EIP, you only need to provide eip parameters.
• If you only need to query the EIP bound to a specified instance, you only need to provide instanceType parameter.
• If you only need to query the details of EIP bound to a specified instance, you only need to provide instanceType and instanceId parameter.
• If no query condition is provided, the default query overwrites all EIPs.
• The returned result is the query result of intersection of multiple conditions, i.e. when multiple conditions are provided, EIP meeting all conditions simultaneously is returned.
• The query result above supports marker paging, with paging size of 1,000 by default, which can be specified via maxKeys parameter.

public void listEips(EipClient eipClient, String eip) {
    ListEipsRequest listEipsRequest = new ListEipsRequest();
    listEipsRequest.setEip(eip);
    // Execute query list operation 
    ListEipsResponse listEipGroupResponse = eipClient.listEips(listEipsRequest);

    for (EipModel eipModel : listEipGroupResponse.getEipList()) {
        System.out.println(eipModel.getInstanceId());
    }
}

Renew EIP

• For the renewal operation of specified EIP, extend the expiration time
• No renewal operation can be conducted during EIP capacity expansion and reduction.

public void purchaseReservedEip(EipClient eipClient, String eip, int reservationLength, String reservationTimeUnit) {
    eipClient.purchaseReservedEip(eip, reservationLength, reservationTimeUnit);
}
