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.

  public function createEip($eipClient, $name, $bandwidthInMbps, $billing) {
        $result = $eipClient->createEip($bandwidthInMbps, $name, $billing);
        echo $result->id;
  }
  

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 function resizeEip($eipClient, $eip, $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 function bindEip($eipClient, $eip, $instanceId, $instanceType) {
        $eipClient->bindEip($eip, $instanceId, $instanceType);
  } 

Unbind EIP

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

  public function unbindEip($eipClient, $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 function releaseEip($eipClient, $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 function listEips($eipClient, $eip) {
    $result = $eipClient->listEips($eip);
    var_dump($result);
}

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 function purchaseReservedEip($eipClient, $billing, $eip) {
    $result = $eipClient->purchaseReservedEip($eip,$billing);
    var_dump($result);
}
