DESCRIPTION

       This object provides access to information about Amazon Elastic Network Interface objects,
       which are used in conjunction with virtual private cloud (VPC) instances to create multi-
       homed web servers, routers, firewalls, and so forth.

       Please see VM::EC2::Generic for methods shared by all VM::EC2 objects.

METHODS

       These object methods are supported:

        networkInterfaceId       -- The ID of this ENI
        subnetId                 -- The ID of the subnet this ENI belongs to
        vpcId                    -- The ID of the VPC this ENI belongs to
        ownerId                  -- Owner of the ENI
        status                   -- ENI status, one of "available" or "in-use"
        privateIpAddress         -- Primary private IP address of the ENI
        privateDnsName           -- Primary private DNS name of the ENI
                                    as a set of VM::EC2::Group objects.
        attachment               -- Information about the attachment of this ENI to
                                    an instance, as a VM::EC2::NetworkInterface::Attachment
                                    object.
        association              -- Information about the association of this ENI with
                                    an elastic public IP address.
        privateIpAddresses       -- List of private IP addresses assigned to this ENI,
                                    as a list of VM::EC2::NetworkInterface::PrivateIpAddress
                                    objects.
        availabilityZone         -- Availability zone for this ENI as a VM::EC2::AvailabilityZone
                                    object.
        macAddress               -- MAC address for this interface.

       In addition, this object supports the following convenience methods:

        resetAttributes()          -- Return attributes to their default states. Currently only
                                      sets the SourceDestCheck value to true.

        description([$new_value])  -- Description of the ENI. Pass a single argument to set a new
                                      description

        sourceDestCheck([$boolean])-- Boolean value. If true, prevent this ENI from
                                      forwarding packets between subnets. Value can optionally
                                      be set

        security_groups([@new_groups]) -- List of security groups this ENI belongs to. Pass a
                                      list of new security groups to change this value.

        delete_on_termination([$boolean])
                                   -- Whether the deleteOnTermination flag is set for the current
                                      attachment. Pass a boolean value to change the value.

Attaching to an instance

       The following methods allow the interface to be attached to, and detached from, instances.

   $attachment_id = $interface->attach($instance_id => $device)
   $attachment_id = $interfacee->attach(-instance_id    => $id, -device_index   => $device)
       This method attaches the network interface an instance using the the indicated device
       index. You can provide either an instance ID, or a VM::EC2::Instance object. You may use
       an integer for -device_index, or use the strings "eth0", "eth1" etc.

       Required arguments:

        -instance_id          ID of the instance to attach to.
        -device_index         Network device number to use (e.g. 0 for eth0).

       On success, this method returns the attachmentId of the new attachment (not a
       VM::EC2::NetworkInterface::Attachment object, due to an AWS API inconsistency).

   $boolean = $interface->detach([$force])
       This method detaches the network interface from whatever instance it is currently attached
       to. If a true argument is provided, then the detachment will be forced, even if the
       interface is in use.

       On success, this method returns a true value.

Adding IP addresses

   $result = $interface->assign_private_ip_addresses(@addresses)
   $result = $interface->assign_private_ip_addresses(%args)
       Assign one or more secondary private IP addresses to the network interface. You can either
       set the addresses explicitly, or provide a count of secondary addresses, and let Amazon
       select them for you.

       In the list argument form, pass a list of desired IP addresses, or a count of the number
       of addresses to select for you:

        $interface->assign_private_ip_addresses(3);  # three automatic addresses
        $interface->assign_private_ip_addresses('192.168.0.10','192.168.0.11');

       Required arguments:

        -private_ip_address      One or more secondary IP addresses, as a scalar string
        -private_ip_addresses    or array reference. (The two arguments are equivalent).

       Optional arguments:

        -allow_reassignment      If true, allow assignment of an IP address is already in
                                 use by another network interface or instance.

       The following are valid arguments to -private_ip_address:

        -private_ip_address => '192.168.0.12'                    # single address
        -private_ip_address => ['192.168.0.12','192.168.0.13]    # multiple addresses
        -private_ip_address => 3                                 # autoselect three addresses

       The mixed form of address, such as ['192.168.0.12','auto'] is not allowed in this call.

       On success, this method returns true.

   $result = $interface->unassign_private_ip_addresses(@addresses)
   $result = $interface->unassign_private_ip_addresses(-private_ip_address => \@addresses)
       Unassign one or more secondary private IP addresses from the network interface.

       In the list argument form, pass a list of desired IP addresses to unassign.

        $interface->assign_private_ip_addresses('192.168.0.10','192.168.0.11');

       In the named argument form, use:

        -private_ip_address      One or more secondary IP addresses, as a scalar string
        -private_ip_addresses    or array reference. (The two arguments are equivalent).

       The following are valid arguments to -private_ip_address:

        -private_ip_address => '192.168.0.12'                    # single address
        -private_ip_address => ['192.168.0.12','192.168.0.13]    # multiple addresses

       On success, this method returns true.

STRING OVERLOADING

       When used in a string context, this object will be interpolated as the networkInterfaceId
