21 This object provides access to information about Amazon Elastic Network
22 Interface objects, which are used in conjunction with virtual private
23 cloud (VPC) instances to create multi-homed web servers, routers,
24 firewalls, and so forth.
25 Please see VM::EC2::Generic for methods shared by all VM::EC2 objects.
27
29 These object methods are supported:
30 networkInterfaceId -- The ID of this ENI
32 subnetId -- The ID of the subnet this ENI belongs to
33 vpcId -- The ID of the VPC this ENI belongs to
34 ownerId -- Owner of the ENI
35 status -- ENI status, one of "available" or "in-use"
36 privateIpAddress -- Primary private IP address of the ENI
37 privateDnsName -- Primary private DNS name of the ENI
38 as a set of VM::EC2::Group objects.
39 attachment -- Information about the attachment of this ENI to
40 an instance, as a VM::EC2::NetworkInterface::Attachment
41 object.
42 association -- Information about the association of this ENI with
43 an elastic public IP address.
44 privateIpAddresses -- List of private IP addresses assigned to this ENI,
45 as a list of VM::EC2::NetworkInterface::PrivateIpAddress
46 objects.
47 availabilityZone -- Availability zone for this ENI as a VM::EC2::AvailabilityZone
48 object.
49 macAddress -- MAC address for this interface.
50 In addition, this object supports the following convenience methods:
52 resetAttributes() -- Return attributes to their default states. Currently only
54 sets the SourceDestCheck value to true.
55 description([$new_value]) -- Description of the ENI. Pass a single argument to set a new
57 description
58 sourceDestCheck([$boolean])-- Boolean value. If true, prevent this ENI from
60 forwarding packets between subnets. Value can optionally
61 be set
62 security_groups([@new_groups]) -- List of security groups this ENI belongs to. Pass a
64 list of new security groups to change this value.
65 delete_on_termination([$boolean])
67 -- Whether the deleteOnTermination flag is set for the current
68 attachment. Pass a boolean value to change the value.
69
71 The following methods allow the interface to be attached to, and
72 detached from, instances.
73 $attachment_id = $interface->attach($instance_id => $device)
75 $attachment_id = $interfacee->attach(-instance_id => $id, -device_index
76 => $device)
77 This method attaches the network interface an instance using the the
78 indicated device index. You can provide either an instance ID, or a
79 VM::EC2::Instance object. You may use an integer for -device_index, or
80 use the strings "eth0", "eth1" etc.
81 Required arguments:
83 -instance_id ID of the instance to attach to.
85 -device_index Network device number to use (e.g. 0 for eth0).
86 On success, this method returns the attachmentId of the new attachment
88 (not a VM::EC2::NetworkInterface::Attachment object, due to an AWS API
89 inconsistency).
90 $boolean = $interface->detach([$force])
92 This method detaches the network interface from whatever instance it is
93 currently attached to. If a true argument is provided, then the
94 detachment will be forced, even if the interface is in use.
95 On success, this method returns a true value.
97
99 $result = $interface->assign_private_ip_addresses(@addresses)
100 $result = $interface->assign_private_ip_addresses(%args)
101 Assign one or more secondary private IP addresses to the network
102 interface. You can either set the addresses explicitly, or provide a
103 count of secondary addresses, and let Amazon select them for you.
104 In the list argument form, pass a list of desired IP addresses, or a
106 count of the number of addresses to select for you:
107 $interface->assign_private_ip_addresses(3); # three automatic addresses
109 $interface->assign_private_ip_addresses('192.168.0.10','192.168.0.11');
110 Required arguments:
112 -private_ip_address One or more secondary IP addresses, as a scalar string
114 -private_ip_addresses or array reference. (The two arguments are equivalent).
115 Optional arguments:
117 -allow_reassignment If true, allow assignment of an IP address is already in
119 use by another network interface or instance.
120 The following are valid arguments to -private_ip_address:
122 -private_ip_address => '192.168.0.12' # single address
124 -private_ip_address => ['192.168.0.12','192.168.0.13] # multiple addresses
125 -private_ip_address => 3 # autoselect three addresses
126 The mixed form of address, such as ['192.168.0.12','auto'] is not
128 allowed in this call.
129 On success, this method returns true.
131 $result = $interface->unassign_private_ip_addresses(@addresses)
133 $result = $interface->unassign_private_ip_addresses(-private_ip_address =>
134 \@addresses)
135 Unassign one or more secondary private IP addresses from the network
136 interface.
137 In the list argument form, pass a list of desired IP addresses to
139 unassign.
140 $interface->assign_private_ip_addresses('192.168.0.10','192.168.0.11');
142 In the named argument form, use:
144 -private_ip_address One or more secondary IP addresses, as a scalar string
146 -private_ip_addresses or array reference. (The two arguments are equivalent).
147 The following are valid arguments to -private_ip_address:
149 -private_ip_address => '192.168.0.12' # single address
151 -private_ip_address => ['192.168.0.12','192.168.0.13] # multiple addresses
152 On success, this method returns true.
154
156 When used in a string context, this object will be interpolated as the
157 networkInterfaceId
