NetworkListenerProps
- class aws_cdk.aws_elasticloadbalancingv2.NetworkListenerProps(*, port, alpn_policy=None, certificates=None, default_action=None, default_target_groups=None, protocol=None, ssl_policy=None, load_balancer)
Bases:
BaseNetworkListenerProps
Properties for a Network Listener attached to a Load Balancer.
- Parameters
port (
Union
[int
,float
]) – The port on which the listener listens for requests.alpn_policy (
Optional
[AlpnPolicy
]) – Application-Layer Protocol Negotiation (ALPN) is a TLS extension that is sent on the initial TLS handshake hello messages. ALPN enables the application layer to negotiate which protocols should be used over a secure connection, such as HTTP/1 and HTTP/2. Can only be specified together with Protocol TLS. Default: - Nonecertificates (
Optional
[Sequence
[IListenerCertificate
]]) – Certificate list of ACM cert ARNs. You must provide exactly one certificate if the listener protocol is HTTPS or TLS. Default: - No certificates.default_action (
Optional
[NetworkListenerAction
]) – Default action to take for requests to this listener. This allows full control of the default Action of the load balancer, including weighted forwarding. See theNetworkListenerAction
class for all options. Cannot be specified together withdefaultTargetGroups
. Default: - None.default_target_groups (
Optional
[Sequence
[INetworkTargetGroup
]]) – Default target groups to load balance to. All target groups will be load balanced to with equal weight and without stickiness. For a more complex configuration than that, use eitherdefaultAction
oraddAction()
. Cannot be specified together withdefaultAction
. Default: - None.protocol (
Optional
[Protocol
]) – Protocol for listener, expects TCP, TLS, UDP, or TCP_UDP. Default: - TLS if certificates are provided. TCP otherwise.ssl_policy (
Optional
[SslPolicy
]) – SSL Policy. Default: - Current predefined security policy.load_balancer (
INetworkLoadBalancer
) – The load balancer to attach this listener to.

Attributes
- alpn_policy
Application-Layer Protocol Negotiation (ALPN) is a TLS extension that is sent on the initial TLS handshake hello messages.
ALPN enables the application layer to negotiate which protocols should be used over a secure connection, such as HTTP/1 and HTTP/2.
Can only be specified together with Protocol TLS.
- Default
None
- certificates
Certificate list of ACM cert ARNs.
You must provide exactly one certificate if the listener protocol is HTTPS or TLS.
- Default
No certificates.
- default_action
Default action to take for requests to this listener.
This allows full control of the default Action of the load balancer, including weighted forwarding. See the
NetworkListenerAction
class for all options.Cannot be specified together with
defaultTargetGroups
.- Default
None.
- default_target_groups
Default target groups to load balance to.
All target groups will be load balanced to with equal weight and without stickiness. For a more complex configuration than that, use either
defaultAction
oraddAction()
.Cannot be specified together with
defaultAction
.- Default
None.
- load_balancer
The load balancer to attach this listener to.
- port
The port on which the listener listens for requests.
- protocol
Protocol for listener, expects TCP, TLS, UDP, or TCP_UDP.
- Default
TLS if certificates are provided. TCP otherwise.
- ssl_policy
SSL Policy.
- Default
Current predefined security policy.
