Module: Google::Cloud::NetworkManagement::V1::Step::State

Defined in:

proto_docs/google/cloud/networkmanagement/v1/trace.rb

Overview

Type of states that are defined in the network state machine. Each step in the packet trace is in a specific state.

Constant Summary

STATE_UNSPECIFIED =

Unspecified state.

0

START_FROM_INSTANCE =

Initial state: packet originating from a Compute Engine instance. An InstanceInfo is populated with starting instance information.

1

START_FROM_INTERNET =

Initial state: packet originating from the internet. The endpoint information is populated.

2

START_FROM_GOOGLE_SERVICE =

Initial state: packet originating from a Google service. Some Google services, such as health check probers or Identity Aware Proxy use special routes, outside VPC routing configuration to reach Compute Engine Instances.

27

START_FROM_PRIVATE_NETWORK =

Initial state: packet originating from a VPC or on-premises network with internal source IP. If the source is a VPC network visible to the user, a NetworkInfo is populated with details of the network.

3

START_FROM_GKE_MASTER =

Initial state: packet originating from a Google Kubernetes Engine cluster master. A GKEMasterInfo is populated with starting instance information.

21

START_FROM_CLOUD_SQL_INSTANCE =

Initial state: packet originating from a Cloud SQL instance. A CloudSQLInstanceInfo is populated with starting instance information.

22

START_FROM_CLOUD_FUNCTION =

Initial state: packet originating from a Cloud Function. A CloudFunctionInfo is populated with starting function information.

23

START_FROM_APP_ENGINE_VERSION =

Initial state: packet originating from an App Engine service version. An AppEngineVersionInfo is populated with starting version information.

25

START_FROM_CLOUD_RUN_REVISION =

Initial state: packet originating from a Cloud Run revision. A CloudRunRevisionInfo is populated with starting revision information.

26

APPLY_INGRESS_FIREWALL_RULE =

Config checking state: verify ingress firewall rule.

4

APPLY_EGRESS_FIREWALL_RULE =

Config checking state: verify egress firewall rule.

5

APPLY_ROUTE =

Config checking state: verify route.

6

APPLY_FORWARDING_RULE =

Config checking state: match forwarding rule.

7

SPOOFING_APPROVED =

Config checking state: packet sent or received under foreign IP address and allowed.

8

ARRIVE_AT_INSTANCE =

Forwarding state: arriving at a Compute Engine instance.

9

ARRIVE_AT_INTERNAL_LOAD_BALANCER =

Forwarding state: arriving at a Compute Engine internal load balancer.

10

ARRIVE_AT_EXTERNAL_LOAD_BALANCER =

Forwarding state: arriving at a Compute Engine external load balancer.

11

ARRIVE_AT_VPN_GATEWAY =

Forwarding state: arriving at a Cloud VPN gateway.

12

ARRIVE_AT_VPN_TUNNEL =

Forwarding state: arriving at a Cloud VPN tunnel.

13

ARRIVE_AT_VPC_CONNECTOR =

Forwarding state: arriving at a VPC connector.

24

NAT =

Transition state: packet header translated.

14

PROXY_CONNECTION =

Transition state: original connection is terminated and a new proxied connection is initiated.

15

DELIVER =

Final state: packet could be delivered.

16

DROP =

Final state: packet could be dropped.

17

FORWARD =

Final state: packet could be forwarded to a network with an unknown configuration.

18

ABORT =

Final state: analysis is aborted.

19

VIEWER_PERMISSION_MISSING =

Special state: viewer of the test result does not have permission to see the configuration in this step.
