Reference documentation and code samples for the Network Management v1 API enum DropInfo.Types.Cause.

Drop cause types:

Namespace

Google.Cloud.NetworkManagement.V1

Assembly

Google.Cloud.NetworkManagement.V1.dll

Fields

NameDescription
CloudFunctionNotActive

Packet could be dropped because the Cloud Function is not in an active status.

CloudNatNoAddresses

Packet sent to Cloud Nat without active NAT IPs.

CloudRunRevisionNotReady

Packet sent from a Cloud Run revision that is not ready.

CloudSqlInstanceNoIpAddress

Packet was dropped because the Cloud SQL instance has neither a private nor a public IP address.

CloudSqlInstanceNoRoute

Packet was dropped because there is no route from a Cloud SQL instance to a destination network.

CloudSqlInstanceNotConfiguredForExternalTraffic

Packet sent from a Cloud SQL instance to an external IP address is not allowed. The Cloud SQL instance is not configured to send packets to external IP addresses.

CloudSqlInstanceNotRunning

Packet sent from or to a Cloud SQL instance that is not in running state.

CloudSqlInstanceUnauthorizedAccess

Access to the Cloud SQL instance endpoint is not authorized. See Authorizing with authorized networks for more details.

CloudSqlPscNegUnsupported

The packet is sent to the Private Service Connect backend (network endpoint group) targeting a Cloud SQL service attachment, but this configuration is not supported.

DroppedInsideCloudSqlService

Packet was dropped inside Cloud SQL Service.

DroppedInsideGkeService

Packet was dropped inside Google Kubernetes Engine Service.

DroppedInsidePscServiceProducer

Packet was dropped inside Private Service Connect service producer.

FirewallBlockingLoadBalancerBackendHealthCheck

Firewalls block the health check probes to the backends and cause the backends to be unavailable for traffic from the load balancer. For more details, see Health check firewall rules.

FirewallRule

Dropped due to a firewall rule, unless allowed due to connection tracking.

ForeignIpDisallowed

A Compute Engine instance can only send or receive a packet with a foreign IP address if ip_forward is enabled.

ForwardingRuleMismatch

Forwarding rule's protocol and ports do not match the packet header.

ForwardingRuleNoInstances

Forwarding rule does not have backends configured.

ForwardingRuleRegionMismatch

Packet could be dropped because it was sent from a different region to a regional forwarding without global access.

GkeClusterNotRunning

Packet sent from or to a GKE cluster that is not in running state.

GkeControlPlaneNoRoute

Packet was dropped because there is no route from a GKE cluster control plane to a destination network.

GkeControlPlaneRegionMismatch

Packet was dropped because a GKE cluster private endpoint is unreachable from a region different from the cluster's region.

GkeMasterUnauthorizedAccess

Access to Google Kubernetes Engine cluster master's endpoint is not authorized. See Access to the cluster endpoints for more details.

GkePscEndpointMissing

Packet was dropped because the GKE cluster uses Private Service Connect (PSC), but the PSC endpoint is not found in the project.

GoogleManagedServiceNoPeering

Packet was dropped because there is no peering between the originating network and the Google Managed Services Network.

GoogleManagedServiceNoPscEndpoint

Packet was dropped because the Google-managed service uses Private Service Connect (PSC), but the PSC endpoint is not found in the project.

HybridNegNonDynamicRouteMatched

The packet sent from the hybrid NEG proxy matches a non-dynamic route, but such a configuration is not supported.

HybridNegNonLocalDynamicRouteMatched

The packet sent from the hybrid NEG proxy matches a dynamic route with a next hop in a different region, but such a configuration is not supported.

InstanceNotRunning

Packet is sent from or to a Compute Engine instance that is not in a running state.

LoadBalancerHasNoProxySubnet

Packet sent to a load balancer, which requires a proxy-only subnet and the subnet is not found.

NoExternalAddress

Instance with only an internal IP address tries to access external hosts, but Cloud NAT is not enabled in the subnet, unless special configurations on a VM allow this connection.

NoNatSubnetsForPscServiceAttachment

No NAT subnets are defined for the PSC service attachment.

NoRoute

Dropped due to no matching routes.

NoRouteFromInternetToPrivateIpv6Address

Packet is sent from the Internet to the private IPv6 address.

PrivateGoogleAccessDisallowed

Instance with only an internal IP address tries to access Google API and services, but private Google access is not enabled in the subnet.

PrivateGoogleAccessViaVpnTunnelUnsupported

Source endpoint tries to access Google API and services through the VPN tunnel to another network, but Private Google Access needs to be enabled in the source endpoint network.

PrivateTrafficToInternet

Packet with internal destination address sent to the internet gateway.

PscConnectionNotAccepted

The Private Service Connect endpoint is in a project that is not approved to connect to the service.

PscEndpointAccessedFromPeeredNetwork

The packet is sent to the Private Service Connect endpoint over the peering, but it's not supported.

PscNegProducerEndpointNoGlobalAccess

The packet is sent to the Private Service Connect backend (network endpoint group), but the producer PSC forwarding rule does not have global access enabled.

PscNegProducerForwardingRuleMultiplePorts

The packet is sent to the Private Service Connect backend (network endpoint group), but the producer PSC forwarding rule has multiple ports specified.

PublicCloudSqlInstanceToPrivateDestination

Packet sent from a Cloud SQL instance with only a public IP address to a private IP address.

PublicGkeControlPlaneToPrivateDestination

Packet sent from a public GKE cluster control plane to a private IP address.

RouteBlackhole

Dropped due to invalid route. Route's next hop is a blackhole.

RouteNextHopForwardingRuleIpMismatch

Route's next hop forwarding rule doesn't match next hop IP address.

RouteNextHopForwardingRuleTypeInvalid

Route's next hop forwarding rule type is invalid (it's not a forwarding rule of the internal passthrough load balancer).

RouteNextHopInstanceNonPrimaryIp

Route's next hop IP address is not a primary IP address of the next hop instance.

RouteNextHopInstanceWrongNetwork

Route's next hop instance doesn't hace a NIC in the route's network.

RouteNextHopIpAddressNotResolved

Route's next hop IP address cannot be resolved to a GCP resource.

RouteNextHopResourceNotFound

Route's next hop resource is not found.

RouteNextHopVpnTunnelNotEstablished

Route's next hop VPN tunnel is down (does not have valid IKE SAs).

RouteWrongNetwork

Packet is sent to a wrong (unintended) network. Example: you trace a packet from VM1:Network1 to VM2:Network2, however, the route configured in Network1 sends the packet destined for VM2's IP address to Network3.

RoutingLoop

Packet is stuck in a routing loop.

TrafficTypeBlocked

The type of traffic is blocked and the user cannot configure a firewall rule to enable it. See Always blocked traffic for more details.

UnknownExternalAddress

Destination external address cannot be resolved to a known target. If the address is used in a Google Cloud project, provide the project ID as test input.

UnknownInternalAddress

Destination internal address cannot be resolved to a known target. If this is a shared VPC scenario, verify if the service project ID is provided as test input. Otherwise, verify if the IP address is being used in the project.

Unspecified

Cause is unspecified.

VpcConnectorNotRunning

Packet could be dropped because the VPC connector is not in a running state.

VpcConnectorNotSet

Packet could be dropped because no VPC connector is set.

VpnTunnelLocalSelectorMismatch

The packet does not match a policy-based VPN tunnel local selector.

VpnTunnelRemoteSelectorMismatch

The packet does not match a policy-based VPN tunnel remote selector.
