Response body

Represents a traffic classification rule that describes one or more match conditions along with the action to be taken when traffic matches this condition.

If successful, the response body contains data with the following structure:

Fields
kind

string

[Output only] Type of the resource. Always compute#networkPolicyTrafficClassificationRule for network policy traffic classification rules
ruleName

string

An optional name for the rule. This field is not a unique identifier and can be updated.
description

string

An optional description for this resource.
priority

integer

An integer indicating the priority of a rule in the list. The priority must be a positive value between 1 and 2147482647. The priority values from 2147482648 to 2147483647 (1000) are reserved for system default network policy rules. Rules are evaluated from highest to lowest priority where 1 is the highest priority and 2147483647 is the lowest priority.
match

object

A match condition that outgoing traffic is evaluated against. If it evaluates to true, the corresponding 'action' is enforced.
match.srcIpRanges[]

string

CIDR IP address range. Maximum number of source CIDR IP ranges allowed is 5000.
match.destIpRanges[]

string

CIDR IP address range. Maximum number of destination CIDR IP ranges allowed is 5000.
match.layer4Configs[]

object

Pairs of IP protocols and ports that the rule should match.
match.layer4Configs[].ipProtocol

string

The IP protocol to which this rule applies. The protocol type is required when creating a traffic classification rule. This value can either be one of the following well known protocol strings (tcp, udp, icmp, esp, ah, ipip, sctp), or the IP protocol number.
match.layer4Configs[].ports[]

string

An optional list of ports to which this rule applies. This field is only applicable for UDP or TCP protocol. Each entry must be either an integer or a range. If not specified, this rule applies to connections through any port.

Example inputs include: ["22"], ["80","443"], and ["12345-12349"].
action

object

The Action to perform when the client connection triggers the rule.
action.type

string

Always "apply_traffic_classification" for traffic classification rules.
action.trafficClass

enum

The traffic class that should be applied to the matching packet.
action.dscpMode

enum

The traffic class that should be applied to the matching packet.
action.dscpValue

integer

Custom DSCP value from 0-63 range.
ruleTupleCount

integer

[Output Only] Calculation of the complexity of a single network policy rule.
targetServiceAccounts[]

string

A list of service accounts indicating the sets of instances that are applied with this rule.
targetSecureTags[]

object

A list of secure tags that controls which instances the traffic classification rule applies to. If targetSecureTag are specified, then the traffic classification rule applies only to instances in the VPC network that have one of those EFFECTIVE secure tags, if all the targetSecureTag are in INEFFECTIVE state, then this rule will be ignored. targetSecureTag may not be set at the same time as targetServiceAccounts. If neither targetServiceAccounts nor targetSecureTag are specified, the traffic classification rule applies to all instances on the specified network. Maximum number of target label tags allowed is 256.
targetSecureTags[].name

string

Name of the secure tag, created with TagManager's TagValue API.
targetSecureTags[].state

enum

[Output Only] State of the secure tag, either EFFECTIVE or INEFFECTIVE. A secure tag is INEFFECTIVE when it is deleted or its network is deleted.
disabled

boolean

Denotes whether the network policy rule is disabled. When set to true, the network policy rule is not enforced and traffic behaves as if it did not exist. If this is unspecified, the network policy rule will be enabled.
