ListTrafficMarkingPolicies - Cloud Enterprise Network - Alibaba Cloud Documentation Center

Queries the details about a traffic marking policy, such as the status and priority.

Operation description

Before you call the ListTrafficMarkingPolicies operation, take note of the following limits:

Specify at least one of the TransitRouterId and TrafficMarkingPolicyId parameters.
If you do not specify a traffic marking policy ID (TrafficMarkingPolicyId), the operation queries only the information about the traffic marking policy based on the TransitRouterId, TrafficMarkingPolicyName, and TrafficMarkingPolicyDescription parameters. The TrafficMatchRules parameter that contains the information about the traffic classification rules is not returned.
If you specify a traffic marking policy ID (TrafficMarkingPolicyId), the operation queries the information about the traffic marking policy and traffic classification rules. The TrafficMatchRules parameter is returned in the response. If the value of the TrafficMatchRules parameter is an empty array, the traffic marking policy does not contain a traffic classification rule.

TrafficMarkingPolicyName	string	The name of the traffic marking policy.	nametest
Priority	integer	The priority of the traffic marking policy. A lower value indicates a higher priority.	5
TrafficMarkingPolicyDescription	string	The description of the traffic marking policy.	desctest
TrafficMatchRules	object []	The traffic classification rules.
MatchDscp	integer	The DSCP value used to match data packets. Note If the value of the MatchDscp parameter is -1, data packets are considered a match regardless of the DSCP value.	6
DstCidr	string	The destination CIDR block that is used to match packets.	192.168.120.0/24
