DescribeRules

The action to perform. Valid value: DescribeRules.

The frontend listener port used by the SLB instance. Valid values: 1–65535

The ID of the SLB instance

The ID of the region to which the SLB instance belongs.

You can call the DescribeRegions API to query this parameter.

Request ID

A list of the forwarding rules

The ID of a forwarding rule

The name of the forwarding rule. The name must be 1 to 80 characters in length and can contain letters, numbers, hyphens (-), forward slashes (/), periods (.), and underscores (_).

The request domain name attached to a forwarding rule

The request path attached to a forwarding rule

The ID of the destination VServer group bound to a forwarding rule

The Cookie configured on the server

It can contain 1 to 200 characters, including only ASCII letters and numbers. It cannot contain commas (,), semicolons (;), or spaces or start with a dollar sign ($).

Cookie expiration period Valid values: 1 to 86400 (seconds)

Whether to enable health checks

Valid values: on | off

The port of the backend server used for health checks.

Valid values: 1–65535

The domain name used for health checks. Valid values:

• domain: domain name, which must be 1 to 80 characters in length and can contain letters, numbers, periods (.), and hyphens (-).

The HTTP status code indicating that the health check is normal. Separate multiple status codes by commas. Default value: http_2xx.

Valid values: http_2xx | http_3xx | http_4xx | http_5xx

Time interval between two health checks

Valid values: 1–50 (seconds)

The amount of time to wait for the response from a health check. If the backend ECS instance does not send a correct response in the specified time, the health check fails.

Valid values: 1–300 (seconds)

The URI used for health checks.

The number of consecutive successes of health checks before a backend server is declared as healthy (from failure to success).

Valid values: 2–10

Whether a forwarding rule inherits the settings of a health check, session persistence, and scheduling algorithm from a listener

Valid values: on | off

• off: The rule customs health check and session persistence settings instead of inheriting them.
• on: The rule inherits the settings from the listener.

Scheduling algorithm. Valid values:

• wrr (default value): A backend server with a higher weight is more likely to be polled.
• wlc: A backend server with a higher weight will receive more requests. When the weight is the same, the server with a smaller number of connections is more likely to be polled.
• rr: Requests are evenly and sequentially distributed to the backend servers.

Whether to enable session persistence

Valid values: on | off

The method used to handle the Cookie. Valid values:

• insert: Insert the Cookie. When a client accesses SLB for the first time, SLB inserts Cookies into response requests (that is, SLB inserts SERVERID into the HTTP/HTTPS response data packets). The next time the client accesses SLB with the Cookies, SLB will direct and forward the requests to the previously recorded backend server.
• server: Rewrite the Cookie. SLB will overwrite the original cookie whena new cookie is set. The next time the client carries the new cookie to access the SLB instance, the listener will distribute the request to the previously recorded backend server.

The number of consecutive failures of health checks before a backend server is declared as unhealthy (from success to failure).

Valid values: 2–10
