Default Value:

Query Parameters

limit: integer

Minimum Value: 1

Maximum Value: 1000

For list pagination. The maximum number of results per page, or items to return in a paginated List call. 1 is the minimum, 1000 is the maximum.

Default Value: 100
page: string

Minimum Length: 1

Maximum Length: 512

For list pagination. The value of the opc-next-page response header from the previous List call.

Default Value: 0
sortBy: string

The optional field to sort the results by.

Allowed Values: [ "TIMECREATED", "NAME" ]
sortOrder: string

The sort order to use, either ascending (ASC) or descending (DESC).

Default Value: ASC

Header Parameters

if-none-match: string

Minimum Length: 0

Maximum Length: 1

Pattern: ^[*]$

The system returns the requested resource, with a 200 status, only if the resource has no etag matching the one specified. If the condition fails for the GET and HEAD methods, then the system returns the HTTP status code 304 (Not Modified). Example: example-etag
opc-request-id: string

Unique Oracle-assigned identifier for the request. Provide this request OCID if you need to contact Oracle about this request.

Response

Supported Media Types

application/json

200 Response

Retrieving the list of backends associated with backend sets of a network load balancer.

Headers

opc-next-page: string

For pagination of a list of items. When paging through a list, if this header appears in the response, then a partial list might have been returned. Include this value as the `page` parameter for the subsequent GET request to get the next batch of items.
opc-request-id: string

Unique Oracle-assigned identifier for the request. If you must contact Oracle about a particular request, then provide the request identifier.

Type: object

Show Source

ipAddress: string

The IP address of the backend server. Example: 10.0.0.3
ipVersion: string

Default Value: IPV4

Allowed Values: [ "IPV4", "IPV6" ]

IP version associated with the BackendSummary object.
isBackup: boolean

Default Value: false

Whether the network load balancer should treat this server as a backup unit. If true, then the network load balancer forwards no ingress traffic to this backend server unless all other backend servers not marked as "isBackup" fail the health check policy. Example: false
isDrain: boolean

Default Value: false

Whether the network load balancer should drain this server. Servers marked "isDrain" receive no incoming traffic. Example: false
isOffline: boolean

Default Value: false

Whether the network load balancer should treat this server as offline. Offline servers receive no incoming traffic. Example: false
name: string

A read-only field showing the IP address/IP OCID and port that uniquely identify this backend server in the backend set. Example: 10.0.0.3:8080, or ocid1.privateip..unique_ID:443 or 10.0.0.3:0
port(required): integer(int32)

The communication port for the backend server. Example: 8080
targetId: string

The IP OCID/Instance OCID associated with the backend server. Example: ocid1.privateip..unique_ID
weight: integer(int32)

The network load balancing policy weight assigned to the server. Backend servers with a higher weight receive a larger proportion of incoming traffic. For example, a server weighted '3' receives three times the number of new connections as a server weighted '1'. For more information about load balancing policies, see [How Network Load Balancing Policies Work](/Content/Balance/Reference/lbpolicies.htm). Example: 3
