Table 3 Request body parameters

Parameter

Mandatory

Type

Description

bandwidth_policy

Yes

Array of BandwidthPolicyDto objects

The traffic limiting rules. Each element in the array corresponds to the maximum bandwidth in a time period. A maximum of five periods are allowed, and the periods cannot overlap.

Array length: 0 to 5

Parameter

Mandatory

Type

Description

end

Yes

String

The end time of the traffic limiting rule. The format is hh:mm, for example, 12:03.
