Table 3 Request body parameters

Parameter

Mandatory

Type

Description

central_network_connection

Yes

UpdateCentralNetworkConnection object

Details of the central network connection to be updated.- bandwidth_type: bandwidth package (billed by fixed bandwidth or traffic) or test bandwidth (free bandwidth for testing cross-region connectivity).- global_connection_bandwidth_id: mandatory if bandwidth_type is BandwidthPackage.- bandwidth_size: mandatory if bandwidth_type is BandwidthPackage (the total of cross-site connection bandwidths cannot exceed the bandwidth specified by the bandwidth package) or Traffic and is not available if bandwidth_type is set to TestBandwidth.
