Updating a VPC Channel

Function

This API is used to update the parameters of a VPC channel.

If the VPC channel is overwritten with an empty backend instance list, all the existing backend instances will be deleted.

If the VPC channel is overwritten with an empty backend server group list, all the existing backend server groups will be deleted.

Calling Method

For details, see Calling APIs.
