DeleteVSwitchCidrReservation - Virtual Private Cloud - Alibaba Cloud Documentation Center

Deletes a reserved CIDR block of a vSwitch.

Operation description

Description

Before you call this operation, make sure that the IP address allocated to an elastic network interface (ENI) from the reserved CIDR block is deleted. If the IP address of the ENI is not deleted, call UnassignPrivateIpAddresses or UnassignIpv6Addresses to delete the IPv4 or IPv6 address.
DeleteVSwitchCidrReservation is an asynchronous operation. After a request is sent, the system returns a request ID and runs the task in the background. You can call ListVSwitchCidrReservations to query the status of the task:
- If the reserved CIDR block is in the Releasing state, it is being released.
- If the reserved CIDR block is in the Released state, it is released.

Debugging

You can run this interface directly in OpenAPI Explorer, saving you the trouble of calculating signatures. After running successfully, OpenAPI Explorer can automatically generate SDK code samples.
