Windows provided with DHCP
If the CVM is provided with DHCP, you can view its secondary ENI and IP by following steps below without any further configuration:
1. Log in to the CVM, and select Control Panel -> Network and Internet -> Network and Sharing Center to check the secondary ENI that has been automatically obtained.
2. Click the “Ethernet 2” secondary ENI to view its information.
3. In the Ethernet 2 Status pop-up window, click Properties.
4. In the Ethernet 2 Properties pop-up window, double-click Internet Protocol Version 4 (TCP/IPv4).
5. In the Internet Protocol Version 4 (TCP/IPv4) pop-up window, you can see Obtain an IP address automatically is selected, so there is no need to enter one.
6. Return to the Ethernet 2 Status pop-up window and click Details. As shown in the figure below, DHCP is enabled and the IP automatically obtained is displayed.
DHCP not set
If the CVM is not provided with DHCP, you need to configure the private IP by following the steps below:
2. Log in to the CVM and select Control Panel -> Network and Internet -> Network and Sharing Center.
3. Click to edit the “Ethernet 2” secondary ENI.
4. In the Ethernet 2 Status pop-up window, click Properties.
