You can edit the DHCP settings of an isolated organization VDC network. The DHCP service of an organization VDC network provides IP addresses from its address pool to VM NICs that are configured to request an address from DHCP. The service provides the address when the virtual machine powers on.
- These operations require the predefined organization administrator or system administrator roles or a role that includes an equivalent set of rights.
- Verify that your network is an isolated organization virtual data center network.
- On the Virtual Datacenters dashboard screen, click the card of the virtual data center you want to explore, and select Networks from the left panel.
- Click the name of the network that you want to edit.
- Click the IP Management tab.
- Select DHCP.
The DHCP settings display on the right.
- To enable DHCP, click Edit on the right of DHCP Pools Service.
- Toggle on the DHCP Pools Service and click Save.
Addresses requested by DHCP clients are pulled from a DHCP pool.
- Create a DHCP pool for the network.
- Click Add.
- Enter an IP address range for the pool.
The IP address range that you specify cannot overlap with the static IP address pool for the organization virtual data center.
- Specify the default lease time for the DHCP addresses in seconds.
The default value is 3,600 seconds.
- Specify the maximum lease time for the DHCP addresses in seconds.
This is the maximum length of time that the DHCP-assigned IP addresses are leased to the virtual machines. The default value is 7,200 seconds.
- Click Save.
