Create a Distributed Port Group

Procedure

1. In the navigation pane, choose Inventory > Network Resource.
2. In the resource tree, right-click the target distributed switch and select New Distributed Port Group.
3. In the New Distributed Port Group dialog, complete basic configuration.

   Option	Description
   Name	Enter a name for the distributed port group.
   Description	Enter a brief description for the distributed port group.
   Distributed Switch	Select the distributed switch for the distributed port group.
   VLAN Type	Select a VLAN type. If you select standard VLAN, enter the VLAN ID.
   DHCP Service	Select whether to enable the service that automatically assigns IP addresses to internal platform resources.
   DHCP Service IP	Set the IP address used by the DHCP service.
   DNS	Set the DNS resolution service for the distributed port group.

4. Enable IP address management and configure network ranges as needed.

   After IP address management is enabled, you can add network ranges to the distributed port group. IP addresses in the network ranges can be assigned through DHCP to resources that use this network.

   IPv4 Address Type

   Option	Description
   IP Allocation Policy	After the DHCP service is enabled, the following allocation policies are supported: Random allocation: The system randomly assigns IP addresses in the added network range. Allocate in Order: The system assigns all available IP addresses in the added network range in ascending order. Released IP addresses are assigned in the next allocation. Example: Assume that the network range is 192.168.0.101～192.168.0.120, within which 192.168.0.101～192.168.0.108 are allocated. If 192.168.0.106 is released, it will be assigned first in the next allocation. Allocate in Cycle: The system assigns IP addresses in the added network range in ascending order. Addresses released during allocation are assigned after all currently available IP addresses have been assigned once. Example: Assume that the network range is 192.168.0.101～192.168.0.120, within which 192.168.0.101～192.168.0.108 are allocated. If 192.168.0.106 is released, it will be assigned after 192.168.0.120 is used.
   Network Range Method	The following network range methods are supported: IP Range: Enter the start IP address, end IP address, subnet mask, and gateway of the network range. Note: Do not include the gateway, broadcast address, or network address in the added IP range. CIDR: Enter the CIDR block and gateway. The gateway can be the first or last address in the CIDR block. If the gateway is left empty, the first address in the CIDR block is used by default.

   IPv6 Address Type

   Option	Description
   Network Range Method	The following network range methods are supported: IP Range: Enter the start IP address, end IP address, prefix length, and gateway of the network range. CIDR: Enter the CIDR block.
   IP Allocation Mode	Select the IPv6 address allocation mode: Stateful-DHCP: Stateful DHCP configuration. The interface address and other parameters are all configured through DHCP. The IP range method supports only this allocation mode. Stateless-DHCP: Stateless DHCP configuration. The interface address is derived from the prefix in router advertisements and the interface MAC address, and other parameters are configured through DHCP. SLAAC: Stateless address autoconfiguration. The interface address is derived from the prefix in router advertisements, and other parameters are also included in router advertisements.

5. After confirming that the configuration is correct, click OK.
