   3. Click OK.
   4. Click Next.
4. Configure a DHCP address pool.
   1. On the 3.Configure DHCP page, click Create under DHCP Address Pool.
   2. Configure the parameters in the displayed window. For description of the parameters, see Table 3 and Table 4.

      Table 3 Parameters for configuring a DHCP global address pool

      Parameter	Description
      DHCP status	Whether to enable the DHCP function globally.
      Address pool type	DHCP address pool type (global address pool/interface address pool)
      Address pool name	Name of the global address pool. The name is a string of 1 to 64 characters, including only numbers, letters, dots (.), hyphens (-), and underscores (_). A single hyphen (-) or multiple hyphens (--) alone cannot be used as an address pool name.
      Subnet address	Available network segment addresses in a global address pool.
      Subnet mask	Subnet mask of the IP address assigned to the DHCP client; namely, the subnet mask of the current interface. The gateway IP address and subnet mask together identify the range of an interface address pool.
      Vendor-defined	User-defined option for the global IP pool. The options are as follows: None: indicates that no user-defined option is configured for an address pool. ascii: indicates that the user-defined option is an ASCII character string. cipher: indicates that the user-defined option is a password string. hex: indicates that the user-defined option is a hexadecimal number. ip-address: indicates that the user-defined option is an IP address. One to eight IP addresses can be specified. sub-option: indicates that a sub-option is configured for the user-defined option. If sub-option is selected, you also need to set the sub-option parameter.
      Gateway IP	Egress gateway IP address in a global address pool. To add a gateway IP address, enter a gateway IP address and click . You can repeat this operation to add a maximum of eight gateway IP addresses. To delete a gateway IP address, select a gateway IP address and click .
      Address pool interface	Interface that can use addresses in the address pool. Users going online through this interface can obtain configuration information, such as IP addresses, from the global address pool. To add an interface, select an interface and click . To add multiple interfaces, repeat this operation. To delete an interface, select an interface and click .
      Not allocated IP	IP address that will not be dynamically allocated to clients. When IP addresses are assigned to other servers such as DNS servers, the IP addresses cannot be assigned to DHCP clients. Specify these IP addresses as forbidden IP addresses. This operation avoids IP address conflicts and shortens the IP address detection time during IP address assignment, which improves DHCP efficiency. Perform the following operations to add or delete forbidden IP addresses: Adding forbidden IP addresses: Set the start and end IP addresses and click . To add multiple forbidden IP addresses or IP address segments, repeat this operation. Deleting forbidden IP addresses: Select the check boxes of forbidden IP addresses or select the check box next to Forbidden IP, and click .

      Table 4 Parameters for configuring a DHCP interface address pool

      Parameter	Description
      DHCP status	Whether to enable the DHCP function globally.
      Address pool type	DHCP address pool type (global address pool/interface address pool)
      Select Interface	Interface of the DHCP server on which the address pool is configured. The IP addresses in the network segment to which the interface IP address belongs can be allocated.
      Interface IP address	IP address of the current interface; namely, the gateway address of the DHCP client.
      Mask	Subnet mask of the IP address assigned to the DHCP client; namely, the subnet mask of the current interface. The gateway IP address and subnet mask together identify the range of an interface address pool.
      Vendor-defined	User-defined option for the global IP pool. The options are as follows: None: indicates that no user-defined option is configured for an address pool. ascii: indicates that the user-defined option is an ASCII character string. cipher: indicates that the user-defined option is a password string. hex: indicates that the user-defined option is a hexadecimal number. ip-address: indicates that the user-defined option is an IP address. One to eight IP addresses can be specified. sub-option: indicates that a sub-option is configured for the user-defined option. If sub-option is selected, you also need to set the sub-option parameter. NOTE: If the value of sub-option is 1, the sub-option type is fixed at hex. If the value of sub-option is 2, the sub-option type is fixed at ip-address. If the value of sub-option is 3, the sub-option type is fixed at ascii, and only an IP address such as 10.1.1.1 can be configured in the text box.
      Not allocated IP	IP address that will not be dynamically allocated to clients. When IP addresses are assigned to other servers such as DNS servers, the IP addresses cannot be assigned to DHCP clients. Specify these IP addresses as forbidden IP addresses. This operation avoids IP address conflicts and shortens the IP address detection time during IP address assignment, which improves DHCP efficiency. Perform the following operations to add or delete forbidden IP addresses: Adding forbidden IP addresses: Set the start and end IP addresses and click . To add multiple forbidden IP addresses or IP address segments, repeat this operation. Deleting forbidden IP addresses: Select the check boxes of forbidden IP addresses or select the check box next to Forbidden IP, and click .

      

      Gateway IP and Not allocated IP must be in the address pool. To ensure correct configuration, the Subnet address and Subnet mask parameters of the global address pool and the Select Interface parameter of the interface address pool can be modified or selected only when Gateway IP and Not allocated IP are not configured.
