In the IP Pool List area, click Create. In the Create IP Pool dialog box that is displayed, set parameters described in Table 12-1 and Table 12-2.
Click OK.
Table 12-1 Parameters for creating a global IP pool
Parameter | Description |
|---|---|
IP pool name | Name of a global IP pool. It is a string of 1 to 64 characters and can only contain digits, letters, dots (.), hyphens (-), and underlines (_). The value cannot be - or --. |
Subnet address | Network segment that can be allocated in the global IP pool. |
Subnet mask | Subnet mask of the IP address assigned to the DHCP client, that is, subnet mask of the selected interface. The gateway IP address and the subnet mask identify an IP pool of the interface. |
Gateway IP | Egress gateway address of the global IP pool. |
Interface used by IP pool | Interface used by the IP pool. Users who go online from this interface can obtain configuration information such as IP addresses from the global IP pool. |
Lease | IP address lease of DHCP clients, that is, duration during which IP addresses assigned to DHCP clients take effect. Set this parameter based on the duration during which DHCP clients of the interface IP pool are connected to the network. For example, set a short lease, such as 8 hours, for wireless clients who frequently connect to and disconnect from the wireless network. Set a long lease even a permanent lease for stable clients. |
Vendor-defined | User-defined option for the global IP pool. The options are as follows: NOTE: |
Primary DNS server | Primary DNS server address assigned to the DHCP client. |
Secondary DNS server | Secondary DNS server address assigned to the DHCP client. When the primary DNS server fails to perform domain name resolution, the DHCP client sends a domain name resolution request to the secondary DNS server. |
Primary WINS server | Primary WINS server address assigned to the DHCP client. The DHCP client running the Windows operating system uses the Network Basic Input Output System (NetBIOS) protocol for communication. The NetBIOS server translates host names to IP addresses for the client. The resolution of the NetBIOS name to an IP address is done locally, by broadcasts, or by a WINS Server. Ensure that the route between the primary WINS server and the DHCP server is reachable. |
Secondary WINS server | Secondary WINS server address assigned to the DHCP client. When the primary WINS server fails to perform NetBIOS name resolution, the DHCP client sends a NetBIOS name resolution request to the secondary WINS server. Ensure that the route between the secondary WINS server and the DHCP server is reachable. |
DNS domain name | Suffix of the domain name that the DNS server allocates to the DNS client. |
Forbidden 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: |
Static IP/MAC address | Binding between assignable IP addresses and MAC addresses of the clients. When receiving a request for applying for an IP address from a client matching the MAC address, the DHCP server assigns the fixed IP address bound to the client's MAC address to this client. Perform the following operations to create or delete a static IP address entry: |
NetBIOS type | Type of the NetBIOS node. The options are as follows: |
Table 12-2 Parameters for creating an interface IP pool
Parameter | Description |
|---|---|
Select interface | Interface mapping the interface IP pool of a DHCP server. The network segment that the interface IP address belongs to must be allocable. |
Interface IP | IP address of the selected interface, that is, the gateway address used by the DHCP client. |
Mask | Subnet mask of the IP address assigned to the DHCP client, that is, subnet mask of the selected interface. The gateway IP address and the subnet mask identify an IP pool of the interface. |
Lease | For details, see Table 12-1. |
Vendor-defined | User-defined option for the interface IP pool. The options are as follows: NOTE: |
Primary DNS server | For details, see Table 12-1. |

12.1.3 Relay
Context
By using a DHCP relay agent, DHCP clients on a LAN can communicate with DHCP servers on other network segments, and obtain IP addresses from them. The DHCP clients on different network segments can also use one DHCP server, which reduces costs and achieves centralized device management.
Before configuring the DHCP relay function, you must configure DHCP server groups.
DHCP relay is introduced to transmit packets between DHCP clients and a DHCP server that are in different network segments. A DHCP relay agent can transparently transmit DHCP broadcast packets between DHCP clients and a DHCP server that are in different network segments.
In applications, the DHCP relay function is generally implemented on a VLANIF interface of the device. This interface needs to be configured with an IP relay address to specify the DHCP server group. An IP relay address refers to the IP address of the DHCP server group specified on the DHCP relay agent. When DHCP relay is enabled on an interface, broadcast DHCP packets received on this interface are sent to the specified DHCP server group.
If no DHCP server group is configured on a network, the DHCP relay function can be enabled on the device, so that DHCP Request packets from clients can be transmitted to the DHCP server group on another network through the DHCP relay agent. To enable clients to obtain IP addresses, a DHCP server in the DHCP server group must use a global address pool. That is, the interface of the server connected to the DHCP relay agent cannot be configured with any address pool.

You can check the routing table to view routing information about the device, which helps you manage the networks.
A routing table contains the following key data for each IP packet.
Item | Description |
|---|---|
Destination IP Address | Indicates the destination IP address or network of IP packets. |
Subnet Mask | Indicates the subnet mask length of the destination address. The network mask is used with the destination address to identify the address of the network segment where the destination host or router resides. |
Route Type | Indicates the routing protocol. |

Outbound Interface | Indicates the outbound interface of the route, that is, local router interface from which packets are forwarded. |
Procedure
Choose IP Service > Route > Routing Table.

12.2.2 Static Route Configuration
Context
Generally, static routes are applicable to the networks with simple structures. Configuring static routes facilitates route management.
Procedure
