DHCP Server

DHCP automatically allocates network addresses and also delivers configuration parameters dynamically to the clients from the DHCP Server. When DHCP server is enabled, it allows allocation of IP addresses to clients connected to the device. Navigate to CONFIGURATION > DHCP > DHCP Server. The DHCP Server screen appears.

Parameter Description

Status Specifies the status of Packet Forwarding on the AP device.

By default, it is disabled. To enable, select Enable from the drop down menu. Gateway MAC

Address

Specifies the MAC address of the destined gateway device. To configure, enter the

Gateway MAC Address in the box.

Uplink Port Name Specifies the port of the gateway, that should participate in Packet Forwarding. The

Uplink Port Name can be configured in three ways:

– Auto:Configure the Uplink Port Name to Auto,when the interface of the destined gateway port is unknown.Based on the configured peer MAC address, the AP device automatically detects the gateway port by checking within its bridge table.

– Ethernet: Configure the Uplink Port Name to Ethernet, when the destined gateway port is connected on ethernet interface of the AP device.

– WDS:Configure the Uplink Port Name to WDS, when the destined gateway port is connected on WDS interface of the AP device.

Based on the radio (interface 1 and interface 2) and the VAP enabled, the UpLink Port Name configured in WDS is represented as:

For example, if UpLink Port Name is WDS_1_2 then, 1 represents radio 1 (interface 1) and 2

represents VAP 2.

WDS_X_Y; where

X = the radio on which the VAP is enabled (interface 1 or interface 2)

Figure 5-47 DHCP Server

Tabulated below are the ‘DHCP Server’ parameters and the method to configure the configurable parameters:

Parameter Description

DHCP Server Status Specifies the status of the DHCP Server functionality on the device.

By default, it is disabled. To configure, select Enable or Disable from the drop down menu.

: If DHCP Server Status is enabled, it is recommended to set the IP address manually (Static IP Address). See Assigning the IP Address Manually

Max Lease Time Specifies the Maximum Lease time for which the DHCP client can have the IP address provided by the DHCP Server.

By default, the Max Lease Time taken is 86400 seconds. To configure, enter a value ranging from 3600-172800 seconds.

Max Lease Time

: If the Maximum Lease time is greater than Default Lease time, then the DHCP server offers the interface based configured Default Lease time. Whereas, if the Maximum Lease time is less than the Default lease time, then the lease time offered by the DHCP server will be Maximum Lease time.

DHCP Interface Settings

The DHCP Interface Settings Table contains the following information:

Subnet Mask Specifies the subnet mask to be sent to the client along with the assigned IP address. The netmask configured here should be greater than or equal to the netmask configured on the interface. To configure, enter the Net Mask.

Click OK and COMMIT, to save the configured parameters.

5.9.1.1 Add an Entry to DHCP Pool Table

To add an entry to the DHCP Pool Table, click Add in the DHCP Server screen. The DHCP Pool Table Add Row screen appears.

Figure 5-48 DHCP Pool - Add an Entry

Default Gateway Specifies the default gateway to be sent to the client along with the assigned IP Address. Default Gateway is a node that serves as an accessing point to another network. To configure, enter the Default Gateway address.

Primary DNS Specifies the primary DNS (Domain Name Server) IP address to be sent to the client. To configure, enter the Primary DNS address.

Secondary DNS Specifies the secondary DNS IP address to be sent to the client. To configure, enter the Secondary DNS address.

Default Lease Period Specifies the least time offered by the DHCP server, to the client on that interface.

By default, it is taken as 86400 seconds. To configure, enter a value ranging from 3600 to 172800 seconds.

Status Specifies the status of DHCP server functionality over the interface.

By default, it is disabled. To configure, select Enable or Disable from the drop down menu.

DHCP Pool Table

The DHCP Pool Table contains the following information: Start IP Address Specifies the Start IP Address of the pool.

End IP Address Specifies the End IP Address of the pool.

Delete This parameter allows you to delete the added pool entry.

:

• A pool entry can be deleted but not edited.

Configure the following parameters:

Click Add, to save the added entry.

: You can add a maximum of five pool entries per interface.

Parameter Description

Pool Interface Specifies the interface type (ethernet or wireless). The device supports only Bridge mode. Start IP Address See DHCP Pool Table

End IP address See DHCP Pool Table

Entry Status Specifies the status of the pool entry being added.
