Figure 4-4 DHCP Server Configuration Screen

You can configure and view the following parameters within the DHCP Server Configuration screen:

NOTE: You must reboot the AP before changes to any of these DHCP server parameters take effect.

• Enable DHCP Server: Place a check mark in the box provided to enable DHCP Server functionality.

NOTE: You cannot enable the DHCP Server functionality unless there is at least one IP Pool Table Entry configured.

• Subnet Mask: This field is read-only and reports the Access Point’s current subnet mask. DHCP clients that receive

dynamic addresses from the AP will be assigned this same subnet mask.

• Gateway IP Address: The AP will assign the specified address to its DHCP clients.

• Primary DNS IP Address: The AP will assign the specified address to its DHCP clients.

• Secondary DNS IP Address: The AP will assign the specified address to its DHCP clients.

• Number of IP Pool Table Entries: This is a read-only field that reports the number of entries in the IP Pool Table.

• IP Pool Table Entry: This entry specifies a range of IP addresses that the AP can assign to its wireless clients. Click

Add to create a new entry. Click Edit to change an existing entry. Each entry contains the following fields:

– Start IP Address: The first IP address in the pool. IP addresses must be within the same subnet as the AP.

– End IP Address: The last IP address in the pool. IP addresses must be within the same subnet as the AP.

– Default Lease Time (optional): The default time value for clients to retain the assigned IP address. DHCP

automatically renews IP Addresses without client notification. This parameter supports a range between 3600 and

86400 seconds. The default is 86400 seconds. If this field is left blank, the default (86400) is used.

– Maximum Lease Time (optional): The maximum time value for clients to retain the assigned IP address. DHCP

automatically renews IP Addresses without client notification. This parameter supports a range between 3600 and

86400 seconds. The default is 86400 seconds. If this field is left blank, the default (86400) is used.

NOTE: The Default Lease Time cannot be larger than the Maximum Lease Time. If you set the Maximum Lease

Time, you should also set the Default Lease Time to ensure that the Default Lease Time is less than the

Maximum.
