Example: Configuring DHCP server (WLAN
application)
Network configuration
As shown in
, the DHCP server (Device) assigns an IP address, the AC address, a gateway
address, and a DNS server address to the AP. Configure the DHCP server as follows:
•
Create an address pool, specify the subnet 10.1.1.0/24, and configure the address lease
duration as ten days.
•
Specify the gateway address and the DNS server address as 10.1.1.1 and 20.1.1.1.
•
Configure Option 43. Specify the AC address as 10.1.1.3. The formats of Option 43 and the
PXE server address sub-option are shown in
. The value of Option 43
configured on the DHCP server in this example is 80 07 00 00 01 0A 01 01 03.
{
The number 80 is the value of the sub-option type.
{
The number 07 is the value of the sub-option length.
{
The numbers 00 00 are the value of the PXE server type.
{
The number 01 indicates the number of servers.
{
The numbers 0A 01 01 03 indicate that the IP address of the AC is 10.1.1.3.
•
To avoid address conflicts, exclude the IP addresses 10.1.1.1 and 10.1.1.3 of the gateway and
the AC from dynamic allocation.
