Parameter
Description
Lease Time
It specifies the validity period of an IP address assigned
by the DHCP server to a client.
When
the lease time expires:
−
If the client is still connected to the AP, the client automatically extends the lease time
and continues to use this IP address.
−
If the client has been shut down, the Ethernet cable between the
client and the AP has
been removed, or the wireless connection between the client and the AP is released,
the AP recycles the IP address. The
AP can then assign this IP address to any client
requesting an IP address.
It is recommended that you retain the
default value 1 day.
Subnet Mask
It specifies the subnet mask assigned by the DHCP server to clients. The default value is
255.255.255.0
.
Gateway
It specifies the gateway IP address assigned by the DHCP server to clients. The default value
is
192.168.0.254.
4UZK
When a client accesses a server or host located outside the network segment where the client
resides, the data from and to the client must be forwarded by a gateway. Generally, the IP
address of the gateway is the LAN IP address of the router in your
LAN.
Primary DNS
Server
It specifies the primary DNS server IP address assigned by the DHCP server to clients. The
default value is
192.168.0.254.
4UZK
To enable clients to access the internet, set this parameter to a correct DNS server IP address
or DNS prox
y IP address.
Secondary DNS
Server (optional)
It specifies the secondary DNS server IP address assigned by the DHCP server to clients.
This parameter is optional.
4UZK
If another DHCP server is available on your LAN, ensure that the IP address pool of the AP does not overlap the IP
address pool of that DHCP server. Otherwise, IP address conflicts may occur.
 Viewing the DHCP Client List
If the AP functions as a DHCP server, you can view the DHCP client list to understand the details
about the clients that obtain IP addresses from the DHCP server. The details include host names, IP
addresses, MAC addresses, and lease times.
To access the page, choose Network > DHCP Server and click DHCP Client List tab.
