Parameter Description
Default router If Distributed, L2 is selected for the type of DHCP scope, specify the IP address of
the default router.
DNS server If required, specify the IP address of a DNS server.
Domain name If required, specify the domain name.
Lease time Specify a lease time for the client in minutes within a range of 2–1440 minutes. The
default value is 720 minutes.
Dynamic DNS Select the Dynamic DNScheck box to enable dynamic DNS on the Distributed, L3
client.
Key—Enter the TSIG shared secret key.
IP Address Range Specify a range of IP addresses to use. To add another range, click the + icon. You
can specify up to four different ranges of IPaddresses.
l For the Distributed, L2 mode, ensure that all IP ranges are in the same subnet
as the default router. On specifying the IP address ranges, a subnet validation is
performed to ensure that the specified ranges of IP address are in the same
subnet as the default router and subnet mask. The configured IP range is
divided into blocks based on the configured client count.
l For the Distributed, L3 mode, you can configure any discontiguous IP ranges.
The configured IP range is divided into multiple IP subnets that are sufficient to
accommodate the configured client count.
NOTE: You can allocate multiple branch IDs (BID) per subnet. The W-IAP generates
a subnet name from the DHCP IP configuration, which the controller can use as a
subnet identifier. If static subnets are configured in each branch, all of them are
assigned the with BID 0, which is mapped directly to the configured static subnet.
Option
Specify the type and a value for the DHCP option. You can configure the
organization-specific DHCP options supported by the DHCP server. For example,
176, 242, 161, and so on. To add multiple DHCP options, click the + icon. You can
add up to eight DHCP options.

4. Click Next.
5. Specify the number of clients to use per branch. The client count configured for a branch determines the
use of IP addresses from the IP address range defined for a DHCP scope. For example, if 20 IP addresses
are available in an IP address range configured for a DHCP scope and a client count of 9 is configured, only a
few IP addresses (in this example, 9) from this range will be used and allocated to a branch. The W-IAP does
not allow the administrators to assign the remaining IP addresses to another branch, although a lower value
is configured for the client count.
6. Click Next. The Static IP tab is displayed.
7. Specify the number of first and last IP addresses to reserve in the subnet.
8. Click Finish.
