Usage Guidelines
Use this command to configure a DHCP pool. The DHCP server is a built-in server, used for
networks in which clients are assigned IP address by the Virtual Controller. You can
customize the DHCP pool subnet and address range to provide simultaneous access to
more number of clients. The pool can support up to 2048 addresses. The default size of the
IP address pool is 512. When an AP receives a DHCP request from a client, it examines the
origin of the request to determine if it a response must be sent. If the IP address of the VLAN
matches a configured DHCP pool, the AP answers the request.
Example
The following command configures a DHCP pool:
(scalance)(config)# ip dhcp pool
(scalance)(DHCP)# domain-name example.com
(scalance)(DHCP)# dns-cache
(scalance)(DHCP)# dns-server 192.0.2.1
(scalance)(DHCP)# lease-time 20
(scalance)(DHCP)# subnet 192.0.2.0
(scalance)(DHCP)# subnet-mask 255.255.255.0
(scalance)(DHCP)# end
