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 largest address pool supported is 2048. The default size of the IP address pool is 512.
When the DHCP server is configured and if the IAP automatically determines a suitable DHCP pool for networks.
You can configure a domain name, DNS server and DHCP server for client IP assignment using Instant UI or CLI.
|1.||Click the Instant main window. The window appears.link at top right corner of the|
|2.||In the DHCP tab, enter the domain name of the client in the Domain name text box.|
|3.||Enter the IP addresses of the DNS servers separated by comma(,) in the DNS server text box.|
|4.||Enter the duration of the DHCP lease in the Lease time text box.|
|5.||Select Minutes, Hours, or Days for the lease time from the drop-down list next to Lease time. The default lease time is 0.|
|6.||Enter the network in thetext box.|
|7.||Enter the mask in thetext box.|
To provide simultaneous access to more than 512 clients, use the Network and Mask fields to specify a larger range. While the network (or prefix) is the common part of the address range, the mask (suffix) specifies how long the variable part of the address range is.
|8.||Click OK to apply the changes.|
To configure a DHCP pool:
(Instant Access Point)(config)# ip dhcp pool
(Instant Access Point)(DHCP)# domain-name <domain>
(Instant Access Point)(DHCP)# dns-server <DNS-IP-address>
(Instant Access Point)(DHCP)# lease-time <lease-time>
(Instant Access Point)(DHCP)# subnet <IP-address>
(Instant Access Point)(DHCP)# subnet-mask <subnet-mask>
To view the DHCP database:
(Instant Access Point)# show ip dhcp database
