Description

This command configures a DHCP pool on the VirtualController. 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 anInstant APreceives 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, theInstant APanswers the request.

Parameter	Description
dhcp-relay	Enables the AP to operate as a DHCP relay agent and forward DHCP information to a server.
dhcp-server	Configures the server to which the AP relays the DHCP information for profiling.
dns-cache	Enables DNS caching on theInstant AP, which allows theInstant APto respond to DNS requests from cache or deny the request immediately if the upstream DNS server is not reachable. When DNS caching is enabled, the DNS server configuration details are ignored.
dns-server	定义了DNS服务器的IP地址。You can specify up to eight IP addresses as a comma separated list.
domain-name	Defines the name of domain to which the client belongs.
lease-time	Configures the duration of the DHCP lease in minutes. Range:2–43200 minutes Default:720 minutes
subnet	Defines IP address of the subnet.
subnet-mask	Defines the subnet mask of the IP address,
no…	Removes any existing configuration

Example

The following command configures a DHCP pool:

(Instant AP)(config)# ip dhcp pool

(Instant AP)(DHCP)# domain-name example.com

(Instant AP)(DHCP)# dns-cache

(Instant AP)(DHCP)# dns-server 192.0.2.1

(Instant AP)(DHCP)# lease-time 20

(Instant AP)(DHCP)# subnet 192.0.2.0

(Instant AP)(DHCP)# subnet-mask 255.255.255.0

(Instant AP)(DHCP)# end

(Instant AP)# commit apply
