Using the CLI to Configure DHCP Scopes
Follow these steps to configure DHCP scopes using the CLI.
Step 1 To create a new DHCP scope, enter this command:
config dhcp create-scope scope
Note If you ever want to delete a DHCP scope, enter this command: config dhcp delete-scope scope.
Step 2 To specify the starting and ending IP address in the range assigned to the clients, enter this command:
config dhcp address-pool scope start end
Note This pool must be unique for each DHCP scope and must not include the static IP addresses of
routers or other servers.
Step 3 To specify the network served by this DHCP scope (the IP address used by the management interface
with Netmask applied) and the subnet mask assigned to all wireless clients, enter this command:
config dhcp network scope network netmask
Step 4 To specify the amount of time (from 0 to 65536 seconds) that an IP address is granted to a client, enter
this command:
config dhcp lease scope lease_duration
Step 5 To specify the IP address of the optional router(s) connecting the controllers, enter this command:
config dhcp default-router scope router_1 [router_2] [router_3]
Each router must include a DHCP forwarding agent, which allows a single controller to serve the clients
of multiple controllers.
Step 6 To specify the optional domain name system (DNS) domain name of this DHCP scope for use with one
or more DNS servers, enter this command:
config dhcp domain scope domain
