WM Access Domain Services Configuration
To modify time limits for IP assignments:
1 From the main menu, click WM-AD Configuration. The WM-AD Configuration screen is
displayed.
2 In the left pane WM Access Domains list, click the WM-AD you want to set time limits for. The
Topology tab is displayed.
3 In the Lease default box, type the default time limit. The default time limit dictates how long a
wireless device can keep the DHCP server assigned IP address. The default value is 36000 seconds
(10 hours).
4 In the Lease max box, type the maximum time limit. The default time limit is 2539000 seconds
(approximately 705 hours or 29 days).
Setting the Name Server Configuration
Although this procedure could also apply to any WM-AD type, normally these settings are defined in
the context of DHCP definitions and therefor these values are not available for configurations if DHCP
service is not defined.
A VLAN bridged WM-AD has an option to define the DHCP behavior for the WM-AD. By default, the
DHCP service is disable although the administrator can elect to have the controller's WM-AD interface
on the VLAN become either the actual DHCP server (enable DHCP) or become the relay agent for
DHCP requests.
To set the name server configuration:
1 From the main menu, click WM-AD Configuration. The WM-AD Configuration screen is
displayed.
2 In the left pane WM Access Domains list, click the WM-AD you want to set the name server
configuration for. The Topology tab is displayed.
3 In the DNS Servers box, type the IP Address of the Domain Name Servers to be used.
4 If applicable, in the WINS box, type the IP address if the DHCP server uses Windows Internet
Naming Service (WINS).
Using a DHCP Relay for the WM-AD
Although this procedure could also apply to any WM-AD type, normally these settings are defined in
the context of DHCP definitions and therefor these values are not available for configurations if DHCP
service is not defined.
Using a DHCP relay forces the Summit WM Controller to forward DHCP requests to an external DHCP
server on the enterprise network. This function bypasses the local DHCP server for the Summit WM
Controller and allows the enterprise to manage IP address allocation to a WM-AD from its existing
infrastructure.
The range of IP addresses assigned to the wireless device users on this WM-AD should also be
designated on the external DHCP server.
