HP MSM7XX User Manual

Network configuration
Address allocation
3-16
You do not have to add this name to your server for it to be resolved. The controller
intercepts all DNS requests it receives. It resolves any request that matches the certificate
host name by returning the IP address assigned to the Internet port. All other DNS requests
are forwarded to the appropriate DNS servers as configured on the Controller > Network >
DNS page.
To summarize, this means that by default, any DNS request by a user that matches
wireless.colubris.com will return the IP address of the controller’s Internet port.
Lease time
Specify the lease time (in seconds) that the controller will assign to all assigned addresses. As
long as a user remains connected their address is automatically renewed when the lease time
expires. If a user disconnects without releasing their address, then the address remains
reserved until the lease time expires. If you have a small address pool and a large user
turnover, setting a long lease time may cause you to run out of addresses even though they
are not really in use.
Logout HTML user on discovery request
When enabled, the controller will log out a client station if a DHCP discovery request is
received from the client station while a DHCP address lease is currently assigned.
This feature is useful when multiple users share the same client station. If a user forgets to
log out before turning off the client station, the next user will have to wait until the lease
expires before being able to log in.
Listen for DHCP requests on
Select the port on which the controller will listen for DHCP requests from client stations.
 LAN port: Listen for requests on the LAN port.
 Client data tunnel: Enable this option when the client data tunnel feature is active on
one or more VSCs, and you want tunneled client stations to be able to receive an IP
address from the controller’s DHCP server.
Controller discovery
Use this option to define controller discovery information for controlled APs. See DHCP
discovery on page 6-8.
Add the IP address for each controller that is active on the network. When working with a
controller team you should add the IP address of each team member.
This list is sent to all devices that request an IP address, encoded as DHCP option 43 (Vendor-
specific information). However, this information is only interpreted by HP ProCurve APs that
are operating in controlled mode. Controlled mode APs use these addresses to connect with
the controllers in the order that they appear in the list.
DHCP relay agent
The controller provides a flexible DHCP relay implementation. It can listen for requests on
the LAN port or client data tunnel and forward them to a DHCP via any of the controller’s
physical or logical interfaces.
