MSM7xx Controllers Configuration Guide v6.4.0

To receive traffic from users, the controller assigns the Gateway address you specify to its LAN
port.
NOTE: These configuration options do not appear for the default VSC. The default VSC uses the
same settings as defined on the Controller >> Network > Address allocation page.
DHCP relay agent
This option is only available if the controller is currently configured as a DHCP relay agent on the
Controller >> Network > Address allocation page. Refer to “Configuring the DHCP relay agent”
(page 48).
A separate DHCP relay agent can be enabled on each VSC to provide custom addressing to users.
NOTE: These DHCP relay agent options do not appear for the default VSC. The default VSC
uses the same settings as defined on the Controller >> Network > Address allocation page.
VSC data flow
Each VSC provides a number of configurable options, some of which apply exclusively on controlled
APs or the controller. The following diagrams illustrate how traffic from wireless users is handled
by VSC definitions on a controlled AP and controller, and shows the options that apply on each
device. For more on traffic flow, see “Traffic flow for wireless users” (page 221).
