Ta b l e 4 - 4 Controller Management or Operator-Defined Interface Parameters
Parameter Description
VLAN Identifier Virtual LAN assigned to the interface.
IP Address The IP address of the Interface.
Netmask Interface subnet mask.
Gateway Interface gateway router IP address.
Port Number The controller physical port for this interface.
Note The port number for a Cisco NMWLC6 controller is always
displayed as “1” as the external port is not used.
Primary Port Number The primary port for Cisco 4400 Series Wireless LAN Controllers.
Secondary Port Number The secondary port for Cisco 4400 Series Wireless LAN Controller.
If the primary port shuts down, all the interfaces on the primary port
are moved to the secondary port. When the primary port becomes
active again, the interfaces are moved back to the primary port.
AP Management Select this checkbox to enable AP Management.
A single AP management interface will result in all the APs
communicating with the controller over a single gigabit port. This
leads to increased traffic on the port.
To avoid this, if AP Management option is enabled, you can
designate any dynamic interface configured on the controller as an
AP interface. As a result, a group of access points or each access
point can be assigned a dynamic interface over which it can transmit
data.
Note This feature is present in Cisco 4400 Series Wireless LAN
Controllers only.
Primary DHCP Server The interface uses this DHCP server first to obtain an IP address.
Secondary DHCP Server The interface uses this DHCP server as a backup to obtain an
IP address.
ACL Name Any of the Access Control Lists currently displayed on the Access
Control Lists page.
