Configuring Ports

Configuring Ports

Configuring Ports (GUI)

The controller’s ports are configured with factory-default settings designed to make the controllers’ ports operational without additional configuration. However, you can view the status of the controller’s ports and edit their configuration parameters at any time.

    Step 1   Choose Controller > Ports to open the Ports page.

    This page shows the current configuration for each of the controller’s ports.

    If you want to change the settings of any port, click the number for that specific port. The Port > Configure page appears.


    If the management and AP-manager interfaces are mapped to the same port and are members of the same VLAN, you must disable the WLAN before making a port-mapping change to either interface. If the management and AP-manager interfaces are assigned to different VLANs, you do not need to disable the WLAN.


    The number of parameters available on the Port > Configure page depends on your controller type.

    The following show the current status of the port:

    • Port Number—Number of the current port.

    • Admin Status—Current state of the port. Values: Enable or Disable

    • Physical Mode—Configuration of the port physical interface. The mode varies by the controller type.

    • Physical Status—The data rate being used by the port. The available data rates vary based on controller type.

      • 2500 series - 1 Gbps full duplex

      • WiSM2 - 10 Gbps full duplex

      • 7500 series - 10 Gbps full duplex

    • Link Status—Link status of the port. Values: Link Up or Link Down

    • Link Trap—Whether the port is set to send a trap when the link status changes. Values: Enable or Disable

    • Power over Ethernet (PoE)—If the connecting device is equipped to receive power through the Ethernet cable and if so, provides –48 VDC. Values: Enable or Disable


      Some older Cisco access points do not draw PoE even if it is enabled on the controller port. In such cases, contact the Cisco Technical Assistance Center (TAC).

    The following is a list of the port’s configurable parameters.

    1. Admin Status—Enables or disables the flow of traffic through the port. Options: Enable or Disable Default: Enable.


      When a primary port link goes down, messages may get logged internally only and not be posted to a syslog server. It may take up to 40 seconds to restore logging to the syslog server.

    2. Physical Mode—Determines whether the port’s data rate is set automatically or specified by the user. The supported data rates vary based on the controller type. Default: Auto.

    3. Link Trap—Causes the port to send a trap when the port’s link status changes. Options: Enable or Disable Default: Enable.

    Step 2   Click Apply.
    Step 3   Click Save Configuration.
    Step 4   Click Back to return to the Ports page and review your changes.
    Step 5   Repeat this procedure for each additional port that you want to configure.
