Editing CDP Interface Settings

The Interface Settings page allows administrators to enable/disable CDP per port. Notifications can also be triggered when there are conflicts with CDP neighbors. The conflict can be Voice VLAN data, Native VLAN, or Duplex.

By setting these properties it is possible to select the types of information to be provided to devices that support the LLDP protocol.

The LLDP-MED TLVs to be advertised can be selected in the LLDP MED Interface Settings page.

To define the LLDP interface settings:

  1. Click Administration > Discovery - CDP > Interface Settings. The Interface Settings page opens.
  2. This page displays the following CDP information for each interface.

    • CDP Status--CDP publishing option for the port.
    • Reporting Conflicts with CDP Neighbors--Displays the status of the reporting options that are enabled/disabled in the Edit page.
    • No. of Neighbors--Number of neighbors detected.

    The bottom of the page has four buttons:

    • Copy Settings--Select to copy a configuration from one port to another.
    • Edit--Fields explained in Step 2 below.
    • CDP Local Information Details--Takes you to the Administration > Discovery - CDP > CDP Local Information page.
    • CDP Neighbor Information Details--Takes you to the Administration > Discovery - CDP > CDP Neighbor Information page.
  3. Select a port and click Edit. The Edit CDP Interface Settings page opens.
  4. This page provides the following fields:

    • Interface--Select the interface to be defined.
    • CDP Status--Select to enable/disable the CDP publishing option for the port.

    NOTE     The next three fields are operational when the switch has been set up to send traps to the management station.

    • Syslog Voice VLAN Mismatch--Select to enable the option of sending a SYSLOG message when a voice VLAN mismatch is detected This means that the voice VLAN information in the incoming frame does not match what the local device is advertising.
    • Syslog Native VLAN Mismatch--Select to enable the option of sending a SYSLOG message when a native VLAN mismatch is detected. This means that the native VLAN information in the incoming frame does not match what the local device is advertising.
    • Syslog Duplex Mismatch--Select to enable the option of sending a SYSLOG message when duplex information mismatch is detected. This means that the duplex information in the incoming frame does not match what the local device is advertising.
