Configuring CDP Port Settings
Use the Port Settings page to enable or 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.
To define the CDP port settings:
STEP 1 Click Administration > Discovery CDP > Port Settings.
The following fields are displayed:
• Interface—Port identifier.
• CDP Status—CDP publishing option for the port.
• Reporting Conflicts with CDP Neighbors—Displays the status of the
reporting options (Voice VLAN/Native VLAN/Duplex) that are enabled or
disabled on the Edit page.
• No. of Neighbors—Number of neighbors detected.
STEP 2 Select a port and click Edit.
STEP 3 Enter the following information:
• Interface—Select the port to be defined.
• CDP Status—Check Enable to enable 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—Check Enable to send 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—Check Enable to send 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—Check Enable to send 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.
