Properties

CDP Status

Select to enable CDP on the device.

CDP Frames Handling

If CDP is not enabled, select the action to be taken if a packet that matches the selected criteria is received:

• Bridging—(VLAN-aware flooding) Forwards the packet based on the VLAN

• Filtering—Deletes the packet

• Flooding—(VLAN-unaware flooding) Forwards incoming CDP packets to all the ports excluding the ingress ports

CDP Voice VLAN Advertisement

Select to enable the device to advertise the voice VLAN in CDP on all of the ports that are CDP enabled, and are member of the voice VLAN.

CDP Mandatory TLVs Validation

If selected, incoming CDP packets not containing the mandatory TLVs are discarded and the invalid error counter is incremented.

CDP Version

Select the version of CDP to use.

CDP Hold Time

Amount of time that CDP packets are held before the packets are discarded, measured in multiples of the TLV Advertise Interval. For example, if the TLV Advertise Interval is 30 seconds, and the Hold Multiplier is 4, then the CDP packets are discarded after 120 seconds. The following options are possible:

• Use Default—Use the default time (180 seconds)

• User Defined—Enter the time in seconds.

CDP Transmission Rate

The rate in seconds at which CDP advertisement updates are sent. The following options are possible:

• Use Default—Use the default rate (60 seconds)

• User Defined—Enter the rate in seconds.

Device ID Format

Select the format of the device ID (MAC address or serial number, hostname).

Source Interface

IP address to be used in the TLV of the frames. The following options are possible:

• Use Default—Use the IP address of the outgoing interface.

• User Defined—Use the IP address of the interface (in the Interface field) in the address TLV.

Interface

IF User Defined was selected for Source Interface, select the interface.

Syslog Voice VLAN Mismatch

Check 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 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 to send a SYSLOG message when duplex information is mismatched. This means that the duplex information in the incoming frame does not match what the local device is advertising.
