• CDP Mandatory TLVs Validation—Check Enable to discard incoming CDP
packets not containing the mandatory TLVs 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 LLDP 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, serial
number, or host name).
• Source Interface—IP address to be used in the TLV of the frames. The
available options are:
Use Default
- —Use the IP address of the outgoing interface.
User Defined
- —Use the IP address of the interface (defined 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 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.
