• 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 or
serial number).
• 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.
