Viewing LLDP Information
12-10
You can view the LLDP messages that are arriving on interfaces in real time
by entering:
Syntax: debug lldp rx [verbose]
If an interface seems to be receiving an undue number of messages, you can
enter the show lldp neighbors interface <interface ID> command to view
information about the device at fault. You should then troubleshoot that
device.
You can also track the LLDP activity of interfaces on the local router. To
monitor the LLDP messages that the router interfaces are transmitting, enter:
Syntax: debug lldp tx [verbose]
If you want to change how often interfaces send messages, you can raise the
minimum transmit interval. (See "Altering LLDP Timers" on page 12-14.)
Entering the debug commands without the verbose option simply informs
you when a LLDP message is sent or received. If you want to see the actual
information in the message, you should add the verbose option. For example:
ProCurve# debug lldp tx verbose
Figure 12-7 displays an example of the verbose debug of an LLDP message.
If you do not want the router to send the information you see displayed, or a
specific portion of this information, you should prevent the interface from
sending the corresponding type of LLDP message. WAN interfaces, in partic-
ular, can compromise a network by transmitting LLDP messages to an
untrusted device. See "Preventing an Interface from Sending Certain LLDP
Messages" on page 12-12.
