I have been searching for this for a while and haven't found one yet. I need a Cisco IOS command to send a syslog message or snmp trap whenever an interface that has a CDP neighbor goes down.
Some people have told me just rely on routing protocol neighbor drops, but that isn't really good enough. I have routers that are connected via static, switches, and wireless controllers. All of those devices don't run a routing protocol.
Is there a command to enable CDP syslog? I have searched for this for a while and it seems like such a basic need that Cisco would have already built something for it.
