HP Probe-Speciﬁc Events/Traps

In addition to traps generated by alarms that you conﬁgure, an HP probe

will send a trap to the management station whenever the following

occurs:

● The probe is warm-started.

● Someone attempts to contact the probe with an incorrect community

string. Note that the trap does not include an indication of the offend-

ing management station; however, this information can be viewed in

the RMON Log utility, discussed on page 515.

● The probe detects duplicate IP addresses; that is, the probe sees what

appears to be two stations on the network using the same IP addresses.

(LanProbes only.)

● The probe detects a host whose IP address has changed. (LanProbes

only.) If the probe detects that the same device has changed its IP

address three times, it assumes the device is a router and does not send

any additional address-changed traps for this device (unless the probe

is restarted).

For OpenView NNM, these traps are logged in the event category called

HP NetMetrix Events.
