z When using the destination IP address to trace a device, the switch looks up the ARP entry
corresponding to the IP address, and then looks up the MAC address entry according to the ARP
entry.
z If the queried IP address has a corresponding ARP entry, but the corresponding MAC address of
the IP address does not exist in the MAC address table, the trace of the device fails.
z To trace a specific device using the tracemac command, make sure that all the devices passed
support the tracemac function.
z To trace a specific device in a management VLAN using the tracemac command, make sure that
all the devices passed are within the same management VLAN as the device to be traced.
