Description
Use the
tracemac
command to trace a device in a cluster through the specified
destination MAC address or IP address, and to display the path from the current device
to the destination device.
Note:
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.
Examples
# Trace the device that belongs to VLAN 1 through its MAC address 00e0-f032-0005.
