Parameters
by-mac: Specifies to trace a device through the specified destination MAC address.
mac-address: MAC address of the device to be traced.
vlan vlan-id: Specifies to trace a device in the specified VLAN. vlan-id ranges from 1 to
4094.

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:
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.
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.
To trace a specific device using the tracemac command, make sure that all the
devices passed support the tracemac function.
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.
