l2 traceroute is limited to a l3 domain. It is limited to an L2 broadcast domain. You cannot go across the subnet.

  • Can you please provide more details? Normally MAC address table entries are aged out by the switch. Some products allow for the learnt addresses to stay sticky on the switch - this works only if the product supports it AND you have access to configure such feature on the switch. – Prem Oct 04 '18 at 07:52
