Ethping
ethping -i <interface> [-?] [-c count] [-v vlan] [-s size] [-l mdlevel] <target address>
Example: To use CFM Ethernet Ping, a minimal configuration in the Ethernet CFM Interfaces table is required. On the second device, a corresponding configuration is also necessary; however, the MEPID must differ or be unique. In this example, MD-Level 7 is used.

Instead of sending the CFM Ethernet Ping to an Ethernet unicast MAC address, the standardized multicast group can also be used. The structure of the multicast address is as follows: 01:80:C2:00:00:3x. Here, x is a value between 0 and 7 and corresponds to the domain level number for the MEP.
