15.11 Configuring MAC Ping

Overview
MAC ping provides a method of monitoring performance and detecting errors at the MAC
layer. It determines link-layer connectivity by sending and receiving EOAM MAC ping
packets.
OAM information contained in IEEE802.3 is called Ethernet Operation, Administration and
Maintenance (EOAM). EOAM provides a ping mechanism for the data link layer.
1. A router sends an Echo Request packet with a specific destination MAC address.
The OAM sub-layer sends this ping request packet as an OAM Protocol Data Unit
(OAMPDU).
2. After receiving this Echo Request packet, the receiver generates an Echo an Echo
Response OAMPDU.
EOAM-based MAC ping network structure is shown in

Figure 15-20 MAC Ping Network Structure

MAC ping supports ping from CE1 to CE2, from PE1 to PE2, from PE1 to CE2, and
from CE1 to PE2. The parameters in ping commands sent from a CE and from a PE
are different.
The following takes ping from CE1 to CE2 and from PE1 to PE2 as examples to describe
the procedures.
l
Ping from CE1 to CE2
CE1 sends a MAC-layer ping request which contains an egress interface and a
destination MAC address. When receiving the request packet, CE2 sends a reply
packet. If CE1 receives the reply packet within a specified period, the link layer is
operating properly.
l Ping from PE1 to PE2
PE1 sends a MAC-layer ping request which contains a destination MAC address,
Virtual Private LAN Service (VPLS) name and peer ID. When receiving the request
