Ethernet OAM is a set of protocols which include mechanisms for detecting and localizing faults, and monitoring 
Ethernet based networks.
Specifically, there are two parts:
1) Link Layer OAM: standarized in IEEE 802.3, clause 57
2) Service Layer OAM: defined in IEEE 802.1 ag, and ITU-T Y.1731
 
Does Wireshark already support these protocols?

Top-of-trunk Wireshark and, as far as I know, Wireshark 1.4.x include a dissector for the OAM "slow protocol" - that's 
the "Link Layer OAM" protocol - and for the IEEE 802.1ag Connectivity Fault Management(CFM) protocol - that's the 
"Service Layer OAM" protocol.
