12.4 EFM OAM Troubleshooting 
When using EFM OAM, it occurs the problem, please check whether the problem is resulted 
by the following reasons: 
  Check  whether  OAM entities  of  two peers of link in passive mode.  If so, EFM  OAM 
connection can not be established between two OAM entities. 
  Ensuring SNMP configuration is correct, or else errored event can not be reported to 
network management system. 
  Link does not normally communicate in OAM loopback mode, it should cancel remote 
loopback in time after detect the link performance. 
  Ensuring the used board supports remote loopback function. 
  Port  should  not  configure  STP,  MRPP,  ULPP,  Flow  Control,  loopback  detection 
functions after it  enables  OAM loopback  function,  because OAM remote  loopback 
function and these functions are mutually exclusive.
