14.4 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.
