OAM application topology
Configuration procedure: (Omitting SNMP and Log configuration in the following)
Configuration on CE:
CE(config)#interface ethernet 1/0/1
CE (config-if-ethernet1/0/1)#ethernet-oam mode passive
CE (config-if-ethernet1/0/1)#ethernet-oam
CE (config-if-ethernet1/0/1)#ethernet-oam remote-loopback supported
Other parameters use the default configuration.
Configuration on PE:
PE(config)#interface ethernet 1/0/1
PE (config-if-ethernet1/0/1)#ethernet-oam
Other parameters use the default configuration.
Execute the following command when using remote loopback.
PE(config-if-ethernet1/0/1)#ethernet-oam remote-loopback
Execute the following command to make one of OAM peers exiting OAM loopback after complete
detection.
PE(config-if-ethernet1/0/1)# no ethernet-oam remote-loopback
Execute the following command without supporting remote loopback.
CE(config-if-ethernet1/0/1)#no ethernet-oam remote-loopback supported
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
