Only the S5720I-SI, S5720S-SI, S5720-SI, S5735-S, S5735S-S, S5735-S-I, S5730S-EI, S5730-SI, S6720-LI, S6720S-LI, S6720S-SI, and S6720-SI support this function.
For details on the principle and usage scenarios of association between EFM and EFM, see Fault Information Advertisement Between EFM and Other Modules.
Association between EFM and EFM is bidirectional.
You must perform operations on both EFM-enabled devices of a link.
Before configuring association between EFM and EFM, perform the task of Configuring Basic EFM Functions.
The system view is displayed.
The OAM management view is displayed.
Unidirectional association
Run the oam-bind ingress efm interface interface-type interface-number egress efm interface interface-type interface-number command to configure EFM on one link to notify EFM on the other link of faults.
Bidirectional association
Run the oam-bind efm interface interface-type interface-number efm interface interface-type interface-number command to configure EFM on two links to notify each other of faults.
The functions of two commands used to configure association functions in opposite directions are the same as those of the command used to configure the bidirectional association function.
If the oam-bind efm interface interface-type interface-number efm interface interface-type interface-number command is run, two oam-bind ingress efm interface interface-type interface-number egress efm interface interface type interface-number commands used to configure association functions in opposite directions will be displayed in the configuration file.
