Configuring Connectivity Fault Management

To configure CFM between the microwave outdoor unit (ODU) and the router, complete the following

steps:

Note For a ring topology, you should configure CFM between the microwave ODU and the router. You must

configure two VLANs to the two microwave ODUs, to process the vendor specific message (VSM) and

trigger the Embedded Event Manager (EEM).
