CFM CCM PDUs Forwarding Mode
This window is used to configure the CFM CCM PDU forwarding mode on the Switch. By default the CCM message is
handled and forwarded by software. The software can handle the packet based on behaviour defined by the standard.
Under a strict environment, there may be substantial amount of CCM packets, and it will consume a substantial
amount of CPU resources. To meet the performance requirement, the handling of CCM can be changed to hardware
mode.
