Re: [EFM] EFM-OAM frame fomat

I don't believe an Ethernet OAM frame can be sent with LLC embedded.  My understanding is that the Type field= Slow protocol frame, which precludes carrying embedded LLC PDU. In other words, the OAM PDU is self contained and there is no LLC or higher layer carried within the user data field

Hence, it is not possible to have the last 2 Ethernet frame formats carry an OAM frame:

- 802.3 + LLC (802.2)
- 802.3 + LLC +SNAP

Hi,
 
As you know there are 4 Ethernet frame formats:
 
- Ethernet v2
- 802.3
- 802.3 + LLC (802.2)
- 802.3 + LLC +SNAP
 
 
It seems that the currently defined EFM-OAM frame format is based
on Ethernet v2. What is the EFM-OAM frame format for other Ethernet frame
types?
 
Thanks,
-Shahram
