Geetha,
 
draft-ietf-hubmib-efm-mib-03.txt is not expired. As it is under review
by the IESG its validity is extended automatically. A MIB Doctor review
was performed by Dave Perkins, and the recommendations were made
available on the list - please see the archives. The editor is preparing
a new version to answer the comments in the MIB Doctor review. 
 
Regards,
 
Dan

	Hello Dan,
	 
	Thank you very much for response. I will forward my questions to
IEEE 802.3 WG.
	 
	I have come across the draft mib
"draft-ietf-hubmib-efm-mib-03.txt" for 
	Ethernet OAM that expired on September, 2005. 
	 
	Is that MIB standardised (or) Are there any other new draft
versions coming in?
	 
	Thank you in advance.
	 
	Best Regards,
	Geetha.

		Geetha,
		 
		I believe that you are asking questions that are related
to the IEEE 802.3 standards, and not to the Ethernet MIB work that is
being done in the IETF. I suggest that you address your clarification
questions to the IEEE 802.3 Working Group. 
		 
		Best Regards,
		 
		Dan Romascanu

			Subject: [Hubmib] IEEE 802.3ah - EOAM - clause
57 - need clarification on the statements in section 57.2.11.4 &
57.2.11.6

			Section 57.2.11.6:
			=============
			To ensure correct operation, the OAM client
needs to, within one second of 
			receiving a Loopback Control OAMPDU with the
Enable OAM Remote Loopback 
			command:
			a) Set its local_par_action parameter to LB and
the local_mux_action to DISCARD 
			    via OAM_CTL.request service primitive.
			b) Send an Information OAMPDU.  

			Section 57.2.11.4:
			=============
			Since Information OAMPDUs are continually sent
to keep the OAM Discovery process
			from re-starting, the occasional loss of an
Information OAMPDU should not adversely 
			impact the operation of OAM remote loopback
mode. 

			The above 2 statements are conflicting: 
			- first statement insists on sending OAMPDU
within one second to ensure correct operation 
			- second statement says that loss os Information
OAMPDU should not adversely impact 
			   the operation of OAM ermote loopback mode.

			In Remote loopback mode, what will happen if the
remote peer is not responding with 
			an information OAMPDU within a second after
sending a remote loopback command? 
			This is critical as the Multiplexer at the local
DTE will be put in Discard state until an 
			information OAMPDU is received and all the
frames from higher layers will be dropped.
			 
			Clarification on this will be highly
appreciated.

			Thank you.
			 
			Regards,
			Geetha.
