From: 	Tony Jeffree – Chair, IEEE 802.1 Working Group (tony@jeffree.co.uk) 
Approval: 	Agreed to at IEEE 802.1 Plenary meeting, San Antonio, TX November 2012

Dear Mr. Chen and members of the Metro Ethernet Forum,

The IEEE 802.1 Working Group thanks MEF for the liaison regarding the MIB work being done by the MEF.  Regarding the question on what MIB object is used to trigger the transmission of a LTM by a MEP, your interpretation of IEEE Std 802.1ag-2007 is correct:  a LTM transmission is initiated by a set operation to the dot1agCfmMepTransmitLtmFlags object.  The 802.1 Working Group has initiated a Maintenance Item to note that this is not explicit in the current text and could be clarified in a future Corrigendum, Amendment, or Revision of 802.1Q.

We look forward to continuing cooperation with MEF in the future.
Sincerely,
Tony Jeffree
Chair, IEEE 802.1 Working Group
