[EFM] Question regarding OAM in 802.3ah D1.3
Hi,
802.3ah section 57
says that the OAM defined is for single link (or emulated link), and should not
be forwarded by bridges/switches.
My question is, in
case of Ethernet over SONET transport (GFP + Virtual concatenation), should the
OAMPDU be terminated at the EOS device or it should be transparently
transported?
Consider this
example:
OLT1 -------------- ONU 1------------------ ONU 2
------------ OLT 2
Ethernet SONET Ethernet
Assume OLT1 and OLT2
are the customer equipments and ONU1 and ONU2 are provider
transport equipments
that transport Ethernet over SONET (but don't do any
switching/bridging).
In this case should
ONU1 terminate OAMPDUs from OLT1 or it should sent them transparently to
OLT2?
In other words is
OLT1--ONU1 considered a single link? what about ONU1 to ONU2, is this also a
link?
Thanks in
advance,
