Ethernet OAM Handling Test
Ethernet OAM Handling Test
The Ethernet OAM handling test listens for Ethernet OAM messages in both
Ethernet II and 802.3 LLC/SNAP frame format and responds in the received
format.
No VLAN ID checking is done. The Ethernet OAM feature responds with
VLAN parameters of the received packet. In addition, no MEG-level
discrimination is done, which allows the BV10 to operate in promiscuous
mode (the unit operates as a MEP at multiple levels without any MEG-level
configuration).
Ethernet OAM handling can be globally enabled (default) or disabled. Refer
to
on page 72 for more information.
The BV10 listens for and responds to the following Ethernet OAM
messages:
Loopback
The BV10 responds to Unicast OAM Loopback messages when all of
the following criteria are met:
Global Ethernet OAM handling is enabled (default).
Destination MAC address equals the MAC address of the Test port.
EtherType is 0x8902.
OpCode is 3 (LBM).
