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 eth-oam enable|disable on page 72 for more information.
