4.4.2.11 OAM
For an explanation of the OAM configuration, please refer to section 4.4.1.8 of
the User LAN port configuration menu.
4.4.2.12 Link Loss Forwarding
Link Loss Forwarding enables the port state to reflect the status of the full end to
end link status rather than simply the cabled connection between local link
partners.
When a port enters the Link Loss Forwarding alarm state, the port will be forced
to the Link Down state such that the attached equipment will see there is a
problem with this network connection allowing for protocols such as RSTP or
LACP to remove this link from their network map and enable link restoration by
alternative backup links if available.
The Link Loss may be forwarded from:
WAN
If the WAN port is down then force the User Port to the
Down state.
Flow
The end to end flow state is determined using the CFM
Connectivity messages and if these messages are not being
received, the link will be forced down.
4.4.2.13 Counters
