Description Allows the facility MEP to move from alarming only to network actionable function. This means a facility
MEP will not merely report the defect conditions but will be able to action based on the transition of the
MEP state. Without this command the facility MEP will only monitor and report and conditions of the MEP
do not affect related services.
Default no facility-fault
tunnel-fault
Syntax tunnel-fault {accept | ignore}

Description Allows the individual service SAPs to react to changes in the tunnel MEP state. When tunnel-fault accept is
configured at the service level, the SAP will react according to the service type, Epipe will set the opera-
tional flag and VPLS, IES and VPRN SAP operational state will become down on failure or up on clear.
This command triggers the OAM mapping functions to mate SAPs and bindings in an Epipe service as well
as setting the operational flag. If AIS generation is the requirement for the Epipe services this command is
not required. See the ais-enable command under the config>service>epipe>sap>eth-cfm>ais-enable con-
text for more details. This works in conjunction with the tunnel-fault accept on the individual SAPs. Both
must be set to accept to react to the tunnel MEP state. By default the service level command is “ignore” and
the SAP level command is “accept”. This means simply changing the service level command to “accept”
will enable the feature for all SAPs. This is not required for Epipe services that only wish to generate AIS on
failure.
Parameters accept — Share fate with the facility tunnel MEP
ignore — Do not share fate with the facility tunnel MEP
Default ignore (Service Level)
accept (SAP Level for Epipe and VPLS)
