Recommended Troubleshooting Procedure
RDI alarm , raised on MEP AID
indicates that the last CCM
received by this MEP from some
remote MEP contained the RDI
bit.
AID = MEP
Remote Defect Indication (RDI)
bit informs that the MEP
originating this indication
doesn't receive CCM messages
from at least one of the MEPs in
the same MA (MEG). The
absence of RDI in a CCM
indicates that the transmitting
MEP is receiving CCMs from all
configured MEPs.
Use CFM loopback toward each MEP in MA/MEG to discover
the problematic MEP. In some cases (i.e. Network load or
NE load of the CCM messages originator/terminator), RDI is
an indication of awkward CFM configuration (i.e. too heavy
traffic is generated at end point, or CFM traffic is congested
with Service traffic in network). For this case, increase CCM
interval (up to 10 min) or increase CCM Priority (up to 7).
This may help resolve the problem.
