Frame Relay PVC Problems
Table 8-4. Frame Relay PVC Problems
Symptom
Possible Cause Solutions
No receipt or
transmission of data
Cross Connection of the
DLCIs are configured
incorrectly.
Verify the PVC connections
and DLCIs by checking the
network-discovered DLCIs on
the LMI Reported DLCIs screen.
DLCI is inactive on the
frame relay network.
H Verify that the DLCI(s) is
active on the LMI Reported
DLCIs screen. If the DLCI(s) is
not active, contact the service
provider.
H Verify the LMI Reported DLCI
field on the Interface Status
screen.
DTE is configured
incorrectly.
Check the DTE’s configuration.
LMI is not configured
properly for the DTE or
network.
Configure LMI characteristics to
match those of the DTE or
network.
LMI link is inactive. Verify that the LMI link is active
on the network; the Status Msg
Received counter on the Network
Frame Relay Performance
Statistics screen increments.
Losing Data
Frame relay network is
experiencing problems.
Run PVC Loopback and Pattern
tests to isolate the problem, then
contact the service provider.
Out of Sync If Monitor Pattern was
selected, it means the test
pattern generator and
receiver have not yet
synchronized.
CIR settings for the units at
each end are mismatched.
If the message persists, it
means that 5 packets out of
25 are missing or are out of
sequence.
H Verify that the unit at the
other end is configured to
Send Pattern.
Correct unit configurations.
H Correct the CIR setting so
both units are configured the
same.
H Check the line’s error rate –
the physical line quality.
Contact the service provider.
