Procedure
l In the scenario where a MFR is configured:
1. Check that a PVC is configured on the DTE-side interface.
Run the display fr pvc-info interface serial command in the system view to check
whether there is PVC information.
[Huawei-MFR0/0/0]display fr pvc-info interface MFR
0/0/0
PVC statistics for interface MFR0/0/0 (DTE, physical
UP)
DLCI = 22, USAGE = UNUSED (00000000),
MFR0/0/0
create time = 2007/11/28 12:14:44, status =
ACTIVE
InARP = Enable, PVC-GROUP =
NONE
in packets = 22, in bytes =
994
out packets = 22, out bytes = 950
– If no PVC information is displayed, no PVC exists on the interface. Configure the
PVC on the DCE-side interface. If you are sure that the PVC exists on the DCE-
side interface, you can also configure PVC on the DTE-side interface.
– If the value of the status field is INACTIVE, there is a possibility that no PVC
exists on the DCE-side interface. Configure the PVC on the DCE-side interface.
– If the value of the status field is ACTIVE, the PVC functions properly. Go to step
2.
NOTE
If a sub-interface is configured on the DTE-side interface, configure a DLCI for the sub-
interface.
2. Check that the number of PVCs configured on the DTE-side interface does not exceed
the threshold.
Run the display fr pvc-info command on the DTE-side interface to check the
configured PVCs.
[Huawei-MFR0/0/0]display fr pvc-
info
PVC statistics for interface MFR0/0/0 (DTE, physical
UP)
DLCI = 22, USAGE = UNUSED (00000000),
MFR0/0/0
create time = 2007/11/28 12:14:44, status =
ACTIVE
InARP = Enable, PVC-GROUP =
NONE
in packets = 29, in bytes =
1218
out packets = 29, out bytes =
1160
If the number of configured PVCs has reached the threshold, no more PVCs can be
created. The AR2200-S supports a maximum of 128 PVCs.
