MTS 2 and MTS 4 Installation, Configuration and Basic Service Manual
should be inspected in order to determine the stability of the two PVCs as determined by the LMI
link management protocol. If there is indication of rapid transitioning of the states of the PVCs,
or the two PVCs are indicated as inactive - special attention should be given to the DLCI values
displayed. If this is correct, this indicates a problem with the LMI layer.
SC) status lmi
LMI frames transmitted
LMI frames received
Number of PVC state changes
Number of status inquiries tx
Number of status responses rx
Number of full status inquiries
Number of full status rx
Current primary PVC state
Current backup PVC state
Number of discards when disabled
The frames transmitted and the frames received counters should be incrementing between successive
invocations of status lmi . If the received counter is not incrementing, this indicates that the remote
equipment is not responding to LMI enquiry packets transmitted by the Site Controller - the problem
is probably external to the Site Controller. However, if the receive counter is incrementing, it would
indicate a configuration issue, either with the LMI configuration, or with the configuration of the DLCI's
for the PVCs, check the DLCI numbers displayed by using the status fr command for the DLCI
numbering, and use the display config command to verify the configuration for LMI.

CRTP enable
CRTP context state packet time
CRTP session timeout
LMI enable
LMI full status polling counter (n391)
LMI LIV time (t391)
LMI error threshold (n392)
LMI monitored events count (n393)
Type of Service Latency Time
Frame relay fragmentation size (bytes)
Note that if LMI has been disabled in the Site Controller's configuration, no LMI exchanges will
take place, and the two PVCs will be marked as permanently active. In normal configurations
this may be as a result of an unintended configuration error.
