Usage Guidelines
To use this command, you must be in a user group associated with a task group that includes appropriate task
IDs. If the user group assignment is preventing you from using a command, contact your AAA administrator
for assistance.
If Protocol Errors are seen in the output, then the CE device is sending packets to the PE device, but the PE
does not understand those packets. This suggests an incorrect implementation of the E-LMI protocol on the
CE side, or corruption of the packets on the path between the CE and PE. E-LMI packets have a strictly defined
structure in the MEF 16 standard, and any deviation from that results in a protocol error. The PE will not
respond to any packets that are malformed and result in a protocol error.
The Reliability Error counters can indicate that messages are being lost between the PE and CE devices. The
timers in the last block of the output should indicate that messages are being sent and received by the PE
device. Consider the following actions when these Reliability Errors occur:
•
Status Enq Timeouts
—
If this counter is continuously incrementing, it indicates that the Polling Timer
on the CE is configured to a greater value than the PVT configuration on the PE. Status Enquiry messages
will be sent less frequently than the PVT expects them and PVT timeouts occur. Be sure that the value
of the PVT (specified by the
polling-verification-timer
command on the PE) is greater than the Polling
Timer value on the CE device.
•
Invalid Sequence Number
—
Indicates that messages from the PE are not being received by the CE. Be
sure that the correct interface on the CE device is connected to the corresponding E-LMI interface on
the PE device, so that communication can take place. Verify that both interfaces are Up.
•
Invalid Report Type
—
This error can occur under the following conditions:
◦
If the protocol is in the process of a status update and an "E-LMI Check" type of STATUS
ENQUIRY is received by the PE, then the PE ignores the ENQUIRY and records an error.
◦
If the protocol is not in the process of a status update and a "Full Status Continued" type of STATUS
ENQUIRY is received by the PE, then the PE ignores the ENQUIRY and records an error.
If the protocol is in the process of a status update and a "Full Status" type of STATUS ENQUIRY is
received by the PE, then the PE restarts the status update but does not record any error.
