There are no Test to Clear Values for the following error types. The error
types are simply provided as additional data that may prove useful while
troubleshooting.
i. This error occurs when a Layer 1 Transmission error is detected for the
port. Run the Long Test Sequence, and pay particular attention to the
results of the Layer 1 Transmission Error Counter Test (#624).
j. A BRI port supports up to three Terminal Endpoint Identifiers (TEIs). This
error occurs when the switch receives a request for a fourth TEI on a port.
Check the number of endpoints administered for this port.
k. This error occurs when an SPID initialization request is made from an
endpoint and the switch determines that the SPID value is invalid or is a
duplicate of another SPID that is already initialized at Layer 3 on the port.
Check the administration of the endpoints.
l. This error occurs when the circuit pack detects an overflow of its receive
buffers. Run the Long Test Sequence, and pay particular attention to the
results of the Receive First In First Out (FIFO) Overflow Error Counter Test
(#625).
m. This error occurs when the BRI Port Local LAN Loop Around Test (#618)
fails. Run the Long Test Sequence, and pay particular attention to the
results of Test #618.
n. This error most likely occurs when the Terminal Endpoint Identifier (TEI)
administered for the ASAI or AT&T endpoint does not match the TEI
administered in the ASAI or AT&T adjunct. Check the switch
administration of the TEI against that of the adjunct, and make sure that
both are using the same TEI.
o. Indicates that sets on the port do not support Layer 3 initialization. Consult
the Service Set documentation.
System Technician-Demanded Tests:
Descriptions and Error Codes
Always investigate tests in the order presented in the following tables when
inspecting errors in the system. By clearing error codes associated with the
NPE
Crosstalk Test
, for example, you may also clear errors generated from other tests
in the testing sequence.
