L2CPD System Log Messages
This chapter describes messages with the L2CPD prefix. They are generated by the Layer 2 Control Protocol process (l2cpd), which supports the transmission of control messages for Layer 2 spanning tree protocols in a Layer 2 bridge environment.
L2CPD_ASSERT
System Log Message
Assertion failed for executable-name (PID pid) at line line-number in file 'source-filename': message
Description
The source code for the Layer 2 Control Protocol process (l2cpd) includes internal self-consistency tests. The l2cpd process with the indicated executable name and process ID (PID) terminated because the indicated test failed at the indicated line number in the indicated source file. The process created a diagnostic core file for analysis by technical support personnel.
Type

Severity
error
Facility
LOG_DAEMON
Cause
Messages that immediately follow this message in the system log might provide information about possible causes.
Action
Contact a technical support representative, and be ready to provide the list of messages and the diagnostic core file, if requested.
L2CPD_ASSERT_SOFT
System Log Message
Assertion failed for executable-name (PID pid) at line line-number in file 'source-filename' (message); process continued running
Description
The source code for the Layer 2 Control Protocol process (l2cpd) includes internal self-consistency tests. The l2cpd process with the indicated executable name and process ID (PID) terminated because the indicated type of check failed at the indicated line number in the indicated source file. The process continued to run, but created a diagnostic core file for analysis by technical support personnel.
