Using trace syslog to diagnose problems

The trace command is the main debugging tool for the ERS 8800/8600. To alleviate some
of the overhead and make tracing more efficient, Avaya added Syslog tracing to enhance the
current tracing mechanism. With this enhancement, trace messages transmit out as Syslog
packets to avoid the overhead caused by the traces for displaying the messages on the switch
console and logging to a file. An external entity captures these Syslog trace packets and
decodes them appropriately.
Important:
Note the following points:
• When enabled, the output is not sent to the trace buffer.
• The port must be an inband Ethernet I/O port. This command does not work with the
CPU management port.
