Appendix A System Event Logging

This appendix describes the entries that may be logged by the system event log. Of particular impor- tance is the log event’s Category – this is the minimum severity level that must be set in order that the event be logged.

Use caution when changing Categories from their default levels. If too many sources have their Category values set too low, the number of messages being logged in a given period can be very large. If too many messages are being logged too rapidly, system performance can be adversely affected.

Most of the events discussed in the following tables are used primarily during troubleshooting and should be turned off in normal operation:

•Table A-1, “System Event,” on page A-2

•Table A-2, “Switchboard Events,” on pag eA-3

•Table A-3, “Nx 56/64 Events,” on page A-3

•Table A-4, “T1 Events,” on page A-4

•Table A-5, “Ethernet Events,” on page A-5

•Table A-6, “ISDN Events,” on page A-5

•Table A-7, “ISDN Cause Code Events,” on page A-7

•Table A-8, “Cause Code Log Entry Location Designations,” on page A-9

•Table A-9, “ISDN L2 Messages,” on page A-9

•Table A-10, “ISDN Call Control Messages,” on page A-9
