Management and Configuration Guide K/KA/KB.15.15

Using the Event Log for troubleshooting switch problems
The Event Log records operating events in single- or double-line entries and serves as a tool to
isolate and troubleshoot problems.
Starting in software release K.13.xx, the maximum number of entries supported in the Event Log
is increased from 1000 to 2000. Entries are listed in chronological order, from the oldest to the
most recent.
Once the log has received 2000 entries, it discards the oldest message each time a new message
is received. The Event Log window contains 14 log-entry lines. You can scroll through it to view
any part of the log.
NOTE: The Event Log is erased if power to the switch is interruptedor if you enter the boot
system command. The contents of the Event Log are not erased if you:
• Reboot the switch by choosing the Reboot Switch option from the menu interface.
• Enter the reload command from the CLI.
Event Log entries
As shown in Figure 202 (page 382), each Event Log entry is composed of six or seven fields,
depending on whether numbering is turned on or not:
