Switch Problems
The Event Log records operating events in single- or double-line entries and
serves as a tool to isolate and troubleshoot problems.
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.
N o t e
The Event Log is erased if power to the switch is interrupted or 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 C-6, each Event Log entry is composed of five or six fields,
depending on whether numbering is turned on or not:
