Cat4000−c
show time
This command displays the day of the week/month/year and the time in a 24−hour format. This verifies the
operation of the system clock, but also is a reminder that system log messages carry a timestamp. Make sure
to set the time accurately or sync the switch to Network Time Protocol (NTP).

Refer to the show time command for more information.
show logging buffer 1023
This command displays system messages from the internal buffer. The show logging buffer command only
gives you the last 20 system messages, while if you add the 1023 keyword, this gives you the last 1023
messages. Many of these messages are strictly informational. Others can contain clues as to the nature of the
problem, whether it is a hardware problem, switch crash, or software problem. When you compare the logs on
several pieces of equipment, verify that the time stamps are correct and issue the show time command.
For example, these types of messages are informational:
2002 Jan 06 16:07:04 %DTP−5−TRUNKPORTON:Port 2/23 has become dot1q trunk
2002 Jan 06 16:07:08 %PAGP−5−PORTTOSTP:Port 2/21 joined bridge port 2/21−24
A message like this one indicates a hw/sw incompatibility:
Module 6 is not supported (46)
A message like this one can indicate a hardware failure:
EARL−3−LTL: Failure to set LTL for module [DEC]
Refer to Messages and Recovery Procedures for a listing of system messages. Use the Error Message
Decoder, Bug Toolkit, and other resources described under the Prerequisites section in this document. Also,
refer to Common CatOS Error Messages on Catalyst 4000 Series Switches for more information.
Refer to the show logging buffer 1023 command for more information:
