Using the Log File
If none of the above suggest a reason as to why Ethernet switching is not properly working, look into the
log file and see if there are any messages that may suggest why switching is not working properly. Use the
show log swlog command to view the system log file. Look for evidence of a system or interface problem
around the time the problem began.
