Configuring System Message Logs
Purpose
Enters global configuration mode.
Logs messages to an internal buffer on the
switch or on a standalone switch or, in the case
of a switch stack, on the active switch.. The
range is 4096 to 2147483647 bytes. The default
buffer size is 4096 bytes.
If a standalone switch or the active switch fails,
the log file is lost unless you previously saved
it to flash memory. See Step 4.
Do not make the buffer size too large
Note
because the switch could run out of
memory for other tasks. Use the
show memory privileged EXEC
command to view the free processor
memory on the switch. However,
this value is the maximum available,
and the buffer size should not be set
to this amount.
Logs messages to a UNIX syslog server host.
host specifies the name or IP address of the host
to be used as the syslog server.
To build a list of syslog servers that receive
logging messages, enter this command more
than once.
Returns to privileged EXEC mode.
Logs messages to a nonconsole terminal during
the current session.
Terminal parameter-setting commands are set
locally and do not remain in effect after the
session has ended. You must perform this step
for each session to see the debugging messages.
