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
Note
large 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.
Stores log messages in a file in flash memory
on a standalone switch or, in the case of a
switch stack, on the active switch .
