of a switch stack, on the active switch.. The
Device(config)# logging buffered 8192
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 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.
