Saving Syslog Messages
By default, syslog messages on each member of a stack are saved to flash memory
on that stack member. You may want to preserve stacking ‐ related errors. To
accomplish this, in console mode, use the following command:
The master switch can display the syslog messages originated on any stack
member as long as the specified stack element is currently an active member of the
stack using the command:
where:
For example, to retrieve the last 2000 syslog messages of severity 4 or greater from
switch 3, enter:
CN 4093(config)# show logging swn 3 severity 4
To retrieve the contents of the log files stored on flash on a specified switch in the
stack and copy that information to an external host using the specified protocol
(SFTP or TFTP). In case the feature of saving log to flash is disabled, this command
must be rejected.
To copy syslog content to an external host using SFTP or TFTP, use the command:
where:
CN 4093(config)# [no] logging log stacking
CN 4093(config)# show logging [swn
<configured ‐ switch ‐ number>

|reverse|severity
<0 ‐ 7>

<configured ‐ switch ‐ number> The configured switch number. If no number is
supplied, the command applies to the master
switch.
