Saving Syslog Messages - Lenovo RackSwitch G8264 Application Manual

Saving Syslog Messages

© Copyright Lenovo 2016
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
RS G8264(config)# [no] logging log stacking
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:
RS G8264(config)# show logging [swn <configured‐switch‐number>] [{messages |
reverse | severity <0‐7>}]
where:
<configured‐switch‐number>
messages
reverse
severity <0‐7>
For example, to retrieve the last 2000 syslog messages of severity 4 or greater from
switch 3, enter:
RS G8052(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:
RS G8264(config)# copy log {swn <switch number>] stfp | {tftp [address
<address>] [filename <file>]
where:
<switch number>
address
