Brocade Communications Systems 6650 manual Retaining Syslog messages after a soft reboot

10 Syslog service configuration

Brocade(config)#ip show-service-number-in-log

Syntax: [no] ip show-service-number-in-log

Retaining Syslog messages after a soft reboot

You can configure the device to save the System log (Syslog) after a soft reboot (reload command).

Syslog reboot configuration considerations

•If the Syslog buffer size was set to a different value using the CLI command logging buffered, the System log will be cleared after a soft reboot, even when this feature (logging persistence) is in effect. This will occur only with a soft reboot immediately following a Syslog buffer size change. A soft reboot by itself will not clear the System log. To prevent the system from clearing the System log, leave the number of entries allowed in the Syslog buffer unchanged.

•This feature does not save Syslog messages after a hard reboot. When the Brocade device is power-cycled, the Syslog messages are cleared.

•If logging persistence is enabled and you load a new software image on the device, you must first clear the log if you want to reload the device. (Refer to “Clearing the Syslog messages from the local buffer” on page 242.)

To configure the device to save the System log messages after a soft reboot, enter the following command.

Brocade(config)#logging persistence

Syntax: [no] logging persistence

Enter no logging persistence to disable this feature after it has been enabled.

Clearing the Syslog messages from the local buffer

To clear the Syslog messages stored in the local buffer of the Brocade device, enter the clear logging command.

Brocade#clear logging

Syntax: clear logging
