5.6.2.2.7 logging source

Command: logging source {default|m_shell|sys_event} channel {console|logbuff|

loghost|monitor} [ level {critical|debugging|notifications|warnings}

[state {on|off}]]

no logging source {default|m_shell|sys_event} channel

{console|logbuff| loghost|monitor }

Function: This command is used to add or remove logging source path.

Parameters: m_shell is used to enable shell for logging output path. sys_event is used

to enable logging for important system events, including ports up/down events, topology

changes. default is used to enable logging for all the software modules. channel (console

| logbuff | loghost | monitor) is the output path for logging. console for the console port,

monitor for the user monitor, logbuf for the memory buffer, and loghost for remote

logging host. level (critical | debugging | notifications | warnings) configures the

logging level. state { on | off } is used to enable or disable the logging.

Logging levels are defined as below:

critical - critical logs

debugging - logs for debugging purpose.

notifications - Important information.

warnings - Warning logs.

Command mode: Admin Mode

Default: Logging is delivered to logbuffer by default, with logging level as debugging.

Usage Guide: This command is used to filter logging information at the modules’ level.

For example, the logging for the Driver module can be configured to output to any

supported output path. For logs with its level higher than warnings can be configured to

output to hosts, while logs of lower levels than notifications can be configured to output to

logbuf.

Notice: There only two modules available for the source at the time when the manual is

written. They are:

One is m_shell for logging for all the configuration commands, the log level is notifications.

And the other is sys_event, which is used to monitor all the system events, including

UP/DOWN, STP topology changes, and the state changes of trank ports. The loglevel is

warnings.

Example: Enable logging for the shell module for logs that are delivered to loghost.l And

enable the logging level to be notifications. Enable logging of the shell module to the

logbuff, with the logging level to be debugging.

Switch(Config)# logging source m_shell channel loghost level notifications state on

Switch(Config)# logging source m_shell channel logbuff level debugging state on

Relative Commands: logging on，logging console，logging monitor，logging host，
