Usage Guidelines This command displays the state of syslog error and event logging, including host addresses, and which logging destinations (console, monitor, buffer, or host) logging is enabled. This command also displays Simple Network Management Protocol (SNMP) logging configuration parameters and protocol activity.
This command will also display the contents of the standard system logging buffer, if logging to the buffer is enabled. Logging to the buffer is enabled or disabled using the [no] logging buffered command. The number of system error and debugging messages in the system logging buffer is determined by the configured size of the syslog buffer. This size of the syslog buffer is also set using the logging buffered command.
To enable and set the format for syslog message timestamping, use the service timestamps log command.
