Synchronize Log Messages
You can configure a terminal line to hold all logs until all command inputs and outputs are complete so that
log printing does not interfere when you are performing management tasks. Log synchronization also
filters system messages for a specific line based on severity level and limits number of messages that are
printed at once.
Display the logging synchronous configuration using the
show config command from LINE mode.
Enable Timestamp on Syslog Messages
Syslog messages, by default, do not include a time/date stamp stating when the error or message was
created. To have FTOS include a timestamp with the syslog message:
Display your configuration using the command
show running-config logging from EXEC Privilege
mode, as shown in Figure 4-3.
