Displaying the Syslog configuration on page 220.
Enabling real-time display of Syslog messages
By default, to view Syslog messages generated by a Brocade device, you need to display the Syslog
buffer or the log on a Syslog server used by the Brocade device.
You can enable real-time display of Syslog messages on the management console. When you enable
this feature, the software displays a Syslog message on the management console when the message is
generated. However, to enable display of real-time Syslog messages in Telnet or SSH sessions, you
also must enable display within the individual sessions.
To enable real-time display of Syslog messages, enter the following command at the global CONFIG
level of the CLI.
device(config)#logging console
Syntax: [no] loggingconsole
This command enables the real-time display of Syslog messages on the serial console. You can enter
this command from the serial console or a Telnet or SSH session.
Enabling real-time display for a Telnet or SSH session
To also enable the real-time display for a Telnet or SSH session, enter the following command from the
Privileged EXEC level of the session.
telnet@device#terminal monitor
Syslog trace was turned ON
Syntax: terminal monitor
Notice that the CLI displays a message to indicate the status change for the feature. To disable the
feature in the management session, enter the terminal monitor command again. The command
toggles the feature on and off.
telnet@device#terminal monitor
Syslog trace was turned OFF
Here is an example of how the Syslog messages are displayed.
telnet@device#terminal monitor
Syslog trace was turned ON
SYSLOG: <9>device, Power supply 2, power supply on left connector, failed
SYSLOG: <14>device, Interface ethernet 6, state down
SYSLOG: <14>device, Interface ethernet 2, state up
Displaying real-time Syslog messages
Any terminal logged on to a Brocade switch can receive real-time Syslog messages when the terminal
monitor command is issued.
