Displaying Syslog messages

Displaying Syslog messages
To display the Syslog messages in the device local buffer, enter the show logging command at any
level of the CLI. The following shows an example display output.
device>#show logging
Syslog logging: enabled (0 messages dropped, 0 flushes, 0 overruns)
Buffer logging: level ACDMEINW, 3 messages logged
level code: A=alert C=critical D=debugging M=emergency E=error
Static Log Buffer:
Dec 15 19:04:14:A:Fan 1, fan on right connector, failed
Dynamic Log Buffer (50 entries):
Dec 15 18:46:17:I:Interface ethernet 4, state up
Dec 15 18:45:21:I:Bridge topology change, vlan 4095, interface 4, changed

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
