You also can specify the IP address or host name of up to six Syslog servers. When you specify a Syslog server,
the Foundry device writes the messages both to the system log and to the Syslog server.
Using a Syslog server ensures that the messages remain available even after a system reload. The Foundry
device’s local Syslog buffer is cleared during a system reload or reboot, but the Syslog messages sent to the
Syslog server remain on the server.
The Syslog service on a Syslog server receives logging messages from applications on the local host or from
devices such as a Layer 2 Switch or Layer 3 Switch. Syslog adds a time stamp to each received message and
directs messages to a log file. Most Unix workstations come with Syslog configured. Some third party vendor
products also provide Syslog running on NT.
Syslog uses UDP port 514 and each Syslog message thus is sent with destination port 514. Each Syslog
message is one line with Syslog message format. The message is embedded in the text portion of the Syslog
format. There are several subfields in the format. Keywords are used to identify each subfield, and commas are
delimiters. The subfield order is insensitive except that the text subfield should be the last field in the message.
All the subfields are optional.
Displaying Syslog Messages
To display the Syslog messages in the device’s local buffer, enter the following command at any level of the CLI:
For information about the Syslog configuration information, time stamps, and dynamic and static buffers, see
“Displaying the Syslog Configuration” on page A-4.
Enabling Real-Time Display of Syslog Messages
By default, to view Syslog messages generated by a Foundry device, you need to display the Syslog buffer or the
log on a Syslog server used by the Foundry 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.
When you enable the feature, the software displays Syslog messages on the serial console when they occur.
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:
FESX424 Router(config)# logging console
Syntax: [no] logging console
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.
FESX424 Router> 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:
