Sending Syslog Messages To The Log Buffer - Cisco 7604 Configuration Manual

Chapter 25 Monitoring the Firewall Services Module
Viewing Syslog Messages in the Current Session
To enable logging in the current session, perform the following steps:
After you log in to the FWSM, enable logging for the current session by entering the following
Step 1
command:
hostname# terminal monitor
This command enables logging only for the current session. If you log out, and then log in again, you
need to reenter this command.
Step 2 To disable logging for the current session, enter the following command:
hostname(config)# terminal no monitor

Sending Syslog Messages to the Log Buffer

If configured as an output destination, the log buffer serves as a temporary storage location for syslog
messages. New messages are appended to the end of the listing. When the buffer is full, (that is, when
the buffer wraps), old messages are overwritten as new messages are generated, unless you configure the
FWSM to save the full buffer to another location.

To enable the log buffer as a log output destination, enter the following command:
hostname(config)# logging buffered {severity_level | message_list}
Where the severity_level argument specifies the severity levels of messages to be sent to the buffer. You
can specify the severity level number (0 through 7) or name. For severity level names, see the
Levels" section on page
syslog messages for severity levels 3, 2, 1, and 0.
The message_list argument specifies a customized message list that identifies the syslog messages to
