Chapter 24 Configuring System Message Logging Configuring System Message Logging Command Step 3 logging host Step 4 logging file flash:filename [max-file-size [min-file-size]] [severity-level-number | type] Step 5 end Step 6 terminal monitor Step 7 show running-config Step 8 copy running-config startup-config Purpose Log messages to a UNIX syslog server host. For host, specify the name or IP address of the host to be used as the syslog server. To build a list of syslog servers that receive logging messages, enter this command more than once. For complete syslog server configuration steps, see the "Configuring UNIX Syslog Servers" section on page 24-10. Store log messages in a file in flash memory. • For filename, enter the log message filename. • (Optional) For max-file-size, specify the maximum logging file size. The range is 4096 to 2147483647. The default is 4096 bytes. • (Optional) For min-file-size, specify the minimum logging file size. The range is 1024 to 2147483647. The default is 2048 bytes. • (Optional) For severity-level-number | type, specify either the logging severity level or the logging type. The severity range is 0 to 7. For a list of logging type keywords, see Table 24-3 on page 24-9. By default, the log file receives debugging messages and numerically lower levels. Return to privileged EXEC mode. Log messages to a nonconsole terminal during the current session. Terminal parameter-setting commands are set locally and do not remain in effect after the session has ended. You must perform this step for each session to see the debugging messages. Verify your entries. (Optional) Save your entries in the configuration file. The logging buffered global configuration command copies logging messages to an internal buffer. The buffer is circular, so newer messages overwrite older messages after the buffer is full. To display the messages that are logged in the buffer, use the show logging privileged EXEC command. The first message displayed is the oldest message in the buffer. To clear the contents of the buffer, use the clear logging privileged EXEC command. To disable logging to the console, use the no logging console global configuration command. To disable logging to a file, use the no logging file [severity-level-number | type] global configuration command. Synchronizing Log Messages You can synchronize unsolicited messages and debug privileged EXEC command output with solicited device output and prompts for a specific console port line or virtual terminal line. You can identify the types of messages to be output asynchronously based on the level of severity. You can also configure the maximum number of buffers for storing asynchronous messages for the terminal after which messages are dropped. When synchronous logging of unsolicited messages and debug command output is enabled, unsolicited device output appears on the console or printed after solicited device output appears or is printed. Unsolicited messages and debug command output appears on the console after the prompt for user input OL-8915-01 Cisco Catalyst Blade Switch 3020 for HP Software Configuration Guide 24-5

Chapter 24
Configuring System Message Logging
Configuring System Message Logging
The
logging buffered
global configuration command copies logging messages to an internal buffer. The
buffer is circular, so newer messages overwrite older messages after the buffer is full. To display the
messages that are logged in the buffer, use the
show logging
privileged EXEC command. The first
message displayed is the oldest message in the buffer. To clear the contents of the buffer, use the
clear
logging
privileged EXEC command.
To disable logging to the console, use the
no logging console
global configuration command. To disable
logging to a file, use the
no logging file
[
severity-level-number
|
type
] global configuration command.
Synchronizing Log Messages
You can synchronize unsolicited messages and
debug
privileged EXEC command output with solicited
device output and prompts for a specific console port line or virtual terminal line. You can identify the
types of messages to be output asynchronously based on the level of severity. You can also configure the
maximum number of buffers for storing asynchronous messages for the terminal after which messages
are dropped.
When synchronous logging of unsolicited messages and
debug
command output is enabled, unsolicited
device output appears on the console or printed after solicited device output appears or is printed.
Unsolicited messages and
debug
command output appears on the console after the prompt for user input
Step 3
logging
host
Log messages to a UNIX syslog server host.
For
host
, specify the name or IP address of the host to be used as the
syslog server.
To build a list of syslog servers that receive logging messages, enter this
command more than once.
For complete syslog server configuration steps, see the
“Configuring
UNIX Syslog Servers” section on page 24-10
.
Step 4
logging file flash:
filename
[
max-file-size
[
min-file-size
]]
[
severity-level-number
|
type
]
Store log messages in a file in flash memory.
For
filename
, enter the log message filename.
(Optional) For
max-file-size, s
pecify the maximum logging file size.
The range is 4096 to 2147483647. The default is 4096 bytes.
(Optional) For
min-file-size, s
pecify the minimum logging file size.
The range is 1024 to 2147483647. The default is 2048 bytes.
(Optional) For
severity-level-number | type,
specify either the logging
severity level or the logging type. The severity range is 0 to 7. For a
list of logging type keywords, see
Table 24-3 on page 24-9
. By
default, the log file receives debugging messages and numerically
lower levels.
Step 5
end
Return to privileged EXEC mode.
Step 6
terminal monitor
Log messages to a nonconsole terminal during the current session.
Terminal parameter-setting commands are set locally and do not remain
in effect after the session has ended. You must perform this step for each
session to see the debugging messages.
Step 7
show running-config
Verify your entries.
Step 8
copy running-config startup-config
(Optional) Save your entries in the configuration file.
