Configuring the UNIX System Logging Facility
When sending system log messages to an external device, you can cause the switch to identify its messages as originating from any of the UNIX syslog facilities.
Beginning in privileged EXEC mode, follow these steps to configure UNIX system facility message logging. This procedure is optional.
Step 1
|
configure terminal
|
Enter global configuration mode.
|
Step 2
|
logging host
|
Log messages to a UNIX syslog server host by entering its IP address.
To build a list of syslog servers that receive logging messages, enter this command more than once.
|
Step 3
|
logging trap level
|
Limit messages logged to the syslog servers.
Be default, syslog servers receive informational messages and lower. See Table 1-3 for level keywords.
|
Step 4
|
logging facility facility-type
|
The default is local7.
|
Step 5
|
end
|
Return to privileged EXEC mode.
|
Step 6
|
show running-config
|
Verify your entries.
|
Step 7
|
copy running-config startup-config
|
(Optional) Save your entries in the configuration file.
|
To remove a syslog server, use the no logging host global configuration command, and specify the syslog server IP address. To disable logging to syslog servers, enter the no logging trap global configuration command.
Table 1-4 lists the UNIX system facilities supported by the software. For more information about these facilities, consult the operator’s manual for your UNIX operating system.
