Chapter 23 Configuring System Message Logging Configuring System Message Logging Logging Messages to a UNIX Syslog Daemon Before you can send system log messages to a UNIX syslog server, you must configure the syslog daemon on a UNIX server. Log in as root, and perform these steps: Note Some recent versions of UNIX syslog daemons no longer accept by default syslog packets from the network. If this is the case with your system, use the UNIX man syslogd command to determine what options must be added to or removed from the syslog command line to enable logging of remote syslog messages. Step 1 Step 2 Step 3 Add a line such as the following to the file /etc/syslog.conf: local7.debug /usr/adm/logs/cisco.log The local7 keyword specifies the logging facility to be used; see Table 23-4 on page 23-12 for information on the facilities. The debug keyword specifies the syslog level; see Table 23-3 on page 23-9 for information on the severity levels. The syslog daemon sends messages at this level or at a more severe level to the file specified in the next field. The file must already exist, and the syslog daemon must have permission to write to it. Create the log file by entering these commands at the UNIX shell prompt: $ touch /var/log/cisco.log $ chmod 666 /var/log/cisco.log Make sure the syslog daemon reads the new changes: $ kill -HUP `cat /etc/syslog.pid` For more information, see the man syslog.conf and man syslogd commands on your UNIX system. 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: Step 1 Step 2 Command configure terminal logging host Step 3 logging trap level Purpose Enter global configuration mode. 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. Limit messages logged to the syslog servers. Be default, syslog servers receive informational messages and lower. See Table 23-3 on page 23-9 for level keywords. 78-14982-01 Catalyst 2950 Desktop Switch Software Configuration Guide 23-11
