Configuring System Message Logging Chapter 24 Configuring System Message Logging Step 3 Step 4 Step 5 Step 6 Command Purpose logging history size number Specify the number of syslog messages that can be stored in the history table. The default is to store one message. The range is 0 to 500 messages. end Return to privileged EXEC mode. show running-config Verify your entries. copy running-config startup-config (Optional) Save your entries in the configuration file. 1. Table 24-3 lists the level keywords and severity level. For SNMP usage, the severity level values increase by 1. For example, emergencies equal 1, not 0, and critical equals 3, not 2. When the history table is full (it contains the maximum number of message entries specified with the logging history size global configuration command), the oldest message entry is deleted from the table to allow the new message entry to be stored. To return the logging of syslog messages to the default level, use the no logging history global configuration command. To return the number of messages in the history table to the default value, use the no logging history size global configuration command. Configuring UNIX Syslog Servers The next sections describe how to configure the UNIX server syslog daemon and how to define the UNIX system logging facility. 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. This procedure is optional. 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 decide what options must be added to or removed from the syslog command line to enable logging of remote syslog messages. Step 1 Step 2 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 24-4 on page 24-11 for information on the facilities. The debug keyword specifies the syslog level; see Table 24-3 on page 24-9 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 24-10 Cisco Catalyst Blade Switch 3020 for HP Software Configuration Guide OL-8915-01
