Troubleshooting

Using Logging To Identify Problem Sources

Configuring the Switch To Send Debug Messages to One or More

SyslogD Servers. Use the logging command to configure the switch to send Syslog messages to a SyslogD server, or to remove a SyslogD server from the switch configuration.

Syntax: [no] logging < syslog-ip-address facility < facility-name >>

<syslog-ip-address >

If there are no SyslogD servers configured, logging enters a SyslogD server IP address and automatically enables Syslog logging to the server. If at least one SyslogD server is already configured and Syslog logging has been disabled, you can still use logging < syslog-ip­ addr > to add another SyslogD server, but Syslog logging remains disabled until you re-enable it with the debug destination logging command. While Syslog logging is enabled, the switch attempts to send Syslog messages to all configured SyslogD server addresses, and operates regardless of whether session logging is also enabled. To configure multiple SyslogD servers, repeat the com­ mand once for each server IP address. (Default: none; Range: Up to six IP addresses)

facility < facility-name >

Specifies the destination subsystem the SyslogD server(s) must use. (All SyslogD servers must use the same subsystem.) HP recommends the default (user) subsystem unless your application specifically requires another subsystem. Options include:

user (the default) - Various user-level messages kern - Kernel messages

mail - Mail system daemon - system daemons

auth - security/authorization messages

syslog - messages generated internally by Syslog lpr - line printer subsystem

news - netnews subsystem uucp - uucp subsystem cron - cron/at subsystem sys9 - cron/at subsystem

sys10 through sys14 - Reserved for system use local0 through local7 - Reserved for system use

(Some switches covered by this manual do not offer the facility option. Refer to the Note on page C-27.)
