Troubleshooting

Using Logging To Identify Problem Sources

For example, on a switch where there are no SyslogD servers configured, you would do the following to configure SyslogD servers 18.120.38.155 and 18.120.43.125 and automatically enable Syslog logging (with user as the default logging facility):

logging <syslog-ip-addr > configures the Syslog server(s) to use and enables Syslog debug logging. (In this case, Syslog is automatically enabled because debug destination logging has not been previously disabled with other Syslog servers already configured in the switch. (Refer to the Syntax box under “Configuring the Switch To Send Debug Messages to One or More SyslogD Servers” on page C-29.)

The configured Syslog server IP addresses appear in the switch’s configuration file.

This command shows that Syslog logging is enabled for the listed IP addresses.

Default Logging Facility

Figure C-10. Example of Configuring and Enabling Syslog Logging

To use a non-default logging facility, such as lpr, in the same operation as in figure C-10,you would use this command set:

HPswitch(config)# logging 18.120.38.155

HPswitch(config)# logging 18.120.43.125

HPswitch(config)# logging facility lpr
