Troubleshooting

Using Logging To Identify Problem Sources

Debug and Syslog Operation

You can direct switch debug (Event log) messages to these destinations:

Up to six SyslogD servers

One management-access session through:

A direct-connect RS-232 console CLI session

A Telnet session

An SSH session

Figure C-9. Example of Debug Output to a Console CLI Session

Debug logging requires a logging destination (SyslogD server and/or a session type), and involves the logging and debug destination commands. Actions you can perform with Debug and Syslog operation include:

Configure the switch to send Event Log messages to one or more SyslogD servers. Included is the option to send the messages to the user log facility (default) on the configured servers, or to another log facility.

N o t e

As of August, 2003, the logging facility < facility-name> option (described

 

on page C-29)is available on these switch models:

 

• Switch 2600/2600-PWR Series and the Switch 6108 (software release

 

H.07.30 or greater)

 

• Switch 2800 Series

 

For the latest feature information on HP ProCurve switches, visit the HP

 

ProCurve web site and check the latest release notes for the switch

 

products you use.

 

 

Configure the switch to send Event Log messages to the current manage­ ment-access session (serial-connect CLI, Telnet CLI, or SSH).

Disable all Syslog debug logging while retaining the Syslog addresses from the switch configuration. This allows you to configure Syslog messaging and then disable and re-enable it as needed.

Display the current debug configuration. If Syslog logging is currently active, this includes the Syslog server list.

Display the current Syslog server list when Syslog logging is disabled.
