Troubleshooting
Debug/Syslog Operation
■ Series 2610 switches
■ Series 2600 switches and the Switch 6108 (software release H.07.30 or
greater)
For the latest feature information on ProCurve switches, visit the ProCurve
Networking 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, the list f configured Syslog servers is displayed.
■ Display the current Syslog server list when Syslog logging is disabled.
Configuring Debug/Syslog Operation
1. To use a Syslog server as the destination device for debug messaging,
follow these steps:
a. Enter the logging < syslog-ip-addr > command at the global configura­
tion level to configure the Syslog server IP address and enable Syslog
logging. Optionally, you may also specify the destination subsystem
to be used on the Syslog server by entering the
logging facility
command.
If no other Syslog server IP addresses are configured, entering the
logging command enables both debug messaging to a Syslog server
and the Event debug message type. As a result, the switch automati­
cally sends Event Log messages to the Syslog server, regardless of
other debug types that may be configured.
b. Re-enter the logging command in Step “a” to configure additional
Syslog servers. You can configure up to a total of six servers. (When
multiple server IP addresses are configured, the switch sends the
debug message types that you configure in Step 3 to all IP addresses.)
2. To use a CLI session on a destination device for debug messaging:
a. Set up a serial, Telnet, or SSH connection to access the switch’s CLI.
b. Enter the debug destination session command at the manager level.
3. Enable the types of debug messages to be sent to configured Syslog
servers and/or the current session device by entering the debug < debug-
type > command:
