Troubleshooting

Debug/Syslog Operation

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:

ProCurve# debug <aclallarp-protecteventip [bgpforwardingospfpacketriproutemap]ipv6 lldpvrrp>

Repeat this step if necessary to enable multiple debug message types.

By default, Event Log messages are sent to configured debug destination devices. To block Event Log messages from being sent, enter the no debug event command.

4. If necessary, enable a subset of Event Log messages to be sent to config­ ured Syslog servers by specifying a severity level and/or system module using the following commands

ProCurve(config)# logging severity < debug major error warning info > ProCurve(config)# logging system-module< system-module>

To display a list of valid values for each command, enter logging severity or logging system-modulefollowed by ? or pressing the Tab key.

The severity levels in order from the highest to lowest severity are: major, error, warning, info, debug. For a list of valid values for the logging system- module <system-module> command, refer to Table C-1 on page C-28.

5. If you configure system-module and/or severity-level values to filter Event

 

Log messages, when you finish troubleshooting, you may want to reset

 

these values to their default settings so that the switch sends all Event Log

 

messages to configured debug destinations (Syslog servers and/or CLI

 

session).

 

To remove a configured setting and restore the default values that send

 

all Event Log messages, enter one or both of the following commands:

 

ProCurve(config)# no logging severity < debug major error warning info>

 

ProCurve(config)# no logging system-module < system-module>

If you configure a severity-level, system-module, logging destination, or

 

logging facility value and save the settings to the startup configuration (for

 

example, by entering the write memory command), the debug settings are
