Troubleshooting
Debug/Syslog Operation
ProCurve# debug
[bgp|forwarding|packet|rip|routemap]|ipv6| lldp>
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-module followed 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-27.
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 >
C a u t i o n
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
saved after a system reboot (power cycle or reboot) and re-activated on the
switch. As a result, after switch startup, one of the following situations may
occur:
■
Only a partial set of Event Log messages may be sent to configured debug
destinations.
■
Messages may be sent to a previously configured Syslog server used in an
earlier debugging session.
