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 <acl|all|arp-protect|event|ip
[bgp|forwarding|ospf|packet|rip|routemap]|ipv6|
lldp|vrrp>
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-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 >
Caution 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
