Troubleshooting
Debug and Syslog Messaging Operation
C-40
Using this command when there are no Syslog server IP addresses
already configured enables both debug messaging to a Syslog server
and the Event debug-type, which means that the switch begins send-
ing Event Log messages to the server, regardless of other debug types
that may be configured.
b. Use the command in step "a" to configure any additional Syslog
servers you want to use, up to a total of six. (When multiple server IP
addresses are configured, the switch sends the selected debug mes-
sage types to all such addresses.)
c. If you want Event Log messages sent to the Syslog server, skip this
step. Otherwise, use this command to block Event Log messages to
the server:
ProCurve# no debug event
2. If you do not want a CLI session for a destination, skip this step.
Otherwise, from the device to which you want the switch to send debug
messages:
a. Use a serial, Telnet, or SSH connection to access the switch's CLI.
b. Execute this command:
ProCurve# debug destination session
3. Enable the debug types for which you want messages sent to the Syslog
server(s) and/or the current session device:
ProCurve# debug < acl | all | event | ip [ospf-opt]>
Repeat this step if necessary to enable multiple debug types.
