Troubleshooting
Debug/Syslog Operation
A Debug/Syslog destination device can be a Syslog server and/or a console
session. You can configure debug and logging messages to be sent to:
■ Up to six Syslog servers
■ A CLI session through a direct RS-232 console connection, or a Telnet or
SSH session
Debug/Syslog Configuration Commands
Event
Notification
Logging — Automatically sends switch-level event messages to the switch’s Event Log. Debug and
Syslog do not affect this operation, but add the capability of directing Event Log
messaging to an external device.
logging
Command
< syslog-ip-addr > Enables Syslog messaging to be sent to the specified IP address.
facility (Optional) The logging facility command specifies the destination (facility) subsystem
used on a Syslog server for debug reports.
severity Sends Event Log messages of equal or greater severity than the specified value to
configured debug destinations. (The default setting is to send Event Log messages from
all severity levels.)
system-module Sends Event Log messages from the specified system module to configured debug
destinations. The severity filter is also applied to the system-module messages you select.
The default setting is to send Event Log messages from all system modules. To restore
the default setting, enter the
no logging system-module < system-module > or logging
system-module all-pass commands.
debug
Command
all Sends debug logging to configured debug destinations for all Event Log and IP-RIP
options.
destination logging: Disables or re-enables Syslog logging on one or more Syslog servers configured
with the logging < syslog-ip-addr > command. See “Debug Destinations” on page C-45.
session: Assigns or re-assigns destination status to the terminal device that was most
recently used to request debug output. “Debug Destinations” on page C-45.
buffer: Enables Syslog logging to send the debug message types specified by the debug
< debug-type > command to a buffer in switch memory. See “Debug Destinations” on
page C-45
.
event Sends standard Event Log messages to configured debug destinations. (The same
messages are also sent to the switch’s Event Log, regardless of whether you enable this
option.)
ip forwarding: Sends IPv4 forwarding messages to the debug destination(s).
packet: Sends IPv4 packet messages to the debug destination(s).
