Debug/Syslog Operation

Debug/Syslog Configuration Commands

Event

—

Automatically sends switch-level event messages to the switch’s Event Log. Debug

Notification

 

and Syslog do not affect this operation, but add the capability of directing Event Log

Logging

 

messaging to an external device.

 

 

 

logging

<syslog-ip-addr>

Enables Syslog messaging to be sent to the specified IP address.

Command

 

 

 

facility

(Optional) The logging facility command specifies the destination (facility)

 

 

subsystem used on a Syslog server for debug reports.

 

priority-desc

A text string associated with the values of facility, severity, and system-module.

 

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

all

Sends debug logging to configured debug destinations for all Event Log options.

Command

 

 

 

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-40.

 

 

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-40.

 

 

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-40.

 

 

windshell: print debug messages to windshell.

 

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).

 

 

rip: Sends RIP event logging to the debug destination(s).

 

ipv6

dhcpv6-client:Sends DHCPv6 client debug messages to the configured debug

 

 

destination.

 

 

forwarding: Sends IPv6 forwarding messages to the debug destination(s)

 

 

nd: Sends IPv6 debug messages for IPv6 neighbor discovery to the configured

 

 

debug destination(s).

 

 

packet: Sends IPv6 packet messages to the debug destination(s).
