IPv6 Diagnostic and Troubleshooting

Debug/Syslog for IPv6

debug destination buffer enables the configured debug message types to be sent to a buffer in switch memory.

Logging Command

Syntax: [no] logging < syslog-ipv4-addr >

Enables or disables Syslog messaging to the specified IPv4 address. You can configure up to six addresses. If you config­ ure an address when none are already configured, this com­ mand enables destination logging (Syslog) and the Event debug type. Therefore, at a minimum, the switch begins send­ ing Event Log messages to configured Syslog servers. If other debug message types are configured, they are also sent to the Syslog server.

no logging removes all currently configured Syslog logging destinations from the running configuration.

no logging < syslog-ipv4-address> removes only the specified Syslog logging destination from the running configuration.

Note: The no logging command does not delete the Syslog server addresses stored in the startup configuration. To delete Syslog addresses in the startup configuration, you must enter the no logging command followed by the write memory command. To verify the deletion of a Syslog server address, display the startup configuration by entering the show config command.

To block the messages sent to configured Syslog servers from the currently configured debug message type, enter the no debug

<debug-type > command.

To disable Syslog logging on the switch without deleting con­ figured server addresses, enter the no debug destination logging command.

For complete information on how to configure a Syslog server and Debug/ Syslog message reports, refer to the “Troubleshooting” appendix in the Man­ agement and Configuration Guide.
