IPv6 Configuration Guide K/KA/KB.15.15

debug destination session
enables the configured debug message types to be sent to the CLI session that executed
this command. The session can be on any one terminal emulation device with serial, Telnet,
or SSH access to the CLI at the Manager level prompt.
debug destination buffer
enables the configured debug message types to be sent to a buffer in switch memory.
• Use the logging [ syslog-ipv6-addr ] command to configure the Syslog server at
the specified IPv6 destination address.
Configuring an IPv6 Syslog Server
Syslog for IPv6 is a client-server logging tool that allows a client switch to send event notification
messages to n IPv6 networked device operating with Syslog server software. Messages sent to a
Syslog server can be stored to a file for later debugging analysis.
To use the Syslog for IPv6 feature, you must install and configure a Syslog server application on
an IPv6 networked host accessible to the switch. See the documentation for the Syslog server
application for instructions.
To configure an IPv6 Syslog server, use the logging [ syslog-ipv6-addr ] command as
described below.
When you configure a Syslog server, Event Log messages are automatically enabled to be sent to
the server. To reconfigure this setting, use the following commands:
• Use the debug command to specify additional debug message types.
• Use the logging command to configure the system module or severity level used to filter the
Event Log messages sent to configured Syslog servers. For more information, see “Configuring
Debug and Event Log Messaging” (page 284).
Logging Command
Syntax
[no] logging syslog-ipv4-address
Enables or disables Syslog messaging to the specified IPv4 address. You can
configure up to six addresses. If you configure an address when none are already
configured, this command enables destination logging (Syslog) and the Event debug
type. Therefore, at a minimum, the switch begins sending 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.
