Configuring Debug Destinations

A Debug/Syslog destination device can be a Syslog server (up to six maximum) and/or a console session:

■Use the debug destination < logging session buffer > command to enable (and disable) Syslog messaging on a Syslog server or to a CLI session for the debug message types configured with the debug and logging com­ mands (see “Configuring Debug and Event Log Messaging” on page 8-12):

•debug destination logging enables the configured debug message types to be sent to Syslog servers configured with the logging command.

•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.
