Debug Option

event (debug type)
IP (debug type)
Debug commands do not affect normal message output to the
Event Log.
Using the debug event command, you can specify that Event Log messages
are sent to the debug destinations you configure (CLI session and/or
Syslog servers) in addition to the Event Log.
Ensure that your Syslog servers accept Debug messages.
All Syslog messages resulting from a debug operation have a "debug"
severity level. If you configure the switch to send debug messages to a
Syslog server, ensure that the server's Syslog application is configured to
accept the "debug" severity level. (The default configuration for some
Syslog applications ignores the "debug" severity level.)
Duplicate IP addresses are not stored in the list of syslog servers.
If the default severity value is in effect, all messages that have severities
greater than the default value are passed to syslog. For example, if the
default severity is "debug", all messages that have severities greater than
debug are passed to syslog.
There is a limit of six syslog servers. All syslog servers are sent the same
messages using the same filter parameters. An error is generated for an
attempt to add more than six syslog servers.
Effect of a Reboot or Reset
Disabled.
If a Syslog server IP address is configured in the startup­
config file, the sending of Event Log messages is reset to
enabled, regardless of the last active setting.
If no Syslog server is configured, the sending of Event Log
messages is disabled.
Disabled.
