Troubleshooting
Debug/Syslog Operation

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

Enables or disables Syslog messaging to the specified IP
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. The
ACL and/or IP-RIP message types will also be sent to the Syslog
server(s) if they are currently enabled as debug types. (Refer
to “Debug Messages” on page C-49.)

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

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

If you use the “

no” form of the command to delete the only

remaining Syslog server address, debug destination logging is
disabled on the switch, but the default Event debug type is not
changed.

Also, removing all configured Syslog destinations with the

no

logging command (or a specified Syslog server destination with
the

no logging < syslog-ip-address > command) does not delete the

Syslog server IP addresses stored in the startup configuration.
To delete Syslog addresses in the startup configuration, you
must enter a

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. (See “Debug Messages” on page C-49.)

To disable Syslog logging on the switch without deleting config­
ured server addresses, enter the

no debug destination logging

command. Note that, unlike the case in which no Syslog servers
are configured, if one or more Syslog servers are already
configured and Syslog messaging is disabled, configuring a
new server address does not re-enable Syslog messaging. To re-
enable Syslog messaging, you must enter the

debug destination

logging command.
