Chapter 1 Configuring System Message Logging and Smart Logging
Configuring Smart Logging
To remove a syslog server, use the no logging host global configuration command, and specify the syslog
server IP address. To disable logging to syslog servers, enter the no logging trap global configuration
command.
Table 1-4 lists the UNIX system facilities supported by the software. For more information about these
facilities, consult the operator’s manual for your UNIX operating system.
Configuring Smart Logging
Smart logging provides a mechanism to capture and export packet flows based on predefined or
user-configured triggers. Beginning with Cisco IOS Release 12.2(58)SE, the switch supports smart
logging for these events:
• DHCP snooping violations
•
Dynamic ARP inspection violations
• IP source guard denied traffic
•
ACL permitted or denied traffic
To use smart logging, you must first configure a NetFlow exporter that you identify when you enable
smart logging. For information on configuring Cisco Flexible NetFlow, see the
Cisco IOS Flexible
NetFlow Configuration Guide, Release 12.4T :
