Logging Overview

The FWSM supports the generation of an audit trail of syslog messages that describe its activities (for
example, what kinds of network traffic has been allowed and denied) and enables you to configure
system logging.
All syslog messages have a default severity level. You can reassign a message to a new severity level, if
necessary. When you choose a severity level, logging messages from that level and lower levels are
generated. Messages from a higher level are not included. The higher the severity level, the more
messages are included. For more information about logging and syslog messages, see Catalyst 6500
Series Switch and Cisco 7600 Series Router Firewall Services Module System Log Messages.
