Configuring and Managing Syslog Messages Chapter 25 Monitoring the Firewall Services Module Step 2 To specify the number of syslog messages retained in the ASDM log buffer, enter the following command: hostname(config)# logging asdm-buffer-size num_of_msgs where num_of_msgs specifies the number of syslog messages that the FWSM retains in the ASDM log buffer. The following example shows how to set the ASDM log buffer size to 200 syslog messages: hostname(config)# logging asdm-buffer-size 200 Clearing the ASDM Log Buffer To erase the current contents of the ASDM log buffer, enter the following command: hostname(config)# clear logging asdm Sending Syslog Messages to a Switch Session, Telnet Session, or SSH Session When you log in to the FWSM from the switch, you are connected using a Telnet session. Therefore, you configure logging to a switch session the same way as you configure logging to a Telnet or SSH session. Viewing syslog messages in a Telnet or SSH session requires two steps: 1. Specify which messages should be sent to a Telnet or SSH session. 2. View syslog messages in the current session. This section includes the following topics: • Configuring Logging for Telnet and SSH Sessions, page 25-8 • Viewing Syslog Messages in the Current Session, page 25-9 Configuring Logging for Telnet and SSH Sessions Note To start logging to a Telnet or SSH session as defined in this procedure, be sure to enable logging for all output locations. See the "Enabling Logging to All Configured Output Destinations" section on page 25-2. To disable logging, see the "Disabling Logging to All Configured Output Destinations" section on page 25-3. To specify which messages should be sent to a Telnet or SSH session, enter the following command: hostname(config)# logging monitor {severity_level | message_list} Where the severity_level argument specifies the severity levels of messages to be sent to the session. You can specify the severity level number (0 through 7) or name. For severity level names, see the "Severity Levels" section on page 25-20. For example, if you set the severity level to 3, then the FWSM sends syslog messages for severity levels 3, 2, 1, and 0. The message_list argument specifies a customized message list that identifies the syslog messages to send to the session. For information about creating custom message lists, see the "Filtering Syslog Messages with Custom Message Lists" section on page 25-14. 25-8 Catalyst 6500 Series Switch and Cisco 7600 Series Router Firewall Services Module Configuration Guide using ASDM OL-20748-01
