In this lab guide I will be discussing how to utilise the logging functionality on a Cisco ASA firewall using the CLI and the ASDM. I will not go through every feature that is possible on the ASA regarding logging, but instead look at the most used features. Lab requirements: -Send syslogs to host 192.168.3.98 at the “Informational†level.
-Buffer syslogs at the “informational†level. The buffer size will be 16384 bytes.
-Diagnose issues by sending certain logs to an SSH session. -Have an accurate timestamp on each syslog. -Send really important syslogs to a mail server at 192.168.3.98. -Log “hits†to ACL statements.
-Enable all syslog messages to have the name of the ASA to be included inside the message. -Do not log message “113019â€.
-Change the severity level of message “315011†to alert.
The ASA will be based upon a 5505 with version 9.1 but a lot of the configuration will work on previous versions of the code and on other ASA platforms.
