Configure the Splunk Add-on for Cisco ASA on your Splunk Enterprise deployment

To configure the Splunk Add-on for Cisco ASA on your single instance Splunk Enterprise deployment, add inputs from network ports using Splunk Web:

Add a network input using Splunk Web

  1. Click the Add Data link in Splunk Home.
  2. Click Monitor to monitor a network port on the local machine, or Forward to receive network data from another machine.
  3. If you selected Forward, choose or create the group of forwarders you want this input to apply to.
  4. Click Next.

Specify the network input

  1. In the left pane, click TCP / UDP to add an input.
  2. Click the TCP or UDP button to choose between a TCP or UDP input.
  3. In the Port field, enter a port number.
  4. Consult Splunk Support before changing the Source name override value.
  5. If this is a TCP input, specify whether this port will accept connections from all hosts or only one host in the Only accept connections from field. If you only want the input to accept connections from one host, enter the host name or IP address of the host. You can use wildcards to specify hosts.
  6. Click Next to continue to the Input Settings page.

Specify input settings

The Input Settings page lets you specify source type, application context, default host value, and index. All of these parameters are optional.

  1. Set the Source type. Source type is a default field that Splunk Enterprise adds to events and uses to determine processing characteristics, such as timestamps and event boundaries. See the below table to identify applicable sourcetypes.
  2. Set the Host name value. Host only sets the host field in the resulting events. It does not direct Splunk Enterprise to look on a specific host on your network. You have several choices:
    1. IP. Sets the input processor to rewrite the host with the IP address of the remote server.
    2. DNS. Sets the host to the DNS entry of the remote server.
    3. Custom. Sets the host to a user-defined label.
  3. Set the Index that Splunk Enterprise sends data to for this input. Leave the value as default unless you have defined multiple indexes to handle different types of events. In addition to indexes for user data, Splunk Enterprise has a number of utility indexes, which also appear in this dropdown box.
  4. Click Review.

Review your choices

After specifying all of your input settings, review your selections. Splunk Enterprise lists the options you selected, including the type of monitor, the source, the source type, the application context, and the index.

  1. Review the settings.
  2. If they are not what you want, click < to go back to the previous step in the wizard. Otherwise, click Submit.

Splunk Enterprise then loads the "Success" page and begins indexing the specified network input.

See the Cisco documentation for information on how to log specific events in your Cisco ASA deployment.
