Interface capture object using triggers

In the following example, you configure a capture object called test-triggeron Fast Ethernet interface 0/1. This object uses FTP traffic as the start trigger and Telnet traffic as the stop trigger.

Note: The filters used in this example are predefined VPN Router filters. If you need a filter that the VPN Router software does not provide, you must create the filter before you configure the capture object.
