Introduction
Cisco Application and Content Networking Software (ACNS) 4.2.1 introduced the tcpdump command. This
command enables you to gather a sniffer trace on the Content Engine, Content Router, or Content Distribution
Manager for the purpose of troubleshooting, when asked to gather the data by the Cisco Technical Support.
This utility is very similar to the Linux/Unix tcpdump command.
