Embedded Packet Capture (EPC) is a packet capture facility that allows network administrators to capture packets flowing to, through, and from the device and to analyze them locally or save and export them for offline analysis by using a tool such as Wireshark. EPC simplifies network operations by allowing devices to become active participants in the management and operation of the network. This feature facilitates troubleshooting by gathering information about the packet format. This feature also facilitates application analysis and security.

Step1: Define a 'capture buffer' with the specified name and parameters, which are a temporary buffer that captured packets, are stored within. There are various options that can be selected when the buffer is defined.
