Introduction

This document describes an example Embedded Packet Capture (EPC) configuration that captures frames up
to 1550 bytes in a circular capture buffer of 10 megabytes from GigabitEthernet 0/0 and GigabitEthernet 0/1
interfaces.

EPC is an onboard packet capture facility that allows network administrators to capture packets that flow to,
through, or from the device and to analyze them locally or save and export them (to a tool such as Wireshark)
for offline analysis.
