本文描述从 GigabitEthernet 0/0 和 GigabitEthernet 0/1 接口在 10 兆字节环形捕获缓冲区中捕获多达 1550 字节的帧的嵌入式数据包捕获 (EPC) 配置示例。
EPC 是一个允许网络管理员捕获流向、流经此设备或从此设备流出的数据包并在本地分析或保存并导出这些数据包进行离线分析的内置数据包捕获设备。

此配置从 GigabitEthernet 0/0 和 GigabitEthernet 0/1 接口在 10MB 环形捕获缓冲区中捕获多达 1550 字节的帧。
!-- Define a capture buffer.
monitor capture buffer pcap-buffer1 size 10000 max-size 1550
!-- Define a capture point.
monitor capture point ip cef pcap-point1 g0/0 both
monitor capture point ip process-switched pcap-point2 both
!-- Associates the capture point with the capture buffer
!-- so that packets captured from the specified capture
!-- point can be dumped to the associated capture buffer.
monitor capture point associate pcap-point1 pcap-buffer1
monitor capture point associate pcap-point2 pcap-buffer1
!-- Repeat the same steps for second interface.
monitor capture buffer pcap-bufferA size 10000 max-size 1550
monitor capture point ip cef pcap-pointA g0/1 both
monitor capture point ip process-switched pcap-pointB both
monitor capture point associate pcap-pointA pcap-bufferA
monitor capture point associate pcap-pointB pcap-bufferA
!-- Optionally you can specify an access-list in order to capture
!-- only interesting traffic as defined by access-lists 110 and 120.
monitor capture buffer pcap-buffer1 filter access-list 110
monitor capture buffer pcap-bufferA filter access-list 120
!-- Enable the capture point in order to start packet data capture.
monitor capture point start pcap-point1
monitor capture point start pcap-point2
monitor capture point start pcap-pointA
monitor capture point start pcap-pointB
!-- Verify the configuration.
show monitor capture point all
show monitor capture buffer all
!-- Disable the capture point, and stop the packet data capture process.
monitor capture point stop pcap-point1
monitor capture point stop pcap-point2
monitor capture point stop pcap-pointA
monitor capture point stop pcap-pointB
!-- Export the data for analysis.
monitor capture buffer pcap-buffer1 export tftp://192.0.2.100/1.cap
monitor capture buffer pcap-bufferA export tftp://192.0.2.100/A.cap
